Oil falls on oversupply concerns but tighter fuel markets limit drop

Oil prices fell on Wednesday due to higher crude inventories in the U.S., reinforcing oversupply concerns, but falls were limited by a tighter fuel market as a result of attacks against Russia's oil infrastructure.

Brent crude futures fell 71 cents, or 1%, to $64.18 a barrel by 1111 GMT, after gaining 1.1% the previous session.

U.S. West Texas Intermediate crude futures fell 63 cents, or 1%, to $60.11 a barrel, after rising 1.4% on Tuesday.

U.S. crude stocks rose by 4.45 million barrels in the week ended November 14, while gasoline inventories climbed by 1.55 million barrels and distillate inventories increased by 577,000 barrels, market sources said late on Tuesday, citing American Petroleum Institute figures.

"Overall, the report was relatively bearish," said ING commodities strategists, though they cautioned: "Market participants appear more concerned about supply risks than the odds of a surplus going forward."

Prices rose on Tuesday because of a tighter diesel market on the back of lower Russian exports, PVM analyst John Evans said.

U.S. sanctions on Rosneft and Lukoil set a November 21 deadline for companies to unwind their dealings with the major Russian producers.

On Monday, the U.S. Treasury said the sanctions, already squeezing Russia's oil revenue, are expected to curb its export volumes. Crude buyers in China and India have already started switching to alternative suppliers.

Concerns about Russian supply are being weighed against analysts' forecasts that oil output is in excess of current demand, which has put pressure on prices.

After Ukrainian attacks on Russian energy and port infrastructure, profit margins on diesel fuel surged in Europe, reaching their highest on Tuesday since September 2023, amid an increase in refinery margins globally.

Official U.S. government inventory data will be released later on Wednesday. Eight analysts polled by Reuters estimated that crude inventories were likely to have fallen by an average of about 600,000 barrels in the week to November 14.
