Iran's Control Over Hormuz Amid US Talks

Iran Stakes Hormuz Control as US Talks Move Into Nuclear Phase

Ghalibaf's claim that Tehran will "administer" the strait signals a hardening position even as US agrees to lift oil sanctions through August

The Hindu reported on Tuesday that Iran's chief negotiator Mohammad Bagher Ghalibaf declared the Strait of Hormuz will "be administered by the Islamic Republic of Iran, in accordance with international law," signaling that Tehran intends to emerge from negotiations with de facto control over a waterway through which roughly one-third of global maritime oil shipments flow. The statement came hours after the US Treasury issued a 60-day waiver suspending sanctions on Iranian oil through August 21, a major concession intended to reward Iran's agreement to accept IAEA nuclear inspectors and maintain open passage through the straits.

The two moves reveal the fault line now shape negotiations: Iran is securing economic relief and tacit acceptance of its regional dominance, while the US is gambling that minor sanctions relaxation will buy time to lock in a permanent nuclear accord. The gap between those objectives remains vast.

The Hormuz Card Cuts Both Ways

Ghalibaf's claim to administer Hormuz is not merely rhetorical posturing. Iran had announced on Saturday that it was again closing the strait to commercial traffic—the second closure in weeks—arguing that the US and Israel had violated the ceasefire by continuing strikes in Lebanon. The closure immediately reduced shipping traffic, pressed oil prices higher, and reminded the global economy just how much leverage lies in Tehran's hands. When Trump received the warning, he responded with a threat to take over the waterway himself and "possibly charge a toll," according to Fox News.

By Tuesday, a deal had been struck: the US suspended Iran's oil sanctions, and Iran reopened the strait via mutual agreement to establish a direct military communications line to prevent accidents. But Ghalibaf's assertion that Iran will henceforth "administer" the waters reflects Tehran's conviction—probably accurate—that it has won something durable. Iran can now claim it negotiated a return to sovereignty over the strait rather than a reopening imposed by outside force. That framing matters politically at home and strategically in the region.

The economic numbers confirm Iran gained ground. The Treasury waiver permits Iran to sell crude oil at market prices and receive payment in US dollars, a far cry from the black-market shadow-fleet sales Tehran resorted to under full sanctions. Before the war began on February 28, oil had been Iran's lifeline. The temporary relief through August 21 signals the US has made a calculation: keep Iran's economy from collapsing and risk feeding its military machine, or risk a renewed Hormuz closure and global recession.

Where Nuclear Talks Stand

The nuclear dimension remains opaque. Vice President JD Vance announced that Iran had agreed to readmit IAEA inspectors, with work expected to begin within days, reversing the complete halt in international inspections since the US-Israeli air strikes that ignited the war five months ago. Yet The Herald Business reported that some former US Treasury officials close to Iran sanctions see the waiver as premature—sanctions relief is coming before Iran has given up any part of its nuclear program, a reversal of the timeline in the 2015 JCPOA, which required six months of Iranian compliance before sanctions lifted.

The two sides have committed to a 60-day roadmap toward a permanent deal. That deadline—roughly August 22—is when the waiver expires and leverage shifts. If no agreement exists by then, Iran's economy hits a wall, and both sides face a choice between permanent normalization or renewed conflict.

What to Watch

The Lebanon ceasefire holds the key. Israel has made clear it intends to maintain an operational presence in southern Lebanon and preserve freedom to strike Hezbollah. Over 1 million Lebanese have fled their homes since March. If Israel escalates there, Iran sees itself freed from the Hormuz commitments it just made. Trump, meanwhile, has threatened to resume airstrikes if Iran "doesn't behave"—a lever he used successfully to compress the original ceasefire deal in April.

The nuclear endgame arrives in late August. By then, the Strait's status, the terms of IAEA access, and the fate of Iran's frozen assets will have crystallized into either a durable accord or a trigger for the next round of war. Watch for Iran's uranium stockpile claims—it has insisted the enriched uranium will never leave the country, putting it at odds with Trump's stated goal of removing it. That single issue could unravel the entire deal.
