Monday saw oil markets plunge following a landmark U.S.-Iran agreement to cease hostilities and restore access to the Strait of Hormuz, which has strangled global energy supplies for more than three months.
Brent crude futures shed $3.65, or 4.2%, falling to $83.68 a barrel by 06:30 GMT, while U.S. West Texas Intermediate dropped even more sharply, declining $4.13, or 4.9%, to settle at $80.75.
Both benchmarks touched their lowest levels since March 10, extending losses that had already exceeded 3% on Friday, a sign that traders had begun pricing in a diplomatic breakthrough even before it was officially confirmed.
The breakthrough came after weeks of behind-the-scenes negotiations facilitated by Pakistan, which has quietly served as a key mediating power between Washington and Tehran.
Pakistan’s prime minister confirmed on Monday that the two nations are set to formalize their agreement by signing a memorandum of understanding in Switzerland this coming Friday, a setting that evokes the long tradition of neutral ground diplomacy that has resolved some of history’s most entrenched conflicts.
U.S. President Donald Trump, never one to undersell a moment, announced on Sunday that the Strait of Hormuz would reopen “toll-free” and pledged to end the U.S. naval blockade that had choked Iranian ports during the conflict.
Iran’s deputy foreign minister, Kazem Gharibabadi, confirmed the deal from Tehran’s side, adding that a more comprehensive and permanent agreement would be hammered out during a 60-day ceasefire period, suggesting the two sides are far from finished but have stepped decisively back from the brink.
Iran’s semi-official Mehr news agency reported that the draft deal requires the Strait of Hormuz to be reopened within 30 days, under Iranian-led logistical arrangements, a detail that signals Tehran’s insistence on preserving a degree of sovereign control over the process, even as it concedes to international pressure.
For energy traders, Monday’s price action amounted to a rapid and long-overdue repricing of global oil risk. Since the closure of the Strait of Hormuz, a waterway through which approximately one-fifth of the world’s oil and liquefied natural gas supplies ordinarily pass, markets have been operating under a significant geopolitical risk premium.
Millions of barrels of oil and gas supply have been lost over the past three months alone, sending shockwaves through energy-importing economies already strained by elevated costs.
“The geopolitical risk premium that had been built into crude is now being unwound quite aggressively as traders price in the prospect of restored oil flows,” said Tim Waterer, chief market analyst at KCM Trade, a sentiment that neatly encapsulated the mood across trading floors from London to Singapore on Monday morning.
Vivek Dhar, a commodities strategist at the Commonwealth Bank of Australia, offered a notably measured perspective, pointing out that oil flows through the Strait of Hormuz do not need to return to full pre-war volumes to normalize the market.
“Oil flows through the Strait of Hormuz just need to reach 60-70% of pre-war levels to return oil markets to pre-war oversupply expectations,” he wrote in a research note, a point that suggests the supply shock, while severe, may be easier to reverse than some had feared.
Despite the optimism rippling through energy markets, analysts and industry insiders were careful to draw a clear distinction between the signing of a deal and the actual restoration of supply chains.
Three months of conflict have left physical damage to oil infrastructure across the region, and the logistical challenges of safely resuming tanker traffic through a previously blockaded strait are not trivial.
“While the conflict may have come to an end and oil flows through the Strait of Hormuz may gradually return to normal, the damage already done cannot be reversed overnight,” warned Priyanka Sachdeva, senior market analyst at Phillip Nova. “This includes not only any physical damage to oil infrastructure but also the economic strain endured by oil-importing economies that have faced elevated energy costs for months.”
Investors are watching particularly closely to see how quickly Middle Eastern producers can ramp production back up to pre-war levels and whether international shipping companies will be willing to rapidly re-enter a region that, until days ago, was considered a war zone.
Insurance premiums for vessels transiting the area remain elevated, and it may take weeks before maritime traffic returns to anything approaching normalcy.
In a notable show of momentum, the E4 nations, the United Kingdom, France, Germany, and Italy, jointly announced on Sunday that they stand ready to lift sanctions on Iran in response to concrete steps from Tehran on its nuclear program.
The statement signals a potential diplomatic thaw that, if sustained, could reshape the Middle East’s economic and political landscape for years to come.
“Beyond the immediate price reaction, attention will now shift toward the pace of actual supply normalization and compliance with the agreement,” said Sachdeva, a reminder that in diplomacy, as in markets, the hard work often begins after the headlines fade.
As the ink dries on what may prove to be one of the most consequential energy-related diplomatic agreements of the decade, the world will be watching Bern on Friday with bated breath.
The memorandum of understanding expected to be signed in Switzerland is not an endpoint; it is a starting gun. Whether the fragile accord holds, and how swiftly the arteries of global energy supply can be restored, will determine not just the direction of oil prices but also the stability of an already turbulent world economy.
WHAT YOU SHOULD KNOW
The United States and Iran have reached a preliminary peace deal that will reopen the Strait of Hormuz, a waterway critical to one-fifth of the world’s oil and gas supply, sending oil prices tumbling to three-month lows.
While markets have reacted with immediate relief, the path to full supply normalization remains uncertain. Physical damage to infrastructure, shipping hesitancy, and the still-fragile nature of the ceasefire mean that lower energy prices are not guaranteed overnight.
The deal is promising, but the world should temper its optimism: an agreement on paper and restored oil flows in practice are two very different things.
