Fresh tensions have emerged between the United States and Iran over the future management of the strategically vital Strait of Hormuz, despite the recent signing of a memorandum of understanding aimed at ending months of conflict. US President Donald Trump stated that Washington retains the ability to quickly reimpose a naval blockade in the waterway if Iran fails to comply with the terms of the newly agreed roadmap, while Iranian officials insisted the strait will operate under Tehran’s authority.

Speaking during an executive order signing ceremony at the White House, Trump argued that the blockade imposed during the conflict had a greater impact on Iran than military strikes. He claimed the restrictions effectively halted Iranian shipping activity and warned that the United States could restore the blockade within minutes if necessary. Trump also stressed that Washington would closely monitor Iran’s conduct during the implementation of the agreement and would respond firmly to any perceived violations.

The US president said relations would remain stable as long as Iran complied with its commitments and demonstrated respect for the agreement. However, he reiterated that the administration was prepared to take action if Tehran failed to meet its obligations. His comments highlighted lingering mistrust between the two countries despite recent diplomatic efforts to reduce tensions and prevent further escalation in the region.

Iranian leaders offered a contrasting view regarding control of the waterway. Iranian Parliament Speaker Mohammad Bagher Ghalibaf said the Strait of Hormuz would be managed by Iran in accordance with Iranian laws and frameworks. Speaking to state media following discussions in Switzerland, Ghalibaf emphasized that the management of the strait would not return to pre-war arrangements and would instead operate under mechanisms established by Tehran.

Iran also announced plans to establish a coordination centre and a dedicated hotline to address any incidents or disputes that may arise during the implementation period. According to Iranian officials, the communication channel is intended to ensure quick resolution of operational issues and support stability in regional trade and energy markets. The measures form part of broader efforts to maintain confidence following the recent agreement between Washington and Tehran.

The Strait of Hormuz remains one of the world's most important maritime chokepoints, carrying roughly one-fifth of global oil and gas supplies. Under the recently signed memorandum of understanding, the naval blockade was lifted, commercial shipping resumed, and certain restrictions on Iranian oil exports were temporarily eased. However, the differing statements from US and Iranian leaders underscore the fragile nature of the agreement and suggest that control of the strategic waterway will remain a key issue in future negotiations between the two countries.
