The United States and Iran are set to sign a 60-day interim peace agreement this Friday in Switzerland, marking a potential turning point after four months of military conflict. The International Energy Agency reports that global oil supply in 2026 is projected to fall by approximately 3.9 million barrels per day on average. This severe deficit has overwhelmed demand forecasts through at least the third quarter.
Markets responded immediately to the diplomatic breakthrough. Brent crude dropped roughly 4% to around $84 per barrel, retreating significantly from the near-$120 highs recorded during the peak of the crisis. This represents a $36 per barrel swing in mere months as traders price in reduced geopolitical risk.
The conflict began on February 28, 2026, when joint US-Israel air strikes triggered supply disruptions across the Persian Gulf. The most critical impact was the closure of the Strait of Hormuz, which transports approximately 20% of the world’s oil. Production losses were concentrated among Gulf producers within the conflict zone, driving the historic supply decline cited in the IEA’s May 2026 Oil Market Report.
The upcoming formal signing aims to halt hostilities and restore transit through the Strait of Hormuz. This 60-day framework serves as a confidence-building measure rather than a permanent settlement. Investors should note that while prices have cooled, they remain elevated above pre-conflict levels due to unresolved nuclear concerns.
Market participants are now focused on the IEA’s June Oil Market Report for updated post-deal projections. If the agency signals narrowing supply deficits in the second half of 2026, crude prices could face further downward pressure. The spread between current valuations and crisis peaks represents tens of billions of dollars in global economic activity hanging in the balance.
