David Velez-Osomo

Thank you, Jorg. Good evening, everyone, and thank you again for being with us today. In Q1 2024, we kick started the year with many ambitious goals aimed at propelling our platform to the next level. As we shared with you last quarter, we're targeting 4 key priorities for 2024, all aligned with our mission to find complexity and empower people: First, establish strong momentum in Mexico, which means creating the basis for us to grow sustainably and profitably in the country; second, ramp up our secure lending initiatives in Brazil; third, enhance our strategies to further advance in the high-income segment in Brazil; and fourth, launch products and services to leverage technologies such as real-time payments, open banking and AI that will turn the concept of our consumer technology-driven money platform into a reality for our customers.
Beginning this quarter, we will present data points to demonstrate the progress of select priorities. During Q1 2024, our business model, anchoring 3 fundamental principles: fast customer expansion; expanding revenue per customer; and efficient operating costs showed its strength once again as we generated significant earnings. The growth of our customer base on a net add basis continues to exceed our expectations, surpassing 99 million customers at the end of the quarter, expanding 67% from the 59 million recorded just 2 years ago.
In fact, we've recently announced surpassing the milestone of 100 million customers, becoming the first digital banking platform outside of Asia to cross this remarkable number and operating still in only 3 countries in Latin America. The rate of customer net adds in Brazil continues to be impressive, averaging 1.3 million customers per month, resulting in a total of 91.8 million customers at the end of the first quarter of 2024.
In parallel, our growth in Mexico has reaccelerated with a net add of almost 1.5 million new customers in the quarter, reaching a total of 6.6 million customers by the end of Q1. This growth underscores the success of our decision to increase the positive yields in Mexico, which has accelerated our flywheel and solidified Nu's position as the unrivaled leader in the digital banking category in Mexico.
Finally, let me share some financial highlights with you. In the quarter, our revenues surged to $2.7 billion, accelerating sequentially to a 64% year-over-year increase. Our gross profit surpassed $1.2 billion, growing 76% year-over-year, while our gross margin reached 43.2% in the quarter. Despite expected contraction of our gross margins this quarter from a seasonal high in Q4, as flagged during our prior earnings call, our net income expanded again quarter-over-quarter to $379 million, while we achieved adjusted net income of $443 million, reflecting expansions of 160% and 136% year-over-year, respectively.
This showcases the strength of our business model, capable of combining strong online growth with consistently very solid levels of profitability. This slide encapsulates our financial performance trends over the past 2 years, underscoring our momentum and consistent success in expanding our customer base while simultaneously accelerating both revenues and profitability. The robust growth for our customer base, driven by the growing cross-selling and upselling opportunities enabled by our highly engaged platform led to more than threefold increase in quarterly revenues within just 2 years on an FX-neutral basis.
This translated into a 75% annual compounded growth rate for this period. The third chart on this slide effectively illustrates our robust pricing and underwriting capabilities, where quarterly gross profit is calculated as total revenues minus funding costs, transactional expenses and credit loss allowances increased by almost 4x in the same period.
Lastly, the combined impact of the aforementioned factors, coupled with the strong operating leverage of our platform and the maturation of our early products in Brazil, has led to a significant acceleration in net income growth. This upward trajectory is evident in the chart on the right, especially over the past 2 years. We anticipate this compounding effect to persist in the years ahead, driven by the combination of sustained growth and increased profitability within our platform.
Now I'd like to highlight how our flywheel, not only drives customer acquisition and data growth, but also sustains strong momentum in our key financial metrics. As we continue to expand in our 3 markets, leveraging the inherent operating advantage of our model, our holding company has successfully transformed its potential into profits.
In the first quarter of the year, Nu Holdings achieved an adjusted net income of $443 million, reflecting an adjusted annualized return on equity of 27%. We believe that this performance surpasses that of most peers in the region, despite maintaining a considerable excess capital of $2.4 billion at the holding level and with 2 subsidiaries in Mexico and Colombia that are still operating with negative profitability. If one were to look at our operations in Brazil alone, our return on equity remained well above 40%.
As outlined at the outset of this call, we are committed to providing investors in the market in general with updates on our progress regarding our 4 key priorities for 2024. For this quarter, we have chosen to present KPIs specifically related to our first priority, Mexico. In this slide, we highlight the considerable momentum our strategy in Mexico has achieved, evidenced by the acceleration of our flywheel in the country. Notably, Mexico is already surpassing Brazil in terms of time to achieve different key KPIs for the business.
This slide was built analyzing quarterly figures in Mexico in Q1 '24, marking 19 quarters since our launch in Mexico and compares the status of our operations in Brazil at the same point in time. After just 1 year since the launch of Cuenta Nu, Mexico has already surpassed Brazil in both absolute number of customers and checking account holders as well as in relative terms when considering market share figures. Equally impressive is the progress for credit card franchise in Mexico.
Surpassing the milestone of 3 million credit card customers, we believe our user numbers have outpaced those of some of the top 3 incumbent banks in the country. Notably, Nu Mexico has already attained $1.6 billion in credit card purchase volume, representing a 6.1% market share in the country compared to a 4.3% share in Brazil during the same period. When looking into deposits, we have just crossed the mark of $2.3 billion of retail deposits, more than double the amount at the end of 2023 and representing 1.2% share of total deposits in Mexico compared to the 0.5% we had in Brazil at the same time.
The aforementioned KPIs dropped $149 million in total revenues for Mexico this quarter, which compared to $99 million for Brazil in the same time frame. We're thrilled with our performance in the early months of 2024 and are well positioned to achieve the goals we have set for ourselves for the year.
The developments we've shared suggest that we are building a model that could be successfully exported, a feat many previously deemed unachievable in consumer finance. While we acknowledge that there are still many hurdles to overcome, we remain incredibly excited about the early stages of these model's development. Having successfully balanced growth and profitability in Brazil, we now aspire to extend these traits beyond our initial borders.
Now I'd like to pass the floor to our CFO, Guilherme Lago, who will guide you through our financial numbers. Over to you, Lago.

