Oil prices jumped more than 5 percent on Friday as big Middle East producers in OPEC agreed to reduce output to drain global fuel inventories and support the market.
Benchmark Brent crude oil rose $3.26 a barrel to a high of $63.32 by 1355 GMT. In early trade, Brent had fallen below $60 when it looked as if oil exporters might not agree.
US light crude rose $2.62 to a high of $54.11 a barrel before slipping to around $53.90.
Prices fell almost 3 percent on Thursday after the Organization of the Petroleum Exporting Countries ended a meeting in Vienna with only a tentative deal to tackle weak prices. Talks with other producers were held on Friday.
Oil prices have plunged 30 percent since October as supply has surged and global demand growth has weakened.
OPEC is seeking support from non-OPEC Russia for supply cuts. Russian Energy Minister Alexander Novak returned to Vienna on Friday after discussing the issue with President Vladimir Putin.
A Russian Energy Ministry source said Moscow was ready to contribute a cut of around 200,000 bpd and sources said other non-OPEC producers could contribute a further 200,000 bpd of output cuts, bringing an overall cut to 1.2 million bpd.
“(A cut of) 1.2 million bpd, if implemented promptly and fully, should be enough to largely attenuate, but not eliminate, expected implied global inventory builds in the first half of next year,” BNP Paribas strategist Harry Tchilinguirian told Reuters Global Oil Forum.
“Given how much expectations were downplayed yesterday, this comes as a welcome surprise for the market,” he added.
Oil output from the world’s biggest producers - OPEC, Russia and the United States - has increased by 3.3 million bpd since the end of 2017 to 56.38 million bpd, meeting almost 60 percent of global consumption.
The surge is mainly due to soaring US oil production which has jumped by 2.5 million bpd since early 2016 to a record 11.7 million bpd, making the United States the world’s biggest producer.
