Expansion of catastrophe bonds and ILS credit positive for re/insurers: KBRA

For insurance and reinsurance companies, the expansion of insurance-linked securities and the catastrophe bond market are viewed as credit positive by KBRA, with the rating agency explaining that the additional capacity the ILS market offers is increasingly important, supporting capital flexibility and protecting sector balance-sheets.

Increasing volumes of catastrophe bond issuance are creating greater risk transfer optionality for the traditional insurance and reinsurance market, KBRA says, highlighting the “additional avenues to access capacity, diversify counterparties, and reduce dependence on traditional reinsurance cycles.”

KBRA views cat bonds as a complementary risk transfer tool, but also one that is becoming increasingly important to re/insurers capital management strategies.

One of the key takeaways from KBRA’s latest report on cat bonds and the insurance-linked securities (ILS) market is that the structures are useful for generating greater resilience to the reinsurance market cycle and periods of market dislocation.

By locking in long-term protection backed by ILS investors, re/insurers can enhance their capital flexibility, reduce peak zone exposure and support their ratings stability through any stress periods, the rating agency says.

On the investor side, the asset class has proven attractive to allocators and sustained investor demand is making cat bonds increasingly viable as protection even as pricing softened during the January 1st 2026 reinsurance renewals, KBRA explained.

KBRA does suggest over-reliance on the cat bond could open re/insurers to other risks, saying, “issuers with outsized catastrophe exposure, weaker capital buffers, or heavy reliance on higher-risk trigger structures may face greater rating sensitivity following severe events.”

But the same could be said of over-reliance on traditional reinsurance and risk transfer with shorter tenure than cat bonds can provide, given that elevates exposure to the vagaries of a cyclical market and reinsurer appetites.

While the rating agency highlights the clear benefits of multi-year structures that can be laddered over time to provide stability in catastrophe bond form.

The growth of the catastrophe bond market has underscored the growing relevance of the product to re/insurer credit profiles.

KBRA explains that, “The disciplined use of CAT bonds, when appropriately aligned with modeled exposures and capital strategy, is increasingly a hallmark of resilient insurer balance sheets.”

KBRA also notes that, outside of the more established 144A catastrophe bond structure that are more broadly syndicated and offer greater market liquidity, there are also benefits to smaller, private deals.

“CAT bonds may also be issued through private placements with a small number of investors. While private structures typically offer limited liquidity, such issuances allow for greater customization of terms, attachment points, and risk profiles,” the rating agency states.

Even with yields now having declined, KBRA sees them as still attractive to the cat bond investor base and highlights how this support reliable investor appetite and long-term market stability for sponsors.

Summing up, the rating agency said, “KBRA views diversified access to alternative capital as credit supportive, particularly for insurers with meaningful catastrophe exposure. However, reliance on alternative capital does not replace the need for strong underwriting discipline, conservative reserving, and robust capitalization. CAT bonds are most effective when integrated into a comprehensive risk management strategy rather than used as a substitute for capital strength.”
