After 110 days of fighting that shook the Middle East and sent global energy markets into turmoil, the United States and Iran have signed a preliminary memorandum of understanding that could end the war. The agreement, signed by President Donald Trump and Iranian President Masoud Pezeshkian, opens the Strait of Hormuz to commercial traffic, offers Iran limited sanctions relief, and creates a two-month window to negotiate a final settlement.
The conflict began in April when Israel and the United States launched strikes on Iranian nuclear facilities, aiming to set back Tehran’s enrichment program. Iran responded with missile barrages, drone attacks on regional shipping, and a blockade of the Strait of Hormuz that disrupted roughly one-fifth of global oil shipments. The resulting spike in energy prices and attacks on commercial vessels pushed the crisis to the top of the international agenda.
What the Memorandum Covers
The memorandum is not a final peace treaty. Instead, it functions as a ceasefire framework with seven core provisions. Both sides agreed to an immediate and permanent halt to military operations on all fronts, including Lebanon, where Iranian-backed Hezbollah has traded fire with Israel. Iran also committed to down-blending its enriched uranium stockpile under supervision from the International Atomic Energy Agency.
On the economic front, Washington agreed to issue waivers for Iranian crude oil exports and related banking services as soon as the document was signed. The Treasury Department is expected to allow limited petroleum transactions to resume quickly, a move that could bring more Iranian barrels back to global markets. However, broader sanctions relief remains tied to a final nuclear agreement.
Perhaps the most closely watched provision concerns the Strait of Hormuz. Iran promised toll-free passage for commercial vessels for at least 60 days, with full restoration of traffic within 30 days. For the first time since the war began, Iranian forces reportedly fired on no vessels in the strait on the eve of the announcement.
Questions That Remain Unanswered
Despite the fanfare, significant gaps remain. Israeli officials were not party to the negotiations, and Israel has reserved the right to retaliate if Hezbollah resumes attacks. That reservation leaves open the possibility that a single border incident could unravel the ceasefire. Regional diplomats privately describe the truce as a pause rather than a durable peace.
The nuclear question is also far from settled. Iranian negotiators had offered to down-blend uranium inside Iran before the war started, but the broader issues of enrichment limits, inspections, and snapback mechanisms remain unresolved. The two sides have 60 days to bridge those differences, with the option to extend the deadline by mutual consent.
Complicating matters further, Iranian negotiator Mohammad Bagher Ghalibaf suggested Tehran may eventually charge transit fees through Hormuz after the 60-day fee-free period. Senior US officials rejected that possibility, saying Gulf states would never accept tolls for access to international waters. The contradiction highlights how much ambiguity still surrounds implementation.
Global Markets Respond Cautiously
Oil prices fell sharply on news of the deal, reflecting relief that one of the world’s most important chokepoints may reopen. Brent crude dropped several percentage points in the hours after the announcement, and shipping insurers began reassessing risk premiums for vessels transiting the Gulf. Still, traders cautioned that any return to pre-war flows will take weeks, and that the final deal could still collapse.
The agreement also carries political implications for Washington. Trump campaigned on reducing American military commitments abroad, and the deal gives him a chance to claim a major diplomatic breakthrough. Critics counter that the oil waivers hand Tehran immediate economic relief before it makes irreversible nuclear concessions, undermining the leverage that sanctions provided.
A Diplomatic Reprieve, Not a Settlement
What happens in the next 60 days will determine whether the memorandum becomes a lasting arrangement or merely a ceasefire that delays renewed fighting. The IAEA must verify Iran’s down-blending claims, negotiators must agree on a nuclear framework, and regional actors must avoid provocations that could spiral out of control.
For now, the Strait of Hormuz is on its way to reopening, and the guns have gone quiet. But the underlying disputes over Iran’s nuclear program, its regional influence, and the security architecture of the Gulf remain unresolved. The world is watching to see whether this fragile truce can hold long enough to become something more permanent.
