The ILS Funds' Record-Breaking September: A Game-Changer for Investors?
The world of insurance-linked securities (ILS) has witnessed an extraordinary event, with September 2025 marking a historic month for investment returns. The ILS Advisers Fund Index, a trusted source, reveals that the ILS fund sector achieved its highest single-month return on record, and the numbers are impressive! But here's where it gets controversial...
Since February, investors in the ILS market have been enjoying positive returns, with only January 2025 taking a hit due to the devastating California wildfires. However, September has truly set a new benchmark, with ILS fund returns skyrocketing to unprecedented heights. The average return for September 2025 stands at an impressive 2.07%, and with 89% of ILS managers reporting their full-month returns, there's a strong possibility that this figure will rise even higher.
And this is the part most people miss: the diversity within the ILS market. While the average year-to-date return across the Index is already at a healthy 7.71%, it's the private ILS funds that invest directly in reinsurance and retrocession opportunities that are stealing the show. These funds often report their performance later, and their inclusion could elevate 2025 to one of the top performing years ever.
ILS Advisers commented on this remarkable performance, stating that "September's results surpassed all expectations, with no major insured events impacting the market." The catastrophe bond market also delivered exceptional returns, averaging 1.84% for the month. But the real stars were the ILS funds investing in private insurance-linked securities and reinsurance, which averaged an impressive 2.36% as a group.
With all 32 ILS funds reporting positive returns for September 2025, it's clear that the ILS asset class offers not only high return potential but also a wide range of strategies and risk-return profiles. For the first nine months of 2025, this year is already tracking as the third-highest return year in the Index's history, following closely behind 2024 and 2023.
The competition between pure cat bond funds and ILS funds investing in private reinsurance opportunities is heating up. While cat bond funds are slightly ahead year-to-date, the private ILS strategies are expected to overtake them before the year ends. This shift highlights the dynamic nature of the ILS market and the potential for investors to access diverse opportunities.
So, what does this mean for the future of ILS investments? Will the private ILS funds continue to dominate, or will the cat bond funds make a comeback? The ILS Advisers Fund Index, available on Artemis, provides a comprehensive view of this evolving market. It's an exciting time for investors, and the future looks bright for those willing to explore the diverse world of insurance-linked securities.
