Oil soared nearly 4 percent on Tuesday, supported by tight supply and expectations that rising coronavirus cases and the spread of the Omicron variant will not derail a global demand recovery.
Brent crude gained $2.85, or 3.5 percent, to $83.72 a barrel, its highest settlement since early November. The global benchmark dropped 1 percent on Monday.
US West Texas Intermediate (WTI) rose $2.99, or 3.8 percent, to end at $81.22, also its highest price since mid-November. On Monday, it fell 0.8 percent.
United States Federal Reserve Chair Jerome Powell said he expects the economic impact of Omicron to be short-lived, adding that ensuing quarters could be very positive for the economy after the surge driven by the variant subsides.
"Omicron has yet to wreak the havoc of the Delta variant and may never do so, keeping the global recovery on track," said Jeffrey Halley, analyst at brokerage OANDA.
Brent rose by 50 percent in 2021 and has rallied further in 2022 as demand has recovered to near pre-pandemic levels while the Organization of the Petroleum Exporting Countries and its allies, collectively known as OPEC+, slowly ease record output cuts made in 2020.
However, lack of capacity in some OPEC nations has kept supply additions below the 400,000-barrel-per-day (bpd) increase agreed to last year among the group.
Recent outages in Libya have also buoyed prices, and the National Oil Corp said it was suspending exports from the Es Sider terminal.
"Combination of facts – that demand is going to be stronger than anticipated and that OPEC's supply may not grow as fast as the demand - is why prices are climbing," said Phil Flynn, senior analyst at Price Futures Group.
US crude inventories dropped by about 1.1 million barrels last week, according to market sources citing American Petroleum Institute, less than the 2 million-barrel draw estimated in a Reuters poll. Official government data is due on Wednesday.
European refiners' crude and oil products stocks in December dropped by more than 11 percent from a year earlier, Euroilstock data showed. At the same time, European jet fuel refining margins, are back to pre-pandemic levels as global aviation activity recovers despite the spread of Omicron.
Meanwhile, the US government lowered its oil output growth estimates, while raising its oil demand forecast.
Production was estimated to rise by 640,000 bpd this year, lower than last month's forecast of a 670,000 bpd increase. Total oil demand was now seen rising 840,000 bpd for the year, higher than the 700,000-bpd increase expected last month. It is estimated to rise by another 330,000 bpd in 2023.
