The United States has lifted its naval blockade of Iranian ports and coastlines, marking the start of a 60-day negotiation period aimed at reaching a final deal on Iran's nuclear program and regional security. The move follows the signing of a 14-point memorandum of understanding (MOU) between Washington and Tehran on Wednesday, which includes the reopening of the Strait of Hormuz to commercial traffic.
US Central Command announced the end of the blockade via social media, stating that US naval assets will remain in the Middle East to ensure compliance with the agreement. The Combined Maritime Force’s Joint Maritime Information Center has reduced the security threat level in the Strait of Hormuz from "critical" to "moderate," though mariners are advised of potential mines and congestion as clearance operations continue. Ships are recommended to use the southern route through Omani waters for safe passage.
Under the MOU, the blockade must fully end within 30 days, and Iran is required to demine and remove military obstacles within the same period. The agreement also stipulates that Iran will not charge vessels for passage through the strait during the 60-day negotiation window, reversing its previous practice of levying fees. The fifth point of the MOU guarantees safe passage without charge, although it remains unclear whether ships must still provide ownership or other information to Iran's Persian Gulf State Authority.
US President Donald Trump celebrated the deal on social media, writing, "OIL IS FLOWING, IRAN CAN NEVER HAVE A NUCLEAR WEAPON," and expressing hope for a ceasefire "on all fronts," including between Israel and Hezbollah in Lebanon. Vice-President JD Vance emphasized that Iran will not receive any funds unless it meets its obligations under the agreement. The formal signing ceremony scheduled for Switzerland has been postponed, though US officials plan to travel there for talks at an uncertain time.
Iran's Supreme Leader Mojtaba Khamenei stated that he initially disagreed with the deal but ultimately allowed it to proceed, asserting that Trump came to the agreement "out of desperation." Iranian President Masoud Pezeshkian praised the nation's diplomacy and "resilience," saying Iran "did not trade its dignity" in the negotiations. Both sides now enter the 60-day period to finalize a comprehensive agreement, with discussions ongoing about the future administration of the Strait of Hormuz involving Oman, Iran, and other Gulf states.
Why This Matters
This development directly affects global oil prices and maritime security in the Strait of Hormuz, a critical chokepoint for 20% of the world's petroleum trade. For energy traders, shipping companies, and policymakers, the 60-day window provides both opportunity and uncertainty: the reopening of the strait could lower shipping insurance and fuel costs, but potential mines and congestion remain risks. The agreement also tests whether diplomatic negotiations can prevent further escalation in the Middle East, with implications for regional stability and nuclear nonproliferation.
