The Iran Ceasefire Gave Tehran a Toll Booth Over Global Oil

The Toll Booth

The ceasefire terms themselves are the story. Under the deal announced late Tuesday — less than two hours before Trump's deadline for Iran to reopen the strait — passage through the Strait of Hormuz is coordinated "in coordination with Iran's armed forces." That language effectively grants Tehran dominance over the waterway that carries 20% of the world's traded oil and gas.

The Wall Street Journal estimated the toll at roughly $1 million per ship for friendly nations. The Philippines reportedly paid up to $2 million per vessel for oil passage. Pakistan received clearance for 20 ships. US-flagged vessels are banned outright. With roughly 130 ships transiting daily in peacetime, Iran has turned a chokepoint into a revenue stream.

The deal also includes a 10-point Iranian peace proposal demanding comprehensive sanctions relief, US military withdrawal from regional bases, and war reparations — terms Washington is unlikely to accept in full. Trump called it a "workable basis to negotiate," but the gap between a two-week pause and a permanent settlement is wide.

Physical Supply Hasn't Moved

The war premium dropped on the headline. The barrels didn't follow.

Daily transits through the Strait of Hormuz remain down 90-95% from pre-war levels, with roughly five vessels per day making the passage versus 130 in peacetime. Approximately 340 tankers are trapped in the Persian Gulf — 130 carrying crude or fuel oil and 210 loaded with refined products — and none of them are moving.

The brief window when Iran reopened the strait lasted hours. After Israel struck over 100 Hezbollah targets across Beirut, southern Lebanon, and the Bekaa Valley without advance warning — killing over 250 people in Lebanon's deadliest day of the conflict — Iran halted tanker traffic again. Netanyahu and Trump both called Lebanon "a separate skirmish" not covered by the ceasefire. Tehran disagrees, and threatened to withdraw entirely if Israeli strikes continue.

Marine insurance premiums remain at 3.5-10% of vessel value, up from a fraction of a percent pre-war. But cost isn't the real barrier. As one shipping executive put it: "You can be insured, but it doesn't mean you're not still massively concerned about losing your ship, losing your crew, or causing an oil spill."

Months From Normal

Even in the best-case scenario — the ceasefire holds, Iran keeps the strait open, fighting stops — physical supply restoration is a multi-month process. Iraq, Saudi Arabia, Kuwait, UAE, Qatar, and Bahrain collectively shut in 7.5 million barrels per day in March, with production cuts expected to reach 9.1 million b/d in April. Restarting those wells takes two to three months. Producers won't commit the capital unless they believe the ceasefire is permanent, not a two-week pause.

Analysts estimate oil exports could return to pre-war levels by July at the earliest, with initial flows coming as "a slow trickle" from the most risk-tolerant operators. Military escorts, which Secretary of State Rubio described as a "post-conflict necessity," are not a near-term solution.

Brent at $95 reflects this math. The ceasefire pulled crude down from $110+ because the market discounted the probability of peace. But at $25 above the pre-war $70 floor, the price is telling you the market doesn't believe the barrels are coming back soon. The next 13 days of the ceasefire window will determine whether this is a floor or a waystation — but even if the deal holds, the oil won't flow until summer.
