**Deck**: Washington says a 60‑day period for its new agreement with Iran begins 18 June, as traffic through the Strait of Hormuz resumes and Saudi tankers move after weeks of going dark. The deal’s architecture ties sanctions relief and oil flows to verifiable nuclear steps, putting tanker crews, Gulf exporters, and global energy buyers inside a high‑stakes countdown.

The latest US–Iran agreement has moved from announcement to implementation, and the clock is now running. US Vice President JD Vance said on 18 June that a 60‑day period tied to the deal’s terms “officially started today,” marking the beginning of a tightly sequenced process that will test whether Tehran is prepared to trade nuclear concessions for economic breathing room and freer energy exports.

Vance described the arrangement as a dial, not a one‑off swap: Iran, he said, has committed to destroy its stockpile of highly enriched nuclear material, and in return the United States has moved to lift what he framed as a blockade in the Strait of Hormuz, restoring the waterway “to where it was before the conflict.” He repeatedly stressed that Iran will only see meaningful benefits if it follows through – arguing that, unlike the 2015 nuclear accord, this deal does not permit enrichment or stockpiling and does not unlock US cash.

On the water, some of the first tangible shifts are emerging. Shipping reports indicate three Saudi oil tankers carrying a combined 6 million barrels of crude transited the Strait of Hormuz after more than two months with their transponders dark. Iranian shipping representatives separately reported that traffic to the country’s southern ports has “normalized” since 17 June, while adding that the Strait remains “under the supervision of the Armed Forces of Iran” and that vessels must continue coordinating with Iranian authorities.

For crews aboard tankers and bulk carriers, the change is immediate and personal. The risk of miscalculation at a narrow chokepoint fringed by patrol boats and missiles is not abstract; it has meant weeks of altered routes, idling vessels, and uncertainty about who is in charge of safety. A reopened strait with clear rules and fewer threats reduces the chance that a routine voyage becomes an incident with potential to spiral.

Vance, defending the deal at a press briefing, argued that critics overstate the economic lifeline it offers Tehran. He said selling “a few million dollars’ worth of oil” would not transform Iran’s economy, and claimed that sanctions had already become largely ineffective at stopping exports, instead pushing transactions into opaque financial channels that Washington could not fully see. The new framework, he contended, focuses on verification of nuclear behavior rather than rhetoric, with the prospect of sanctions snapping back if Iran reverses course after any future relief.

The White House narrative stands in contrast to warnings from opponents who see any easing of maritime pressure or sanctions enforcement as a strategic gain for Tehran and its regional network of partners. They worry that additional oil revenues, even if modest, give Iran more flexibility to fund missile programs or allied armed groups, while a reopened Hormuz reduces immediate leverage the United States and its partners held over a crucial chokepoint.

Beyond the nuclear file, the deal is already bleeding into other fronts. Vance linked the arrangement to expectations on Hezbollah in Lebanon and Israeli operations there, saying Washington expects the group to cease rocket and drone attacks on Israel and for Israel to avoid “going wild in Lebanon.” He also echoed President Trump’s line that Iran will retain only a narrow right to self‑defense and will not be allowed to build out long‑range ballistic missiles under the final settlement, a claim that drew pushback from Israel’s ambassador in Washington.

For energy markets, the reopening of the strait and early signs of resumed tanker flows inject a dose of short‑term relief but also a new layer of uncertainty. OPEC’s secretary general has already dismissed forecasts of an oil supply glut as “critical” in the context of Hormuz’s reopening, signaling that producers will watch how quickly and sustainably Iranian and Gulf exports normalize.

The shareable lesson for policymakers is blunt: Hormuz risk does not require a full blockade to matter – a credible threat of disruption is enough to move ships and markets.

Over the next 60 days, the key indicators will be whether Iran takes verifiable steps to dismantle its highly enriched stockpile, how strictly the US enforces remaining sanctions, and whether any incident at sea challenges the fragile reopening of Hormuz. Traders will track declared and undeclared Iranian export volumes, while regional navies will be watching for any harassment, boarding, or missile activity that could turn this diplomatic countdown into another kinetic crisis.
