NEW YORK, June 18 (Reuters) - Oil prices rose slightly Thursday as a panel of OPEC and its allies met to review record oil supply cuts, even as the market remained concerned about additional coronavirus cases reported in parts of the United States and China.
Brent crude LCOc1 futures were up 54 cents at $41.25 a barrel by 11:23 a.m. EST (1523 GMT) and U.S. West Texas Intermediate (WTI) crude CLc1 futures rose 59 cents to $38.55 a barrel.
"You're going to see more OPEC compliance," said Phil Flynn, senior oil analyst at Price Futures Group in Chicago. "I think we'd be a lot higher if it weren't for these coronavirus fears."
An OPEC+ ministerial panel met on Thursday to review record oil supply cuts and plans by countries such as Iraq and Kazakhstan to improve compliance with quotas to support oil prices battered as demand plunged by up to a third during the pandemic.
The Organization of the Petroleum Exporting Countries and allies, known as OPEC+, have been cutting output by a record 9.7 million barrels per day (bpd) or 10% of global supply since May 1. discussion was unlikely to recommend an extension of record cuts into August, sources said. OPEC+ compliance with production cut commitments in May was 87%, two OPEC+ sources said on Wednesday.
