The U.S.-Iran conflict has moved into a critical implementation phase following a preliminary memorandum of understanding. A 60-day timeline is now active for Washington and Tehran to finalize a formal treaty, with back-channel negotiations intensifying in Switzerland. President Trump has signaled a major shift by agreeing to submit the final deal for Congressional review, while Vice President JD Vance indicated that the framework's text could be released as early as this week. While energy markets have responded positively with a rapid decline in oil prices and the issuance of immediate oil sanctions waivers for Tehran, new friction points have emerged over the Strait of Hormuz. Despite U.S. claims of a 'toll-free' passage, Iranian state media and the Ministry of Foreign Affairs have announced plans to charge maritime fees in coordination with Oman. This development, alongside a 15-week supply disruption ending this Friday, has stabilized global oil futures but introduced new economic complexities to the maritime agreement. Regional tensions remain a significant hurdle to long-term stability. Israel has issued a 'hard response' warning regarding Iran's activities in southern Lebanon, asserting that the maritime deal fails to address regional proxy conflicts. Domestically, President Trump has expressed high confidence that the framework will permanently prevent Iran from obtaining nuclear weapons. However, the U.S. continues to push for a total nuclear ban while Tehran negotiates for a 'cap' on research, and the White House has reportedly kept military options on the table should diplomatic efforts fail.
