(Bloomberg) -- Prices paid to U.S. producers rose in April by more than forecast, adding to signs of a growing wave of inflationary pressure that’s extending to American consumers.The producer price index for final demand increased 0.6% from the prior month after a 1% gain in March, according to data from the Labor Department Thursday. Excluding volatile food and energy components, the so-called core PPI advanced 0.7%.A Bloomberg survey of economists called for a 0.3% monthly gain in the overall measure and a 0.4% rise in the core figure. The April advance was broad across both goods and services.As production costs continue to climb, a report Wednesday showed consumer prices are following suit, stoking the flames of an already heated debate about the path and durability of inflation that the Federal Reserve views as temporary.The PPI tracks changes in production costs, and supply bottlenecks and shortages tied to the pandemic recovery have caused commodity prices to soar. At the same time, labor costs have begun picking up. Together, the increases represent a threat to profit margins unless companies pass along the higher costs and boost productivity.Fed officials have said price pressures from pent-up demand and bottlenecks will likely prove temporary, but many others expect the pickup in inflation to prove more lasting.“There is more inflation coming,” Luca Zaramella, chief financial officer at Mondelez International Inc., said on the food and beverage maker’s April 27 earnings call. “The higher inflation will require some additional pricing and some additional productivities to offset the impact.”Consumer InflationWednesday’s data -- which showed the strongest monthly gain in the overall consumer price index since 2009 -- suggest companies are passing along at least some of the input-price inflation. The report also showed record monthly price surges in airfares and hotel stays, reflecting the impact from a broader reopening of the economy.The annual advance in the overall PPI accelerated to a 6.2% gain, a figure biased higher by the fact that it was compared to the very low reading seen in April 2020. The increase was the largest in data back to 2010.A separate Labor Department report Thursday showed applications for regular state unemployment benefits declined for a second week, to a fresh pandemic low. A slew of states have recently announced intentions to stop federal pandemic relief programs prior to their expiry in September.Producer prices excluding food, energy, and trade services -- a measure often preferred by economists because it strips out the most volatile components -- jumped 0.7% from the prior month and increased 4.6% from a year earlier.While the advance was broad-based across goods and services, about two-thirds of the monthly gain can be attributed to the 0.6% gain in prices for final demand services, the Labor Department said. The indexes for portfolio management, airline passenger services, food retailing, physician care and building materials and supply retailing all moved higher.The advance in the goods index reflected an 18.4% jump in prices received for steel mill products as well as increases in the prices for a variety of meat, residential natural gas, plastic resins and materials, and dairy products.Michael Hsu, chief executive officer at consumer-product maker Kimberly-Clark Corp., said in April that the maker of Scott toilet paper and Huggies diapers is “moving rapidly especially with selling price increases to offset commodity headwinds.”For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.
