Global oil benchmarks pulled back from their lowest levels in nearly a year on Monday, with U.S. crude ending positive, bolstered by talk of an OPEC+ production cut that offset concerns about strict COVID-19 curbs in China, the world’s biggest crude importer.

Price action was volatile. U.S. West Texas Intermediate (WTI) crude settled up 96 cents, or 1.3%, at $77.24, after earlier touching its lowest since December 2021 at $73.60.

Brent crude also briefly turned positive, but settled down 44 cents, or 0.5%, at trade at $83.19 a barrel, having slumped more than 3% to $80.61 earlier in the session for its lowest since Jan. 4, 2022.
