Iran enacts toll law for Strait of Hormuz, impacting shipping traffic

Iran’s new toll law for the Strait of Hormuz has driven the likelihood of 80 ships transiting the strait by April 30 down to 5% YES, a sharp fall from 51% a week ago.

Market reaction

The April 30 market has collapsed over the past week, with only 6 days until resolution. The market for Strait of Hormuz traffic returning to normal by May 15 is also falling, now at 16.5% YES, down from 20% yesterday. Combined 24-hour USDC volume in the May 15 market is $36,459.

The “80 ships by April 30” market trades just $449 daily, with order book depth of only $542 to move the price 5 points. A single large order could swing odds sharply in either direction.

Why it matters

Iran’s toll law is an attempt to exert economic leverage over international shipping through the strait. The toll applies to one of the world’s most trafficked chokepoints, and the timing, amid already tense shipping conditions, makes this a calculated move to assert control rather than symbolic posturing. For traders, a YES share at 5¢ pays $1 if 80 ships transit on any day before the deadline, a 20x return. That bet requires believing in rapid de-escalation or a diplomatic breakthrough within days.

What to watch

Any announcements from CENTCOM or changes in naval operations in the region. A shift in U.S. military posture or diplomatic overtures could move these markets quickly, especially given how thin the order books are.
