(Bloomberg) -- Oil slumped the most in two weeks alongside a broader market rout as a resurgent virus in some of the world’s top oil importers highlighted the uneven road to recovery.West Texas Intermediate fell 1.5% to the lowest in a week as S&P 500 Index headed for its first back-to-back decline since late March. The rampant virus spread in countries such as India is casting a shadow on optimism over the global economic rebound. Annual crude imports in the Asian country fell for the first fiscal year since the late 1990s with refiners cutting run-rates.“We’ve seen risk appetite reverse,” said Bart Melek, head of commodity strategy at TD Securities. “Variants are wreaking havoc on some economies, and it’s uncertain how the whole demand picture will evolve.”The Bloomberg Dollar Spot Index was set to snap a six-day streak of declines, reducing the appeal of commodities priced in the currency.Still, the market is a far cry from where it was a year ago today, when an unprecedented crisis saw U.S. benchmark crude futures closing at negative $37.63 a barrel. The historic plunge came as lockdowns savaged demand and key producers Saudi Arabia and Russia flooded the market in a price war. A restoration of OPEC+ unity marked by deep supply cuts, as well as vaccine distribution around the world, have helped prices to climb back.Despite near-term headwinds, there are also points of optimism for an upcoming surge in global oil consumption. Driving is soaring in the U.K. as more than 60% of its population over 18 has received a first vaccine dose. Vitol Group, the world’s biggest independent oil trader, expects demand to come roaring back, echoing optimistic views from OPEC and the International Energy Agency.“Once we get into May, we should start to see the next leg down in the virus, and that will be a tailwind for oil,” said Jay Hatfield, CEO at InfraCap in New York. “Until we get there, prices are likely to be range-bound.”In options markets, growing confidence is being reflected in the so-called put skew. The premium that traders are willing to pay on bearish put options versus call options for global benchmark Brent futures narrowed to the smallest in a month on Tuesday.Along with concerns around the lagging demand recovery in some regions, signs of progress being made in talks on the revival of a 2015 nuclear deal raises the prospect of additional Iranian supply further out. A return to the deal could include lifting U.S. sanctions on the Persian Gulf country’s oil exports.Meanwhile, U.S. oil stockpiles are expected to have fallen last week, which would extend the streak of drawdowns to four weeks, according to a Bloomberg survey. The American Petroleum Institute will report its figures later Tuesday ahead of U.S. government data.In physical markets, front-month WTI’s widening discount to Brent is luring foreign demand for U.S. sour crudes. Southern Green Canyon is trading at the smallest discount to Nymex crude futures in two months, while other sours like Mars Blend and Poseidon have also strengthened recently. WTI is trading at a nearly $4-a-barrel premium to Brent compared to $3 at the end of March.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.
