Several of the world's largest oil exporters have announced surprise cuts in production in a move which is expected to push up prices
Saudi Arabia, Iraq and several Gulf states said they were cutting output to support market stability.
Oil prices soared when Russia invaded Ukraine, but are now back at levels seen before the conflict began.
However, the US has been calling for producers to increase output in order to push energy prices lower.
High energy and fuel prices last year helped to drive up inflation - the rate at which prices rise - putting pressure on many households' finances.
The reduction in output - which amounts to more than one million barrels per day - is being made by members of the Opec+ oil producers. The group accounts for about 40% of all the world's crude oil output.
Saudi Arabia is reducing output by 500,000 bpd and Iraq by 211,000. The UAE, Kuwait, Algeria and Oman are also making cuts.
A Saudi energy ministry official said the move was "a precautionary measure aimed at supporting the stability of the oil market", the official Saudi Press Agency said.
Analysts said they expected oil prices - which are currently at about $80 a barrel - to rise as a result. Oil broker PVM told Reuters that prices could rise by "as much as $3" a barrel, while the head of investment firm Pickering Energy Partners said prices could jump by $10.
The latest reductions come on top of a cut announced by Opec+ in October last year of two million barrels per day (bpd).
However, last year's cut came despite calls from the US and other countries for oil producers to pump more crude.
The Opec+ group includes the Organization of Petroleum Exporting Countries (Opec) as well as other countries including Russia.
Russia has said it will extend its already-announced production cut, of half a million barrels per day, until the end of the year.
