US naval blockade turns back 28 ships from Iranian ports amid tensions

The U.S. naval blockade has directed 28 vessels to turn back from Iranian ports, pushing the market on Strait of Hormuz traffic normalizing by June 30 down to 25% YES.

Market reaction

Traders are betting against a quick resolution. The odds for the Strait of Hormuz traffic returning to normal by June 30 have dropped, with the 28-ship turnaround signaling that normalization is unlikely without a diplomatic breakthrough. With 71 days until resolution, the market is pricing in sustained disruptions.

Why it matters

Volume in this market is currently zero, which itself is informative. Traders may be waiting for clearer signals before placing bets, or the current odds already reflect a consensus that normalization is improbable in this timeframe. The market is thin, with no order book depth data available, so any substantial trade could swing the odds significantly.

This enforcement action signals a deepening of the conflict and makes diplomatic resolution less likely in the near term. CENTCOM’s actions, combined with the expiration of the U.S.-Iran truce, point to a prolonged standoff. At 25¢, a YES share pays $1, a 4x return if traffic normalizes by June. Taking that bet requires believing in a rapid diplomatic pivot within 71 days.

What to watch

Official statements from President Trump, moves by the IRGC, and any signs of renewed negotiations. Any of these could shift the odds if they indicate a path toward de-escalation.
