The U.S.-Iran memorandum of understanding has reportedly moved from draft text to an active agreement before the planned Friday signing ceremony in Switzerland, adding a new and messy twist to the Iran crisis.
Axios, citing two U.S. officials, reported Wednesday that the United States and Iran had remotely signed the MOU to end the war and reopen the Strait of Hormuz, and that the agreement is now in effect. Al Jazeera also reported that Iran’s Foreign Ministry and the White House confirmed the document had been signed electronically by President Donald Trump and Iranian President Masoud Pezeshkian.
That matters because, until late Wednesday, the public timeline still pointed to a formal signing in Switzerland on Friday. The new reporting means the 60-day ceasefire and implementation period may already be running, even as the two sides continue sending mixed signals about what exactly happens next.
The deal is active, but the ceremony may still happen
Axios reported that the Friday meeting between delegations led by Vice President JD Vance and Iranian parliamentary speaker Mohammad-Bagher Ghalibaf is still expected to take place. But if the MOU is already in effect, the Switzerland meeting is no longer the starting gun. It becomes the first diplomatic test after implementation has already begun.
That is a serious distinction. A scheduled signing can still fall apart. An active agreement immediately creates obligations, expectations, and potential violations. It also starts the political fight over whether the United States gave up too much to get Hormuz moving again.
The Associated Press reported earlier Wednesday that U.S. officials read the draft memorandum to journalists after days of secrecy. According to AP, the draft requires Iran to at least dilute highly enriched uranium, links U.S. sanctions waivers to the deal, and secures toll-free Strait of Hormuz passage for only 60 days without ruling out future fees.
That last piece is already becoming one of the most sensitive parts of the agreement. The U.S. can claim it forced the strait open. Iran can claim it preserved a path to charge ships later. Shipping companies, insurers, and Gulf energy exporters now have to decide whether a temporary toll-free window is enough to restart normal traffic.
Trump is still keeping the threat of force alive
The agreement also has a hard-edged enforcement problem. CBS News reported that a White House official said the MOU had been remotely signed and was now in effect. But CBS also reported that Trump described the agreement as not final and warned that the United States could resume bombing Iran if Tehran does not “behave.”
That makes the new phase more fragile than the word “deal” suggests. The document may be active, but the core issues are not settled: Iran’s nuclear future, the handling of enriched uranium, sanctions relief, the future of Hormuz fees, Lebanon, and whether Israel accepts the limits implied by the MOU.
For List25 readers, the important update is simple: this is no longer just a leak, draft, or pre-signing drama. The United States and Iran now appear to have activated the MOU ahead of schedule. That raises the stakes immediately because any tanker slowdown, Lebanon strike, uranium dispute, or sanctions fight can now be framed as a test of an agreement already in force.
The Swiss meeting still matters. But the clock may already be ticking.
