Oil edged up on Tuesday, supported by a recovery in the equities market, but still struggled to shake off Monday's decline.
U.S. West Texas Intermediate futures finished Tuesday's session up 50 cents at $63.51 a barrel.
International benchmark Brent crude futures were last up 35 cents on the day at $67.99 a barrel by 2:13 p.m. ET. Brent rose last week to $71 a barrel, close to its highest so far this year, but failed to hold on to that level.
The oil price fell by about 3 percent on Monday, following a sharp sell-off on Wall Street as the tech sector came under fire.
"There's not really one catalyst for crude being up today," said John Macaluso, analyst at Tyche Capital Advisors. The gains were in part the result of a technical rebound from Monday's losses, as well as a recovery in the equities market, Macaluso said.
