Oil climbed to a two-year high as U.S. industry data showed crude stockpiles resumed declines and investors awaited a decision by OPEC on extending output cuts.

January futures rose as much as 2.2 percent in New York, the highest since mid-2015. U.S. inventories fell by 6.36 million barrels last week, the American Petroleum Institute was said to report. That’s more than forecast in a Bloomberg survey, which shows a drop of 2.2 million barrels ahead of government data later Wednesday.

Oil has risen this month on speculation that the Organization of Petroleum Exporting Countries and its partners will decide to prolong supply cuts beyond March when they meet in Vienna next week. Saudi Arabia, OPEC’s de facto leader, has been reducing exports as well as production, with shipments in September dropping to the lowest since March 2011, according to official data submitted to the JODI global database.

“It does appear the only way is up for oil,” said Michael McCarthy, a chief strategist at CMC Markets in Sydney. “A lot of traders are speculating about the potential outcome of the OPEC meeting. Expectations are high and that could lead to disappointment if OPEC and its partners don’t deliver, but it doesn’t seem many are prepared to take the risk of that happening.”

West Texas Intermediate for January delivery gained as much as $1.22 to $58.05 a barrel on the New York Mercantile Exchange, and was at $57.81 as of 12:04 p.m. London time. The contract advanced 41 cents to $56.83 on Tuesday.

Brent for January settlement increased 57 cents, or 0.9 percent, to $63.14 a barrel on the London-based ICE Futures Europe exchange after climbing 0.6 percent on Tuesday. The global benchmark traded at a premium of $5.35 to WTI.

U.S. crude stockpiles at Cushing, Oklahoma, the delivery point for WTI and the biggest oil-storage hub, dropped by 1.8 million barrels last week, the API said, according to people familiar with the data. Gasoline inventories expanded by 869,000 barrels, API data show.

Oil-market news:

• Andy Hall, the veteran crude trader who closed his hedge fund this year, will brief OPEC officials on the outlook for U.S. shale oil, according to a copy of the agenda seen by Bloomberg News.
• The front-month contract for WTI futures on the New York Mercantile Exchange just turned more expensive than the second-month contract. The market hasn’t settled in that structure, known as backwardation, since November 2014.
