Insurers Turn to Catastrophe Bonds to Expand Data Center Risk Coverage

Insurers are increasingly turning to catastrophe bonds and alternative capital structures to address growing coverage gaps tied to large-scale data center developments. The shift comes as demand for insurance tied to artificial intelligence infrastructure rises and traditional capacity struggles to keep pace.

Brokers and insurers are working with private capital firms and hedge funds to issue catastrophe bonds, also known as cat bonds, as well as special-purpose vehicles. These structures aim to provide additional capital to cover risks associated with data centers, including fire, flooding, and cyberattacks.

The scale of data center investments has reached tens of billions of dollars. As a result, available insurance coverage has not kept up with lender and developer needs. Industry participants say this imbalance is driving the search for new capital sources.

Laurent Rousseau, head of global capital solutions at reinsurance broker Guy Carpenter, noted that demand for insurance continues to increase. He said the industry will need to access new sources of capital to meet that demand.

Lenders financing data center projects are seeking protection against a range of exposures. These include physical damage from fire and flooding, loss of high-value semiconductor chips, project cancellations, construction risks, and disruptions to power and water supplies.

Joe Peiser, head of risk capital at broker Aon, said insurance-linked securities tied to data centers will play a key role in addressing the volume of demand entering the market.

Cat bonds allow insurers and other issuers to transfer risk to investors. In exchange for higher yields, investors agree to absorb losses if a specified event occurs. If a triggering disaster takes place, bondholders may lose part or all of their investment.

The broader cat bond market has attracted participation from hedge funds, private capital firms, and retail investors. Higher yields relative to corporate and government debt have contributed to increased demand, driving record issuance levels in recent months.

Insurers are now exploring cat bond structures that could provide up to $1 billion in property damage coverage for a single data center or a group of facilities. These bonds would likely focus on major natural disasters such as earthquakes and hurricanes.

In addition, insurers are developing alternative investment vehicles designed to cover other risks, including cyber incidents and business interruption.

According to Rousseau, a data center cat bond offering up to $1 billion in coverage could yield at least two percentage points above comparable government bonds. These instruments are generally suited to investors seeking higher returns and willing to accept greater risk.

Industry participants also point to additional uncertainties surrounding data center projects. These include potential fluctuations in long-term demand for computing power and storage, as well as data centers’ exposure to targeted attacks. Rousseau noted that data centers are considered strategic assets and may face heightened risk in unstable geopolitical conditions.
