Which countries will send warships through the Strait of Hormuz by July 31?

Platform comparison

Market context

The Strait of Hormuz, a 54-nautical-mile waterway between Iran and Oman, remains one of the world's most strategically sensitive chokepoints, with roughly one-third of global seaborne oil trade passing through annually. The question of whether additional nations will deploy warships through this passage by mid-2026 hinges on regional escalation dynamics, particularly around Iran's nuclear programme and ongoing tensions with Western powers and regional rivals.

Historical precedent suggests warship transits through the strait occur regularly but unevenly. The United States Navy has conducted freedom-of-navigation operations there for decades, whilst allied navies including British, French, and Australian vessels have periodically transited to assert passage rights and counter Iranian assertions of control. During periods of heightened tension—notably following the 2019 tanker attacks and the 2020 killing of Iranian general Qasem Soleimani—transit frequency increased markedly. However, sustained periods without major incidents have seen reduced operational activity from non-regional powers, reflecting the diplomatic costs of visible military presence in Iranian waters.

The 18-month window to July 2026 will likely turn on whether negotiations over Iran's nuclear programme stall or collapse, and whether regional proxy conflicts intensify. Recent reporting from Reuters and regional analysts indicates the incoming US administration's approach to Iran policy remains unsettled, creating uncertainty around enforcement of sanctions or freedom-of-navigation assertions. Any significant escalation in the Red Sea or Persian Gulf, or breakdown in diplomatic channels, would substantially increase the probability of additional warship deployments through the strait. Conversely, a stabilisation of nuclear talks would likely suppress such activity.
