credit rating banku, cykl koniunkturalny, panelowe modele probitoweAbstrakt
Głównym celem artykułu jest analiza zachowania credit ratingu banku w czasie koniunktury i dekoniunktury gospodarczej, przy uwzględnieniu wskaźników finansowych. Na podstawie przeglądu literaturowego postawiono następujące hipotezy badawcze: „Podczas kryzysu w sektorze bankowym występuje silniejszy wpływ wskaźników adekwatności kapitałowej” oraz „Noty ratingowe banków podczas dekoniunktury są niższe niż w okresie prosperity”. Do badania wykorzystano dane kwartalne z lat 1998–2016 dla europejskich banków. Postawione hipotezy zostały zweryfikowane przy użyciu panelowych uporządkowanych modeli probitowych dla długoterminowych credit ratingów banków. Przeprowadzone badania dowodzą, że w momencie kryzysu rating nadawany przez Fitch i Moody bankom jest niższy niż w okresie koniunktury w sektorze bankowym. Ponadto zauważono, iż noty S&P są niewrażliwe na analizowane zmiany.
