Oil prices rose by more than $1 a barrel on Monday after top crude exporter Saudi Arabia pledged to cut production by a further 1 million barrels per day (bpd) from July to counter macroeconomic headwinds that have depressed markets.
Brent crude futures were up $1.72, or 2.3%, at $77.85 a barrel by 0900 GMT after touching a session high of $78.73.
U.S. West Texas Intermediate crude climbed $1.72, or 2.4%, to $73.46 after hitting an intraday high of $75.06.
The voluntary cut is on top of a broader deal by the Organization of the Petroleum Exporting Countries (OPEC) and allies including Russia to limit supply into 2024 as the OPEC+ producer group seeks to boost flagging oil prices.
OPEC+ pumps about 40% of the world's crude and has cut its output target by a total of 3.66 million bpd, amounting to 3.6% of global demand.
"Saudi will probably continue doing whatever it takes to keep oil prices elevated ... and take calculated pre-emptive steps to ensure the macro concerns potentially affecting demand are negated."
Consultancy Rystad Energy said the additional Saudi cut is likely to deepen the market deficit to more than 3 million bpd in July, which could push prices higher in the coming weeks.
Goldman Sachs analysts said the meeting was "moderately bullish" for oil markets and could boost December 2023 Brent prices by between $1 and $6 a barrel depending on how long Saudi Arabia maintains output at 9 million bpd over the next six months.
Many of the OPEC+ reductions will have little real impact, however, as the lower targets for Russia, Nigeria and Angola bring them into line with their actual production levels.
In contrast, the United Arab Emirates (UAE) was allowed to raise output targets by 200,000 bpd to 3.22 million bpd to reflect its larger production capacity.
