Oil heads for weekly gains despite US sanctions waiver on Russian oil

• Measures aimed at easing supply tightness fail to calm markets.
• Disruption of trade through Strait of Hormuz is 'fundamental'.
• Brent more susceptible to energy security issues than WTI.
  

Oil prices headed for ​weekly gains as of Friday, despite the US trying to ease supply concerns by issuing a ‌30-day license for countries to buy Russian oil and petroleum products stranded at sea.

Brent futures for May rose 10 cents, or 0.1%, to $100.56 a barrel by 0400 GMT, heading for about a 9% weekly increase. US West Texas Intermediate (WTI) crude for April was down 16 cents, or 0.2%, ​at $95.57 a barrel, though also poised for a 7% uptick for the week.

The license was issued in what ​Treasury Secretary Scott Bessent said was a step to stabilise global energy markets roiled by ⁠the US-Israeli war on Iran, but analysts said this has failed to resolve wider supply constraints.

"ICE Brent futures have already breached $100 ​per barrel and are still supported today, despite moves to calm the markets with the Russian oil waiver and the ​unprecedented release of emergency stockpiles," said Emril Jamil, senior analyst at LSEG.

"The market sees this as a short-term solution that does not address the crux of the supply disruption. The crude intermonth spreads for future months indicate an unresolved and continued tightness in supply," Jamil said.

Brent is ​more supported than WTI as Europe is more susceptible to energy security issues, while the US is able to stave ​off its exposure due to its domestic output, Jamil said.

Yang An, analyst at Haitong Futures, said: "Issuing the license has eased market concerns, ‌but it ⁠won't resolve the most fundamental issue. The most important thing is the restoration of navigation in the Strait of Hormuz."

The announcement on Russian oil came a day after the US Energy Department said the US would release 172 million barrels of oil from its Strategic Petroleum Reserve to help curb skyrocketing oil prices.

That plan was coordinated with the International Energy Agency, which ​has agreed to release a ​record 400 million barrels of oil ⁠from strategic stockpiles, including the US contribution.

Fleeting relief sparked by the IEA release, however, was shattered by a re-escalation of Middle East risks, IG analyst Tony Sycamore said in a ​note.

Both benchmark prices surged more than 9% on Thursday and hit their highest levels since ​August 2022.

Iran's new ⁠supreme leader Mojtaba Khamenei said Iran would fight on and keep the Strait of Hormuz shut as leverage against the United States and Israel.

Two fuel tankers in Iraqi waters were struck by explosive-laden Iranian boats, Iraqi security officials said on Thursday. An Iraqi official ⁠told state ​media that the country's oil ports have completely stopped operations.

Meanwhile, US Treasury ​Secretary Scott Bessent told Sky News in an interview that the US Navy, perhaps with an international coalition, would escort vessels through the Strait of Hormuz ​when it is militarily possible.
