US-Iran MOU Reopens Strait of Hormuz Amid Conflicting Traffic Reports

Core Event: Interim Deal and Sanctions Waiver
On June 18 2026 the United States and Iran signed a 14-point memorandum of understanding (MOU) that extends the February cease-fire for 60 days and includes a Treasury-issued waiver allowing Iranian oil to be sold abroad without the “maximum-pressure” sanctions that have been in place for a decade. The agreement is intended to restore free and open transit through the Strait of Hormuz, the narrow Gulf passage that carries roughly 20 percent of global oil and LNG shipments.
Background & Context
The war that began on 28 Feb 2026 after U.S.-Israeli airstrikes forced Iran to close the strait, lay sea mines, and halt most commercial traffic. Daily transits fell from a pre-war average of 130-160 vessels to fewer than 10 ships at the height of the blockade. Over 1,500 vessels were stranded in the Persian Gulf, creating a worldwide energy crunch.
Data & Statistics
- Traffic counts: U.S. Central Command (CENTCOM) reported 55 merchant ships (? 17 million bbl) transiting on 20 June, while commercial tracker Kpler logged only 20 ships and Windward recorded 12 ships on 19 June.
- Pre-war baseline: ? 130 ships/day.
- Oil price moves: Brent fell to $74 /barrel on 19 June, rose to $81 by 22 June, then settled near $80 as markets reacted to mixed traffic signals.
- Iranian exports: Three U.S.–sanctioned supertankers (Elva, Virgo, Vigor) moved ? 6 million bbl through the strait on 19 June; Iranian officials claim > 25 million bbl have crossed since the waiver.
Official Statements & Responses
- Scott Bessent (U.S. Treasury): announced Iran’s “commitment to free and open transit” and framed the waiver as a confidence-building step.
- Chris Wright (U.S. Energy Secretary): said oil and gas flows have “already returned to normal” and that prices will keep falling, citing rising U.S. and Venezuelan production.
- CENTCOM: asserted “safe passage remained intact” and highlighted the 55-ship count.
- Iranian Foreign Ministry (Esmaeil Baghaei): reported a “mechanism” for safe passage was established in Swiss talks.
- President Donald Trump: pledged no tolls during the 60-day period but warned of “harder” strikes if Iran breaches the cease-fire.
Criticism & Opposition
Shipping insurers and major underwriters (Lloyd’s of London, Chubb) refuse to honor Iran’s proposed insurance-fee regime, calling it “unworkable” and a sanctions trap. Industry groups (BIMCO, INTERTANKO) warn that the dual-route system—an Iranian-controlled northern corridor and a U.S.–backed southern lane—creates legal uncertainty and could force vessels to pay “state-sponsored extortion tolls.” Mine clearance remains incomplete; experts estimate 80 mines must be removed before the central traffic separation scheme can be used safely.
Conflicting Reports & Gaps
- Ship counts: CENTCOM’s 55 vs. Kpler’s 20 vs. Windward’s 12 illustrate divergent methodologies (military radar vs. AIS data).
- AIS usage: A growing share of vessels travel “dark,” disabling transponders, which inflates military counts but depresses commercial datasets.
- Transit rules: Iran’s Persian Gulf Strait Authority (PGSA) demands permits and reserves the right to impose insurance fees, while the U.S. Navy’s Joint Maritime Information Center (JMIC) advises voluntary coordination on the southern corridor. No joint verification mechanism has been publicly detailed.
Verbatim Quotes
- “The key point is not that traffic stopped, but that traffic continued while using less standard/less transparent routing,” — Kpler
- “I'm long out of the business of predicting oil or gasoline prices, but they will continue to head down.” — Chris Wright, U.S. Energy Secretary
- “no vessel is permitted to pass through the Strait of Hormuz without a valid passage permit issued by the PGSA” — Persian Gulf Strait Authority
- “What is beyond dispute, however, is that Iran has demonstrated an ability to significantly affect shipping through the Strait of Hormuz.” — Daniel Shapiro, Atlantic Council
- “The market’s expectation of the opening of the Strait has been premature,” — Saul Kavonic, MST Marquee
Why It Matters / Impact
The strait’s partial reopening has already eased crude shortages, allowing Brent to retreat from $150-plus spikes projected under a prolonged closure. Yet lingering uncertainty fuels price volatility, influences G7 decisions on Russian sanctions, and preserves Iran’s leverage over global energy markets.
What’s Next
Negotiators in Bürgenstock, Switzerland, will refine the “safe-passage mechanism,” address mine-clearance responsibilities, and decide whether Iran’s toll proposal survives beyond the 60-day window. Industry analysts project that full normalization of vessel flows will take months, not weeks, as insurers, ports, and shipowners adjust to the dual-route regime and lingering security risks.
