Vessel crossings through the Strait of Hormuz declined further in June 2026, reflecting persistent security concerns in the region, according to data from Vortexa and analysis by Reuters. The strait, a critical chokepoint for global oil shipments, saw a 12% drop in tanker traffic compared to the same period last year.
The decline is attributed to heightened tensions between Iran and Western nations, including recent seizures of commercial vessels by Iranian authorities. In April 2026, Iran detained a Marshall Islands-flagged tanker, citing alleged violations, which has deterred shipping companies from transiting the waterway.
Alternative routes, such as the Bab el-Mandeb strait, have also seen increased traffic, but these add significant costs and transit times. The International Energy Agency (IEA) warned that reduced Hormuz traffic could tighten global oil supplies, though current inventories remain adequate.
Industry experts note that insurance premiums for vessels passing through the strait have risen by 30% since early 2026, further discouraging crossings. The situation remains fluid, with diplomatic efforts ongoing to de-escalate tensions.
