Iran is reportedly creating a new reality in the Strait of Hormuz, demanding payments for "safe passage."
This situation isn't a simple blockade but a more complex shift toward a monetized transit system. Following recent military escalations, including attacks on merchant ships, maritime insurers canceled war-risk insurance coverage for the Gulf. This single move made it financially impossible for most ships to pass through the strait, as the risks became too high to bear without insurance.
This created a vacuum that Iran is now exploiting. The causal chain is quite clear. First, after U.S.-Israeli strikes, Iran's Islamic Revolutionary Guard Corps (IRGC) broadcast warnings for ships not to enter, creating a de facto closure. Second, as physical risks mounted, the insurance market withdrew, paralyzing conventional shipping. Third, Iran then began offering selective, bilateral approvals for passage to ships from countries like India and Turkey, establishing itself as the gatekeeper. These "approvals" have now reportedly evolved into a "pay-to-pass" system, where fees are exchanged for guaranteed safe transit through an Iranian-controlled corridor.
The implications are significant. Instead of a complete shutdown, which would trigger a massive international response, this approach rations access to the strait. It allows Iran to exert control and generate revenue while keeping global energy markets in a state of sustained tension. This maintains a structural risk premium on oil prices, keeping them elevated, and drives up freight and insurance costs for anyone who can secure passage. The International Energy Agency's emergency oil release can only act as a temporary buffer against this new, managed scarcity.
Legally, this is a murky area. The United Nations Convention on the Law of the Sea (UNCLOS) generally prohibits unilateral tolling in international straits. Iran would likely frame these payments as fees for "security services" rather than tolls, but the economic effect is the same. While evidence for selective passage is strong, direct confirmation of these payments is still emerging from trade press and industry sources, so it's best to view it as a highly plausible development rather than officially verified fact for now.

- War-risk insurance: Special insurance coverage for ships operating in high-risk areas, protecting against losses from events like war, piracy, and terrorism.
- UNCLOS (United Nations Convention on the Law of the Sea): An international treaty that defines the rights and responsibilities of nations with respect to their use of the world's oceans.
