Iran Says US Memorandum of Understanding Is Being Finalized

Iran has signaled that the long-rumored memorandum of understanding with the United States is in the final stages, with officials pointing to a signing ceremony in Switzerland later this week. The framework would end active hostilities, reopen the Strait of Hormuz, and start a 60-day clock on broader nuclear and sanctions talks.

What Iran is saying

Iran’s Deputy Foreign Minister Kazem Gharibabadi announced that the text of a memorandum of understanding between Iran and the United States has been finalized and will be officially signed on Friday in Switzerland.

Gharibabadi said intensive negotiations have been underway in recent weeks with mediation by Pakistan and Qatar, with the latest round in Tehran lasting more than 14 hours. Iran’s final amendments were accepted, completing the document now being referred to as the “Islamabad Memorandum of Understanding.”

What is actually in the deal

Vice President JD Vance described the memorandum as “about a page and a half” long, calling it a broad framework that leaves details to be worked out during future technical negotiations. Vance also told NBC News that international nuclear inspectors will be allowed back into Iran under the terms of the MOU.

The agreement provides for an end to military strikes, the reopening of the Strait of Hormuz to commercial shipping, an end to the US naval blockade of Iranian ports, and a 60-day extension of the ceasefire. Major issues remain unresolved, with no accord yet on Iran’s nuclear program, uranium stockpiles, or sanctions relief.

Why traders care

The Strait of Hormuz handles a large share of global seaborne crude. President Trump authorized the toll-free opening of the Strait of Hormuz and the immediate removal of the US Naval blockade, telling “ships of the world” to start their engines and let the oil flow.

That has direct implications for crude pricing, tanker rates, and the defense complex that has been bid on Middle East risk. Mehr also reported that oil and some financial sanctions on Iran will be lifted, and that the US and allies will submit plans for reconstruction.

What could still derail it

Iranian President Masoud Pezeshkian said the framework represents an important step toward ending the war and beginning negotiations, but stressed that a final agreement has not yet been completed. Hardliners in Tehran have already pushed back on the public messaging around the deal.

The memorandum leaves key issues unresolved, giving the two sides 60 days to resolve what to do about Iran’s stockpile of highly enriched uranium and its nuclear program, according to Iranian state media. Any slippage during that window could put risk premium right back into oil and defense names. See other news for the latest developments.

Options market and stocks to watch

Watch for a continued unwind of the geopolitical risk premium across energy and defense, with crude-linked names and shipping the most sensitive to the Hormuz reopening.

• USO: watch for pressure if the Strait of Hormuz reopens cleanly and sanctioned Iranian barrels return to market.
• XOM: watch for crude-price sensitivity; a softer geopolitical bid in oil typically weighs on majors.
• LMT: watch for defense names to fade Middle East risk premium if the ceasefire holds.
• RTX: watch for similar positioning shifts tied to reduced regional escalation risk.
• SPY: watch for broad risk-on follow-through if the Friday signing in Switzerland goes ahead without incident.
