Global oil prices declined sharply on Monday after the United States and Iran concluded a high-level diplomatic engagement in Switzerland, with Tehran announcing it had secured critical waivers for its petroleum exports. The development significantly eased immediate fears of a supply disruption that had rattled markets earlier in the session.
Brent crude, the international benchmark, fell $1.53, or 1.90%, to settle at $79.04 a barrel by 0656 GMT. The decline erased early gains that had pushed prices as high as $8230 at the start of trading. The initial spike was fueled by a rocky beginning to the negotiations, marked by threats from US President Donald Trump to resume military pressure on Iran and Tehran’s own announcement that it had again closed the strategic Strait of Hormuz.US Texas Intermediate (WTI) crude futures for the front-month contract, which expires later Monday, traded at $76.53 a barrel, down 7 cents. The more actively traded August contract fell 55 cents to $75.30 a barrel. There was no WTI settlement on Friday due to a US holiday.
Diplomatic Breakthrough Eases Supply Fears
Mediators confirmed that high-ranking US and Iranian officials had wrapped up their first round of talks. The dialogue, which began on Sunday, operated under a memorandum of understanding reached last week to extend a fragile ceasefire from April for at least another 60 days.Iranian Foreign Minister Abbas Araqchi provided concrete details of the progress, stating his country had obtained waivers for oil and petrochemical exports, the release of some frozen assets, and the initiation of a reconstruction and development plan for.
“High-level talks between the US and Iran in over the weekend appear to produced some progress, with both sides agreeing to establish a high-level committee,” said IG market analyst Tony Sycamore. “However, whether these steps will deliver meaningful results on the ground remains to be seen, particularly in Southern Lebanon where both Israel and Hezbollah seemingly intent on continuing their struggle.”
2>Strait of Hormuz and Regional Flashpoints
Prior to the diplomatic breakthrough, shipping data showed the number of vessels transiting the Strait of Hormuz fell sharply on Sunday after Iran announced the waterway’s closure. The move was a response to what Tehran described as Israeli and US violations of the interim peace agreement.
Compounding regional instability, Israeli strikes in Lebanon killed at least 20 people on Saturday, according to Lebanon’s state news agency NNA. The violence occurred just one day after a ceasefire with Hezbollah was supposed to take effect, underscoring the fragility of the broader security environment.
“Recent developments show that moving towards a more permanent deal will be challenging, with real risks of a flare-up in hostilities during the 60-day ceasefire,”G analysts warned in a research note.
Supply Outlook Shifts
Despite the pockets of violence, the overall trajectory for oil prices pointed downward last week, with crude falling more than 8%. The decline was driven by optimism over a potential flood of new supply. Traders anticipate the release of cargoes stranded inside the Gulf and the possible lifting of US sanctions on Iranian oil as part of a comprehensive deal.
Hamid Bovard, the head of the National Iranian Oil Company, told state television on Sunday that over 25 million barrels of Iranian oil have passed through the virtual blockade line since Monday. In a further sign of easing market tightness, the United Arab Emirates, Kuwait, and Iraq have all offered additional crude volumes to customers over the past week. Iraq’s deputy oil minister for upstream affairs also announced plans to gradually restore crude production to between 4.2 million and 4.3 million barrels per day.
