What are the challenges of securing shipping in the Strait of Hormuz?

Dan Caine, Chairman of the Joint Chiefs of Staff of the United States, said that the Pentagon was looking into ways to safely escort vessels through the Strait of Hormuz.

Iran, located on the northern coast of the country, has effectively closed this strait. According to United Nations data, traffic through the strait is down 97% since February 28 when the U.S. and Israel war against Iran started.

The U.S. aims to calm the oil markets, as they are concerned that a prolonged war could cause a global crisis of energy.

What is at stake?

The Strait of Hormuz is a "narrow" passage of water that connects the Gulf of Oman with Iran. It's the only sea route for countries like Kuwait, Iran, Iraq and Qatar, which produce oil and gas.

On Monday, oil prices briefly rose to their highest levels since 2022. According to the United Nations, high oil prices may trigger a new cost of living crisis similar to what happened in 2022 after Russia invaded Ukraine.

A prolonged conflict may also lead to a fertilizer shortage, putting the global food supply at risk. According to Kpler, about 33% of all fertilisers in the world, including ammonia and sulphur, travel through the Strait.

A prolonged war could cause fears of an economic crisis in the world similar to the ones that followed the Middle East oil shocks in the 1970s.

What has Iran threatened?

The Iranian Revolutionary Guards warned that ships passing through the Strait would be shot at. Since the conflict began, at least 11 ships were attacked.

Most of the traffic is halted. This is partly due to caution, but also because insurance premiums have been raised by up to 300%.

What have the US and other countries promised?

On March 3, President Donald Trump announced that the U.S. will provide protection for oil tankers through the Strait of Hormuz.

He said that he also ordered the United States Development Finance Corporation (USDFC) to provide insurance and guarantee for shipping companies.

Emmanuel Macron, the French president, said that several European countries as well as India and other Asian nations were planning a mission to provide security. He said that such a mission could only be carried out once the conflict is over.

France has deployed about a dozen navy vessels, including an aircraft carrier strike group to the Red Sea, the Eastern Mediterranean and possibly the Strait of Hormuz.

A spokesperson for the British Prime Minister Keir starmer said that he had spoken to the German and Italian leaders on options of providing support?for commercial shipping within the Strait.

General Caine, speaking to reporters at the Pentagon Tuesday without giving any details, said: "We are looking at various options."

Why is it so difficult to secure the HORMUZ?

It is difficult to defend the Strait of Hormuz. According to shipping broker SSY Global, the shipping lanes are only two nautical miles wide. Ships must turn around and face Iranian islands as well as a mountainous coastline that offers cover for Iranian forces.

IS IT POSSIBLE TO PROTECT SHIPS TRAVELING THROUGH HORMUD?

Tom Sharpe (a retired Royal Navy Commander) said that although Iran's conventional naval force has been largely destroyed, the Islamic Revolutionary Guard Corps has plenty of weapons to do damage. These include fast attack craft, uncrewed surfaces vessels, speedboats mini submarines mines and even explosive-packed jet skis.

According to the Centre for Information Resilience (a non-profit group of researchers), Tehran is able to produce 10,000 drones per month.

Sharpe stated that it would be possible to air-cover three or four vessels a day in the short term using seven or eight destroyers. However, doing this for several months would require additional resources.

Adel?Bakawan is the Director of the European Institute for Middle East & North African Studies.

Kevin Rowlands is the Editor of RUSI's Journal, at the Royal United Services Institute.

He said that "the world needs oil flowing through the Gulf and so there are plans in place to put protective measures in place."

What happened in other shipping chokepoints in the region?

Yemen's Houthis - a group allied to Tehran - but with a much smaller arsenal than Iran - managed to close down the majority of traffic through the Red Sea, Bab al-Mandab Strait, and on the way to the Suez Canal, for over two years despite the protection provided by U.S.-led forces and European Union-led troops.

The majority of?shipping firms still use a much longer route via southern Africa. Danish shipping company Maersk announced that it would return to the Suez route in phases starting January.

The EU-led force that countered piracy off the coast of Somalia has had more success than Iran's Revolutionary Guards, despite being a far inferior force.

AREN'T THERE OTHER WAYS TO USE THE STRAIT?

The UAE and Saudi Arabia are looking for ways to bypass this strait. They have built more oil pipelines.

These alternatives are also not operational at the moment. An attack by Houthi militants on a Saudi east-west pipeline in 2019 proved that they were vulnerable. (Additional reporting from Renee Maltezou, Kate Holton and Charlie Devereux. Editing by Timothy Heritage.)
