Oil prices climbed about 3% to a two-month high on May 26 on signs of tight supply ahead of U.S. summer driving season, as the EU wrangled with Hungary over plans to ban crude imports from Russia over its invasion of Ukraine.

Brent futures rose $3.52, or 3.1%, to $117.55/bbl by 1:34 p.m. EDT. WTI crude in the U.S. rose $3.97, or 3.6%, to $114.30.

Brent was on track for its sixth straight daily gain and highest close since March 25. WTI was headed for its highest close since March 23.

“Crude prices rose as a tight oil market was going to remain in place given the start of the summer driving season was going to keep a downward trajectory for U.S. stockpiles,” said Edward Moya, senior market analyst at data and analytics firm OANDA.

Crude drew support from a big weekly drawdown in U.S. crude inventories, reported on May 25.

“The fundamental backdrop ... is getting price supportive ... and will turn even more bullish once the EU sanctions on Russian oil sales are endorsed by all parties involved,” PVM Oil’s Tamas Varga said.

European Council President Charles Michel said he was confident an agreement can be reached before the council’s next meeting on May 30.

Hungary remains a stumbling block, as EU sanctions require unanimous support. Hungary is pressing for about 750 million euros (US$800 million) to upgrade its refineries and expand a pipeline from Croatia.

Even without a formal ban, much less Russian oil is available as buyers and trading houses have avoided suppliers from the country.

Russia’s oil production should decline to 480-500 million tonnes this year from 524 million tonnes in 2021, state-run news agency RIA reported, citing Deputy Prime Minister Alexander Novak.

OPEC+ meets on June 2 and is expected to stick to last year’s deal to raise July output targets by 432,000 barrels per day, six OPEC+ sources told Reuters, rebuffing Western calls for a faster increase to control prices.

Other factors also are supporting oil prices.

“Shanghai is preparing to reopen after a two-month lockdown, while the U.S. peak driving season begins with the Memorial Day weekend,” said Sugandha Sachdeva, vice president of commodities research at Religare Broking. The U.S. celebrates Memorial Day on May 30.

The U.S. government confiscated an Iranian oil cargo held on a Russian-operated ship near Greece and will send the cargo to the United States aboard another vessel.

Britain announced a 25% windfall tax on oil and gas producers’ profits, alongside a 15 billion pound (US$18.9 billion) package of support for households struggling to pay energy bills.

Hungary announced new windfall taxes worth 800 billion forints (US$2.19 billion) on “extra profits” earned by banks, energy companies and other firms.
