Tentative 60-day Iran ceasefire deal awaits Trump approval

Lead: U.S. officials say negotiators have reached a tentative memorandum of understanding that would extend the current U.S.–Iran ceasefire for 60 days and open talks on Iran’s nuclear program, but the agreement remains subject to President Trump’s approval. The development came amid renewed U.S. strikes, Iranian retaliatory claims, and intensified diplomacy involving Pakistan and other regional actors on May 28, 2026. U.S. sources told the White House press pool the MOU is done in principle, but language points are still being negotiated and Tehran has not publicly signed off on the latest text. Senior U.S. officials and regional partners are meeting in Washington and elsewhere as military, economic and political pressures continue to shape the bargaining environment.

Key Takeaways

• A tentative 60-day memorandum of understanding (MOU) to extend the ceasefire and restart nuclear talks has been reported by U.S. sources; the deal is pending President Trump’s approval (May 28, 2026).
• Vice President JD Vance said negotiators have “made a lot of progress” but that it is “still TBD” whether the president will sign the MOU.
• The U.S. Treasury on May 28 sanctioned firms tied to Iran’s military-linked petroleum exports and designated Iran’s Persian Gulf Strait Authority, expanding economic pressure.
• U.S. Central Command denied Iranian state-media claims that a U.S. aircraft was shot down near Bushehr and confirmed all U.S. air assets accounted for.
• Lloyd’s List Intelligence reported Iran-linked vessels accounted for roughly 50% of known Strait of Hormuz traffic recently, while weekly transits remain down about 46% from pre-war averages.
• Human rights groups report a 139% increase in executions of political prisoners in Iran this year, with at least 43 executions recorded in 2026 so far.
• Pakistan is facilitating indirect U.S.–Iran talks; Pakistani Foreign Minister Ishaq Dar met Secretary of State Marco Rubio in Washington on May 29, 2026, to review developments.
• Regional clashes continued: Iran launched missiles or drones in reported retaliation for U.S. strikes; Kuwait intercepted at least one missile on May 27–28, and Israel expanded operations in southern Lebanon.

Background

The current diplomatic push follows weeks of tit-for-tat military actions, a U.S. naval blockade announced on April 13, 2026, and a declared ceasefire that has been fragile since early April. Both Washington and Tehran have signaled an interest in halting direct combat and returning to talks, but each side has tied de-escalation to strict political and security conditions: the U.S. insists on limits to Iran’s nuclear capabilities and relinquishment of enriched uranium, while Iran seeks guarantees on sanctions relief and regional security commitments. Pakistan has emerged as an intermediary, relaying framework proposals between capitals and arranging meetings among senior officials.

Economic pressure has been a central tool for the U.S. administration. The Treasury Department has targeted entities it says enable Iran’s military-controlled petroleum exports and has warned companies against paying newly announced Iranian tolls for passage through the Strait of Hormuz. The strait’s closure or restricted access would threaten global energy markets; shipping patterns and so-called “dark transits”—vessels switching off tracking systems—have increased as commercial operators try to navigate sanctions risk, insurance complications and rising military danger.

Main Event

On May 28, 2026, U.S. sources briefed the White House press pool that negotiators had reached a provisional 60-day memorandum of understanding to extend the ceasefire and open formal talks on Iran’s nuclear program. Officials described remaining work on wording and mechanisms: negotiators were “going back and forth” on language points, and President Trump’s endorsement remained uncertain. Vice President JD Vance said the teams had “made a lot of progress” but that it was still unclear when or if the president would sign the MOU.

Diplomatic activity intensified in Washington. Secretary of State Marco Rubio met Pakistan’s Foreign Minister Ishaq Dar, who had been instrumental in shuttling proposals between the two governments. Pakistani officials characterized the meeting as a review of bilateral relations and an exchange of views on regional developments; Pakistani mediation has been key to multiple iterations of a framework that aims to reopen the Strait of Hormuz and restart direct negotiations.

At the same time, military incidents and reciprocal strikes complicated the picture. CENTCOM said it intercepted multiple Iranian drones near the Strait of Hormuz and later denied Iranian state TV’s claim that a U.S. aircraft had been shot down near Bushehr. Iran’s Islamic Revolutionary Guard Corps (IRGC) reported retaliatory strikes on U.S. positions and said it detained or turned back several commercial vessels attempting to enter the Persian Gulf—claims that U.S. officials disputed or characterized differently.

