LONDONOil prices rose on Feb. 17, underpinned by a major supply disruption in the southern United States this week where a winter storm hit Texas.

Benchmark Brent crude gained $1.37, or 2.2%, to $64.72 a barrel at 5:37 CT.

U.S. West Texas Intermediate (WTI) crude rose $1.18, or 2%, to $61.23 a barrel.

Both contracts were at their highest level since January 2020.

“WTI clocked in at $60 a barrel this week, joining its transatlantic peer (Brent) above the psychological level for the first time since January 2020. At this price point, any oil production is profitable,” said Stephen Brennock of broker PVM.

Oil has been supported in the past few weeks by OPEC+ supply curbs and hopes of a demand rebound due to COVID-19 vaccinations, but severe cold weather in Texas, the country’s largest oil producing state, has boosted the prices in recent days.

The U.S. deep freeze is expected to disrupt production for several days if not weeks, industry experts said, as wellheads have frozen and refineries have been shut.

ANZ and Citigroup analysts estimated at least 2 million barrels per day (bbl/d) of U.S. shale oil production had been curtailed. Citi estimated a cumulative production loss of around 16 million barrels through early March.

The stronger price environment has put more attention on OPEC+, which groups OPEC, Russia and allied producers. It meets to set policy on March 4.

“The impact on crude oil prices will largely depend on how long the power crisis will last, but eventually prices will likely return to the fundamentals with a focus on the global energy demand and OPEC+,” said Margaret Yang, a strategist at Singapore-based DailyFX.

OPEC+ oil producers are likely to ease curbs on supply after April given a recovery in prices, OPEC+ sources told Reuters.

“We believe that OPEC+ will likely take a more conservative approach, and ease output more modestly,” said ING analyst Warren Patterson.

U.S. oil inventory data from API and the U.S. Energy Information Administration will be released on Feb. 17 and Feb. 18 respectively, a one-day delay for each after this week’s U.S. holiday.

Analysts polled by Reuters estimated, on average, that crude stocks fell 2.2 million barrels in the week to Feb. 12.
