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

Platform comparison

Market context

The Strait of Hormuz, a 54-kilometre chokepoint between Iran and Oman, remains one of the world's most strategically sensitive waterways. Roughly one-third of seaborne traded oil passes through it annually. Warship transits by non-regional powers remain uncommon but not unprecedented; the United States Navy conducts "freedom of navigation" operations periodically, whilst European navies have occasionally deployed vessels through the strait as part of broader Middle Eastern operations. The current 4% implied probability reflects the baseline rarity of such transits combined with the geopolitical friction that would typically precede or accompany them.

Historical precedent suggests transits spike during periods of heightened Iran tensions or when Western powers seek to demonstrate resolve. The 2019–2020 period saw multiple US and allied naval movements following the Soleimani assassination and subsequent tensions. By contrast, extended periods of diplomatic engagement or de-escalation correlate with reduced transit activity by non-regional militaries. The probability assessment appears calibrated to assume continued baseline stability rather than a major crisis scenario.

Traders should monitor Iranian nuclear negotiations, US policy announcements regarding the Persian Gulf, and scheduled military exercises by regional or Western powers. Recent reporting from Reuters and regional defence ministries regarding naval deployments will signal shifting risk. Any escalation in US–Iran rhetoric, Israeli–Iranian confrontation, or Houthi activity in the Red Sea could alter calculus rapidly. Conversely, successful diplomatic talks or explicit de-escalation statements would likely keep transits minimal through the settlement window.
