The United States and Iran are expected to sign a memorandum of understanding on June 19 at Switzerland’s Burgenstock resort, a development that would mark the most significant diplomatic breakthrough between the two nations in decades.

The 14-point draft MOU covers an immediate ceasefire, the reopening of the Strait of Hormuz to toll-free shipping, and the lifting of the US naval blockade on Iranian ports. It also establishes a 60-day negotiation window focused on Iran’s nuclear program, with potential sanctions relief tied to inspection measures.

What’s in the deal

The fighting traces back to US-Israeli strikes around February 28, 2026, which triggered an escalating cycle of military responses across the Middle East.

The Strait of Hormuz, a narrow waterway through which roughly a fifth of the world’s oil supply passes on any given day, has been a flashpoint throughout the conflict.
