Iran Controls Strait of Hormuz as Shipping Lags and Oil Hits $150 per Barrel

Shipping through the Strait of Hormuz remained a fraction of normal levels this week despite a two‑week U.S.–Iran ceasefire that was supposed to reopen the world’s most important energy chokepoint aa +1. With only a handful of vessels making the passage each day, physical oil prices have surged toward record highs and governments are racing to backstop war‑risk insurance for tankers arabnews +1.

Iran and the United States agreed on 7–8 April to a Pakistan‑brokered ceasefire that included the “complete, immediate and safe opening” of Hormuz as a central condition aa. Yet ship‑tracking data showed traffic stuck at an average of about seven ships a day since the war began, compared with roughly 120–130 prewar, leaving an estimated 3,000 vessels waiting in and around the Gulf marketwatch +1. Tehran has instead offered tightly controlled, pre‑approved passages along a corridor hugging its coastline, effectively turning the narrow waterway into a tollgate controlled from Tehran marketwatch.

A Trickle of Ships Through a Chokepoint for 20% of Global Oil

Before the war, about one‑fifth of the world’s oil and liquefied natural gas exports passed through the 21‑mile‑wide strait, making it the single most critical node in global energy trade marketwatch. Since late March, Iran’s threats and attacks, combined with sky‑high war‑risk premiums, have deterred most commercial operators; at times, only four vessels a day have been visible exiting the Gulf, according to Bloomberg vessel tracking moneycontrol.

Even after the ceasefire, Iran has required captains to seek its permission and, in some cases, accept escorts before entering a narrow coastal corridor, a system that major shipowners say leaves crews exposed and schedules unworkable marketwatch +1. “There’s a very low appetite” among seafarers to transit Hormuz in these conditions, noted one industry leader, as crews weigh danger pay against the risk of missile or drone strikes bloomberg. Analysts warned that even if formal restrictions eased, it could take weeks or months to clear the backlog and return flows to anything like normal levels ua.

Oil Market Tightens as Insurance Becomes a New Weapon

The disruption has removed or throttled at least 12 million barrels per day of Middle Eastern supply — about 12% of global output — abruptly tightening the physical oil market arabnews. Refiners in Europe and Asia have bid up prompt cargoes, driving dated Brent and key North Sea grades toward $150 a barrel, well above futures prices and near or beyond 2008 records arabnews. “The market is scrambling for prompt, refinery‑usable barrels,” Morgan Stanley analysts said, underscoring that panic is concentrated in oil that can be delivered now rather than months ahead arabnews.

War‑risk insurance has become a central battlefield. Premiums for Gulf voyages have jumped as much as 1,000%, with worst‑case single‑transit cover for a supertanker estimated at up to $7 million, according to brokers and insurers nytimes. India is preparing a $1.5 billion sovereign guarantee fund and a $300 million industry pool to keep its tankers and importers insured, while Washington has doubled the size of a new reinsurance scheme to cover up to $40 billion of potential losses, drawing in giants such as Berkshire Hathaway and Travelers nytimes +1.

The Bigger Picture

With a fragile ceasefire, constrained shipping and Iran asserting de facto gatekeeper status at Hormuz, energy markets and policymakers are operating on the assumption that any “reopening” will be partial and volatile. Even if more ships trickle through in the coming days, analysts expect elevated prices, high insurance costs and rerouted trade to feed into inflation and growth pressures well beyond the Gulf. What began as a military confrontation has morphed into a protracted test of how much economic pain the world can withstand when the most important artery of global energy trade is reduced to a narrow, conditional passage.
