Summary Oil prices fell near four-month lows as easing U.S.-Iran tensions and improving tanker flows through the Strait of Hormuz raised hopes of smoother crude exports
TOKYO (Reuters) - Oil prices fell on Wednesday, extending this week's losses and trading near four-month lows hit in the previous session, on signs that more oil tankers stranded in the Gulf since the start of the Iran war are set to move out of the Strait of Hormuz.
Brent crude futures were down 37 cents, or 0.5%, at $76.71 a barrel as of 0043 GMT, and U.S. West Texas Intermediate slipped 36 cents, or 0.5%, to $72.85 a barrel. Both benchmarks declined nearly 1% on Tuesday, touching their lowest levels since early March.
Prices have come under pressure this week after Washington granted Tehran a 60-day sanctions waiver following initial peace talks, allowing it to sell oil, and as hostilities in Lebanon eased.
"Crude oil prices were weighed down by hopes of easing U.S.-Iran tensions and a recovery in oil shipments through the Strait of Hormuz," said Tomomichi Akuta, senior economist at Mitsubishi UFJ Research and Consulting.
"Further progress in nuclear negotiations could push prices back to pre-war levels," he added.
On Tuesday, Oman and Iran agreed to press on with discussions about the future administration of navigation in the Strait. U.S. Secretary of State Marco Rubio said any Iranian attempt to levy transit fees would violate international law.
Still, uncertainty remains over the durability of the accord. U.S. President Donald Trump said on Tuesday that Iran had agreed to nuclear inspections into "infinity," while Tehran said it had made no such concession in negotiations.
Investors are also watching how quickly Middle Eastern producers can restore exports and whether more ships will enter the region.
An Iranian military source told Fars news agency that a limited number of vessels are being allowed to pass through the strait each day under coordination with Iran's Revolutionary Guards Navy.
Ship-tracking data showed that three stranded supertankers passed through the strait on Tuesday. The U.N. shipping agency said an evacuation plan to enable hundreds of ships with 11,000 seafarers stranded in the Gulf to sail through the strait is underway after the U.S.-Iran ceasefire deal.
Meanwhile, crude stocks fell by 765,000 barrels in the week ended June 19, market sources said, citing data from the American Petroleum Institute released on Tuesday. Nine analysts polled by Reuters estimated, on average, that crude inventories fell by about 4.5 million barrels in the last week.
