Best’s Market Segment Report: US and Bermuda Reinsurers Maintain Strong Performance Despite Softening Market

AM Best reports U.S. and Bermuda reinsurers produced a fifth straight year of underwriting profitability, despite premium growth falling sharply. The backdrop is a softening reinsurance market, but the ongoing profitability indicates resilience in underwriting performance. Overall, the news is credit-positive for reinsurers, though top-line momentum is weakening.

Analysis

The market is likely to misread this as a broad bullish signal for insurance, when the more important takeaway is that earnings quality is being preserved despite weaker top-line momentum. That favors the best-capitalized reinsurers and diversified balance sheets, not the marginal writers that need volume growth to offset price competition. The second-order effect is that slower premium growth also slows float accumulation, so the investment-income tailwind to 2025-26 ROE is smaller than headline profitability suggests.

Over the next 1-3 months, the key catalyst is renewal pricing and whether disciplined terms can offset softness in limit deployment. If rates keep drifting lower without a meaningful cat event, combined ratios should stay acceptable but valuation upside will likely compress as the cycle looks more mature. What would falsify the thesis is any sign of adverse reserve development or a 1-2 point deterioration in underwriting margin; that would indicate the current profitability is more cyclical than structural.

Contrarian view: consensus is probably too complacent about "stable profitability" and underestimating how quickly excess capital can erode pricing power. In a soft market, the winners are usually the firms with the lowest expense base and the best share-repurchase capacity, while less efficient writers are forced to buy growth at inferior terms. This makes the setup more of a relative-value rotation than a clean sector long.

Key Decisions for Investors

• Prefer a relative long in BRK.B against a broad insurance proxy like IAK over the next 1-3 months; BRK.B has the best mix of underwriting discipline and float, while IAK is more exposed to margin pressure if pricing softens further.
• If you want direct reinsurance exposure, accumulate RNR or EG only on a pullback and only if upcoming renewal commentary confirms sub-95 combined ratios; upside is 8-12% over 6-12 months, but the trade breaks if pricing weakens faster than reserve releases can offset.
• Set a watch alert on any quarterly combined ratio above 98 or any adverse reserve development from the sector; that would be the signal to exit longs and reassess the cycle as peaking.
• Avoid chasing the group on the headline alone; if premium growth continues to decelerate, treat the move as a quality-screening event rather than a broad re-rating catalyst.
