Historic Iran-US Agreement; Trump: Strait of Hormuz to Open Friday

Signing of Peace Memorandum and End of Hostilities In a major diplomatic breakthrough that impacted global markets today, June 16, 2026, U.S. President Donald Trump announced the formal signing of a Memorandum of Understanding (MOU) with Iran. The agreement, signed electronically, marks the end of 107 days of military conflict and intense tension in the Persian Gulf region [1]. According to published reports, the document was signed by Donald Trump, JD Vance (U.S. Vice President), and Mohammad Bagher Qalibaf, Speaker of the Parliament and Iran's chief negotiator [3].

Reopening the Strait of Hormuz and Energy Market Impact One of the most critical clauses of this agreement is the full reopening of the Strait of Hormuz. Trump emphasized in his remarks that this vital waterway will be completely open for commercial shipping by Friday (June 19) [2]. He noted that tankers have already begun moving through a secure "Southern Highway." This news immediately caused oil prices to drop by 4 to 5 percent in global markets, while Wall Street indices reached new record highs [5].

Party Commitments and Role of International Mediators Within the framework of this agreement, Iran has committed to not pursuing nuclear weapons, and in exchange, the United States will lift the naval blockade of Iranian ports [1]. It has also been scheduled for an official signing ceremony to take place this Friday in Geneva, Switzerland, to release more details of this 60-day agreement [8]. Turkey, Qatar, and Pakistan have been praised as the primary mediators in achieving this diplomatic solution [7].

Remaining Challenges: Right of Passage and Inspections Despite initial optimism, reports indicate some differences in the interpretation of the agreement's clauses. While American officials emphasize toll-free passage for ships, media outlets close to Iran have stated that Tehran intends to reserve the right to collect maritime service fees after a 60-day period [4]. Additionally, the final status of the nuclear program and Iran's frozen assets will be reviewed in technical negotiations in the coming weeks [9].
