The US Navy seized an Iranian-flagged vessel near the Strait of Hormuz, freezing maritime traffic and hitting oil trade routes. The market for 80 ships transiting the Strait by April 30 sits at 30% YES, down from 51% yesterday.

Market reaction

The seizure represents an escalation from asymmetric interference to direct naval action. The Strait of Hormuz Traffic Normalization market is likely to see further declines. The April 30 contract saw its biggest move with a 10-point drop at 5:48 PM, driven by immediate pessimism about any near-term resolution.

Why it matters

With 12 days left until resolution, thin liquidity means even minor trades can cause large swings. It costs $797 to move the price five points, so a handful of large orders could shift odds dramatically. Daily trading volume is $16,360 in USDC.

What to watch

Buying YES at 30¢ offers a 4.5x return if vessel counts recover, but that would require a diplomatic breakthrough within 12 days, a risky bet given the current trajectory.

US-Iran peace talks in Pakistan start April 21. A successful negotiation or ceasefire extension could move the price, while Iranian retaliation or further US naval actions would likely push odds lower.
