Ship traffic through the critical Strait of Hormuz is showing signs of life, recently reaching its highest point since the war began.
However, this is not a return to normal. Traffic is still only about a fifth of what it used to be. The key change is a shift in strategy from a total blockade to what could be called a 'controlled, selective passage.' Reports indicate that Iran's Islamic Revolutionary Guard Corps (IRGC) has established a de facto 'toll booth' system. Ships are being guided through a narrow northern channel near Iran's Larak and Qeshm islands, seemingly after negotiations and payments. This new system is the foundation for the trickle of ships now getting through.
So, what led to this change? There are a few key factors. First, intense diplomatic pressure played a major role. A recent warning from the U.S. President to 'obliterate' Iran's infrastructure, followed by a 48-hour ultimatum, significantly raised the stakes and pushed parties toward negotiation. Second, market forces created strong incentives. With the blockade sending Asian LNG prices (measured by the JKM benchmark) to near one-year highs, major energy importers had a powerful reason to find a way to get their gas carriers through the strait.
This recent thaw follows a period of extreme tension. The trigger was the U.S.-Israeli airstrike on February 28, which led Iran to declare the strait impassable. This move stranded nearly 200 international tankers, sent insurance costs soaring, and brought regular shipping to a halt. In response, the International Energy Agency (IEA) announced its largest-ever release of strategic oil reserves—400 million barrels—to calm markets and create breathing room for a diplomatic solution.
The significance of this recent increase in traffic is that it reshapes the risk to the global economy. The narrative is shifting from the threat of a sudden, catastrophic oil price shock to a more manageable, albeit persistent, risk premium. The successful passage of French and Japanese vessels, along with a deal for Pakistani ships, proves that a pathway exists for negotiated transit. Still, with the risks of military escalation and AIS signal jamming still present, the road to recovery will likely be slow and bumpy, not a straight line.
- Strait of Hormuz: A narrow waterway between the Persian Gulf and the open ocean, through which about 20% of the world's total oil consumption passes.
- IRGC (Islamic Revolutionary Guard Corps): A branch of the Iranian Armed Forces founded after the Iranian Revolution. It has significant influence over Iran's security and foreign policy.
- JKM (Japan-Korea Marker): The benchmark price assessment for liquefied natural gas (LNG) delivered to Japan and South Korea, the world's largest LNG importers.
