U.S.–Iran Naval Skirmishing Around Hormuz Likely to Solidify Into Sustained Limited Maritime War

Full prediction
Over the next seven days, the current U.S.–Iran missile exchange is likely to mature into a sustained pattern of limited naval conflict featuring periodic anti-ship missile launches, drone strikes, and mine warfare around the Strait of Hormuz and Gulf of Oman. U.S. and allied navies will intensify escort operations and mine-countermeasures, while Iran leans on small craft, proxies, and coastal batteries to impose a persistent threat rather than outright closure. This “low-intensity maritime war” will keep insurance costs high, reduce effective tanker throughput, and maintain elevated global oil prices, while raising the odds of an accidental mass-casualty incident or the loss of a major naval platform. Confirmation would be recurrent episodes of missile fire and mine-clearing over the week without a durable ceasefire; rapid, verifiable de-escalation through third-party mediation would undermine this forecast.
