Corporate treasurers ensure a business has enough cash, financing flexibility, and protection against shocks that could damage results or constrain investment. However, they often face large, low-probability losses from natural catastrophes, cyber incidents, and FX volatility, which affect earnings and capital needs. 

While conventional property insurance covers most of the exposure, payouts after a major loss can take months to sort. Alphabet (NASDAQ:GOOGL) and New York’s Metropolitan Transportation Authority (MTA) have adopted insurance-linked securities (ILS) to reduce earnings volatility, protect balance-sheet capital, and provide tailored risk transfer outside regular channels. 

This article explains how treasurers use ILS, the practical steps to implement it, the market perspective, and potential risks.

Key Takeaways

  • ILS allow corporate treasurers to transfer catastrophe and other low-frequency risks to capital market investors, helping stabilize earnings and preserve balance-sheet capital.
  • Catastrophe bonds, parametric structures, and collateralized reinsurance can provide tailored protection.
  • With strong investor demand and expanding market capacity, ILS is becoming an increasingly practical risk management tool for companies seeking additional sources of protection beyond conventional insurance.

What ILS Do, and Why Treasurers Use Them?

ILS convert exposures into capital-market instruments (including catastrophe bonds, collateralized reinsurance, parametric swaps, and sidecars) so investors absorb insured losses in exchange for a return.

For treasurers, ILS offers: 

  1. Non-correlated capital: ILS returns are largely unlinked to equity and credit markets. 
  2. Custom-made structure: Contracts can be calibrated to specific perils, jurisdictions, or balance-sheet thresholds. 
  3. Cost-efficiency: In some market cycles, ILS pricing competes with or undercuts traditional reinsurance.

How Treasurers Apply ILS

Earnings volatility hedges: Companies with exposure to natural-catastrophe losses can sponsor a cat bond or parametric ILS that pays when measured event metrics exceed thresholds, offsetting loss-related expenses in the income statement. This gives predictable protection for discrete events and reduces the chance of swing quarters.

Capital relief and balance sheet protection: When corporate losses could erode equity or trigger covenant breaches, ILS structures that transfer loss risk off the balance sheet preserve regulatory and lender capital cushions. Collateralized structures hold funds in trust, so payout capacity is transparent to stakeholders.

Diversification of risk transfer: By accessing alternative investors (hedge funds, pension pools, or private credit), treasurers diversify their counterparty mix and may obtain broader coverage than that of traditional markets.

Practical Steps for a Treasury-led ILS Program

  1. Identify and quantify the risk: Map exposures and tail losses by peril, geography, and legal entity. Use internal loss history and catastrophe models to generate scenario losses and confidence intervals. 
  2. Choose a trigger: This can be indemnity (actual loss), parametric (measured index), or hybrid. Weigh the speed of a parametric structure against the basis risk of a payout that doesn’t perfectly match actual losses. 
  3. Create a structure: Determine counterparty form, collateral rules, maturity, and investor payout waterfall. Collateralized vehicles increase the certainty of payment but tie up funds.
  4. Review: Confirm how the structure affects financial statements, reserves, and tax treatment. Consult auditors early to avoid unexpected consolidation or recognition outcomes.
  5. Place the deal and negotiate terms: Engage brokers and placement agents, run investor roadshows if issuing a bond, and weigh spread against expected loss.
  6. Monitor operations: Set trigger-testing procedures, predefined communications for event responses, and controls around collateral and investor notices.

Use Cases of ILS

Following the damage caused by Superstorm Sandy in 2013, the MTA issued an initial $200 million catastrophe bond called MetroCat Re. It was the first catastrophe bond designed to cover storm-surge risk and marked the MTA’s first use of capital markets for disaster insurance. The bond paid out based on measured water levels at selected tidal gauges, and the program was expanded in 2017 and 2020 to include earthquake coverage.

Google and its parent company, Alphabet, have issued three catastrophe bonds since 2020 to protect corporate operations in California against a major earthquake, even though neither company is an insurer.

Market Perspective

The ILS market has recorded capital inflows and issuance growth in recent years, expanding capacity and broadening the investor base into non-traditional perils such as wildfire, cyber, and casualty sidecars.

For example, Aon’s aggregate reinsurance capital increased to $760 billion from $715 billion year-on-year as of September 30, 2025. Meanwhile, Guy Carpenter observed a decline in its US Property Catastrophe Rate on Line Index by about 12% before January 2026 renewals, indicating that insurers were paying lower rates for the same coverage

Furthermore, Cat bond returns, measured by the Swiss Re Cat Bond Total Return Index, came in at 11.4% for 2025, a figure that beat broader fixed income and kept fresh capital flowing into the space. 

What This Means to Investors

King Ridge Capital, in partnership with HANetf, has made the Brookmont Catastrophic Bond ETF (NYSE:ILS) and KRC Cat Bond UCITS ETF (LSE: ILS) available to investors in both the U.S. and European markets, respectively. Investors who understand the risks may consider adding the asset class to a portfolio because ILS returns are driven more by catastrophe risk than by interest rates or corporate profitability.

For equity holders, a company that pre-funds catastrophe exposure is less exposed to a disaster-driven earnings shock. For bondholders, the same protection can support the credit profile by preventing a sudden cash drain from the balance sheet. 

FINRA notes that cat bonds may pay higher interest than similarly rated corporate bonds, yet investors can lose most or all of the principal if a trigger event occurs.

Possible Risks

Despite the ILS covering, corporate treasuries may be exposed to;

  • Basis risk: Payouts may not perfectly match a firm’s actual losses, leaving residual exposure. Quantify basis risk before committing.
  • Liquidity and secondary market: Several ILS are illiquid, which makes it difficult for investors to exit. Issuers should expect limited transparency of secondary pricing.
  • Event-loss and total-loss scenarios: Unlike bank debt, investor can lose their capital when triggers occur. Stakeholders should be stress-tested against covenant and rating impacts.
  • Accounting and consolidation: Certain structures can require consolidation of the SPV or affect earnings recognition. Engage an auditor in such cases.

Bottom Line

ILS have become a crucial part of the corporate treasury toolkit. It helps companies reduce earnings volatility, protect balance-sheet capital, and access alternative sources of risk transfer. 

While ILS structures require careful planning around trigger design, accounting treatment, and basis risk, they can provide tailored protection that traditional insurance may not always offer.

For companies with significant exposure to catastrophe and other low-frequency risks, a well-structured ILS program can strengthen financial resilience while broadening access to capital.

For a treasurer weighing options, the combination of soft pricing and deep investor demand makes now a reasonable time to explore a deal rather than wait.
