There is considerable speculation that Iran might retaliate for the US’s strikes on its nuclear facilities by closing the world’s busiest oil shipping channel, the Strait of Hormuz.
About 20% of global oil and gas flows through this narrow shipping lane in the Gulf. Blocking it would have profound consequences for the global economy, disrupting international trade and ratcheting up oil prices.
It could also inflate the cost of goods and services worldwide, and hit some of the world’s biggest economies, including China, India and Japan, which are among the top importers of crude oil passing through the strait.
The Strait of Hormuz is one of the world’s most important shipping routes, and its most vital oil transit choke point.
Bounded to the north by Iran and to the south by Oman and the United Arab Emirates (UAE), the corridor – which is only about 50km (31 miles) wide at its entrance and exit, and about 33km wide at its narrowest point – connects the Gulf with the Arabian Sea.
