Oil prices extended losses today on profit taking and a stronger US dollar, but overall optimism about recovering demand kept a floor under prices.
Brent crude was down 58 cents, or 0.8%, at $70.91 a barrel today, after declining 0.6% yesterday.
US West Texas Intermediate oil was off by 55 cents, or 0.8%, at $68.68 a barrel, having dropped by 0.6% in the previous session.
"A previous price surge that was probably premature, coupled with a stronger U.S. dollar and a correction on the stock markets, are weighing on oil prices," Commerzbank said.
As oil is priced in dollars, a stronger greenback makes crude more expensive for buyers with other currencies.
Data showing China's crude imports were down 14.6% in May on a yearly basis also weighed on prices.
"China was taking advantage of low oil prices a year ago, so the base is uncharacteristically high," oil brokerage PVM noted.
Heavy Chinese refinery maintenance in May also contributed to the decline.
Crude prices have risen in recent weeks, with Brent up by nearly 40% this year and WTI gaining even more, amid expectations of demand returning as some countries succeed in vaccinating populations against Covid-19.
Restraint on supply by the Organization of the Petroleum Exporting Countries and allies has also helped buttress prices.
