Iran imposes toll on vessels for priority passage through Strait of Hormuz

Iran is charging vessels a toll for priority passage through the Strait of Hormuz. The market for 80+ ships transiting by April 30 sits at 22% YES, down from 51% a day ago.

Market reaction

The April 30 market dropped 29 percentage points after the toll announcement. Higher transit costs and potential delays are suppressing expected shipping volume. The broader traffic normalization market moved lower too, with traders discounting a return to pre-conflict levels by month-end.

Why it matters

The toll is a direct assertion of Iranian control over a chokepoint that handles roughly 20% of global oil transit. With transit costs rising and geopolitical tensions already elevated, traders are pricing in sustained disruption rather than quick de-escalation.

The market for WTI Crude Oil hitting $160 in April is at 1.4% YES. The toll could push oil prices higher if shipping disruptions worsen, but 1.4% odds show traders don’t consider $160 a realistic April target.

What to watch

With only 12 days left, buying YES at 22¢ pays $1 if 80 ships transit by April 30, a 4.5x return. That bet requires rapid regulatory or military changes in a very short window.

Watch for statements from the IRGC and shipping firms like Maersk. Any announcement of eased tolls or alternative routing could shift odds. A U.S. Navy operational update or diplomatic move from the White House would also be a significant signal.
