Insurance, War, and the Strait of Hormuz: Why Global Trade Suddenly Depends on a “Piece of Paper”
The Strait of Hormuz has always been one of the most strategically important waterways in the world. But in recent days, something unusual happened: global shipping did not stop because the waterway was physically closed — it stopped because the insurance disappeared.
This rare moment highlights a powerful but often invisible reality of the modern global economy: insurance is one of the critical systems that makes global trade possible.
For readers following the recent escalation between the United States and Iran, the insurance implications have become a major part of the story.
This article explains what is happening, why insurance markets suddenly pulled back, and why the U.S. government has stepped in with a historic insurance backstop to keep global energy moving.
🌍 Why the Strait of Hormuz Matters So Much
The Strait of Hormuz is a narrow waterway between Iran and Oman connecting the Persian Gulf to the Arabian Sea. Despite its small size, it is one of the most important trade chokepoints in the world.
Roughly 20% of global oil and large volumes of liquefied natural gas (LNG) move through the strait every day.
Energy exports from major producers such as:
- Saudi Arabia
- Qatar
- United Arab Emirates
- Kuwait
- Iraq
…all depend heavily on this route.
When shipping through Hormuz is disrupted, the effects ripple through energy markets, shipping costs, and global inflation.
⚠️ What Triggered the Current Crisis
The current situation began after U.S. and Israeli military strikes on Iran, followed by Iranian retaliation in the Gulf region.
Missile attacks, drone threats, and damage to tankers dramatically increased the perceived risk to commercial shipping.
Within days:
- Multiple tankers were struck or damaged
- Shipping companies paused transits
- Maritime traffic dropped sharply
- Oil prices surged
Some analysts say traffic through the strait fell by as much as 80% once insurance cover disappeared.
But the key point is this: shipping did not halt primarily because ships could not sail. It halted because ships could not get insured.
🚢 The Invisible Backbone of Global Shipping: Marine Insurance
Modern shipping relies on a complex web of insurance coverage.
Before a vessel can sail through high-risk waters, several parties require insurance documentation:
- Shipowners
- Cargo owners
- Banks issuing letters of credit
- Port authorities
- Crews and operators
Without insurance coverage:
- Banks may refuse financing
- Ports may deny entry
- Ship crews may refuse to sail
- Cargo owners will not load goods
Industry experts often call marine insurance the “permission slip” of global trade.
If the insurance disappears, the trade stops.
📉 Why Insurers Suddenly Dropped War-Risk Coverage
As the conflict escalated, many marine insurers and protection-and-indemnity (P&I) clubs withdrew war risk insurance coverage for vessels entering the Persian Gulf.
War risk coverage protects against losses caused by:
- Military attacks
- Missiles or drones
- Terrorism
- Piracy
- Confiscation or seizure
Several major insurers, including leading maritime mutual insurers and P&I clubs, pulled coverage for ships operating in the region.
Premiums also spiked dramatically, in some cases rising multiple times over within days.
From the insurer’s perspective, the situation looked like this:
- Missiles targeting tankers
- Active military conflict in shipping lanes
- Potential closure of a strategic chokepoint
In that environment, risk becomes extremely difficult to price. The result was an insurance vacuum.
🏛️ The U.S. Government Steps In With a $20 Billion Insurance Backstop
To stabilize shipping and global energy markets, the United States government took an unusual step.
President Donald Trump directed the U.S. International Development Finance Corporation (DFC) to provide political risk insurance and financial guarantees for maritime trade moving through the Gulf.
The program includes:
- Up to $20 billion in reinsurance capacity
- Coverage for hull, machinery, and cargo losses
- Partnerships with U.S. private insurers
- Coordination with the U.S. Treasury and military command
The goal is straightforward: restore confidence so ships will sail again.
In addition to the insurance guarantees, the U.S. government has also indicated that naval escorts could accompany tankers if necessary to secure the waterway.
This combination of military security and government-backed insurance is designed to stabilize one of the most critical arteries of the global economy.
📊 Why This Move Is So Significant for the Insurance Industry
This development is unusual because governments rarely step directly into global insurance markets.
But in extreme geopolitical situations, they sometimes do.
Examples include:
- U.S. terrorism insurance after 9/11 (TRIA)
- Government-backed insurance during major wars
- Pandemic-related risk backstops
In the Hormuz case, the government is effectively acting as a reinsurer of last resort to ensure commercial insurers can participate again.
Without that backstop, shipping companies might simply refuse to transit the strait.
🌐 The Ripple Effects Across Global Insurance Markets
The Hormuz crisis highlights how geopolitical conflict affects many insurance sectors beyond marine shipping.
Some of the most exposed areas include:
Energy Infrastructure
Oil platforms, refineries, pipelines, and LNG terminals across the Middle East face increased political violence and sabotage risks.
Aviation Insurance
Airlines flying through conflict zones carry specialized aviation war risk coverage, which insurers can cancel or reprice during major conflicts.
Supply Chain Insurance
Cargo delays, rerouted shipping, and port disruptions create claims under trade disruption and logistics policies.
Cyber Warfare
Modern conflicts often include cyberattacks targeting:
- Energy Infrastructure
- Shipping Systems
- Financial Networks
These can trigger disputes over cyber war exclusions in insurance policies.
Data Centers and Digital Infrastructure
Cloud infrastructure and data centers supporting global logistics, financial markets, and energy trading systems could become strategic cyber targets, raising questions around cyber war coverage and systemic risk.
🧭 A Bigger Lesson: Insurance Is a Pillar of Global Stability
The situation in the Strait of Hormuz is a powerful reminder that insurance is not just a financial product — it is part of the infrastructure of the global economy.
When insurers withdraw coverage, it can:
- Freeze trade
- Disrupt energy markets
- Trigger price spikes
- Reshape geopolitical strategy
In this case, the insurance system effectively became the bottleneck of global oil flows.
And the response — government-backed political risk insurance — shows how central risk management is to modern geopolitics.
📝 Final Thoughts
For most people, insurance is something purchased quietly in the background — auto insurance, home insurance, health insurance.
But in moments like this, insurance becomes visible as a strategic tool that can influence global markets and even geopolitical outcomes.
The Strait of Hormuz crisis demonstrates that:
- Wars disrupt risk markets first
- Insurance determines whether commerce continues
- Governments sometimes step in when private markets cannot absorb the risk
In short:
Sometimes the most important asset in global trade is not a tanker, a pipeline, or a port. It is an insurance policy.
