Credit risk management in the banking industry does not mean to eliminate credit risk entirely but it enables banks to bring the risk to acceptable parameters or take a balancing step between risk levels and profits so that extreme level of such risk does not hamper operational performance. The menace of poor credit risk management had continued to impede banking operations in Nigeria over the years, resulting in liquidation, merger and acquisition of players, as well as reform exigencies. The objective of this study therefore is to analyse the impact of credit risk management on growth rate of deposit money banks in Nigeria. This study adopted the expost facto research design. the study made use of secondary data sourced from the annual report of banks selected for the study covering a period of 14 years, spanning from 2005 to 2018. This study analysed the relationship among credit risk management and growth rate of fifteen (15) selected deposit money banks in Nigeria, with focus on the post-consolidation period covering 14 years spanning from 2005 to 2018. Inferential statistics was used to analyse the data. Findings revealed that when cross sectional effect is incorporated into the model, all the explanatory variables except firm's size exert negative impact on growth rate. In specific term, coefficient estimate stood at -.5497109 (p > 0.05) for non-performing loan, -.9964811 (p <0.05) for nonperforming loan to total loan ratio, -1.988666 (p> 0.05) for non-performing loan to shareholders fund ratio, -.7472075 (p <0.05) for loan loss provision and 27.86565 (p > 0.05) for firms size, while for the period specific estimation, the result stood at .0162032 (p > 0.05) for non-performing loan, -.086418 (p <0.05) for nonperforming loan to total loan ratio, .4682801 (p> 0.05) for non-performing loan to shareholders' fund ratio, -.6192235 (p <0.05) for loan loss provision and 36.34827 (p < 0.05) for firm's sizeconcluded that effective credit risk management is necessary if operational performance of deposit money banks must be sustained, because inability to manage the credit risk framework of banks will be evident in terms of rising non-performing loan; rising ratio of non-performing loan to total loan, shareholder's funds and loan loss provision which on the average will engender reduced level of performance q` of the banks. The study recommended that Deposit money banks in the country should prioritise the need to devise a well-structured credit risk management design that is based on optimal operating framework so as to maintain a desired level of organizational growth.