Guilherme Marques do Lago

Thank you, David, and good evening, everyone. As David mentioned, we delivered a strong first quarter in both operating and financial KPIs. Those results were achieved by focusing on our simple yet powerful value-generating strategy, which can be summarized by 3 guiding pillars: First, a focus on growing our customer base in the 3 markets where we operate and rapidly converting our new customers into active customers; second, expanding average revenue per active customers, or ARPAC, through both cross-selling and upselling; and third, continuing to deliver high growth while maintaining one of the lowest operating costs in the industry.
Now let's delve further into our first quarter results to gain a deeper understanding on the progression of each one of these pillars. I will begin with the results of our customer acquisition. During the first quarter of 2024, our customer base continued to increase at a solid pace. We accelerated customer growth quarter-over-quarter, welcoming 5.5 million new customers in the first quarter of 2024 for a total of 99.3 million customers at quarter end, a 26% increase year-over-year.
In Brazil alone, our customer growth pace is at approximately 1.3 million customers per month with the vast majority still coming from referrals. This not only translates into lower acquisition costs, but also ensures faster activation, showcasing the trust and satisfaction our customers have in our services. Our client base in both Mexico and Colombia also experienced strong positive growth.
In Mexico, we reached 6.6 million customers this quarter, marking a remarkable 106% year-over-year growth and surpassing last quarter's net additions. Additionally, we now serve more than 900,000 customers in Colombia. Once we add customers, our goal is to activate and retain them. Our active customer base has increased by 27% year-over-year, followed by another sequential quarterly increase in the monthly activity rate, which now stands at 83.2%, up from 82.1% just 1 year ago. This marks the tenth consecutive increase in this metric. We believe that this is a testament to our proficiency in engaging customers effectively on our platform.
Turning our attention to revenue expansion. The first chart highlights that Nu has established primary banking relationships with around 59% of our active customer base. The drop of 2 percentage points in comparison to the fourth quarter of 2023 is mainly associated with last quarter's seasonality, considering increased transactionality during the month of December. Nevertheless, the 2 following charts show an increase in both the number of products per active customer and ARPAC.
As you can see in the second chart, the number of products per active customers grew from an average of 4 last quarter to 4.1 this quarter, illustrating our successful cross-selling strategy achieved by introducing new products to our customers and establishing ourselves as their primary banking partner. The last chart shows the combined effect of these 2 dynamics. By having significant customer engagement, as demonstrated in the first chart, together with our growing product cross-sell capabilities, as shown in the second chart, it produces increasingly positive results.
Our monthly ARPAC increased to $11.4 this quarter in comparison to $10.6 just 1 quarter ago. Our more mature cohorts are already generating a monthly ARPAC of $27. This reported increase in ARPAC resulted in another quarter of solid revenue growth as presented in the next slide. Our monthly ARPAC grew sequentially and accelerated its year-over-year expansion rate to 30%, reaching $11.4, up from $8.6 just 1 year ago. As discussed in prior earnings calls, we maintain confidence in further growing ARPAC going forward towards its full potential.
In the second chart, we illustrate our revenues hit a new record high this quarter, reaching $2.7 billion, up 64% year-over-year. Just a year ago, our revenue was $1.6 billion. This growth was driven by the increase in active clients, combined with higher ARPAC levels. Now let's discuss our cards business in more detail. It's important to remember that for cards, the purchase volumes are seasonal, higher in the fourth quarter and lower in the first quarter of every year. Historical seasonality analysis shows a drop of 6.9% on average in total purchase volume for the industry.
However, the sequential reduction in Nu's purchase volume this quarter was only 3.7%, with especially strong performance in credit cards, which contracted only 1.8% on an FX-neutral basis versus the historical industry seasonality drop of 5.9%. Compared to the first quarter of last year, our purchase volume was up 30% on an FX-neutral basis to $31.1 billion, sustaining its very strong growth path.
On the right side, the chart shows how purchase volumes expand as cohorts of customers develop and mature. Older cohorts continue to increase purchase volumes. While an initial disparity does exist between newer and older cohorts, both tend to exhibit an upward trend in consumption over time. We expect that the compounding effect of adding millions of customers each month, along with the maturation of new customers into historically observed spending patterns, will strongly support the growth of future purchase volumes at Nubank.
Talking about purchase volumes trend for the industry, we believe Nu ended the first quarter of 2024 with a market share of around 15%, including credit, debit and prepaid cards. As we continue to attract millions of new customers every quarter and their spending matures over time, our confidence in our ability to capture additional market shares in the future only grows.
This quarter, our consumer finance portfolio, comprising credit cards and personal loans, posted another acceleration, growing 52% year-over-year and reaching $19.6 billion. This growth was boosted by expansions in both product categories. The credit card portfolio expanded sequentially, growing by 42% year-over-year to $15.1 billion. This growth was driven by the combined effect of onboarding new customers and increasing the share of wallet of existing customers across all segments. For yet another quarter, our personal loan portfolio was a highlight, increasing 88% year-over-year and reaching $4.5 billion. Following the consistent trends observed in previous quarters, our personal loan cohorts have continued to exhibit expected credit behaviors, which has enabled us to continue to scale originations.
Now let's move to the breakdown of interest-earning loans within our credit card portfolio. Interest-earning installment balances now account for 26% of our total credit card portfolio, up from 23% last quarter. This sequential growth was mainly underpinned by the successful expansion of our PIX and boletos financing products. As we previously mentioned, we believe that this type of financing offers an attractive risk-adjusted rate of return, allowing us to further expand the monetization of our credit card business, while also unlocking substantial value as we fulfill an important customer need.
This strategy is reinforced by the fact that our share of revolving receivables has not increased, representing 6% of our total receivables again this quarter. Delving into our personal loan business, our portfolio composed of both unsecured and secured loans remains aligned with our expectations for asset quality. Originations reached BRL 12.3 billion in the quarter with secured personal loans growing according to plan and originations reaching BRL 1.7 billion, almost doubling versus the prior quarter. This represents 14% of the total originated versus 10% in the previous quarter.
As discussed in the previous earnings call, we are very pleased to note significant progress in broadening our lending portfolio. We have introduced payroll loans for federal public servants and retirees, FGTS anticipation and investment-backed loans. Although still ramping up, this portfolio should contribute to the development of an even more resilient credit book in the years to come.
Following the same trend as last quarter, our credit yield was affected by the loan mix as secured personal loans have lower interest rates and increase in originations of these loans directly impact the average interest rate of our personal loan portfolio. This decrease in credit yield was only partially offset by a slight increase in the unsecured lending yield as a result of our continued risk expansions.
Now let's review the progress achieved on the funding front. It's important to remember that fourth quarters are seasonally strong in deposit inflows, while first quarters are seasonally weak, representing a historical drop of approximately 4.6%. While we noted an expected decrease in deposits in Brazil, the total for the quarter of our deposits base increased and reached $24.3 billion, representing a 53% year-over-year growth, mainly driven by Mexico, where we are experiencing significant growth in Cuenta Nu.
By the end of the first quarter of 2024, we achieved over $2 billion in deposits in Mexico, more than doubling when compared to last quarter. Similar to Brazil, this growth represents a very significant milestone towards our goal of developing one of the strongest local currency retail deposit franchise in the region, bolstering our ability to support our consumer finance operations across all of the geos where we operate. Our cost of deposits, defined as the ratio between the interest income paid to customers and the interbank rate of the respective markets, namely TIIE for Mexico and CDI for Brazil, was 84% of the interbank rate, very much in line with our expectations.
The increase in cost of deposits this quarter is directly linked to the growth of our franchise in Mexico. We believe this consistently low cost of deposits highlights our progress in harnessing the value of our liability franchise. Our loan-to-deposit ratio, or LDR, stood at 40% versus 34% in the previous quarters with deposit growth accelerating sequentially. We are very confident that there is still a lot of room for additional balance sheet optimization.
Net interest income, or NII, nearly doubled year-on-year, reaching another record high of $1.6 billion. This was driven by the growth of our credit card and lending portfolios, which collectively have propelled the expansion of our NII and of our net interest margins, or NIM, to new record highs. For the first quarter of 2024, we delivered a net interest margin of 19.5%, representing an increase of 1.2 percentage points compared to last quarter and a 4.5 percentage points in comparison to 1 year ago.
As we look ahead and irrespective of the direction of interest rates, we believe that the main lever for future NIMs should be the progression of the company's loan-to-deposit ratio. As our excess deposits are invested in public bonds, the remuneration of which is much lower than those of our credit products. Let's turn our attention to the last pillar of our overall strategy, maintaining a low cost-to-serve. We maintain our conviction that our platform is one of the most cost-effective in catering to customers within our operating markets with its low cost-to-serve standing as a significant competitive advantage.
That is the reason we aim at keeping it at or below $1 level for the foreseeable future. For yet another quarter, we were successful in achieving this goal with a cost-to-serve per active customer standing at $0.90. This figure currently remains unchanged on an FX-neutral basis when compared to a year ago, while our ARPAC, as mentioned earlier, increased by 30%, demonstrating the strong operating leverage of our business model. Our gross profit reached a new quarterly record high at approximately $1.2 billion, a 76% year-over-year increase.
As we mentioned during our last earnings call, we expected annualized gross margins to normalize to levels of 2023 as our investments in Mexico and Colombia are offset by the positive trends expected for Brazil. The sequential drop in gross profit margins in the first quarter was driven by 2 main factors: Number one, the seasonal drop in cards purchase volumes, which impacted interchange revenues when compared to the fourth quarter; and number two, the increase in growth, which drove credit loss allowance billed in the quarter. Yet, our gross profit margins reached 43.2% this quarter, an increase of 3 percentage points in comparison to 1 year ago.
One of the key elements of our strategy is achieving operating leverage. Our efficiency ratio stood at 32.1% during the first quarter of 2024, an improvement of almost 4 percentage points in relation to the last quarter of 2023 and almost 7 percentage points better than 1 year ago. Please recall that during the fourth quarter of 2023, our efficiency ratio was impacted by higher marketing expenses, mainly due to the phasing of this cost into the end of the year, together with higher cloud expenses, driven by seasonal increases in data usage in the quarter.
As we mentioned at the time, we believe that our efficiency ratio would come to normalize during the following quarters, as demonstrated during this first quarter of 2024. We continue to believe that this positions Nu as one of the most efficient financial services companies in the world. We expect to benefit from the full potential of our platform's operating leverage as we continue to grow our customer base, upsell and cross-sell products, launch new features and eventually achieve profitability in the new geos of Mexico and Colombia, which are still in their investment phases.
Let's now review the sustainable advantages across our 4 cost pillars: Number one, our cost to acquire was stable at $7, an amount we continue to believe to be one of the lowest among consumer fintechs and banks globally; number two, our cost-to-serve remained as expected at a low level, below $1, which we estimate to be approximately 85% lower than those of incumbent banks. Once again, we believe this level of cost to serve makes Nu one of the most efficient financial services companies in the world.
Number three, on cost of risk, again, we have effectively managed credit risk outperforming competitors on an apples-to-apples basis in terms of delinquency rates; and finally, number four, on the cost of funding, while significantly increasing deposit volumes, we were able to maintain our cost of funding at a competitive level of 84% of the blended interbank rates of Brazil and Mexico, thus closing the negative gap against incumbent banks and widening the positive gap over consumer fintechs.
And finally, moving to net income. We delivered another quarter of profitability with a net income of $379 million, increasing by 160% compared to the previous year. This strong and positive results serve as an evidence of the effectiveness of our strategy and business model. Additionally, adjusted net income reached $443 million in the quarter and 136% increase when compared to 1 year ago. While we are encouraged by the first quarter results, it's again important to emphasize our commitment to managing our business for long-term value creation. This may require undertaking material short-term investments aimed at optimizing our long-term opportunities.
Now I would like to hand the call over to Youssef, our President and Chief Operating Officer, who will walk you through the key highlights of our asset quality.

