Some oil tankers are increasing their speed while passing through the Strait of Hormuz amid rising tensions between Iran and the United States, maritime data and industry sources show.
Ship-tracking information indicates that very large crude carriers (VLCCs) are moving through the narrow chokepoint at speeds of up to 17 knots — notably faster than the usual 13 knots — as concerns grow over regional security and potential disruptions. The Strait of Hormuz, a key shipping lane through which about a quarter of the world’s seaborne oil trade passes, has seen this shift as Iran announced live-firing exercises and as the U.S. bolstered its military presence in the region.
The heightened risk environment reflects broader regional strain. Recent confrontations include Iranian naval actions and increased military activity by both Tehran and Washington, contributing to an atmosphere of uncertainty for commercial vessels transiting the area.
Compounding concerns, Iran reportedly seized two foreign oil tankers in the Persian Gulf, detaining their crews on allegations of fuel smuggling — a move that further underscores the volatile maritime security climate.
Shipping sources say that some operators are choosing to speed up transit to minimise exposure in the narrow and congested waterway, even as insurance and freight markets remain sensitive to geopolitical developments.
