A single missing transponder signal at the Strait of Hormuz on March 1st triggered a domino effect no one could have planned for. The Run Chen 2, a bulk carrier, vanished from tracking systems just before midnight, reemerging hours later in the Gulf of Oman. It wasn’t alone—dozens of vessels followed the same pattern, vanishing into the dark. By morning, maritime intelligence platforms confirmed what had happened: the Strait of Hormuz had effectively shut down, not by force, but by the withdrawal of war-risk insurance coverage.
This silent shutdown didn’t just disrupt traffic—it rewrote the economics of global shipping overnight. The Clarksea Index, the industry’s benchmark for commercial shipping rates, surged to an unprecedented $53,190 per day, doubling the 2025 average. But the real shock came in the extremes. Very Large Crude Carriers (VLCCs) on the Middle East-to-China route hit a staggering $770,000 per day, a figure so high that even industry veterans struggled to process it. The Kalamos, a 2010-built VLCC operated by the Greek Embiricos family, was chartered by Bharat Petroleum at that rate—a sum that exceeded the vessel’s estimated secondhand value.
The domino effect of a blocked chokepoint
The Strait of Hormuz isn’t just one of many routes; it’s the only maritime artery connecting the Persian Gulf to the open ocean. Approximately 20 million barrels of oil and a fifth of the world’s liquefied natural gas pass through this 21-mile-wide channel daily. There is no alternative. No detour. No bypass. When the Red Sea faced Houthi attacks in late 2023, shipping lines adapted by rerouting around Africa, adding 10–14 days and burning 30–40% more fuel. The cost was steep, but the cargo still moved. The Strait of Hormuz provided no such luxury.
Then came the dual crisis. While the Red Sea remained compromised, the Strait of Hormuz closed simultaneously, creating a chokepoint scenario with no historical precedent. Container-mag.com described it as a "dual chokepoint crisis without precedent in modern container shipping." Even during the 1980s Tanker War, both routes were never fully inaccessible at the same time.
The response from the world’s largest shipping companies was decisive. Maersk, Hapag-Lloyd, and CMA CGM suspended all transits through the Strait of Hormuz, citing operational necessity rather than choice. Hapag-Lloyd imposed a $1,500-per-TEU war-risk surcharge on Persian Gulf cargo, while Maersk went further with $1,800 per TEU and $3,000 for 40-foot containers. These weren’t minor adjustments; they were emergency measures to offset the sudden, extreme risks.
Stranded tankers and crashing output
The closure didn’t just delay shipments—it trapped them. Lloyd’s List reported around 200 fully compliant tankers stranded in the Gulf, unable to leave due to insurance lapses and security risks. Their owners faced daily losses of tens of thousands of dollars in operating costs, while crews remained stuck onboard. Meanwhile, Gulf oil producers confronted a different crisis: storage facilities were filling up, and Saudi Arabia began cutting production because there was nowhere to store or export the oil.
Poten & Partners warned the situation was "not sustainable," predicting that vessels would eventually seek employment elsewhere. When that happens, the inflated freight rates—driven by a temporary shortage of available tonnage—would collapse. SEB analysts cautioned that displaced tankers could flood Atlantic markets, creating an "overpopulation" that would destabilize regional shipping dynamics.
The spike in rates, as sudden as it was extreme, carries an expiration date. The question isn’t whether the crisis will end, but when—and how violently the market corrects once it does.
The rise of invisible shipping
In the world of maritime tracking, silence speaks volumes. Argus Media reported that ship traffic through the Strait of Hormuz plummeted 94% since early March. But the decline runs deeper than numbers suggest. Many of the vessels still operating in the region are doing so "dark," turning off their Automatic Identification System (AIS) transponders to avoid detection. The Run Chen 2’s brief disappearance was just the beginning—a sign of a broader shift toward stealth operations in high-risk waters.
For insurers, shipowners, and analysts, this trend complicates risk assessment. Without reliable tracking data, the true scale of the disruption remains obscured. Yet the message is clear: when insurance withdraws, ships follow, and markets break. The Strait of Hormuz isn’t just a route. It’s a pressure point—and the world’s shipping industry is feeling the squeeze.
