(Reuters) -Oil prices rose on Monday, shaking off weaker demand expectations as supply concerns mount heading into the winter.

Brent crude futures rose $1.51, or 1.6%, to $94.35 a barrel by 12:42 p.m. EDT (1642 GMT). U.S. West Texas Intermediate crude was up $1.28, or 1.5%, at $88.07.

U.S. emergency oil stocks fell 8.4 million barrels to 434.1 million barrels in the week ended Sept. 9, its lowest since October 1984, according to data released Monday by the U.S. Department of Energy (DOE).

U.S. President Joe Biden in March set a plan to release 1 million barrels per day over six months from the Strategic Petroleum Reserve to tackle high U.S. fuel prices, which have contributed to soaring inflation.

The Biden administration is weighing the need for further SPR releases after the current program ends in October, Energy Secretary Jennifer Granholm told Reuters last week.

Global oil supply is expected to tighten further when a European Union embargo on Russian oil takes effect on Dec. 5.

The G7 will implement a price cap on Russian oil to limit the country’s oil export revenue, seeking to punish Moscow over the invasion of Ukraine, while taking measures to ensure that oil could still flow to emerging nations.

The U.S. Treasury, however, warned that the cap could send oil and U.S. gasoline prices even higher this winter. [nL1N30I0BQ

France, Britain and Germany also on Saturday said they had “serious doubts” about Iran’s intentions to revive a nuclear deal. Failure to revive the 2015 deal would keep Iranian oil off the market and keep global supply tight.

In more bearish news for markets, China’s oil demand could contract for the first time in two decades this year as Beijing’s zero-COVID policy keeps people at home during holidays and reduces fuel consumption.

“The lingering presence of headwinds from China’s renewed virus restrictions and further moderation in global economic activities could still draw some reservations over a more sustained upside,” said Jun Rong Yeap, market strategist at IG.

The European Central Bank and U.S. Federal Reserve, meanwhile, are prepared to increase interest rates further to tackle inflation, which could strengthen the U.S. currency and make dollar-denominated oil more expensive for investors.

“Although a comparatively stout U.S. economy has limited oil demand weakness in the U.S., apparent demand for both gasoline and the distillates continue to slip by around 8% to 9 % on a 4-week average basis compared to a year ago,” said Jim Ritterbusch, president of Ritterbusch and Associates in Galena, Illinois.
