Why Shipping Is Riskier in the Strait of Hormuz

The Strait of Hormuz is a narrow route for much of the world’s oil and goods. Since early 2026 vessel visibility in the strait has deteriorated sharply and commercial traffic has fallen well below normal. Some ships have stopped broadcasting AIS signals or have used false destinations, while a small number continue to transit under reduced visibility. The International Maritime Organization has condemned attacks on ships and urged a framework for safe passage, and several governments have moved naval vessels to the region to protect trade.

This environment has pushed ship operators to use tactics such as switching off tracking, false flagging and ship‑to‑ship transfers, which complicate monitoring and insurance. Maritime intelligence firms have registered far fewer daily transits than the pre-crisis average, and insurer warnings have raised the cost of voyages. The UK and France have hosted a multinational meeting and the UK has pre‑positioned a warship to improve monitoring. Insurance premiums and fuel costs have risen as shipping through the strait has been disrupted. Although some escorts and new routing efforts aim to keep shipping open, uncertainty remains for crews and owners while the security situation continues to shift.