Youssef Lahrech

Thank you, Lago. Good evening, everyone. I will now take you through some of the highlights of asset quality and credit portfolio health for the first quarter of 2024. Let us start with NPL trends. First, let me remind you that seasonally, the first quarter represents a high point for early-stage delinquencies. Specifically, 15 to 90 NPLs rise on average by 80 basis points between Q4 and Q1 based on historical data, in line with the rest of the market. That being said, our leading indicator, NPL 15 to 90, increased to 5% in the first quarter of 2024, broadly in line with expectations.
Second, our 90-plus NPL ratio increased slightly to 6.3%, also in line with expectations. This is a result of the normal flow through the delinquency buckets. Considering that, as we discussed in the past, 90-plus is a stock rather than flow metric, so over time, you get a stacking dynamic. And since we haven't sold any delinquent loans, our NPL rates require no adjustment.
As we've mentioned in previous calls, we continue to see meaningful opportunities to expand our credit portfolio, aiming for attractive returns and robust resilience. Part of that growth has been coming from expansions than the credit spectrum, which will continue to result in intentionally higher delinquency rates and will continue to be more than offset by additional revenues leading to increasing risk-adjusted margins over time. To illustrate the impact of the credit expansion dynamic on our consumer finance portfolio, we're sharing here this analysis of NPLs as a ratio of interest-earning balances only as opposed to total balances in the previous slide.
As you can appreciate, Nu's NPLs as a ratio of interest-earning balances have been trending significantly down on both 15 to 90 and 90-plus. In other words, as we've expanded our credit portfolio, we have increased interest-earning balances at a faster rate than NPLs, thus enhancing returns and resilience. Our provisions continue to grow, primarily driven by the growth in our portfolio, following the same dynamic as in prior quarters. This is, again, due to the fact that we front-load provisions when we originate loans in accordance with IFRS 9's expected loss methodology.
Our credit loss allowance expenses grew to $831 million this quarter, directly linked to the increased volumes of origination we generated in the quarter. As a reminder, last quarter, we incurred a lower credit loss allowance expense. That suppression was driven by higher credit card and personal loan recoveries as a result of the Desenrola government-sponsored debt renegotiation program in Brazil, combined with other collections initiatives.
Risk-adjusted NIM reached 9.5% in the quarter, up 3.2 percentage points from a year ago, although contracting 70 basis points quarter-on-quarter. The risk-adjusted NIM was directly impacted by the increase of provisions linked to the growth of our portfolio, particularly in Brazil and by the growth of our deposits in Mexico. Excluding these 2 effects, our risk-adjusted NIM would have been virtually changed versus the past quarter. With that, we're now ready to address your questions. Thank you very much.

