On August 12, the international oil price fell slightly. The settlement price of the main contract in the U.S. WTI crude oil futures market was $69.09/ barrel, down $0.16, and the settlement price of the main contract in the Brent crude oil futures market was $71.31/ barrel, down $0.13. Previously, the oil price rebounded sharply for two consecutive trading days due to the improvement of U.S. employment data and fuel demand. However, under the background of the accelerated spread of delta virus, the recovery of global oil demand is still dragged down, and the upward resistance of oil price is heavy.
