Oil prices rose by over $2 on Nov. 30 on signs of tighter supply, a weaker dollar and optimism over a Chinese demand recovery.

Capping gains, the OPEC+ decision to hold its Dec. 4 meeting virtually signals little likelihood of a policy change, a source with direct knowledge of the matter told Reuters on Nov. 30.

Brent crude futures rose $2.33, or 2.81% to $85.36/bbl by 12:33 p.m. EDT (1733 GMT). WTI crude futures in the U.S. climbed $2.13, or 2.7%, to $80.33.

Support followed expectations of tighter crude supply.

U.S. crude oil stocks plunged by nearly 13 million barrels, the most since 2019, in the week ended Nov. 25, according to the Energy Information Administration (EIA).

But heating oil demand fell for the second consecutive weak heading into winter, curbing price support.

“Running all that crude oil through the refinery, you’re going to process a lot of distillate...there is some reason for concern here,” said Bob Yawger, director of energy futures at Mizuho.

Likewise, U.S. oil output climbed 2.4% to 12.27 million bbl/d in September, government figures showed on Nov. 30, the highest since the onset of the COVID-19 pandemic.

The International Energy Agency (IEA) expects Russian crude production to be curtailed by some 2 million bbl/d of oil by the end of the first quarter next year, its chief Fatih Birol told Reuters on Nov. 29.

Russia would not supply oil to countries imposing a price cap, Russia’s foreign ministry spokesperson Maria Zakharova said.

On the demand side, further support came from optimism over a demand recovery in China, the world's largest crude buyer.

China reported fewer COVID-19 infections than on Nov. 29, while the market speculated that weekend protests could prompt an easing in travel restrictions.

Guangzhou, a southern city, relaxed COVID prevention rules in several districts on Nov. 30.

A fall in the U.S. dollar was also bullish for prices. A weaker greenback makes dollar-denominated oil contracts cheaper for holders of other currencies, and boosts demand.

Fed Chair Jerome Powell is scheduled to speak about the economy and labor market on Nov. 30, with investors looking for clues about when the Fed will slow the pace of its aggressive interest rate hikes.