Question and Answer Session

Operator

(Operator Instructions) I would like to turn the call over to Mr. Jorg Friedemann, Investor Relations Officer.

Jorg Friedemann

Our first question comes from the line of Tito Labarta at Goldman Sachs.

Daer Labarta

My question is on the increase in provisions. I understand part of it, Desenrola impacted 4Q, so expecting some part of an increase. But if you can maybe delineate a little bit more the sharp increase in the quarter. Is it a function of the loan mix, thinking interest-bearing credit card portfolio increased more, personal loans increased a lot? And did Mexico have any impact on the provisioning? Just to think about -- how we should think about it going forward as well.

Youssef Lahrech

Tito, thanks for your question. So in terms of the provision dynamics and the provision build we saw in the quarter, you're definitely correct to point out that last quarter was a little bit abnormally low because of the Desenrola we had indicated about $60 million to $70 million additional recoveries during the quarter. So you have to think about over last quarter with that in mind. This quarter, we were back to what I would describe as more normal levels that reflect the dynamics of the portfolio. So we've experienced a lot of growth in both lending, secured and unsecured as well as credit card.
Some of that growth, as [I pointed out earlier], comes from credit expansions, and we've typically seen that play out per expectations, if not actually slightly better than our expectations in terms of the returns. So we're very happy with the NPV and the returns we're getting from those expansions, and you can see that reflected in the risk-adjusted NIM, growing 320 basis points year-on-year.
With respect to Mexico, in fact, in Mexico, what we're seeing in the last couple of quarters is improvements in NPLs, partly because of the underwriting improvements we've made at our models, more data. There's more experience in the market and then partly because of a better mix of customers we've been getting over the last couple of quarters after repricing the Cuenta yield up. So Mexico has been probably a positive driver rather than not on that front.

Daer Labarta

Great. That's helpful. And my follow-up, I guess, on the risk-adjusted NIM, you mentioned it would have been stable-ish sort of quarter-over-quarter adjusting for Desenrola. Is that sort of maybe what we should expect for the full year? Or do you think there can be some risk-adjusted NIM expansion throughout the year? I know you don't give guidance, but just how you think that should evolve, to some extent, would be helpful.

Youssef Lahrech

Yes, sure. So Tito, you're correct. Like, the risk adjusted NIM going forward will reflect kind of dynamics of the portfolio -- the credit portfolio going forward. If we -- like we have, over the last couple of quarters, continue to see opportunities to expand. That would come with enhanced margins, right? But we, as you pointed out, don't give guidance on that nor try to forecast that with any degree of precision.

Jorg Friedemann

And our next question comes from the line of Thiago Batista from UBS.

Thiago Bovolenta Batista

I have a question about the SME business of Nu. We saw that Nu achieved more than 4 million clients in the SME business, something close to 2.4 active clients in this segment. When I look at Central Bank data, Nu is charging about 9%, 10% per month in these short-term working capital loans. This is probably a very small portfolio for Nu right now. But can you share with us Nu's strategy in this segment? And how big this can be in the future?

David Velez-Osomo

Thank you for the question. So you're right. We actually haven't really talked publicly that much about our growth on the SME side, but it is a significant opportunity ahead of us. And partly, this opportunity has come to fruition as we started to cross-selling SME account to our large consumer base. So just to give you one data point, out of the 93 million or so Brazilian customers that we have, we think we have in our base, something like 8 million or 9 million small businesses, and that's a significant percentage of something like 15 million of total businesses existing in Brazil.
So already in our base, we have a path towards pretty significant operation with more businesses. We, by the way, see that they tend to be very badly served also, especially if they are owned by 1 shareholder or 2 shareholders. So as we call here in Brazil, [May]. So this is a big opportunity that we've been developing as it has grown consistently. Today, our value proposition is fairly basic. We began with an account for the small business, then we launched a debit card.
We have already started growing for a few quarters, the credit card for the small business. This is a product that we're very excited about because we get to use a lot of the credit and the rating data that we have on the consumer side for the small business side. There actually is a lot of synergies in using a lot of the data for both sides of the consumer. It allows us to see a consumer more -- on a more complete basis.
And we also see that when we start banking somebody both on the consumer side as well as the small business, we see a pretty significant increase in ARPAC. We see a higher increase in engagement. We see higher activation. So it, not only adds additional ARPAC, it brings a lot of synergies to the platform as a whole. In terms of working capital loans, we are just beginning to test that product. It's tiny in our base. It is something that we are ramping up slowly. And we're testing a number of different secured and unsecured products for the small business, but we haven't really rolled out anything big yet.

Guilherme Marques do Lago

The only thing, Thiago, that I would add to that is that similarly to the profit pool that we see in consumers, the profit pool that we estimate to exist in SME is still 65% to 70% driven by credit. And within credit, we started with credit card for SMEs. The credit card business is performing extremely well. We are super encouraged by the early results, and then we are gradually expanding into working capital.
What we expect, however, in SME is that differently, for example, from the public payroll on market, is not necessarily a market in which our growth will hinge on someone else losing market share. We think there's a tremendous opportunity to increase the size of the pie within the credit penetration in the Brazilian SME space. It still has very low penetration and we think we can expand the market quite strongly.

Jorg Friedemann

And our next question comes from the line of Geoffrey Elliott from Autonomous.

Geoffrey Elliott

Can you hear me? Sorry, I think I had to click a couple of times to unmute. Can you hear me now?

Jorg Friedemann

Yes, we can hear you now.

Geoffrey Elliott

Great. Share-based compensation was quite a bit higher this quarter than it has been. Can you just remind us of the dynamics that is the share price a driver? Is it about grant? What's going on? What drives that? And how should we think about it on a normalized level?

Guilherme Marques do Lago

Geoff, this is Lago. Thanks for the question. Yes, we had an increase in share-based compensation. And, I think, it is largely the result of 3 compounding effects. I think number one is there's a general head count growth in the company. Number two is the result of more aggressive performance recognition than we did in the first quarter of 2024, compared to the first quarter of 2023. And number three, the share appreciation, which negatively impacts our social tax contributions, primarily in Brazil, which can account for up to 36% of the grants.
So as you will see our explanatory notes for the financial statements, you will note the increase in share-based compensation, but also the corresponding increase in shared taxes and social contribution taxes, which are accounted together with share-based compensation. Now one of the things, Geoff, that we take very seriously is the net and gross dilution that we apply to our shareholders. And if you take a look at our gross and net burn rates, we have been operating below 100 basis points. In fact, over the past 2 years, we have been operating below 60 basis points.
And we believe, the number one, that we are in the bottom quartile of the industry in terms of companies that apply the lowest levels of dilution to our shareholders. And number two, as we increase in size and value, we do expect operating leverage to continue to play its part here, so we expect that this number will actually go down over time.

