Despite global economic headwinds and insured losses nearing $70 billion in the first half of 2025, reinsurance market dynamics remain resilient, according to Guy Carpenter, a leading global risk and reinsurance specialist under Marsh McLennan.
In fact, renewal trends that emerged at the start of the year have continued to shape the market. These include strong reinsurer balance sheets driving an appetite for growth, a surplus of property capacity moderating pricing, disciplined underwriting in casualty lines, and a renewed emphasis on holistic client relationships.
Wildfires Dominate H1 Losses But Do Not Derail Market Confidence
Insured loss activity slowed slightly in the second quarter, leveling off after a challenging Q1. Currently, 2025 loss totals are in line with the inflation-adjusted five-year average.
Notably, the Los Angeles wildfires alone accounted for $40 billion, or 59% of all insured losses during H1. However, these wildfire losses are not expected to weaken reinsurer capital or dampen their market appetite through the remainder of the year.

Strong Financial Performance and Capital Growth Continue
Reinsurers are still performing strongly despite Q1 challenges. In 2024, they delivered a 16% return on equity, and 2025 is projected to close at 15%, maintaining robust profitability. Additionally, reinsurance capital hit an all-time high of $607 billion at the end of 2024. Guy Carpenter forecasts a further 5% to 7% increase by the end of 2025.
Dean Klisura, President and CEO of Guy Carpenter, emphasized the strength of the current market:
“The current trading environment is one of the most favorable for reinsurers in many years, evidenced by the additional capital being attracted to the sector. We see this as a tremendous opportunity to re-balance the market dynamics in our clients’ favor.”
He added that increased capacity will likely continue to moderate pricing, offer clients more diversification of reinsurance partners, and improve overall protection strategies.
Capacity Surplus Moderates Property Rates
Even with a 5% to 7% rise in demand for property catastrophe limits, reinsurers easily met the challenge. In fact, capacity exceeded demand by over 20%, allowing for risk-adjusted rate decreases of 5% to 15% for programs without recent losses. In contrast, programs impacted by losses experienced rate increases of 10% to 20%.
Property contract coverage is a critical area of focus. Guy Carpenter has incorporated AI and data science into its analysis processes to deliver proprietary benchmarking and ensure more consistent terms across the industry.

Catastrophe Bond Market Plays Key Role
Another bright spot is the catastrophe bond market, which has actively addressed client needs in 2025. In the first half of the year, $17 billion in limit was placed through 56 property catastrophe bonds and one health catastrophe bond. Impressively, GC Securities led the way, placing 23 catastrophe bonds, more than any other broker to date.
Casualty Reinsurance Maintains Discipline Amid Change
The casualty reinsurance market and losses continue to hold firm. Two major trends shaped the more stable Spring 2025 renewals:
- Cross-line collaboration: Reinsurers and clients assessed trading relationships across property, casualty, and specialty, aiming for balanced support.
- Improved underwriting: Carrier actions have significantly boosted casualty economics, especially in proportional programs where risk and premiums are shared.
As a result, ceding commissions on proportional casualty placements largely remained flat or slightly down. Meanwhile, excess-of-loss placements faced ongoing rate increases of 10% to 20%, largely due to rising claims severity. Still, renewal outcomes were highly individualized, reflecting the uniqueness of each portfolio.

Conclusion: A Favorable Outlook for Reinsurance in 2025
Overall, the first half of 2025 has reaffirmed the strength and adaptability of the global reinsurance market. With solid financials, growing capital, and disciplined underwriting practices, reinsurers are well-positioned to meet the evolving needs of clients, even amid significant insured losses and ongoing economic uncertainty.
As Guy Carpenter’s insights show, the focus now is on innovation, efficiency, and strategic capital deployment. All these are crucial for helping insurers protect their earnings and manage risk effectively in a complex world
