• Iran says it will return to the June U.S.-Iran memorandum of understanding (MoU) if Washington first resumes its commitments, framing the statement as a conditional opening rather than a rejection.
  • The latest exchange of attacks, including U.S. strikes on Iran's Larak Island and Iranian missiles at U.S. bases in Jordan, has escalated tensions and sharply reduced shipping through the Strait of Hormuz.
  • The dispute over the MoU's ambiguous wording on Hormuz control, combined with U.S. pressure tactics, leaves the region on a knife's edge, with energy markets and global consumers vulnerable to further disruption.

A Conditional Opening, Not a Clean Rejection

Iran's position is best read as a conditional opening rather than a clean rejection: Tehran says it will return to the June U.S.–Iran memorandum of understanding only if Washington first resumes its own commitments. At the Shanghai Cooperation Organisation summit in Bishkek on September 1, President Masoud Pezeshkian said Iran would “immediately reciprocate” if the United States returned to its obligations under the June MoU. He also said war serves no one’s interests and left open the possibility of a negotiated outcome.

The remarks came after the first direct exchange between the sides in more than a month. The United States struck targets on Iran’s Larak Island, saying it targeted rocket launchers allegedly intended to deploy sea mines in Hormuz; Iran then fired missiles at two U.S. bases in Jordan. Jordan reported intercepting eight missiles.

Hormuz Shipping Plummets, Energy Markets Jittery

The Strait of Hormuz, a major oil-export corridor, has seen its operation impaired, with shipping traffic drastically reduced. One recent assessment put traffic at roughly seven vessels daily during the war, versus about 100 per day beforehand; separate Kpler data cited by CNBC showed only five crossings on one recent Tuesday compared with about 130 daily before the conflict. This constrained passage raises freight, insurance, and energy-supply risks for oil-importing countries and producers whose exports move through the Gulf, creating volatility in crude markets even when prices briefly move lower on hopes of a partial reopening.

U.S. policy has moved toward an “economic D-Day” pressure campaign: Treasury Secretary Scott Bessent announced measures targeting Iranian revenue streams, including oil, and said 60 entities had been sanctioned for allegedly facilitating Iranian oil sales. The U.S. has also threatened secondary sanctions against foreign countries and firms doing business with Tehran. CNBC reported late-August benchmark prices of about $89.63 per barrel for October Brent and $83.11 for October WTI, while traders monitored crude flows through Hormuz. These figures are a snapshot, not a forecast.

The Core Dispute: The June MoU's Ambiguity

The dispute centers on the June MoU, not a fully settled peace treaty. It was intended to support a ceasefire and create a 60-day window for wider negotiations on ending the conflict and Iran’s nuclear program. The agreement unraveled quickly amid disagreements over how it should be implemented, particularly the ambiguous wording on control and administration of the Strait of Hormuz. Each side accused the other of violating it.

Iran says renewed diplomacy requires Washington to demonstrate trust, respect Iranian rights, ease pressure, and honor previous commitments. Foreign Minister Abbas Araghchi has said restarting diplomacy is “not impossible,” but that pressure will not succeed. The U.S. administration has publicly said it is not seeking talks at present. This divergence explains why Iran’s “return to the MoU” language is politically significant but unlikely, by itself, to restart negotiations.

Tehran has broadened the issue beyond its bilateral dispute with Washington. Senior Iranian security official Mohsen Rezaei has linked any Hormuz understanding to an end to war in Gaza, Israeli withdrawal from Lebanon, and a halt to attacks in Syria—conditions that make a narrow maritime agreement harder to achieve. Oman, Qatar, Pakistan, and other regional actors have been involved in efforts to lower tensions. Oman and Iran have discussed a temporary shipping route and mine-clearance arrangement, while Pakistan has sought to encourage a return to negotiations.

Economic and Human Toll Across the Region

The prolonged sanctions, currency pressure, disrupted commerce, infrastructure damage, and lack of investor confidence weigh most directly on Iranian households and firms. A credible de-escalation could reduce these pressures, although sanctions relief would depend on implementation rather than rhetoric alone. Escalation raises security risks around military facilities, ports, airports, and energy infrastructure across the region, as illustrated by Iran’s strike on sites in Jordan after the Larak attack. Global consumers and industry face risks that disruptions at Hormuz could feed through into fuel prices, transportation costs, petrochemicals, shipping insurance, and broader inflation—especially for countries dependent on Gulf oil and liquefied natural gas.

Shipping firms, insurers, and oil traders operate in an unpredictable environment. Iran says only limited and temporary transit is allowed; U.S. Central Command says it has facilitated significant commercial flows and describes shipping lanes as open. The contrast underscores the difficulty of verifying access and safety conditions in real time. The central debate in policy circles is whether periodic U.S. military strikes and sanctions can compel concessions, or instead make a wider regional war and durable shipping disruption more likely. Iranian leaders frame pressure as counterproductive, while the U.S. frames it as leverage against Tehran’s military and economic capacity.

What to Watch Next

The present crisis grew out of the U.S.–Israeli military campaign against Iran that began on February 28, followed by a ceasefire phase and then the June interim MoU. That framework collapsed over competing interpretations, after which U.S. strikes resumed in July and Iran retaliated against U.S. interests and regional infrastructure.

Analysts quoted by Al Jazeera caution that a strategy of intermittent strikes could become a de facto permanent conflict rather than a route to settlement. Trita Parsi of the Quincy Institute characterized periodic bombing as “forever war,” while analyst Negar Mortazavi argued that mutual return to the MoU remains the clearest route to de-escalation—but warned that every new exchange risks a wider regional conflict.

The practical takeaway is that Pezeshkian’s statement is diplomatically softer than an outright refusal, but it does not signal an imminent agreement. Both sides are tying any return to negotiations to prior concessions by the other, and the latest military exchange makes miscalculation around Hormuz the most immediate risk.
