The U.S. Navy’s blockade of Iranian ports is now in its fourth day, with about 500 vessels trapped and traffic running at 10-25% of pre-conflict levels. The April 30 market for traffic returning to normal sits at 6.5% YES, down from 12% a week ago.

U.S. forces are conducting boarding operations to enforce sanctions and restrict contraband. The April 30 market reflects deep skepticism about a quick resolution given the fragile ceasefire and heavy military presence in the strait.

The May 31 market trades at 83% YES. That 76-point spread between the two contracts means traders expect the blockade to end sometime in May, not April. Daily USDC volume on the April 30 market is $2,109, with only $621 in order book depth to move the price 5 points, so a single concentrated trade could shift the line noticeably.

The blockade is a direct military and economic escalation. Trump has expressed optimism about mediation efforts, but the April odds say traders aren’t buying it. A YES bet at 6¢ pays 16.67x if traffic normalizes, but that requires a rapid diplomatic breakthrough and a meaningful shift in U.S.-Iranian negotiations within days.

Watch for Trump’s next public statements and any movement from Pakistani mediation efforts. Either could move the April and May contracts quickly.
