President Donald Trump digitally signed a memorandum of understanding with Iran on June 15, 2026, kicking off 60 days of technical negotiations over Tehran’s nuclear program and dangling the prospect of sanctions relief. Bitcoin, Ethereum, and a broad basket of altcoins surged almost immediately.
The MOU, co-signed alongside Vice President JD Vance and Iranian parliamentary speaker Mohammad Bagher Ghalibaf, extends an existing ceasefire and commits both sides to reopen the Strait of Hormuz to toll-free shipping by June 19. A formal signing ceremony is scheduled for the same date in Geneva.
What the deal actually says, and what it doesn’t
The memorandum sets up a framework. The hard questions, uranium enrichment levels, stockpile limits, frozen asset releases, and the scope of any sanctions rollback, are all punted to a new round of talks that will unfold over the next two months.
Sanctions relief is explicitly conditional. Iran has to demonstrate compliance with nuclear commitments and maintain what the White House describes as a “cooperative regional posture.”
