The disruption in the Strait of Hormuz isn't a formal closure. Instead, shippers and producers are adopting a "wait and see" approach, halting flows due to reports of damaged ships and skyrocketing insurance premiums, effectively creating a self-imposed blockade.

A little-known feature of marine insurance is that the war risk component can be canceled by insurers with just a few days' notice during a crisis. Shippers are then forced to repurchase coverage at premiums that can be 10 to 30 times higher than the original rate, drastically altering voyage economics.

Major container lines will divert entire fleets on longer, more expensive routes around continents based solely on the threat of attack, as seen with the Houthis in the Red Sea. The perception of risk, not just the occurrence of incidents, is a primary driver of costly, system-wide disruptions in logistics.

Beyond insurance and logistics, the paramount concern is human life. In the Strait of Hormuz, a vessel was immediately abandoned by its crew after being hit, without attempting to fight the fire. This highlights that crew willingness to enter a high-risk zone is the ultimate, non-negotiable variable in supply chain continuity.

The head of inventory describes the supply chain not as a support function but as the ship's lifeblood. A single loading delay creates a domino effect, forcing the captain to burn more fuel to stay on schedule, highlighting the critical, high-stakes nature of at-sea logistics where there is no room for error.

For complex legal requests that increase your business risk or costs (e.g., unlimited liability, extensive insurance requirements), treat them as an additional negotiation lever. Explain that your standard pricing is based on a reasonable, collaborative risk profile. Accepting their terms changes that profile and will require adjusting the price accordingly.

While many fear production shutdowns, a more significant and probable risk is a logistical shock from shipping disruptions. Even modest delays in tanker transit times could effectively remove millions of barrels per day from the market, causing a significant price spike without a single well being shut down.

Insurers like AIG are seeking to exclude liabilities from AI use, such as deepfake scams or chatbot errors, from standard corporate policies. This forces businesses to either purchase expensive, capped add-ons or assume a significant new category of uninsurable risk.

When a ship is already in a crisis zone and its insurance is canceled, it has no choice but to renew at exorbitant rates. This triggers an immediate, intense negotiation—a 'slugfest'—between the ship owner and the cargo owner to determine who is contractually obligated to absorb the massive, unforeseen costs.