Geoffrey Elliott

And in terms of what to think about as a normalized figure there. I guess we would want to take out the share price appreciation. It's probably not going to be up 40% every quarter. So what can you point us to, to get to a more normal figure?

Guilherme Marques do Lago

So we don't provide guidance on that. But if you take a look at explanatory note #10 of our financial statements, you will note -- and you will see how much of that increase came from share price appreciation they are more or less. So you can exclude the number from the total share-based compensation. We do, however, pay much closer attention, Geoff, to our net and gross burn rates. And we think, on that note, one should easily expect that this will be meaningfully below 100 basis points per year.

Jorg Friedemann

Our next question comes from the line of Gustavo Schroden from Bradesco BBI.

Gustavo Schroden

I'd like to explore a little bit the NIM. Indeed, that was a very impressive NIM in the quarter. But I would like to understand the trends and the moving parts here. Because if one side, we have an increase in the cost of funding from 80% to 84%, on the other hand, if we analyze specifically the personal loans average interest rates declined from 6.4% to 6.2%. So I am assuming here that the difference here or the positive is coming from the other products such as the credit card installments, revolvings -- revolving and also some trading gains or other products.
So my question is, could you give us more color on these other products if you are raising interest rates in these other products to offset this, let's say, kind of a pressure if we compare the cost of funding versus the personal loans? I'm asking this because I can see that the secured loans are gaining share in your portfolio. So any color on that would be great.

Guilherme Marques do Lago

Gustavo, this is Lago. Thanks so much for your question. I think you are referring to Slide #17 in our earnings presentation. And yes, we have experienced what we believe to be a relatively strong expansion in net interest margin. Over the past 4 quarters, it went from about 15% to 19.5%. And it is largely the result of 2 opposing forces. I think on one aspect, on one side, you do have the optimization of the balance sheet in Brazil. As you see the expansion of our loan-to-deposit ratio going from 30% to 35%, then to 40%, you should generally expect to see net interest margins going up.
And even though you've mentioned that secured personal loans have lower yield levels than unsecured and also lower interest levels than credit cards, they do have materially higher yields than the treasury bonds in which we deploy most of our excess cash. So as we shift part of our treasury in treasuries to interest-earning assets of consumer finance, you should expect to see net interest margins expanding in Brazil.
The offsetting force to which I alluded before is our operations in Mexico and Colombia, in which we are paying, as of today, deposit rates that are slightly higher than the interbank deposit rates in those countries, which bring the net interest margins down on one side. So I think going forward, those 2 offsetting forces will play out, we do expect to see net interest margin to continue to expand on average in the coming quarters.

Gustavo Schroden

That's very clear, Lago. Just a follow-up here. What is the -- let's say, the level of loan-to-deposit ratio we should use in our model to -- in my opinion, according to your answer, that should be a good proxy or a good variable to forecast and trying to get the best NIM in the future. So if you could share with us what is the good level of loan-to-deposit ratio would be great as well.

Guilherme Marques do Lago

Yes. So, I mean, a good reference more than a guidance is the loan-to-deposit ratio of the large retail in common banks in Latin America is between 100% to 110%. I don't expect that we will get to a loan-to-deposit ratio anywhere close to those levels, but it will be materially higher than the 40% that we presented in the last quarter.

Jorg Friedemann

And our next question comes from the line of Jorge Kuri of Morgan Stanley.

Jorge Kuri

Congrats on the numbers. I wanted to see if you could maybe double-click on your loan-to-customer growth during the quarter. It was really impressive, 21% quarter-on-quarter on the total balance. You also disclosed your originations going from BRL 1 billion to BRL 1.7 billion. How much of that is attributed to the early success of your payroll loans? How much of that is FGTS continue to develop the personal loans business?
Anything that you can help us understand what is the look and feel of this very big uptick in personal loans would be -- in loan to customers, sorry, would be very helpful. And again, I think the market's very excited about the prospects for payroll loans. So to what extent that is included here? And what can you tell us about this whole growth?

Guilherme Marques do Lago

Jorge, Thanks for the question. This is Lago. I think we are very pleased with the evolution of the total portfolio growth that we have presented. I would point you to Slide 36 of our earnings presentation, in which we provide more details on the breakdown between personal loans and credit card growth. And one of the things that you will note is that irrespective of the seasonality, we have been posting fairly robust growth in our credit card book.
In fact, by the end of the first quarter of 2024, we estimate that our market share in cards, in general, has reached about 15%, 1-5, which would place Nubank as the second credit card issuer in the country, and we continue to acquire market share quarter after quarter. Now notwithstanding the robust growth in credit cards, personal loans is actually outpacing credit cards, and that has happened over the past 5 quarters in a row. And you will note that in the first quarter of 2024, personal loans grew by 25% on an FX-neutral basis. Credit card grew by 8%.
Now to your question, within personal loans, I would then refer you to -- let me take a look here to Slide 15, in which you can see the evolution of the originations of personal loans. You will see that over the past 4 quarters, it increased from BRL 6 billion per quarter to more than BRL 12 billion. So we almost doubled the originations. You see that still, the primary driver of this absolute growth is with unsecured personal loans. The eligibility of which continues to expand across our customer base.
If you take a look at the total personal loan -- unsecured personal loan pie in Brazil, which accounts for the second or third largest profit pools in the country, our customers alone, as of the end of the fourth quarter, accounted for about 43% of the entire loan book in Brazil. And we still have no less than 8% market share there, so we have plenty of room to grow.
Now at the beginning of the second half of 2023, we expanded in secured personal loans, which encapsulates consignado or public payroll loans, FGTS and investment-backed loans. Public payroll loans and FGTS account for about 90% of our total originations, with investment-backed loans accounting for 10%. We expect that the originations of secured personal loans will continue to outpace the originations of unsecured personal loans as we increase the collateral agreements that we have as of today.
So today, we offer public payroll loans, Jorge, primarily to INSS and SIAPE, which are now federal public servants and pensioners and retirees, which account broadly for 50% of the target market of secured personal loan in Brazil. We will be increasing our scope to add armed forces in many states and municipalities, and we hope to reach about 75% of the target market by the end of 2024.

David Velez-Osomo

And just to finalize that, Jorge, I think one, perhaps, easy way to understand really the significant opportunity we continue to have ahead is we have more or less 60% of the Brazilian adult population as a customer. That 60% owns something like 40% to 50% of the entire credit pool in the country. And if you just look, on an average basis, across the lines, we probably have something like 10% market share.
So we could double, triple, quadruple the size of our existing credit portfolio. And the bottleneck to growth is on the unsecured side, our own willingness to grow, our own willingness to take risk. And thus, in certain areas, we go very slowly, and we test our way into acceleration. And on the secured side, our bottleneck is signing up a bunch of contracts with a number of different entities.
We have been signing up all those contracts. Whenever we go to the entities and we say we are going to be offering products for your associates that are 30% to 40% lower interest than everybody else, that is a very good value proposition for them. And so we haven't seen a lot of real resistance in signing up the contracts with us.
There is some interconnection of systems. We have to integrate with a number of older systems, so that takes some time, and that's going to be taking some time over to next year. But so far, we feel very good about our ability to grow in the pool of addressable secured portfolio in the country.

