Oil edges down as investors weigh uncertainty over U.S.-Iran strikes

Four commodity vessels transited the Strait of Hormuz, below the 10-day average of around 13, preliminary shipping data from Kpler showed on Wednesday.

Iran also added more ships to the list of vessels it deems non-compliant and subject to fines, confiscation or detention if they try to sail through the strait.

Iraq increased its oil exports to around 2.34 million barrels per day in August from about 1.35 million bpd in July, two Iraqi energy officials said on Wednesday, with September exports also expected to increase as heavy discounts and Iranian approvals for Iraqi tankers to pass through the Strait of Hormuz encouraged buyers.

The U.S. said on Tuesday that 17 million barrels of oil transited the Strait of Hormuz on Monday, calling it the largest volume of crude to pass through the waterway since the U.S.-Israeli war on Iran began.
