The British Maritime Operations Authority has declared a critical maritime threat level for the Gulf, Strait of Hormuz, and Arabian Sea. The market for 80+ ships transiting the Strait of Hormuz by April 30 is at 27% YES, down from 51% yesterday.

Market reaction

The ships transiting the Strait of Hormuz by April 30 market dropped sharply after Strait traffic fell from 138 daily vessels to zero. The UK warships through the Strait of Hormuz by April 30 market is at 8.5% YES, down from 12% yesterday. The Strait transit market’s largest move yesterday was a 10-point drop at 5:48 PM.

Why it matters

The April 30 deadline is 12 days away, and traders are pricing in low odds of traffic resuming before then. Daily USDC volume for the Strait transit market is $16,360, with $797 needed to move the price by 5 percentage points. The market can still be moved by single large trades at that depth. The largest price move in the last 24 hours was driven by fears of escalation, not by any concrete sign of resolution.

What to watch

The upcoming US-Iran talks in Pakistan are the most direct catalyst. Any shift in rhetoric or agreement on security protocols could move both markets. Admiral Brad Cooper’s statements on shipping safety measures are another signal worth tracking. At 8.5¢, a YES share on UK warship transit pays $1 if the UK deploys warships by April 30, a 11.8x return. That payout requires conditions to change drastically from where they stand now.
