A tentative but significant shift is underway in the world's most critical oil chokepoint, the Strait of Hormuz.
After two weeks of near-total disruption where ships went "dark" by turning off their AIS tracking systems to avoid being targeted, many are now switching them back on. This isn't a return to business as usual, but rather a calculated signal. It suggests shipping operators are preparing for a new phase: controlled, escorted transits under the protection of a naval coalition. The situation remains fragile, but this is the first positive sign after a period of intense market stress.
To understand why this is happening now, we need to look at the chain of events. First, the immediate catalysts in mid-March created a window of opportunity. The U.S. has been actively pushing to assemble a multinational "Hormuz Coalition" to provide naval escorts. This political signaling, combined with a U.S. bombing raid on Kharg Island targeting assets linked to shipping attacks, reduced the perceived immediate threat. Furthermore, the IEA authorized a record 400-million-barrel emergency oil release, which helped calm soaring prices and made it easier for insurers to potentially offer coverage for secured passages.
Second, these actions were a direct response to the crisis in early March. The month began with attacks on tankers, reports of Iranian mine deployments, and a near-complete halt of traffic. In response, maritime insurers canceled or dramatically repriced war-risk cover, making it financially impossible for most vessels to transit. This forced operators to either anchor their ships or take long, costly detours, causing supply chain chaos. The recent AIS activity is a move away from this defensive, evasive posture.
Finally, this entire episode is rooted in long-standing structural risks. The Strait of Hormuz is a vital artery for the global economy, with about a fifth of the world's oil passing through it. A history of vessel seizures by Iran had already primed insurers to be cautious. The recent escalation simply triggered the shutdown they were prepared for. The current shift toward escorted convoys is an attempt to create a managed-risk system to reopen this critical waterway, even if the underlying tensions persist.

- AIS (Automatic Identification System): A maritime tracking system used to identify and locate vessels. Ships turning it off are often trying to hide their position.
- IEA (International Energy Agency): An organization of energy-consuming nations that coordinates collective responses to major disruptions in oil supply, such as releasing emergency stocks.
- War-Risk Cover: A type of insurance that covers damages to a vessel and its cargo due to acts of war, terrorism, or civil unrest in high-risk areas.
