The United States and Iran signed an interim memorandum of understanding on Thursday, June 18, 2026, to extend a cease-fire and reopen the Strait of Hormuz.
The agreement aims to stabilize global financial markets by reducing oil-shipping risk premiums and ensuring the safe movement of energy supplies through one of the world's most critical maritime chokepoints.
The 14-point memorandum establishes a 60-day extension of the current cease-fire [1]. Under the terms of the deal, passage through the Strait of Hormuz will be toll-free for the duration of this 60-day period [1].
Officials said they intend to restore normal traffic levels within the Strait over the next 30 days [1]. This timeline is designed to gradually ease the logistical bottlenecks caused by previous hostilities and the closure of the waterway.
Market participants said the announcement has already begun to soothe investor anxiety. The move is expected to lift equities and lower the volatility associated with energy transport in the region [2].
The deal focuses on ending immediate hostilities and restoring the flow of commerce. By removing the threat of sudden closure or seizure of vessels, the U.S. and Iran seek to neutralize the geopolitical tension that has driven up global energy costs.
While the agreement is interim, it provides a window for further diplomatic negotiations regarding sanctions, and nuclear terms [1]. The immediate priority remains the physical security of the shipping lanes and the stabilization of the global economy [2].

This interim agreement serves as a tactical decompression valve for global energy markets. By guaranteeing toll-free passage and a short-term cease-fire, the two nations are prioritizing economic stability over immediate political resolution. The 60-day window creates a critical period of market certainty, though the long-term stability of the region depends on whether this MOU leads to a more permanent treaty regarding nuclear proliferation and sanctions.
