Credit risk adjusted bank's liquidity as a support measure for the process of financial stability management

The article focuses on the evaluation of selected methods of quantifying liquidity risk which is affected by a broad spectrum of risk factors, including in particular the credit risk. The following forms of impact of credit risk on liquidity risk were taken into consideration: (1) problems related to the influence of the deterioration of the quality of bank's loan portfolio, resulting in an increase in liquidity gap and a need to convert liquid assets into cash or obtain additional external financing, (2) an increase in credit risk of the bank (passive credit risk) resulting in disturbances in the process of obtaining external financing and an increase of its cost, (3) an increase in credit risk of issuers of securities until now classified as a resource of liquid assets (HQLA), the consequence of which is an increased risk of disposing of them. Most of the methods of liquidity risk measurement presented in this article exclude the impact of credit risk on the stability of cash flow, which questions their accuracy and determines the need for the correction of the results with regards to the potential impact of both active and passive credit risk.
