European reinsurers have hit a wall after several years of strong outperformance, with momentum fading as pricing softens and growth gets harder to sustain. That’s the core message from a recent report by Autonomous, which says 2026 will test both margins and strategy.
Analysts argue that reinsurers effectively stalled in 2025. Softer reinsurance pricing cycles, FX headwinds, and pressure on top-line growth all converged.
Every reinsurer in coverage underperformed the wider sector, though the spread between winners and laggards was wide enough to matter.
Among Big Four Largest Reinsurance Companies in Europe, SCOR came out on top, gaining 23% in absolute terms. Munich Re followed with a 19% rise, while Hannover Re added 11%. Swiss Re trailed the group, up just 3%. Same market, very different outcomes.
The London Market fared worse. Performance dispersion was sharper, and the segment landed at the bottom of the subsector rankings. Investors, analysts say, have grown uneasy.
Concerns around pricing in P&C reinsurance intensified through 2025 as excess capacity piled up after an unusually profitable stretch. Alternative capital kept flowing in, adding weight to the supply side.
Exposure to the most volatile classes differed sharply by firm, which helped explain the uneven share price moves.
The January 2026 renewal season is now in motion, and expectations are already set. Autonomous says the market is braced for mid-teens rate cuts in some headline lines, mostly concentrated in property catastrophe.
Looking ahead, analysts expect reinsurers to keep getting knocked around by the same forces seen in 2025. Balance sheets look stronger, yes. But earnings growth appears to have peaked.
From here, diversification and capital flexibility start to separate the field. Those factors sit behind Autonomous’s preference for Munich Re, which remains rated OP, while Swiss Re was downgraded to UP from OP.
Autonomous expects low but still positive premium growth. The tougher call is earnings. In a market that’s growing overall, reinsurers face a harder task defending margins. The narrative shifts, analysts say, away from ROE expansion toward maintenance. Or defence, depending on the book.
Pricing still carries embedded margin despite the ongoing softening. As a result, Autonomous expects returns to hold up through 2026 and 2027.
Average ROE for reinsurers is forecast at 17.8%, versus 15.1% for London Market names. The projected ROE drop by 2027 versus 2025 is modest, about 1.6 percentage points for reinsurers and 1.1 points for London stocks.
Analysts add that hopes for cycle stabilisation have already faded. Excess capital keeps building, and without a meaningful depletion event, the direction doesn’t change. The brief optimism following the California wildfires didn’t last.
Autonomous models assume normal catastrophe experience going forward. Against that backdrop, pressure on pricing feeds directly into tougher trade-offs between growth and margin protection.
Comparing against a favourable loss year like 2025 only sharpens the contrast. Net income growth, the firm says, is likely to cool into the low single digits at best. Few exceptions. No easy outs.