Jorge Kuri

If I may ask a follow-up. I'm looking at your Slide 19, where you have the last 5 quarters of gross profit margin. Given the particularities of what's happening with your asset mix and the deposit mix with Mexico, would it still be fair to assume a seasonal behavior like we see here in 2023, where, sequentially, every quarter was up in terms of gross profit margin in 2023? Would that be applicable for this year? Or the dynamics are going to be different because of these 2 items that I mentioned?

Guilherme Marques do Lago

Jorge, I think it will largely depend on the velocity with which we grow deposits in both Mexico and Colombia, by and large. If it was only for Brazil, one would expect that gross profit margins would continue to expand sequentially throughout the quarters, especially because the first quarter is usually a low seasonal quarter for us.
But the expansion of gross profit margins in Brazil is partially or fully offset by headwinds coming from Mexico and Colombia. So those 2 things will be playing out. It depends on the speed with which they play that we will see this resulting in our gross profit margin. I still believe that throughout 2024, one would expect to see gross profit margins for the full year very much in line with the gross profit margin that we had for the third quarter of 2023, so around 42%, 43%.

Jorg Friedemann

And our next question comes from the line of Eduardo Rosman from BTG Pactual.

Eduardo Rosman

I have a question here. I want to delve deeper into your strategy of deposits in Mexico. You're having massive success, but that's naturally coming at a cost, right? So when we look to incumbents, we see that they pay very little, as a percentage of the reference rate. So what's the goal there in terms of remuneration, short and medium term? Goal is to reduce the remuneration? Or eventually pressure competition to move higher? And also, if you can also give an update as well on your recent partnership for cash-in and cash-out and the challenge naturally to grow deposits in the low income there.

David Velez-Osomo

Eduardo, here's David. So listen, Mexico is a really attractive market for a number of different reasons. One of the interesting reasons that has become much more visible to us recently is that, differently from Brazil, the deposits as a product is the largest source of profit for the incumbent banks. So when you look at the average yield that banks are paying consumers, it's something like 3% to 4% a year when you have an interest rate -- a sovereign interest rate in the 12%, 13% plus. So this is a bit of an abnormality in a regular banking market, because banks are effectively making significant profits without really taking any risk.
When you look at Brazil, you see a market where -- that is driven very much by taking credit risk, which generally is what you would expect in competitive markets. That's not the case in Mexico. And when you look at the level of interest rates in products, they are still very high. So in a product when we make -- we look at our unit economics, even offering at very high yield, we're still making positive unit economics given the structure of the market.
Now given the fact of how these profits exist in the system, we think this is a really interesting disruption opportunity for the entire Mexican system, because if most of your profits are coming from deposits, frankly, the barrier to entry is not that high. Yes, probably in the past, you needed branches. Now you don't. And yes, brand is important because consumers won't leave their life savings in a brand that they don't trust. But the reality is if you have a good brand and you have a very good product, you will take those deposits away.
And, I think, the past 6 to 9 months and the pace of growth that we're showing with this yield is showing very significant growth above our expectations and much higher than our fintechs that are paying even higher yields than we are. So we're, not only necessarily just competing by higher yields. You are already being able to see that we built a very solid and trusted brand in Mexico and this has been a big source of deposits.
Now all being said, I think in the long term, we will also rationalize the cost that we are expecting. We tend to make this decision based on value proposition. Our goal is to have the very best deposit value proposition in the country. That is a function of yield and features. Initially, our features were not that big, which meant we had to rely a lot on yield, and that's what we're doing right now. But very soon, our features have been growing. And by the end of the year, it will be a very different product.
And you mentioned cash-in, cash-out, that was a significant bottleneck that we had a few months ago. We are solving that as we speak. So as we increase the level of features, as we increase the value proposition, as we strengthen the brand, we expect to be able to decrease yield while maintaining the best value proposition. We think that incumbent banks are going to have to increase the yield that they're offering consumers if they want to keep a lot of these consumers.
Ultimately, in this new world, there's just not that many barriers of entry and you just cannot keep your consumers trapped. They will go to whoever gives them the best option. And so we think we are on path to building that product in that category that way.

Guilherme Marques do Lago

Rosman, if I may add one thing. What we have been seeing in Mexico, as we have seen in Brazil in the past, is that as we attract deposits from customers in the country, we are also benefiting from very relevant second order impacts that allows us to increase our brand awareness. It allows us to increase credit card applications. Our credit card applications have more than doubled in Mexico since we repriced our deposit products. It allows us to acquire data to do better credit underwriting and customer segmentation. It gives us positive credit selection.
So there is a tremendous amount of second order impact that the deposit flows are bringing to our flywheel that are not necessarily captured, only in the absolute nominal amounts of deposits that we see coming in.

Jorg Friedemann

And our next question comes from Yuri Fernandes at JPMorgan.

Yuri Rocha Fernandes

I have just one on renegotiated loans. I see you don't have the slide anymore on your presentation. So if you may just provide some color on how the numbers are tracking in the first quarter, how this compares to the 9.6% that you had in the 4Q? So just trying to get some color on renegotiated loan strength.

Guilherme Marques do Lago

Yuri, this is Lago. Thanks for the question. So renegotiations loans still account for about 10% of our portfolio. It has not changed materially since we last presented this. We do expect that we will be disclosing our renegotiation rates on an annual basis at the -- whenever we disclose our fourth quarter results. In addition to that, you can see some levels of renegotiations in the filings that we present to the local regulators, especially in Brazil that we do on a 6-month basis.
Going forward, however, as we know, change and reposition, the mix of our credit products in Brazil primarily, both between personal loans and credit; cards and within personal loans, between secured and unsecured, those should directly affect the rates of negotiations. But there has been no material change since we last presented this in the last quarter.

Yuri Rocha Fernandes

Super clear, Lago. And just for a better understanding on new NPL formation and asset quality trends, you mentioned renegotiations are not there. Is there any other factor that is helping your new NPL formation? Or is this really a mostly stable quarter for new NPL formation for the company?

Guilherme Marques do Lago

So, I think, there's no material nonrecurring item that would be distorting our NPL and Stage 3 formation. So, I think, they are pretty much BAU.

Jorg Friedemann

And our next question comes from the line of Pedro Leduc of Itaú.

