Shipping traffic through the Strait of Hormuz remains depressed as the U.S. opposes Iranian plans to charge transit fees.
The waterway is a critical global chokepoint, with 20% [1] of the world's oil and natural gas passing through the narrow passage between Oman and Iran. Any disruption or added cost to this route can trigger volatility in global energy markets.
Reports on current traffic levels vary. Data from the ship-tracking firm Kpler said three oil tankers left the Strait on Sunday, May 17 [3]. However, other reports indicate a more severe decline; one report said daily ship traffic dropped from an average of 138 ships to just two in a 24-hour period ending Thursday [4].
France24 said that traffic was slightly higher last week, returning to levels in line with the average recorded since the start of the Middle East conflict [2]. This contradicts reporting from NBC News, which said shipping traffic is effectively at a standstill despite an Iran ceasefire [5].
These fluctuations occur amid a diplomatic row over the management of the waterway. President Donald Trump (R-FL) said he opposed Tehran's intentions to charge fees for use of the Strait of Hormuz [6]. The U.S. administration maintains that the waterway should remain open without tolls.
Iran has indicated it will reveal a new mechanism for managing traffic in the strait [7]. The tension persists as the region attempts to stabilize post-war shipping patterns, while the U.S. continues to oppose any financial levies imposed by Tehran on international vessels.
“20% of the world's oil and natural gas passes through the Strait of Hormuz.”
The disparity in traffic reports—ranging from a 'standstill' to a slight recovery—suggests a fragile environment where shipping companies are hesitant to resume normal operations. The U.S. opposition to Iranian tolls is not merely a financial dispute but a strategic effort to ensure the 'freedom of navigation' in a region where a small percentage of global energy flow is concentrated, meaning any formal toll system could be viewed as a geopolitical lever for Tehran.
