Celem artykułu jest określenie wpływu utrzymania i zmian ratingów kredytowych formułowanych przez agencję ratingową Moody’s na wysokość spreadu kredytowego na polskim rynku długu przedsiębiorstw w latach 2010–2017. Podstawowym powodem podejmowanych działań jest próba oceny, czy polski rynek długu jest efektywny w sensie informacyjnym w odniesieniu do wiadomości rynkowych, takich jak podniesienie, utrzymanie lub obniżenie ratingu. Wykorzystywana metodyka opiera się na standardowej procedurze analizy zdarzeń. Wyniki przeprowadzonych badań nie są jednoznaczne, gdyż z jednej strony wskazują na poprawną reakcję wysokości spreadu kredytowego na zmiany ocen ratingowych, z drugiej zaś otrzymane rezultaty nie znajdują potwierdzenia w testach istotności statystycznej.
