US naval blockade deepening insurance crisis  April 13th 2026

Trump announces US naval blockade deepening insurance crisis

When US and Israeli forces launched airstrikes against Iranian targets on 28 February 2026, the Strait of Hormuz - through which approximately 20 million barrels of oil flow each day, representing roughly 20 per cent of global petroleum liquids consumption - did not close because of mines or missiles alone. It closed, in large part, because of insurance.

Within 48 hours of those initial strikes, war risk premiums surged fivefold, major marine insurers cancelled existing coverage, and the Lloyd's Market Association's Joint War Committee (JWC) redesignated the entire Arabian Gulf as a conflict zone. Tanker traffic collapsed by more than 80 per cent before Iran's physical blockade was even formally declared. The strait was commercially unnavigable before it was militarily dangerous. That dynamic - in which insurance architecture rather than kinetic threat became the proximate cause of a global energy disruption - sets the stage for understanding why Sunday's announcement of a US naval blockade represents a further, and unusually complex, escalation for the global insurance industry.

What the Strait of Hormuz Blockade Means for Collision Repair - PartsTrader

What Will the Iran War and the Blockade of the Strait of Hormuz Mean for the Collision Repair Business?

Many observers looking at the current situation in the Middle East would likely point first to the potential impact on the collision repair industry through rising fuel prices. Higher fuel costs typically mean fewer miles driven and a corresponding decline in accident frequency, along with a slight increase in transportation costs for collision parts.

But there are a few other potential impacts worth watching.

While the region is not a major producer of automotive parts, it does supply key resources such as oil, helium, and aluminum. Roughly 20% of the world’s oil passes through the Strait of Hormuz, according to the U.S. Energy Information Administration.

The U.S. imports a significant amount of automotive-grade aluminum, and about 20% of that supply comes from the Gulf region. While that is not the majority of the raw material used domestically, the shortage caused by the blockade will compound existing constraints—especially following the three recent fires at the Novelis smelting and production plant in Oswego, New York.

Additionally, the closure of the Strait of Hormuz by Iran has severely impacted the global semiconductor supply chain by restricting the export of crucial materials, notably helium, sulfur, and aluminum used in semiconductor production. As a key transport route for Middle Eastern resources, disruption in the strait affects semiconductor manufacturing worldwide.

Reinsurers better prepared for a softening market than ever before: JP Morgan

A new report from JP Morgan has suggested reinsurers are better prepared than ever for a softening market, though price declines are expected to catch up with the sector eventually, particularly as Q1 2026 is likely to deliver far lower-than-normal catastrophe losses.

JP Morgan anticipates total insured losses from natural catastrophes to be around $10 billion in Q1 2026, well below the historical normal range of $~15 billion and meaningfully lower than the $~45 billion in Q1 2025.

The largest events during Q1 2026 were reportedly Winter Storm Fern in the US in January and Storm Nils in France in February.

Commenting on Winter Storm Fern, JP Morgan said, “The storm caused damage via freezing temperatures, heavy snow and freezing rain across parts of the US.

“While a costly event in total, we assume that Winter Storm Fern is likely not a particularly large event for the reinsurance industry with our expectation that a lot of the loss burden will fall to primary insurers instead.”
