Iran has set up a toll system for ships passing through the Strait of Hormuz, pushing odds of Strait of Hormuz traffic normalization by April 30 lower as traders price in continued restrictions.
Market reaction
The toll directly affects the April 30 market, with an expected 15% drop in YES odds. The May 31 market faces a smaller estimated 10% decrease, though the longer time horizon leaves more room for resolution. No significant volume has appeared in either market over the past 24 hours, consistent with traders staying on the sidelines.
Why it matters
The Strait of Hormuz carries around 21% of global petroleum liquids. The toll system amounts to Iran asserting control over this chokepoint without fully closing it, a moderate escalation that maintains pressure while stopping short of full confrontation. Maersk’s decision to wait for a risk assessment before resuming operations reinforces the bearish case.
For traders, a YES share in the April market may now be overpriced unless there’s a rapid de-escalation or policy shift from either Washington or Tehran.
What to watch
The key signals are announcements from the IRGC or Iran’s Foreign Ministry on the toll regime, and statements from major shipping lines (Maersk, Hapag-Lloyd) about service resumptions. Movement on either front could shift market odds quickly.
