Strait of Hormuz Shipping Disrupted as Iran Retaliates Against US and Israel

Oil and liquefied natural gas (LNG) shipments through the Strait of Hormuz are facing significant disruptions following U.S. And Israeli strikes on Iran and subsequent retaliatory actions by Tehran. Several oil majors and top trading houses have temporarily suspended shipments, while ships are reporting a de facto closure of the vital waterway.

Key Disruptions and Reports

Ships in the region have received radio broadcasts purportedly from the Iranian navy announcing a ban on transit through the Strait of Hormuz, a critical route for global oil trade. While Iranian officials have not issued an official statement confirming the closure, shipowners are exercising extreme caution.

According to reports from the United Kingdom Maritime Trade Operations (UKMTO), significant military activity has been observed in the strait. Bloomberg and the Australian Financial Review reported that dozens of tankers have diverted from the strait, including supertankers chartered by Shell.

Despite the widespread caution, some smaller tankers and bulk carriers continued to transit the strait on Saturday, according to Bloomberg’s Javier Blas.

Impact on Oil Markets and OPEC+

The disruptions in the Strait of Hormuz are raising concerns about potential impacts on global oil prices and supply. OPEC+, the alliance of oil-producing countries, is scheduled to meet on Sunday and may consider increasing oil output. Reuters reports that output could be increased from 137,000 barrels per day to 411,000 barrels per day to mitigate potential supply disruptions.

Strategic Importance of the Strait of Hormuz

The Strait of Hormuz is one of the world’s most strategically important energy chokepoints, linking the Persian Gulf to the Gulf of Oman and the Arabian Sea. Approximately 20% of the world’s oil consumption passes through this waterway daily, according to the U.S. Energy Information Administration.

Previous Disruptions

Oil transit through the Strait of Hormuz has been disrupted in the past during periods of heightened tensions involving Iran, including tanker attacks and vessel seizures in 2019.

Insurance Premiums Rise

Insurers are sharply raising premiums for ships operating near Iran in response to the increased risk, according to the Financial Times.

As of March 1, 2026, the situation remains fluid, and the full extent of the disruptions is still unfolding.
