(Reuters) -Oil prices climbed for a third straight session on Friday, shrugging off concerns about global economic growth as worries about tightening supplies underpinned prices ahead of an impending European Union embargo on Russian oil.

Brent futures rose 84 cents, or 0.8%, to $111.74 a barrel by 0306 GMT, while U.S. West Texas Intermediate (WTI) crude climbed 80 cents, or 0.7%, to $109.06 a barrel.

Brent and WTI are on track to rise for a second week in a row, buoyed by the EU’s proposal to phase out supplies of Russian crude oil in six months and refined products by the end of 2022. It would also ban all shipping and insurance services for transporting Russian oil. The plan still requires unanimous backing from the 27 countries in the bloc.

“There are concerns over global growth and what it could mean for oil demand,” said Warren Patterson who heads ING’s commodities research.

“However, the looming EU ban on Russian oil more than offsets this for now, and so should limit the downside for prices.”

Wall Street stocks tumbled on Thursday as investors worried that aggressive central bank policies around the world aimed at tamping down inflation could shackle growth.

The Bank of England warned Thursday that Britain risks a double-whammy of a recession and inflation above 10% as it raised interest rates to their highest since 2009, hiking by quarter of a percentage point to 1%.

On supply, the Organization of the Petroleum Exporting Countries, Russia and allied producers, known as OPEC+, agreed as expected to another modest monthly increase in oil output.

Ignoring calls from Western nations to hike output more, OPEC+ agreed to raise June production by 432,000 barrels per day, in line with its plan to unwind curbs made when the pandemic hammered demand.

Investors are also eyeing higher demand from the United States this fall as Washington unveiled plans to buy 60 million barrels of crude for its emergency stockpiles.

A U.S. Senate panel advanced a bill that could expose OPEC+to lawsuits for collusion on boosting oil prices. Congress hasfailed to pass versions of the legislation for more than twodecades, but lawmakers are worried about rising inflation andhigh gasoline prices.
