Staff Reports
Two more tankers slipped through the Strait of Hormuz this week with their transponders turned off. One was carrying crude to India and the other was a naphtha or LNG cargo bound for China. The move is not a harmless act of seamanship. It is a clear sign that Iran’s shadowy sea extortion is working — and global shipping is paying the price.
What happened in the Strait of Hormuz
Ship trackers reported that the VLCC Nissos Keros and the tanker Hua Lin Wan crossed the Strait of Hormuz with their Automatic Identification System (AIS) transponders switched off — a tactic called “running dark.” One ship is headed to India’s Visakhapatnam, the other to China’s Huizhou. Several other tankers reportedly went dark earlier, and a handful of vessels tried to sail openly but turned back. That pattern looks less like coincidence and more like a clever way to avoid paying Iran’s new tolls.
Who is behind the pressure on shipping?
Iran’s Islamic Revolutionary Guard Corps (IRGC) created the Persian Gulf Strait Authority (PGSA) to collect what amounts to a maritime toll. The U.S. government long ago labeled the IRGC a terrorist organization. Now the Treasury Department has slapped sanctions on PGSA, warning that money paid to it flows to the IRGC. If shipping companies are turning off transponders to dodge harassment or to secure “safe passage,” they are playing into Tehran’s hands — and possibly into legal trouble under U.S. sanctions.
U.S. response: sanctions and bluster
Treasury Secretary Scott Bessent announced sanctions against the PGSA and called Iran’s scheme “extortion.” He framed the move as part of a broader pressure campaign called Economic Fury. Fine — sanctions are the right tool where force is neither desirable nor available. Still, talk of a “financial stranglehold” rings hollow if tankers keep slipping through while running dark. Sanctions hurt, but they must be paired with real deterrence at sea and stronger protection for commercial shipping.
Why every American should care
The Strait of Hormuz is a global artery for oil and gas. When ships fear stopping to identify themselves, prices spike and supply chains wobble. American consumers and allied economies pay the bill. Beyond money, there’s a strategic cost: letting Iran treat international shipping like a toll road rewards bad behavior. The U.S. must not let Tehran monetize its aggression or turn merchant mariners into collateral.
This week’s run-dark incidents are a red flag. Sanctions are an important piece of the response, but they are not everything. Washington should keep tightening financial screws while working with allies to protect shipping lanes and hold Tehran accountable. Otherwise, expect more tankers to vanish off the radar — and more excuses about how “commercial realities” forced companies to pay up. That’s not reality. It’s surrender dressed as business pragmatism, and America shouldn’t applaud it.
