US Blockade Turns Back Iranian Oil Tankers Near Hormuz Strait, Shipping Traffic Remains Sparse

On April 27, 2026, the United States blocked Iranian oil tankers near the Hormuz Strait, forcing them to turn back. Shipping traffic through the strategic waterway remained sparse as tensions between the US and Iran escalated. The US also stopped an Iranian-flagged tanker under a port blockade, according to reports.

Iranian oil tankers were turned back by the US blockade near the Hormuz Strait, with reports indicating they were clustering just shy of the blockade line. The Straits Times and Reuters reported that the US had blocked several Iranian tankers, while Bloomberg noted that the tankers were gathering close to the blockade line. The US also stopped an Iranian-flagged tanker under a port blockade, as reported by the Middle East Eye. Shipping traffic through the Hormuz Strait, a critical artery for global oil exports, remained sparse due to the US blockade. Anadolu reported that the stalled US-Iran talks contributed to the low traffic levels.
