London is the global capital of insurance. With attacks on ships travelling through the Strait of Hormuz, what is the insurance story behind the human tragedy?

Iran’s new supreme leader Mojtaba Khamenei has vowed to continue blocking the Strait of Hormuz, according to a statement read out on Iranian state television.

This follows a series of strikes on ships travelling through the gulf. As of Thursday 12th March, the U.K. Maritime Trade Operations Centre has reported 16 incidents of attacks in the Strait of Hormuz.

The Strait of Hormuz is particularly important as it is a key route for ship transportation through the Gulf. It produces around “20% of global energy raw material” according to Dr Yannis Koliousis, an expert in supply chain management. This includes oil and LNG (liquified natural gas).

“Most of the ship owners have delayed reaching or leaving the area as they are afraid of something happening”.

Simultaneously insurance costs have “increased considerably”.

This impacts costs as supply chains break down, meaning energy prices increase.

Oil prices have been volatile since the war began on the 28th of February. Costs hit almost $100 per barrel earlier today.

As dangers continue for ships traversing the waters, what is the insurance-related impact?

London finds itself at the global centre for shipping insurance. A recent report said that it is responsible for 45% of the global insurance premium for the shipping and aviation industries.

Patrick Davidson from Lloyd’s of London, the insurance marketplace, has hit back at accusations they’re refusing to cover the risk at all and said they would “still provide cover to basically anyone who asks” and that it was “not an insurance issue — it’s a question of vessel and crew safety”.

Still, that has not stopped President Trump’s government offering its own $20 billion dollar plan for reinsurance of ships in the gulf.

It is not clear yet if these moves will mean more ships will feel able to pass the Strait or not.

If the conflict does not stop then the effect could be harsher than the impact of the Russian-Ukraine war in 2022, Dr Koliousis said.

The supply chain of fertilisers, plastic and raw material are also set to be potentially affected, although the impact will be delayed.
