2025 was another significant year for the catastrophe bond market as it reached new levels of growth and was heavily battle-tested. The Brookmont Catastrophic Bond ETF ($ILS), launched on April 1, 2025 with the goal of providing investors access to an asset class historically owned by larger, more sophisticated investors. This blog post is the first of hopefully many years-in-review.
When reflecting over the past year, one of the Brookmont PM team’s primary takeaways was how large the cat bond market has continued to become. By July, total cat bond issuance had already reached a new annual record of $17.8B. By year end (12/31/2025), new cat bond and insurance-linked security issuance ultimately achieved a one-year all-time high of $24.8B.
Cat bond deal sizes also increased. Midyear, when cat bond issuance hit a former one-year annual record of $17.8B (through 6/30/2025), the total issuance was achieved in 74 transactions, compared to the 95 transactions that occurred to reach the previous year’s record.
At the end of 2025, the total cat bond market was over $61.3B, and the insurance-linked securities marketplace (of which catastrophe bonds are a subset) grew significantly on a year-over-year basis and achieved a record breaking $24.8B in annual new issuance in the calendar year.
From ILS inception through the end of 2025, the ETF posted 5.88% net return(1). This performance, in our opinion, appears attractive when compared to other areas of the bond market.
Also noteworthy is the lack of impairments experienced by the holdings within ILS in 2025. White the fund did not hold any of the debt impacted by the complete $150M payout of Jamaica's World Bank-sponsored parametric cat bond following Hurricane Melissa, the cat bond market was impacted more broadly. Attentive investors generally consider that the anticipated impairment rate (also called the expected loss rate) for catastrophe bonds has historically been 2.45%. We believe that the lack of impairment of ILS holdings in 2025 is another feather in the fund’s cap for the year.
Overall, we believe 2025 demonstrated yet again the growing investor appetite for alternative assets and a trend we don’t expect will slow much, if at all, in 2026.
Looking ahead, rating agencies such as Moody’s are already expecting another strong year of cat bond issuance thanks to high risk-transfer needs from insurers and governments, and investor demand for diversification and returns.
Here are some potential themes that we believe investors should watch for in 2026:
We remain convinced that cat bonds are no longer an obscure corner of the reinsurance industry; they’re becoming a mainstream risk-diversifier. This means that for investors looking to access them, 2026 could offer continued growth, solid income, and genuine portfolio diversification.
