MarioNawfal: war‑risk premiums jump 1,000%

The underlying story is real. The viral numbers are just getting flattened into the most dramatic possible version. What actually happened was this: after U.S.-Israeli strikes on Iran in early March 2026, shipping through the Strait of Hormuz seized up, insurers repriced the route almost overnight, and war-risk cover for ships in the Gulf jumped by multiples, not basis points. Reuters reported that some premiums rose by more than 1,000%, with a representative tanker quote around 3% of hull value — roughly $7.5 million on a $250 million ship, up from about $625,000 before the crisis. (money.usnews.com) ### What is the number people are arguing about? There are really two numbers. One is the percentage jump — “up 1,000%” — which means the premium became about 11 times the old level, not that insurers are charging 1,000% of the ship’s value. The other is the premium itself as a share of the vessel’s insured value. Reuters had that aroun(money.usnews.com)ankers reportedly paid as much as 10% in extreme cases. (money.usnews.com) ### So was “5% to 10% for a normal tanker” wrong? Basically, it is too broad. There is evidence that some ships paid up to 10% — but those were described as stranded or especially stressed cases, not the clean baseline for every Gulf transit. The better read is that the market blew out fast, then partially normalized, but stayed wildly (money.usnews.com)l. (spglobal.com) ### What about the container surcharges? Those are real too, but again the details matter. Hapag-Lloyd announced a war-risk surcharge on March 1 for cargo to and from the Upper Gulf and nearby routes — $1,500 per TEU for standard containers and $3,500 per container for reefers and special equipment. So the viral “about $3,000 per container” line is directionally right for some boxes, but it is not a flat market-wide number for all container cargo. (hapag-lloyd.com) ### Why did insurers move so fast? Because marine war-risk insurance is priced for event risk, not slow trends. Once ships are being damaged, threatened, or trapped in a narrow corridor, underwriters stop treating the route like a normal commercial passage and start treating it like a concentrated-loss zone. Reuters noted at least nine vessels had suffered damage early in the crisis, which is exactly the kind of cluster that forces daily repricing. (money.usnews.com) ### Is traffic really collapsing? Yes — that part looks broadly true. Reuters said on April 29 that only six ships crossed the strait in the prior 24 hours, described as a fraction of normal traffic. A separate live tracker showed six transits versus a normal average near 60 a day, or roughly 10% of normal. That tracker is not an official source, but it lines up with the Reuters picture that traffic remains at a trickle. (msn.com) ### Why does this hit beyond shipping? Because Hormuz is not just another route. It is the valve on a huge share of Gulf oil and product flows. When insurance jumps from a rounding error to millions per voyage, and when ships refuse to sail even with cover in place, the cost spills into crude pricing, refinery runs, freight markets, and eventually co(msn.com) be available, but crew safety and operational risk are keeping ships out. (money.usnews.com) ### Bottom line? The viral claim is built on a real market shock, but it overstates the “normal” premium. The clean version is simpler: Gulf war-risk insurance exploded after the March escalation, some extreme cases hit double-digit percentages, container lines layered on new surcharges, and Hormuz traffic still has not come close to normal.
