Iran accuses US of 3 MOU violations, sets up oversight mechanism for compliance

Iran formally accused the United States of violating three commitments under their war-ending memorandum of understanding and announced a monitoring mechanism to track compliance.

Iran accused the US of violating the memorandum of understanding's Article 1 on ending the Lebanon conflict and announced a monitoring group to review compliance, threatening the fragile détente that has allowed Strait of Hormuz traffic to partially resume.

"The commitments in the MOU form an integrated whole and cannot be viewed separately," said Kazem Gharibabadi, Iran's deputy foreign minister and chief technical negotiator, at a trilateral meeting in Doha on Tuesday.

The Iranian delegation reviewed US military buildup in the region and what it called threatening statements from American officials, Gharibabadi said. The talks, mediated by Qatar and Pakistan, included discussions on partially unfreezing $6 billion in Iranian assets held in Qatar for procurement of essential goods. Three working groups are addressing nuclear issues, diplomacy, and the return of frozen funds, alongside maritime security in the Strait of Hormuz.

The Strait of Hormuz handles about 21 percent of global oil transit, and traffic has already been volatile — 70 vessels crossed on June 25 after the MOU was signed, but that fell to 12 on Sunday after a weekend exchange of strikes. Oil prices edged higher Monday, with Brent crude rising as traders priced in renewed disruption risk.

Monitoring Mechanism Raises Stakes for Compliance

Gharibabadi said Iran would establish a direct communication channel to report and review violations of the MOU, effectively creating an enforcement body outside the agreement's original framework. The mechanism gives Tehran a formal process to escalate grievances rather than resorting to military retaliation, but it also introduces a new point of friction in negotiations that have already stalled.

The US has not responded to Iran's allegations. Vice President JD Vance said Monday that the administration would not accept tolls on the Strait of Hormuz, pushing back on Iranian officials who have insisted the waterway is valuable and that Iran will not give up its rights. "This is not going to end in a place where the Iranians are collecting tolls on ships going through the Strait of Hormuz," Vance said in an interview.

Iran's parliament speaker Mohammad Bagher Ghalibaf struck a different tone Tuesday, saying "passing through the Strait is free of charge only for 60 days" and that Iran would not surrender its rights under any circumstances. The conflicting signals highlight the gap between the two sides as indirect technical talks continue in Doha.

The last time US-Iran tensions escalated to this level, in early 2020 after the killing of Qasem Soleimani, Brent crude spiked more than 5 percent in a single session and the VIX jumped above 18. This time, the stakes are higher: the Strait of Hormuz has been actively mined, and demining responsibilities remain contested. Iran said it alone will clear the mines, rejecting French and Omani offers to collaborate.

For markets, the key risk is a breakdown in the 60-day negotiation window established by the MOU. If the monitoring mechanism produces findings of non-compliance without a resolution mechanism, the path back to open conflict — and a full blockade of the strait — narrows considerably. Moody's Analytics chief economist Mark Zandi estimated the war has already cost American households about $1,000 each in higher fuel and food costs since February.
