Climate change increasing frequency/severity of catastrophe losses - wildfire, hurricane, flood exposure requires continuous model updates and potential for inadequate pricing if loss trends accelerate faster than rate increases
Alternative capital (ILS, catastrophe bonds, collateralized reinsurance) compressing traditional reinsurance margins - $100B+ alternative capital market provides capacity at lower cost of capital, pressuring ROEs in benign loss years
Regulatory capital requirements (RBC, Solvency II) increasing and potentially forcing capital raises or limiting growth - particularly in Europe where Solvency II standard formula penalizes catastrophe exposure
Intense competition from Munich Re, Swiss Re, Hannover Re with comparable scale and ratings - market share battles during soft markets compress margins below cost of capital
Bermuda reinsurers (RenaissanceRe, Arch, Axis) with lower tax rates and focused cat strategies - 0% Bermuda tax vs 21% US rate creates 15-20% ROE disadvantage on comparable underwriting results
Reserve deficiency risk on long-tail casualty lines - adverse development on 2015-2019 accident years (social inflation, litigation trends) could require $500M-$1B+ reserve strengthening
Investment portfolio duration mismatch vs liabilities - 3-4 year asset duration vs 5-7 year liability duration creates reinvestment risk if rates fall after catastrophe losses force asset sales
Catastrophe aggregation risk - single major event (magnitude 8+ California earthquake, Category 5 Florida hurricane) could generate $3-5B gross loss, $2-3B net loss after retrocession, representing 15-20% of equity
