Chubb Set as Main U.S. Insurer for Persian Gulf Shipping Amid Iran War

Tensions between the United States and Iran are creating one of the world’s most dangerous shipping environments. But instead of relying solely on military presence, Washington is turning to a less obvious but powerful tool: insurance.

The U.S. government has chosen Chubb, one of the world’s largest property and casualty insurers, to lead a government-backed program providing coverage for commercial shipping traveling through the Persian Gulf. The goal? To keep critical oil shipments moving despite rising geopolitical risks and soaring insurance costs.

This move highlights an important reality: sometimes, financial instruments can be just as crucial as naval patrols or military deterrence in stabilizing global trade.

How War Has Created an Insurance Gap

Shipping companies depend on insurance to protect vessels and cargo from accidents, piracy, or conflict. But when war breaks out, insurers often pull back or hike premiums to extreme levels.

In the Persian Gulf, attacks on vessels and increasing naval tension have made shipping one of the riskiest businesses on the planet. Many insurers have withdrawn coverage entirely. Without insurance, shipowners cannot operate legally, and banks and cargo owners won’t finance voyages.

The result? Tankers and cargo ships have been avoiding the Gulf altogether, creating a serious disruption in global shipping lanes. War-risk premiums have surged multiple times above normal, leaving operators reluctant to risk ships worth hundreds of millions of dollars.

Enter the $20 Billion Maritime Insurance Plan

To tackle the crisis, the U.S. International Development Finance Corporation (DFC) has launched a massive maritime reinsurance initiative.

Under the program, up to $20 billion in coverage will support vessels navigating the Persian Gulf. Chubb will act as the lead underwriter, issuing policies and coordinating with other U.S. insurers joining the program as reinsurance partners.

The plan is designed to cover vessel damage, cargo losses, and other conflict-related risks. Government-backed reinsurance absorbs the highest risks, letting private insurers offer coverage at manageable costs. Officials hope this will restore confidence and get ships moving again.

Why the Persian Gulf Matters to Everyone

The Persian Gulf, and particularly the Strait of Hormuz, is a strategic lifeline for global oil supplies. Roughly 20% of the world’s oil passes through this narrow channel daily.

Even minor disruptions can send shockwaves through global markets, pushing up oil prices and triggering economic instability worldwide. The ongoing conflict has slowed maritime traffic, with some vessels choosing longer, more expensive routes, and others anchoring outside the Gulf, waiting for safer conditions.

By restoring insurance coverage, U.S. officials aim to keep oil flowing and prevent a deeper disruption to energy markets.

Chubb’s Role and Global Importance

Chubb’s experience in political risk and maritime insurance makes it the obvious choice to lead. The company manages policies for vessels under this program while collaborating with other insurers to expand overall capacity.

This partnership blends private-sector expertise with government financial backing—a hybrid model designed to handle extreme risks that private insurers might avoid alone.

Chubb executives emphasize that safe, insured trade through the Gulf is essential for the global economy. Beyond oil, shipping in the region carries chemicals, LNG, food, and manufactured goods—critical commodities for countries worldwide.

Insurance as a Strategic Weapon

Insurance may not seem like a “weapon,” but in today’s high-stakes geopolitical landscape, it can be just as powerful. Governments increasingly use financial tools to stabilize trade during crises.

Even if shipping lanes remain physically open, a lack of coverage can halt traffic entirely because shipowners cannot accept the risk. By filling this insurance gap, the U.S. government aims to prevent a larger economic shock that could ripple across global supply chains.

Market Reactions and Remaining Risks

The program has been met with cautious optimism. Some analysts warn that insurance alone cannot eliminate the dangers posed by missiles, drones, or naval clashes.

Shipowners still need to assess the safety of crews and vessels before passing through conflict zones. Critics also warn that government-backed insurance exposes taxpayers to potential losses if ships are damaged or destroyed.

Supporters, however, argue that the economic cost of disrupted oil markets and global trade would be far higher than any insurance payouts.

Looking Ahead

The maritime insurance initiative represents a major step toward stabilizing one of the world’s most critical trade routes. If successful, it could restore confidence among shipping companies and ensure energy supplies continue to flow despite the conflict.

In today’s interconnected world, safeguarding global commerce sometimes requires more than warships and diplomacy—it requires financial innovation. This partnership between Chubb and the U.S. government shows that, in modern geopolitics, insurance can be a powerful tool to maintain stability.
