Mediators have proposed a 10-day mutual halt to hostilities between Iran and the United States, sending crude prices tumbling and equity futures rallying as traders priced in a potential de-escalation of the conflict.
The proposal for a 10-day truce between Iran and the US sent Brent crude sliding $1.32 to $86.90 a barrel and lifted Nasdaq 100 futures 1%, as markets weighed the first concrete diplomatic off-ramp in weeks of escalating military exchanges.
"The proposal represents the most serious attempt to restore the Islamabad Memorandum of Understanding since its collapse," a senior Iranian official told Reuters, speaking on condition of anonymity. "Both sides are being asked to cease all military operations for 10 days to create space for negotiations."
The market response was swift and broad. WTI crude fell $1.28 to $80.24 a barrel, while spot gold rose $12.21 to $4,034.40 an ounce, reflecting residual safe-haven demand. The moves reversed part of the previous session's gains, when Brent had climbed above $91 on Monday after Iran declared the interim ceasefire under the Islamabad MoU had ended.
The Strait of Hormuz handles about one-fifth of the world's oil trade, and the conflict has already claimed 17 US service members since hostilities began. If the 10-day truce holds, it could remove a significant geopolitical risk premium from crude prices and ease inflationary pressures that have weighed on equity markets. Failure would likely trigger another leg higher in oil and a renewed flight to safe havens.
The proposal comes after nine consecutive nights of US strikes targeting Iranian military command centers, air defense systems, and maritime assets, according to US Central Command. Iran has responded with missile and drone attacks that have struck targets in Jordan, Kuwait, and Bahrain, including a strike on a Kuwaiti power and water plant.
Iranian Foreign Minister Abbas Araghchi said over the weekend that the country's Supreme National Security Council evaluates war and ceasefire proposals, but the final decision rests with Supreme Leader Mojtaba Khamenei. Araghchi also told state-run IRNA that "the right time to negotiate is precisely when you have achieved a reliable field and strategic achievement on the military front," suggesting Tehran may seek battlefield gains before committing to any truce.
Oil's Geopolitical Risk Premium at Stake
The 10-day proposal targets a revival of the Islamabad Memorandum of Understanding, the interim ceasefire agreement that collapsed in recent weeks. Iran's Supreme Leader Khamenei had called the US president's signature "utterly worthless and devoid of credibility" after accusing Washington of repeated violations. The last time a similar diplomatic channel opened during the initial Islamabad talks, Brent crude fell more than 5 percent over a two-week period as traders unwound war premiums.
For equity markets, the stakes are equally high. The Nasdaq 100's 1 percent gain in futures trading suggests investors see a truce as reducing both energy cost pressures and uncertainty around global supply chains. A sustained de-escalation could shift focus back to Federal Reserve policy and corporate earnings, while a breakdown would likely renew the risk-off rotation that has characterized the conflict's most intense phases.
Diplomatic Window Remains Narrow
Iran's foreign ministry said regional mediators had drafted proposals seeking to prevent further escalations, while US Secretary of State Marco Rubio said the US remains willing to negotiate. However, both sides continue to signal conditions. Iran's Deputy Foreign Minister Kazem Gharibabadi condemned a reported attack on the under-construction Darkhovin nuclear power plant, and the IRGC has urged Jordan to remove US military bases from its territory.
The 10-day window, if accepted, would represent the first sustained pause in hostilities since the conflict escalated. Traders will watch for official statements from Washington and Tehran in the coming hours for confirmation of whether the proposal gains traction.
