Specialty insurance catastrophe loss impact isolates the effect of current accident-year catastrophic events on underwriting results after applicable reinsurance and reinstatement premiums.
Arch Capital's insurance segment reported 8.0% of catastrophic activity in Q2 2026, compared with 2.9% in Q2 2025.
Catastrophe impact is not the underlying loss ratio
A catastrophe-heavy quarter can raise the reported loss ratio even if pricing and ordinary claim frequency have not changed by the same amount. Investors often separate this volatility before judging recurring underwriting quality.
Read catastrophe impact with combined ratio excluding catastrophe and prior-year development. The adjusted view removes both current catastrophe noise and prior-year reserve development rather than treating either as current underlying performance.
