Oil prices inched higher on Tuesday as the dollar eased, but global recession worries and concerns about China’s rising COVID-19 case numbers denting demand from the world’s top crude oil importer weighed on sentiment, according to Reuters.

Brent crude futures rose 44 cents, or 0.5%, to $87.89 by 0513 GMT. U.S. West Texas Intermediate (WTI) crude futures for January began trading Tuesday, rising 30 cents, or 0.4%, to $80.34 a barrel.

Both benchmarks had dived more than $5 a barrel on Monday, hitting 10-month lows, after the Wall Street Journal (WSJ) reported an increase of up to 500,000 barrels per day would be considered at the OPEC+ meeting on Dec. 4.

Prices rebounded quickly in full after Saudi Arabian energy minister Prince Abdulaziz bin Salman said the kingdom is sticking with output cuts and not discussing a potential oil output increase with other OPEC oil producers, state news agency SPA reported, denying the WSJ report.

The Organization of the Petroleum Exporting Countries and its allies (OPEC+) recently cut production targets and the energy minister of de facto leader Saudi Arabia said this month that the group will remain cautious on oil production because of uncertainty about the global economy.

The pullback in the U.S. dollar was the main factor supporting oil prices after Monday’s rebound, CMC Markets analyst Tina Teng said. A weaker greenback makes oil cheaper for holders of other currencies.

Concerns over oil demand amid the U.S. Federal Reserve’s interest rate tightening and China’s strict COVID lockdown policies are outweighing potential positive price drivers like a European Union embargo on Russian oil set to start on Dec. 5, Stephen Innes, managing partner at SPI Asset Management, said in a note.

A G7 plan also set to take effect on Dec. 5 will allow shipping services providers to help to export Russian oil, but only at enforced low prices.

“The critical risk to a price cap policy is the potential for Russian retaliation, which would turn this into an additional bullish shock for the oil market,” Innes said.

But in the meantime, China’s fresh nationwide spike in COVID cases has deepened concerns about its economy.

Beijing shut parks and museums on Tuesday and more Chinese cities resumed mass testing. The Chinese capital on Monday warned that it is facing its most severe test of the pandemic and tightened rules for entering the city.

In the United States, crude oil stocks were estimated to have dropped by about 2.2 million barrels in the week to Nov. 18, a preliminary Reuters poll showed on Monday.

The front-month Brent crude futures spread narrowed sharply last week, while WTI flipped into contango, which suggests supply concerns are easing.
