(Bloomberg) — Oil rebounded as fresh US military strikes in Iran clouded the outlook for an interim deal between Tehran and Washington to reopen the Strait of Hormuz, with the talks set to continue for several more days.

Global benchmark Brent rose toward $98 a barrel after slumping more than 7% on Monday, while West Texas Intermediate was near $92. US forces struck missile-launch sites and boats trying to place mines, US Central Command said, after Iranian media reported explosions around the strait.

Negotiations will still “take a few days” as both sides discuss language in an initial document, Secretary of State Marco Rubio told reporters in India on Tuesday. Crude had retreated sharply in the week’s opening session as President Donald Trump posted that the talks were “proceeding nicely,” while also threatening more attacks if they were unsuccessful.

Oil prices — which rallied in March and April — are still on pace for a loss in May as a fragile ceasefire and push to reopen Hormuz outweigh signs of fast-depleting stockpiles. The strait, the key waterway through which a fifth of the world’s oil and liquefied natural gas flowed during peacetime, remains essentially closed, subject to blockades by the US and Iran.

The US and Iran have been negotiating a deal that would see them extend the ceasefire for about two months, with the US lifting its blockade and Tehran reopening Hormuz. Still, sticking points remain, with Tehran saying it must be able to manage maritime traffic through the chokepoint, something that the US, Arab states and Europe maintain cannot be allowed.

At present, it’s “premature to consider a peace deal will be reached let alone adhered to,” said Saul Kavonic, senior energy analyst at MST Marquee. “There have been claims by both sides of negotiation success, or the strait opening in the past few months already, only for it to not materialize.”

In a separate post, Trump said Tehran’s enriched uranium would preferably be destroyed in Iran, although the material could also be turned over to the US. Washington has cited the Islamic Republic’s nuclear program as a major reason for embarking on the conflict with Israel, maintaining that Tehran poses a threat as it wants to develop nuclear weapons.
