Key Takeaways:
- Iran has capped Strait of Hormuz vessel traffic at 15 ships per day under the April 7 US-Iran ceasefire brokered by Pakistan.
- The IRGC-enforced limit kept Brent crude near $94.75 and WTI at $93 as of April 9, 2026, sustaining global energy market volatility.
- US VP JD Vance leads Islamabad talks expected April 10, where Iran’s asset-unfreezing and UN resolution demands will face direct pressure.
Global Oil Supply at Risk as Iran Enforces 15-Ship Daily Limit on Hormuz Passage
Russia’s state news agency TASS reported the restriction on April 9, citing an unnamed senior Iranian official. The cap represents a steep reduction from pre-conflict traffic levels, which typically ran between 100 and 150 vessels daily through the 21-mile chokepoint between Iran and Oman.
The strait carries roughly 20% of global seaborne oil, along with significant volumes of liquefied natural gas and fertilizers. Even under ceasefire conditions, actual ship movements remained minimal, with only four vessels tracked on April 8 and traffic described as nearly nonexistent through April 9.
All transits through the waterway now require prior Iranian approval and direct coordination with Iranian armed forces. Ships must follow a navigation map issued by the Islamic Revolutionary Guard Corps, routing vessels closer to the Iranian coast, a precaution attributed to mines planted in traditional shipping lanes during the conflict.
The Iranian source told TASS there would be “no return to the pre-war status quo.” Additional ceasefire conditions include unfreezing Iranian assets within two weeks, a formal end-of-war resolution through the United Nations (UN) Security Council, no increase in US troop deployments, and compliance with uranium enrichment terms. Iran has warned it will resume combat operations if those demands go unmet.
The current crisis traces to late February 2026, when the United States and Israel conducted strikes on Iran. Tehran responded by attacking merchant vessels, laying mines, and blockading the strait to ships linked to the US, Israel, and allied nations. Oil benchmarks climbed above $100 per barrel in the weeks that followed, with physical crude prices reaching near $150 in some markets.
Pakistan brokered the ceasefire, and US President Donald Trump described Iran’s 10-point proposal as a “workable basis” for continuing negotiations. Talks are scheduled in Islamabad beginning around April 10, with Vice President JD Vance leading the US delegation. The ceasefire has already faced strain from Israeli military activity in Lebanon and disagreements over Hormuz terms.
As of 11:30 a.m. Eastern time on April 9, Brent crude stood at $94.75 per barrel and West Texas Intermediate at $93. Both benchmarks had pulled back from wartime peaks above $100 but ticked higher through the session as ceasefire fragility weighed on markets. European governments pushed back against Iran’s conditions.
Italian Prime Minister Giorgia Meloni told parliament on April 9 that full reopening of the strait is a “vital interest” for Italy and the European Union, warning that any Iranian duties or restrictions would carry “unpredictable economic consequences.” UK Foreign Secretary Yvette Cooper called for the waterway to be reopened on a toll-free basis and led diplomatic outreach across dozens of countries, stressing that Iran must not be allowed to impose fees and that Lebanon must be included in the ceasefire framework.
Gulf states, including the UAE, rejected any weaponization of the strait or the imposition of tolls. France announced preparations for naval escort missions to facilitate safe passage. Trump stated publicly that the strait is “OPEN and SAFE,” though shipping companies and insurers have not yet acted on that assurance.
Reports have cited potential Iranian toll demands of up to $2 million per vessel, some even noting the acceptance of bitcoin and stablecoins. Analysts say such fees likely conflict with customary international maritime law, though enforcement mechanisms remain limited. Oman has formally rejected any revenue-sharing arrangements.
Shipowners and cargo operators remain cautious despite the ceasefire announcement. War-risk insurance premiums remain elevated, and operators are waiting for clearer signals before restoring normal routing through the strait.
The Islamabad talks will test whether the 15-vessel limit holds, expands, or collapses entirely. Iran has left little ambiguity about its position. Whether the US and its partners can negotiate a durable return to open transit remains the central question heading into the next round of talks.
