Strait of Hormuz Crisis: Impact on Global Oil and Shipping

Escalating tensions in the Middle East, following U.S. And Israeli strikes on Iran, have led to significant disruptions in shipping through the Strait of Hormuz, a critical waterway for global oil and trade. Several major shipping companies have suspended operations, raising concerns about potential supply chain bottlenecks and rising energy costs.

What is the Strait of Hormuz?

The Strait of Hormuz is a narrow, strategically vital sea passage connecting the Persian Gulf to the Gulf of Oman and the Arabian Sea. Approximately 100 miles long and just 24 miles wide at its narrowest point , it is bordered by Iran to the north and the United Arab Emirates and Oman to the south. It is a crucial choke point for crude oil, enabling the transport of oil and gas from the Middle East to destinations worldwide.

Why is it Important?

The Strait of Hormuz is one of the world’s most important oil choke points. In 2023, it facilitated the flow of approximately 20.9 million barrels of oil per day , representing about 20% of global petroleum liquids consumption. Roughly 20% of the world’s oil supply passes through this critical strait . The countries that rely on the Strait to export oil include Saudi Arabia, the United Arab Emirates, Iraq, Kuwait, Qatar, and Iran.

Current Disruptions

As of March 2, 2026, marine traffic through the Strait of Hormuz has slowed considerably . Major shipping companies, including Maersk, MSC, Hapag-Lloyd, and CMA CGM, have suspended operations and rerouted vessels around the southern tip of Africa . The U.K. Maritime Trade Operations Center has reported attacks on several vessels in the area and warned of elevated electronic interference to ship navigation systems . Approximately 150 tankers are currently anchored in Gulf waters on either side of the strait .

Potential Economic Impacts

A prolonged closure of the Strait of Hormuz could have severe consequences for the global economy. Experts warn that it could sharply drive up oil prices . Blockades could potentially push oil prices above $100 per barrel , potentially increasing inflation in advanced economies by 0.4 percentage points for every 10% increase in oil prices . Beyond oil, disruptions to shipping could impact the flow of other goods, further straining global supply chains.

Risks to Infrastructure

The conflict likewise poses a risk to energy infrastructure in the region. Kevin Book, managing director at Clearview Energy Partners, notes that infrastructure is at risk not only from deliberate attacks but also from inadvertent damage caused by missile interceptions . Shrapnel and debris could disable facilities, exacerbating supply constraints.
