President Donald Trump has announced a plan to resume a naval blockade of Iran and impose a 20% “transit fee” on ships passing through the Strait of Hormuz. This policy follows a series of U.S. Central Command airstrikes targeting Iranian military objectives, which the military describes as having caused “significant damage” to Iranian forces.
The 20% Transit Fee and the Cost of Hormuz Shipping
The U.S. administration is proposing a direct financial levy on maritime traffic entering the Strait of Hormuz. For a single Very Large Crude Carrier (VLCC), the cost of this transit fee could reach approximately 50億円 yen.
This move shifts the U.S. strategy to a direct “pay-to-pass” model. By leveraging the geographical bottleneck of the Strait, the U.S. aims to create a financial mechanism regarding trade with Iran.
Did you know? The Strait of Hormuz is a waterway through which oil passes.
U.S. Central Command Airstrikes and Military Escalation
The announcement of the blockade coincides with active kinetic operations. Reuters reports that U.S. Central Command (CENTCOM) has completed the latest round of attacks against Iranian military targets. These operations have occurred over three consecutive days.

According to the Yomiuri Shimbun, CENTCOM stated that these strikes were designed to inflict “significant damage” on the Iranian military. This suggests a dual-track approach: degrading Iran’s physical military capabilities via airstrikes while simultaneously using a naval blockade and transit fees.
Comparison of U.S. Pressure Tactics
| Method | Primary Target | Reported Impact/Goal |
|---|---|---|
| Airstrikes | Military Objectives | “Significant damage” (CENTCOM) |
| Naval Blockade | Maritime Trade | Restriction of movement/trade |
| Transit Fee | Shipping Companies | ~50億円 yen per VLCC (Bloomberg) |
Global Energy Market Implications
The threat of a 20% fee on shipping may affect crude oil prices. Because the cost of transporting oil would rise, these expenses may impact global prices.
Reports from Asahi Shimbun and Yahoo! News indicate that the move targets Iran. If shipping companies refuse to pay, the blockade could lead to a halt in traffic.
Pro Tip: Investors monitoring energy stocks should watch for adjustments in the Persian Gulf as the market prices in the 20% fee.
