Oil prices dipped on Thursday, August 13, 2026, as investors assessed prospects for weaker global demand in 2026.
Brent futures slipped 11 cents, or 0.12%, to $88.87 a barrel by 0624 GMT, trimming gains over the prior six sessions.
U.S. West Texas Intermediate (WTI) crude fell 16 cents, or 0.19%, to $83.11, after advancing over the past five sessions.
A senior market analyst at XS.com, Antonio Di Giacomo, said: “Buyers continue to dominate in the short term, following the recovery over the past several sessions.
“However, the speed of the advance could also trigger periods of volatility and profit-taking around current levels.”
Di Giacomo added that the market was trying to determine if potential supply constraints from Middle East disruptions would be sufficient to offset possible moderation in global consumption.
“This combination leaves WTI particularly sensitive to both geopolitical developments and new economic and energy data,” he said.

On the same day, the Organization of the Petroleum Exporting Countries (OPEC) lowered its world oil demand growth forecast for 2026 to 580,000 barrels per day in its monthly oil market report.