Pedro Leduc

I'm looking at NII post cost of risk and it rose mid-single digits Q-on-Q, if I'm not wrong. I understand your provisions ate up a lot of the NII growth. I'm really curious about this combo, this net basis of mid-single-digit growth. It's historically below what you've been growing at and I don't see that much of a difference in your loan book growth.
So -- I have some hypothesis, maybe the loan book that we see at the end of the quarter doesn't reflect the average of what it was last quarter, so it didn't generate that much NII or that incurred losses are being different than the expected loss that you had to catch up. Really curious on how you piece together this NII post cost of risk being basically flat and how we should think about it going forward.

Youssef Lahrech

Pedro, this is Youssef. Thanks for the question. So I think you're referring to risk-adjusted NIM on Page 26, where you can see the evolution over time. And again, as a reminder, if you compare quarter-on-quarter, you have to bear in mind that Q4 2023 was impacted by a suppression of the CLA because of higher recoveries than normal and that was driven by Desenrola and some of the collections programs we put in place in Brazil to take advantage of that as well.
So in reality, the 10.2% in Q4 was inflated. It would have been closer to what we've experienced this quarter at 9.5%. So -- and in reality, if you take a longer-term horizon view year-on-year, we've seen a pretty sizable expansion of the risk-adjusted NIM by about 320 basis points or so. If you look at cost-of-risk around -- along the same basis, it went from 8.7% to 10%, so about 130 basis points. So you see quite a bit more expansion in the margin, 2.5x expansion in the margin compared to the expansion in cost of risk.

Guilherme Marques do Lago

Pedro, the only thing I would add to what Youssef mentioned, if I may, is that if you take a look at the originations of -- and the mix of new credits that we have added in the first quarter of 2024, I would draw your attention to Page #15. You will see that unsecured personal loans in the fourth quarter of 2023 grew by about BRL 400 million. And it grew by about BRL 1.6 billion from the fourth quarter of 2023 to the first quarter of 2024. So there was a material growth in credit books in unsecured personal loans, which actually draw more CLA than credit cards. So the mix of growth also plays a role on how risk-adjusted net interest margins should be seen. But I'm not sure if we have fully addressed your question, Pedro.

Pedro Leduc

Yes. I'm almost a little more confused, because I thought 4Q, you had a netting [effect] and provisions. I thought it was net zero if I was comparing it sequentially. And I do understand your reasoning there on the mix evolution. But as I did expect it to come a little bit more with NII, expecting it originated more towards the end of the quarter.

Guilherme Marques do Lago

No. I mean, we can certainly follow up with you in more details on the timing of the originations throughout the quarter. But I don't think there was any one-off originations that happened, let's say, in March that was materially higher than what happened in January and February, so relatively levels of originations.

Jorg Friedemann

And our next question comes from the line of Mario Pierry from Bank of America.

Mario Lucio S Pierry

I wanted to stay on asset quality. When we look at your NPLs, they are at the highest level in the series, right? The NPL over 90 days is 6.3%. When I look at your loan Stage 3 formation at 3.7%, also historical high. You talked about, on your release, that the increase in expected losses -- or you had an increase in the expected losses because you're increasing the risk profile of the newer cohorts.
So what we're seeing in Nubank is very different than what we're seeing at the other banks in the system in Brazil, where the banks really became very cautious in lending and we're seeing our NPLs improving and asset quality improving.
So I wanted to pick your brain as how can you be so confident, right, in continuing to take on more risk? Why do you think that the consumer in Brazil is in good shape. You already showed, right, that the interest portion of the credit card is at 26%, well above the industry.
And so the ability of the consumer to continue to take on more credit and more risk, clearly, right, you are pricing that. You're increasing your return on your loans, but eventually, it gets to a level that is too high. So just trying to pick your brain here. It seems like you're moving down into a riskier segment of the population, while everyone else is doing the opposite. So that's my question.

Youssef Lahrech

Yes. Youssef, here. Thanks so much for the question. So let me maybe address or remind us a little bit about how we think about credit underwriting, if you'll allow me, and then I'll address specifically the latest trends. So when we underwrite credit, our objective is not to minimize NPLs.
Rather, our objective is to maximize the NPV of that credit brand to maximize the NPV of that customer relationship subject to resilience constraints, right? So specifically, we want to ensure that every credit grant that we make is NPV positive, even in the event of a downturn. So we typically don't take a position with respect to timing, the point of the cycle at which we're at. We're fairly agnostic to that.
We want every origination we make to perform in good and bad times. So when we see opportunities to expand credit and taking a little bit more risk, especially with products and features that customers love and create a lot of value. For them, like, we see with some of the financing products we've introduced, like fixed financing on the credit card or unsecured loans, we're not shy about taking that risk, but we always do it with very rigorous testing.
Sometimes testing for months and several quarters before we roll out and very rigorous monitoring of the risk and return that we get as a result. And we've been very happy with the results of those expansions, as I mentioned earlier, be they in personal loans, secured and unsecured or in credit cards, as you can see in the expansion of our interesting-earning portfolio that Lago talked about.
One way perhaps to think about the dynamic of -- the dynamic in our credit book is looking at the data we showed on Page 25 of the earnings presentation, which shows you NPLs as a ratio of interest-earning balances. You see there that we've grown interest-earning portfolio balances faster than we've grown NPLs. And thus, that's a simple way to kind of validate that this is accretive to return in NPV.
So again, this is not a result of us kind of taking a particular position on where we are at the cycle. It's rather us testing over months and quarters and years, new products, new features, observing the returns and then deciding to roll out when we see really good and resilient returns on that.

David Velez-Osomo

One point I would add, just to close on Youssef's explanation is the majority of the additional products, the financing products that we've been launching, that we've been growing are very short-term duration in nature. We're talking about 30, 60 days type of loans.
So this tends to be a really high information-rich type of product that allows us to react very quickly to any signs that we might see, things that are not playing out as we expect. Again, we're making an underwriting decision based on our view of an NPV model, based on a lot of testing, based a lot of foundational testing that we're doing. And the ability to do this type of short-term -- short-duration products just allow us to increase the financing portfolio that we have while maintaining significant control on the risk of the portfolio.

Mario Lucio S Pierry

Okay. Let me ask a follow-up here. When I look at your credit cards outstanding in Brazil, it went up by about 200,000 from $37.5 million to $37.7 million. Even though your active clients in Brazil grew by 3.6 million. So this is the slowest pace in the increase of number of cards, right?
The average -- you're growing about 1.8 million credit cards in Brazil in 2023 per quarter. Now you did 200,000. What does this mean? Does it mean, like, you are being more conservative? Or you reached a percentage of your client base that it's -- they don't have the capacity to take on a new credit card?