Economically, the Treasury’s May 28 sanctions targeted Hong Kong-based firms and eight vessels accused of helping Iran’s military-linked petroleum exports reach buyers. Treasury Secretary Scott Bessent framed the move as restricting Tehran’s ability to fund military programs and proxies. Meanwhile, regional dynamics grew more fraught: Israel expanded operations in southern Lebanon, and Gulf states, including Kuwait, reported interceptions of missiles and projectiles linked to Iranian actions.

Analysis & Implications

If the 60-day MOU is signed by President Trump, it would buy time for structured negotiations on Iran’s nuclear program and potentially reduce immediate military escalations by providing a formal window for talks. A short-term, binding cessation of hostilities could calm shipping lanes enough to reduce insurance and rerouting costs, but progress depends on technical verification steps, timelines for uranium transfers or dismantling of specific capabilities, and enforceable monitoring—areas that diplomats say are the hardest to lock down.

U.S. domestic politics and presidential prerogatives add uncertainty. The MOU, by definition, would not be a final treaty; its acceptance hinges on the president’s judgment about whether the language meets U.S. “red lines,” as senior officials repeatedly emphasized. That gives the president leverage to reject terms at the last minute, which in turn raises the risk that Tehran will perceive American offers as unreliable and either re-escalate militarily or seek asymmetric counters in the region.

Sanctions and maritime interdiction continue to be central tools for U.S. strategy. Recent Treasury designations aim to choke revenue routes for Iran’s military-linked petroleum operations; if effective, they could accelerate Tehran’s willingness to compromise—but they could also incentivize covert shipping practices, increased use of third-party intermediaries, or closer economic coordination with China and other partners. Lloyd’s data showing high proportions of Iran-linked traffic and a sharp dip in weekly transits demonstrate how economic and security measures ripple through global supply chains.

Human rights and humanitarian consequences complicate the diplomatic ledger. Reports of a large uptick in executions in Iran and the displacement of hundreds of thousands in Lebanon underscore domestic and regional costs not easily fixed by a temporary MOU. Any credible long-term settlement will need parallel tracks for human-rights monitoring, reconstruction assistance in affected areas, and confidence-building measures to prevent localized violence from unraveling broader agreements.

Comparison & Data

These numbers underline how the crisis combines military, economic and humanitarian pressures. The maritime data show how fragile global shipping remains; the human-rights figures illustrate parallel domestic repression that could influence Tehran’s negotiating posture.

Reactions & Quotes

U.S. officials stressed progress but cautioned the deal was not yet finalized.

“We’re not there yet, but we’re very close, and we’re going to keep on working at it.”

Vice President JD Vance

Vance tempered optimism with a reminder that final approval depends on the president and on unresolved language points between delegations.

“The teams have been going back and forth. Again, everything depends on what the president wants to do.”

Treasury Secretary Scott Bessent

Bessent framed sanctions as a lever to strengthen U.S. negotiation posture and insisted Washington would not accept what he called a “bad deal” for Americans.

“Nobody’s going to control [the Strait of Hormuz]… Oman will behave just like everybody else or we’ll have to blow them up.”

President Donald Trump

President Trump’s remarks about Oman drew sharp regional reactions and prompted U.S. officials to clarify diplomatic outreach to Gulf partners. Iranian officials condemned the threat and framed U.S. statements as evidence of aggressive posture that undermines regional stability.

Unconfirmed

• Whether President Trump will approve and sign the 60-day MOU—U.S. officials say it is pending his decision and final language clearance.
• Tehran’s formal acceptance of the latest MOU text—reports indicate Iran has not publicly confirmed the newest draft.
• Claims by Iranian state media that two commercial ships were detained near Bandar Abbas and that U.S. strikes hit “empty areas”—these assertions conflict with U.S. military accounts and remain independently unresolved.

Bottom Line

The reported 60-day MOU would be a pragmatic, short-term step to stabilize hostilities and open a pathway to nuclear negotiations—but its practical value depends on verification, the durability of economic pressure, and whether President Trump signs the text. Even if Washington and Tehran accept the framework, many technical details remain, and either party can still withdraw or renege on commitments absent robust monitoring and third-party oversight.

Beyond the immediate political calculus, the outcome will affect global markets, regional alliances and humanitarian conditions. A signed and enforced MOU could reduce the likelihood of near-term naval clashes and lower shipping costs; a collapsed deal could accelerate military escalation, deepen sanctions-driven economic distress in Iran, and further destabilize neighboring states already strained by displacement and conflict.
