Oil prices stabilised near three-week highs on Thursday after Opec+ agreed to further tighten global crude supply with a deal to slash production by about two million barrels per day, the largest reduction since 2020.

Brent crude futures for December settlement edged down eight cents to $93.29 per barrel by 0656 GMT after settling 1.7pc higher in the previous session.

US West Texas Intermediate (WTI) crude futures for November delivery slid 15 cents to $87.61 per barrel, building on a 1.4pc rise on Tuesday.

The agreement between the Organisation of Petroleum Exporting Countries (Opec) and allies including Russia, a group known as Opec+, comes ahead of a European Union embargo on Russian oil and would squeeze supplies in an already tight market, adding to inflation.

“This latest action from Opec+ suggests that there is upside to our current full year 2023 forecast of $97/bbl,” ING analysts said in a note.

However, given that production at some of the Opec+ countries are below target levels, the actual cut would be smaller than the two million bpd reduction agreed to at the meeting.

Saudi Energy Minister Abdulaziz bin Salman said the real supply cut would be about 1m to 1.1m bpd and they were in response to rising interest rates in the West and a weakening global economy.

The administration of US President Joe Biden has criticised the deal as being “shortsighted”. The White House said President Biden would continue to assess whether to release further strategic oil stocks to lower prices.

The White House said it would consult with Congress on additional paths to reduce Opec and its allies’ control over energy prices in an apparent reference to legislation that could expose members of the group to antitrust lawsuits.

“The final market impact would depend on the duration of the agreement, as Opec+ decided to extend its Declaration of Cooperation until the end of 2023,” Citi analysts said in a note, adding that the supply cuts will keep global inventories low for longer and tighten markets in 2023.

More than half of the one million bpd supply cut is expected to come from the world’s top exporter Saudi Arabia, analysts at RBC Capital said.

Separately on Wednesday, Russian Deputy Prime Minister Alexander Novak said Russia may cut oil output in an attempt to offset the effects of price caps imposed by the West over Moscow’s actions in Ukraine.

A draw in US oil stockpiles last week also supported prices. Crude inventories dropped by 1.4m barrels in the week ended Sept 30 to 429.2m barrels, the Energy Information Administration said.
