Iran's partial blockade of the Strait of Hormuz since early March 2026, amid its war with the US and Israel, has restricted most commercial and military transits, with the IRGC imposing selective tolls on merchant vessels. President Trump called on allies including the UK, France, Japan, South Korea, and others to send warships for freedom of navigation patrols, but a March 19 joint statement from seven US partners expressed support without committing vessels. Only US Navy ships, led by USS Boxer on March 23, have confirmed transits; Indian Navy warships are deployed nearby for merchant escorts. Recent upticks in limited merchant traffic as of March 31 signal de-escalation potential, but no foreign warship passages. Traders eye coalition negotiations, UN diplomacy, or US airstrikes before April 30 resolution.

A "warship transit" is defined as a military vessel passing through the Strait of Hormuz. Military cargo or support vessels will be considered “warships”; however, commercial or civilian vessels will not qualify.
For the purposes of this market, only transits through the Strait of Hormuz will be considered, defined as passage through the narrowest portion of the waterway between Iran and Oman. Operations solely in the Persian Gulf, Gulf of Oman, or Arabian Sea without passage through this narrowest section will not qualify.
Official confirmation by a national government or its military that its vessels transited through the Strait of Hormuz during the specified timeframe will resolve this market immediately. An overwhelming consensus of credible reporting confirming that such a transit occurred during the specified timeframe will also suffice.
Qualifying confirmations include statements such as official announcements that a country has deployed naval vessels to transit or escort shipping through the Strait of Hormuz.
Confirmations referring only to naval presence in the broader region, including the Persian Gulf, Gulf of Oman, or Arabian Sea, without confirmed transit through the Strait itself, as well as aerial operations, cyber operations, or actions by proxies or third parties, will not alone qualify.
The primary resolution source for this market will be official information by the respective national governments or their militaries; however, an overwhelming consensus of credible reporting will also suffice.
