Hormuz risk spikes insurance premiums to 10%

The Strait of Hormuz has not closed. Shipowners, insurers and banks are closing it anyway, one commercial decision at a time. Roughly 20 million barrels per day normally transit the narrow exit from the Persian Gulf (BBC Afrique). As US-Iran military escalation makes each voyage riskier, private actors are rationing access to the route, and Europe's energy costs are rising with no formal blockade to point to.

Captains wait, insurers reprice, Europe pays

Greek-managed vessels show the pattern. Some operators refused a US-coordinated passage scheme, and around nine Greek LNG carriers stayed inside the Gulf rather than risk the transit (Capital/Reuters). More than 130 tankers and gas carriers were tracked sitting west of Hormuz, waiting (OT). Merchant ships that did move switched off tracking transponders and hugged Oman's coast (Politiken). The strait is navigable. Captains judge it not worth the risk.

War-risk insurance premiums jumped to 3%–10% of hull value, up from roughly 0.25% before the crisis (The National). The Lloyd's Market Association pushed back on reports that insurers had stopped writing policies altogether: cover exists, but traffic dropped because crews and vessel operators decided the voyage was too dangerous (LMA). Container carriers issued selective booking stops and emergency surcharges for Gulf ports (Jordex). VLCC spot rates climbed 11.7% in a single week (Sahmino).

The price chain into European kitchens

Europe does not need to lose a cargo to feel the impact. Benchmark markets price the next marginal replacement, so any expected squeeze on Gulf supply pushes European costs up immediately. The TTF front-month contract, Europe's key gas benchmark set in the Netherlands, hit a one-month high as Gulf disruption tightened LNG supply expectations (BusinessAM, Investing.com). Mediterranean refined-product quotations jumped 12.82%–17.08% in a single week (FIGISC). At the pump, Dutch petrol prices rose from €2.205 to €2.297 per litre over two weeks (CBS).

Bypass capacity is thin. Pipeline and overland alternatives can reroute roughly 3.5–5.5 million barrels per day of the 20 million that normally pass through; for LNG, no comparable workaround exists (Les Clés du Moyen-Orient). Eni chief executive Claudio Descalzi called this the worst crisis since the 1980s, singling out diesel, jet fuel and LNG as the sharpest pressure points: crude oil has more rerouting options, but refined products and gas do not (Corriere della Sera). Europe entered the summer with average jet-fuel stocks covering fewer than 30 days (Corriere della Sera).

No European mandate for Hormuz

The EU does have a naval mission protecting merchant shipping: EUNAVFOR ASPIDES, which has shielded more than 670 vessels in the Red Sea (EEAS). But EU foreign policy chief Kaja Kallas said member states want ASPIDES to stay focused on the Red Sea. Extending it toward Hormuz would require new operational planning and unanimous agreement among EU governments, neither of which is under way (EEAS). France has warships positioned for Gulf contingencies, but foreign minister Jean-Noël Barrot conditioned any escort or demining role on calmer conditions and consent from coastal states, including Iran (Quai d'Orsay, BFMTV). NATO's mutual-defence clause (Article 5) applies only to attacks on member territory in Europe and North America; Iranian strikes on US facilities in Bahrain or Kuwait would not automatically trigger it (NATO Treaty).

The commercial chokepoint is already producing European costs. The evidence that will show how deep they cut sits with insurers writing war-risk clauses, banks clearing letters of credit, and traders cancelling cargoes. These are the actors who decide whether Hormuz works, and European governments have no tool to command their risk appetite.
