Annual insurance stress tests (Testy warunków skrajnych)

A regulatory return listed by the Polish Financial Supervision Authority (KNF), Poland.

Annual stress tests run by every insurer and reinsurer to KNF's methodology, to assess the effect of extreme but plausible events on its solvency. The 18th edition uses data as at 31 December 2025 and covers interest rate risk, a combined market risk scenario, climate risks (hail, convective storms and reinsurance prices, mortality and morbidity), operating cost growth, the motor portfolio, a prospective cyber scenario and a multi-year cross-sector scenario.
