Brent crude jumps 4%, as US strikes in Iran set back hopes for Hormuz re-opening

By Scott DiSavino
NEW YORK, May 26 (Reuters) – Brent crude oil futures rose nearly 4% on Tuesday after the U.S. military launched an attack on Iran; This dashed hopes that the United States and Iran would reach an agreement over the weekend to end the three-month war that would reopen shipping through the critical Strait of Hormuz.
However, US futures fell on Monday, when US markets were closed, catching up with the selling wave in Brent.
Global benchmark Brent settled at $99.58 per barrel, up $3.44, or 3.6%, while U.S. West Texas Intermediate (WTI) crude fell $2.71, or 2.8%, to settle at $93.89.
Brent closed at its lowest level since April 20 on Monday, losing 7 percent on renewed hopes of a deal between the United States and Iran. US crude oil fell on Monday as the market was closed for the US Memorial Day holiday.
WTI closed at its lowest level since April 22 on Tuesday, while US gasoline futures fell 7% and US diesel futures fell 4% to their lowest closes in five weeks.
U.S. officials have said on various occasions that they are close to a deal with Iran to end the conflict, but have been unable to reach an agreement beyond a temporary ceasefire that would minimize attacks.
Iran on Tuesday said the United States had violated a ceasefire after launching defensive strikes in southern Iran, while U.S. Secretary of State Marco Rubio said negotiating a deal to stop the conflict “could take several days.”
Iran’s foreign ministry said the US strikes in Iran’s southern Hormozgan province, where Iranian media reported the sounds of explosions early Tuesday, were a “grave violation” of the tenuous ceasefire that has been in place for nearly seven weeks.
Both sides have previously said progress is being made on a memorandum of understanding that could stop the war and restart shipping through the blockaded Strait of Hormuz, giving negotiators 60 days to discuss more complex issues, including Iran’s nuclear program.
“We are still waiting for more details on a potential deal,” said Giovanni Staunovo of UBS. “Meanwhile, we are seeing renewed tensions in the Middle East while passages through the Bosphorus remain restricted.”
The US attack came as Iran’s chief negotiator and foreign minister were in Doha to meet with the Qatari prime minister in a bid to reach a deal.
TANKERS MONITORED PASSING THROUGH THE straits
Iran has effectively halted almost all non-Iranian ships entering and exiting the Strait of Hormuz since the war began in late February, blocking nearly a fifth of global oil and liquefied natural gas (LNG) flows.
