Oil prices rose by more than $1 today in response to tighter supplies and on news that China is considering a cut in the duration of quarantine for inbound visitors.

Brent crude futures rose $1.15, or 1.2%, to $93.56 a barrel this afternoon.

US West Texas Intermediate crude for November delivery, which expires today, rose $1.54, or 1.8%, to $87.09 per barrel. The WTI contract for December delivery was up 1.7%, or $1.43, at $85.95 a barrel.

"Oil prices are extending their ascent at the time of writing amid reports that China is considering cutting Covid quarantine measures for visitors," PVM Oil's Stephen Brennock said.

China, the world's largest crude importer, has stuck to strict Covid-19 curbs this year, which weighed heavily on business and economic activity, lowering demand for fuel.

Bloomberg news reported today that Beijing is considering cutting the quarantine period for inbound visitors to seven days from 10 days, citing people familiar with the matter.

A looming European Union ban on Russian crude and oil products, as well as the output cut from the Organization of the Petroleum Exporting Countries and other producers including Russia, known as OPEC+, have also supported prices.

OPEC+ agreed on a production cut of 2 million barrels per day in early October.

Separately, US President Joe Biden announced a plan this week to sell off the rest of his release from the nation's emergency oil reserve by year's end, or 15 million barrels of oil, and begin refilling the stockpile as he tries to dampen high gasoline prices ahead of midterm elections on November 8.

The announcement, however failed to ease oil prices, as official US data showed that US SPR reserves last week fell to their lowest since mid-1984, while commercial oil stocks fell by more than expected.

"Yesterday's failed attempt at cooling oil prices is further evidence that the US has lost its influence over global oil markets," Brennock said.

Meanwhile, global demand for fuel remains uncertain.

US economic activity expanded modestly in recent weeks, although it was flat in some regions and declined in a couple of others, the Federal Reserve said on Wednesday in a report that showed firms growing more pessimistic about the outlook.
