U.S.–Iran Deal to End Hostilities and Reopen the Strait of Hormuz
6/16/2026, 5:59:27 AM
The Agreement and Immediate Terms
The United States and Iran announced a memorandum of understanding (MoU) that will be signed in Switzerland on Friday. The framework extends the cease-fire between the parties for 60 days, lifts the U.S. naval blockade of Iranian ports, and calls for a “toll-free” reopening of the Strait of Hormuz for that period. Iranian Deputy Foreign Minister Kazem Gharibabadi said the deal “immediately ends the war” and that the text will be released after the signing ceremony. U.S. Vice President JD Vance told CNBC the expectation is that the strait will remain toll-free in the long term.
Background to the Standoff
Hostilities began on 28 February 2026 after U.S. and Israeli strikes on Iranian nuclear and missile facilities. In retaliation Iran closed the Hormuz channel, which before the war carried about 20 percent of global oil and natural gas shipments. The United States responded with a blockade of Iranian ports. The closure reduced daily transits from roughly 135 to a fraction of that level and stranded an estimated 600 vessels—about 300 fully loaded tankers in the Persian Gulf and another 250 empty tankers awaiting loading.
Scale of the Shipping Backlog
Kpler data indicate 118 tankers could exit the Gulf within 15 days once the backlog clears. At the time of reporting, 300 fully loaded vessels and 250 empty vessels were waiting in the Gulf, while 500 commercial ships remained trapped overall. Analysts at Kpler projected that daily transits could rise to 40 per day, roughly 50 percent of pre-war levels, within the first month of implementation.
Why the Strait Matters
The waterway is a critical conduit for energy markets; its closure drove Brent crude from $70 to a peak above $120 per barrel and lifted West Texas Intermediate to similar highs. After the deal was announced, Brent fell 4-5 percent to about $83 and WTI to $81. Market participants expect the risk premium to recede gradually, but full normalization of oil flows is projected to reach 80 percent of pre-war levels by the end of Q3 2026, according to Capital Economics. Persistent challenges—mine clearance, high war-risk insurance (1-4 % of vessel value per transit versus <0.1 % pre-war), and damaged production facilities—mean price relief will be incremental.
Official Statements & Responses
- President Donald Trump posted on Truth Social: “Ships of the World, start your engines. Let the oil flow!” and affirmed the “toll-free opening” of Hormuz.
- Iran’s Deputy Foreign Minister Kazem Gharibabadi confirmed the agreement and the immediate cessation of hostilities.
- The United Kingdom, France, Germany and Italy issued a joint statement urging rapid, unrestricted reopening of the strait.
- BIMCO’s chief safety officer Jakob Larsen warned that “the threat of mines … remains a concern” and that transits are still “very risky.”
- The International Chamber of Shipping’s Thomas Kazakos emphasized the need to prioritize the safe evacuation of roughly 20,000 seafarers still stranded.
Criticism & Opposition
Israel’s National Security Minister Itamar Ben Gvir declared the deal “does not bind us,” while Defence Minister Israel Katz said Israeli troops will remain in southern Lebanon. U.S. Senator Lindsey Graham warned that any final nuclear accord must survive congressional scrutiny. Iranian officials, including Foreign Minister Abbas Araghchi, cautioned that Tehran’s history of broken commitments could affect implementation, and Iran’s state media later suggested fees may be imposed after the 60-day toll-free window.
Conflicting Reports & Gaps
- Toll-free status: U.S. officials expect a permanent toll-free regime; Iranian statements indicate a 60-day toll-free period followed by service fees.
- Mine clearance timeline: Sources cite 40-50 days for initial clearance, while Kpler analysts estimate up to six months for full de-mining.
- Text of the MoU: The agreement’s full provisions have not been released, leaving uncertainty over sanctions relief, asset unfreeze amounts, and nuclear-program negotiations.

What’s Next
The MoU’s signing on Friday will trigger a 60-day cease-fire and initiate mine-clearance operations, likely led by the UK and France. Subsequent technical talks will address Iran’s nuclear program, sanctions relief, and the potential transition from toll-free to fee-based transit. Shipping firms are awaiting clearer guidance on safe corridors before resuming regular traffic, while oil producers in Saudi Arabia, the UAE and Iraq assess timelines for restarting shut-in output. Market observers will monitor insurance rates, mine-clearance progress, and any renewed hostilities that could alter the fragile de-escalation trajectory.
