Catastrophe Bond Market Surges to Near-Record Heights Despite Natural Disaster Impact

The catastrophe bond market has achieved remarkable growth in the first half of 2025, with issuance surpassing $17 billion across nearly 60 transactions to become the second-largest year since the market’s inception, according to Swiss Re Capital Markets.
The first six months of 2025 marked the third consecutive year of record-breaking catastrophe bond issuance, with the overall market size — new and outstanding bond issues — climbing to $55.8 billion, after surpassing the $50 billion benchmark. This represents more than 75% growth since the end of 2020, demonstrating the market’s expanding relevance in the insurance landscape, according to Swiss Re.
Major CAT bond sponsors including State Farm, Florida Citizens, Allstate, Everest Re, California Earthquake Authority, and SageSure carrier partners secured substantial placements exceeding $750 million each, the report said. The market also welcomed nine new sponsors during the period, including residual pool participants, the first Canadian entrant, and rapidly growing managing general agent-affiliated carriers.
Investor appetite in CAT bonds remained robust throughout the six-month period, Swiss Re said, with significant capital deployment causing many transactions to be priced at better terms than initial guidance terms. This created a bid-heavy secondary market environment that persisted from early in the first quarter through the second quarter, resulting in continued spread compression across the market, per the report.
Natural Disasters Test Market Resilience
The year began with significant challenges as Los Angeles area wildfires in January generated an estimated $40 billion in insured losses, setting a new record for wildfire-related claims. The CAT bond market experienced limited direct impact from these fires, according to Swiss Re, though they contributed to erosion of aggregate structures, with worldwide index aggregate transactions and selected junior layers paying out during 2025.
Severe weather patterns continued to pressure the market, with the U.S. experiencing the second-highest number of preliminary tornado reports on record at 1,298 as of June 30, the report said. Verisk’s Property Claim Services estimated $7 billion in losses from March Midwest storms alone, the report noted, while May tornadoes potentially damaged nearly 63,000 properties with reconstruction costs approaching $16 billion.
International events also contributed to market dynamics, including Windstorm Eowyn in Europe generating insured losses of 700 million euros ($820 million), and Cyclone Alfred in Australia causing estimated insured losses ranging from 1.4 billion to 2.3 billion Australian dollars ($910 million to $1.5 billion).
Market Demonstrates Stability Amid Volatility
Despite broader financial market fluctuations driven by tariffs and foreign exchange movements, the CAT bond market maintained its characteristic low correlation to macroeconomic events, Swiss Re said. Deal flow remained steady with new issuances continuing and secondary market values showing no disruption signs.
The market’s resilience was evident in its performance metrics, with the Swiss Re Global Cat Bond Index returning 2.77% in the first half while maintaining low volatility compared to corporate high-yield instruments. Buy-and-hold investors continue benefiting from multi-year transaction structures and elevated yields from deals placed in 2023 and 2024, many of which will continue paying coupons through 2026 and 2027, the report said.
Looking ahead, barring major disruptive events, continued momentum is anticipated into the fourth quarter of 2025, positioning the market for another exceptional year of issuance, according to Swiss Re.
