Impact of credit risk and profitability on liquidity shocks of Namibian banks: an application of the structural VAR model

Summary/Abstract: The main purpose of this paper was to investigate the relationship between banks’ credit risk and profitability on liquidity shocks in Namibia for the period 2009 to 2018 using the SVAR model. In estimating the SVAR regression model, Granger causality, impulseresponse functions and forecast error variance decomposition were employed and evaluated. The sample consisted of Namibian commercial banks. By auditing liquidity data between 2009 and 2018, empirical results showed that liquidity risk is caused by a combination of structural shocks. The granger causality, impulse-response functions and forecast error variance decomposition analysis showed that credit risk (non-performing loans) is a key factor affecting liquidity conditions in Namibia in the medium to long run. In addition, the empirical results demonstrated that quality earnings (ROA) have minimal impact on liquidity conditions in the short run. Reforming assets quality policies and earnings quality policies can be valuable policy tools to minimize liquidity shortages and avoid insolvent banks in Namibia.
