Why catastrophe risk can be genuinely different
A catastrophe bond generally transfers specified insurance risk from an insurer, reinsurer, or other sponsor to capital-market investors. Investors receive a spread while their principal is at risk if contractually defined catastrophe conditions are met.
This creates a very different return engine from equities or ordinary corporate credit. A hurricane, earthquake, wildfire, or other covered event can impair the bond even when financial markets are calm; conversely, a recession does not automatically trigger a catastrophe loss.
Attachment, exhaustion, and expected loss
The word “cat bond” says little about risk. Two bonds exposed to the same hurricane can have radically different loss probabilities depending on the layer of insurance risk transferred.
Attachment
The point at which the investor begins to lose principal. Higher attachment generally means more sponsor losses must occur first.
Exhaustion
The point at which the investor's principal can be fully lost.
Expected loss
A modeled estimate—not a promise—of average annual principal loss under the model assumptions.
Spread
The compensation investors receive for taking catastrophe risk, before realized losses and manager costs.
Trigger structure matters
Losses may be determined by indemnity, industry loss, parametric measurements, modeled loss, or combinations of these approaches. Each creates a different balance between sponsor protection and investor basis risk.
We want the trigger to be understandable enough that an investor can explain what event causes loss, who calculates it, what data is used, and how disputes are resolved.
Collateral is a separate underwriting question
Catastrophe risk can be uncorrelated with public markets, but that benefit can be undermined if collateral itself carries financial-market or counterparty risk. We generally prefer transparent, fully collateralized structures using high-quality eligible collateral and well-understood custody arrangements.
Portfolio construction is the real investment
A single Florida hurricane bond is not a diversified catastrophe strategy. Diversification should be assessed across peril, geography, season, sponsor, attachment level, trigger type, maturity, and model family.
Model risk also creates correlation: many securities may look independent but rely on similar assumptions about storm frequency, climate, property values, vulnerability, or industry-loss estimates. We therefore favor specialist managers that clearly disclose modeled and non-modeled concentrations.
How we would approach access
For this category, EDB Capital would generally expect to evaluate specialist insurance-linked securities managers or diversified institutional structures rather than source individual catastrophe bonds through a public website. Manager selection, portfolio transparency, leverage, collateral, and loss history are central to diligence.
