President Trump announced on June 15 that a preliminary memorandum of understanding to end the US-Iran conflict has been signed. The document, electronically signed by Trump, Vice President JD Vance, and Iranian Parliament Speaker Mohammad Bagher Ghalibaf, covers a ceasefire extension, the reopening of the Strait of Hormuz to commercial shipping, and a cessation of hostilities that have spread into Lebanon.

Trump called the MoU “complete” and said the Strait of Hormuz would begin partially reopening immediately. A formal signing ceremony is scheduled for Friday in Switzerland, where Vance is expected to attend.

Bitcoin and other major digital assets rallied on the news, with investors interpreting the agreement as a meaningful reduction in geopolitical risk.

What’s actually in the deal

The core details of the agreement remain undisclosed. What we do know is that the MoU builds on a 60-day deadline Trump set in 2025, which came and went without resolution. The new framework establishes another 60-day ceasefire window intended for continued negotiations on Iran’s nuclear program and potential sanctions relief.
