The study examined the impact of credit risk management on deposit money banks stability and the moderating role of corporate governance. The study period spanned 11 years (2009-2019) and twelve (12) deposit money banks were taken as sample for the study. Annual data from sampled banks were subjected to various statistical and empirical tests. The pooled model, random effect (REM) and fixed effect model (FEM) techniques of the panel least square was adopted for empirical testing while statistical testing was done using the descriptive statistics, unit root tests and co-integration tests. Credit risk management was measured using data on non-performing loans (NPL), liquid ratio (LQR), capital adequacy ratio (CAR) and loan loss provisioning (LLP) while bank size (BS) was introduced as a control variable. Corporate governance was measured using data on audit committee independence (ACI). Banks stability was measured using the Z-score of sampled banks. Empirical result indicated that NPL had a negative insignificant relationship with bank stability and a positive insignificant relationship with bank stability when corporate governance was introduced. Other credit risk management variables (LQR, CAR, LLPR) were found to strengthen banks stability although their significance were mixed. Bank size was found to be negatively related with banks stability. Premise on research findings, the study concluded that credit risk management is germane to the stability of deposit money banks in Nigeria during the period of study. It was also concluded that corporate governance although having a positive relationship with banks stability has no significant impact. Among other things, the study recommended that detailed policies and procedures for non-performing loans exposure, management and recovery are in place so as to reduce the incidence of non-performing loans.
