Oil prices were at the highest in more than three months on Thursday, buoyed by hopes of an end to the China-U.S. trade fight and by a report showing lower U.S. crude inventories.
Brent crude gained 71 cents, or 1%, to trade at $67.91. U.S. West Texas Intermediate crude gained 57 cents, or 0.93%, to settle at $61.88 per barrel. Both benchmarks were their strongest since Sept. 17.
U.S. President Donald Trump said on Tuesday he and Chinese President Xi Jinping would have a signing ceremony for the so-called Phase 1 agreement to end their trade dispute that was put together earlier this month.
The prospect of a signed deal boosted Wall Street to fresh highs, helping to support crude futures, which often to follow equities. "For now, the complex appears poised to further ride the wave of increasing risk appetite that is being vividly underscored by the advancing equities into new record high territory," Jim Ritterbusch, president of trading advisory firm Ritterbusch and Associates, said in a note.
The roughly 17-month trade war between the world's two largest economies has hit global growth and demand for oil.
Even so, Brent has still rallied 25 percent in 2019, supported by supply cuts by the Organization of the Petroleum Exporting Countries and allies including Russia.
Also supporting prices, the American Petroleum Institute, an oil industry group, said late on Tuesday that U.S. crude stocks fell by 7.9 million barrels last week, much more than forecast by analysts.
Trading volume remains low due to the Christmas holiday, which has delayed the release of the U.S. government's official oil inventory report by two days until Friday.
The so-called OPEC+ group agreed this month to extend and deepen production cuts that would take as much as 2.1 million barrels per day (bpd) of supply off the market from Jan. 1, or roughly 2% of global demand.
Still, U.S. producers, not party to the OPEC+ agreement, have been pumping record amounts of oil, especially shale. Growth in U.S. production is forecast by many to slow in 2020.
"Oil prices continue to show year-end strength, supported by a combination of definitive progress on the U.S.-China trade deal, the December OPEC/OPEC+ agreement and slowing shale activity," said Stephen Innes, chief Asia market strategist at AxiTrader.
But more supply is coming in the new year from OPEC members Saudi Arabia and Kuwait, which this week agreed to end a dispute over their Neutral Zone, which can supply as much as 500,000 bpd.