Guilherme Marques do Lago

Mario, one thing that I would point out, and I'd certainly let my other colleagues chime in is that, in Brazil, as we start to approach now 55%, 60%, 65% of the adult population, it's inevitable that the marginal growth will not necessarily come from adding more customers or more credit cards to the existing customer base.
We still have a lot to go there, but it's only natural that at some point in time, the growth in number of customers of the number of cards will diminish. But what we still have plenty of room ahead is what you can see on Page 34 of the earnings presentation. And you can see the evolution of the purchase volume and the evolution of ARPAC as the customers mature.
So even at the customers that we have on-boarded 24 months ago, they are tripling their purchase volume as they mature their usage with us. So what we will naturally see in Brazil is that a natural kind of a flattening of the curve of number of customers and credit card customers, but the continuous evolution of the maturation of purchase volumes in ARPAC.
And then conversely, Mexico and Colombia are in the very early days of the expansion of a number of customers and number of cards. So they are in a different point of the escrow cycle there.

Jorg Friedemann

And our next question comes from the line of Brian Flores of Citi.

Brian Flores

I wanted to make a follow-up on Mexico. We talked on the liability side, and, I think, that is ramping up very well. Wanted to ask you on the asset side, right? Because we have seen, as Lago mentioned, some room for optimization with the low LDR so far. So I wanted to pick your brain on what key differences have you found in client behavior, infrastructure? And also, how has your strategy affected this, right? And if you think the speed is going according to the plan? Or do you think it's maybe a bit slower? Or a bit ahead?

David Velez-Osomo

Thanks for the question. So we've said a lot of times in the past that we tend to go into a new market, underwriting very conservative, a very conservative approach. And the growth curve that you will see from us in a lot of the unsecured products really now is periods of acceleration, periods of pause, even periods of tactical detractions, accelerations, pauses. You saw that if you look at our growth rate in unsecured lending and personal loans maybe 12 to 8 months ago. We had a bit of a pause and we accelerated again. I think Mexico is following a very similar path. We launched slowly, we accelerated. We did a lot of foundational testing.
That's, by the way, the reason why delinquency in the country was much higher. We were just testing a lot. This really means giving a number of different lines and credit cards to consumers where we don't have really any data. A lot of these is credit losses. But in reality, it's CapEx. It's effectively R&D dollars into building our own models.
And where you've seen Mexico, maybe over the past 6 months, was after a period of acceleration with deaccelerated growth. We went into a period of slowing down a bit our growth, partly was to continue working on new generations of models that ingested new data sources, partly was also because we wanted to see how funding was going to come on.
As you, obviously know, we cannot just accelerate too much if we don't have funding resolved. So getting NuConta right in Mexico for us was the number one strategic imperative, because if we don't have that part of the balance sheet, we don't really have a business.
So with the decelerated a bit to continue iterating on products. We launched NuConta. NuConta has been very successful. We've also -- if you look at some of the numbers that we disclosed, the regulatory reports or delinquency in Mexico has been coming down a lot very fast. We're operating with much lower delinquency levels.
And this is now driving a low acceleration, again, into credit cards in Mexico and new accounts. You see that, also, the number of new customers in Mexico has accelerated over the last quarter. So I'll give you all this context to effectively say we're now on path of accelerating again on Mexico. We have the funding.
We're very comfortable with some of the data sources, our ability to do underwriting based on our own methodology, on our own consumer behavior. And we'll continue to operate a bit like that. As we see opportunities, we accelerate. We see things that worry us a bit, we pause a bit. And that tends to be the path that we tend to take in these new markets.

Guilherme Marques do Lago

The only thing, Brian, I would add is that if you take a look at the first quarter results of our operations in Mexico, the one that we filed with the local regulators, you will note that we're already growing our book in Mexico at about 7%, 8% on a quarter-over-quarter basis. We expect this growth rate, as David mentioned, will pick up in the coming quarters.

Brian Flores

Perfect. And if I may follow up just very quickly, do you have any updates on the banking license? Do you think this is critical to really ramp up growth as you mentioned?

David Velez-Osomo

Yes, sure. So it is not critical to ramp up growth. We can continue ramping growth with the SOFIPO license that we have. We are getting the deposits that we need, and that's the critical part. I think the banking license is really critical for the long term of Mexico. There are certain bottlenecks in the SOFIPO license that eventually will become real issues for our products. One specific example is deposit insurance. SOFIPO only gives us a deposit insurance of something like $18,000 to $19,000 and bank license gives deposit insurance all the way to $180,000.
So for Mexican high income consumers, it will be critical to have a banking license. That's not our core target today. It also -- a banking license will also expand the possibilities of cash-in, cash-out with certain banking correspondents. And so thinking ahead of where the business will be in 5 years from now, we definitely need the banking license. And that's why we already, last year, entered with the process of the banking license. The process is going well with -- I think the regulators are doing all of their work around the due diligence.
We've been very active working the regulator, answering all the questions that they've received. And so far, it's going according to expectations. It's not necessarily an easy process. It's not a fast process, but we're taking the process very seriously. And so far, we've heard very goodwill from the regulator in enabling new players to get banking licenses to bring much more competition into the banking space in Mexico.

Jorg Friedemann

And our final question comes from Neha Agarwala from HSBC.

Neha Agarwala

I wanted to zoom in on Mario's previous question in terms of asset quality. Originations, especially in the personal loans, was extremely strong this quarter, but early delinquencies have inched up. I understand part of that is seasonality. But given the rate outlook and the softening of economic activity, would you be more concerned or more cautious in the coming quarters and try to step back a bit in terms of originations? Or should we see continued these level of originations for personal loans? Or an acceleration?

Neha, this is Youssef. Thanks so much for the question. So you are right in pointing out that the NPL movement in the quarter from Q4 to Q1, particularly NPL 15 to 90, was largely the result of seasonality that we've experienced, so 90 bps increase typically. The increase in Q4 to Q1 is 80 bps, so more or less within the seasonal expectations and perhaps to be super precise a little bit, coming from credit expansion, as we mentioned multiple times in both personal loans and secured personal loans and the credit card earning interest portfolio as well.
And as I mentioned before, we tend to be fairly agnostic to the point in the cycle at which we're at because when we originate credit, when we underwrite credit, we always make sure that, that credit performs and is NPV positive under good times and bad times, right? So we stress the risk expectations in our NPV model, which ensures that our cohorts, on aggregate, can withstand a doubling of risk and still be NPV positive. So we're very comfortable with the level of resilience with which we operate that way.
With that all said, as I've mentioned in past quarters and this quarter again, our expectation is that there are going to continue to be really good opportunities for us to expand our credit portfolio across the board, right? We see updates to expand in secured lending as Lago and David have discussed. We see opportunities in unsecured personal loans to increase eligibility to -- of customers and also in credit cards with the continued growth of IEPs and the continued rollout of new products and features on the financing front.
So our expectation is definitely that there will continue to be opportunities to extend. And typically, as we've done in the past, in Brazil and Mexico and other markets, when we see results that are a little bit different than what we expect on the downside, we will take the appropriate action to slow down if that's what the situation calls for.
