The determinants of excess reserves in the PNG banking system
This presentation examines why profit-maximising commercial banks in PNG demand non-remunerated excess reserves. An autoregressive distributed lag model is employed to estimate the determinants of excess reserves using time series data for the period January 2002 to December 2017. The model includes precautionary and involuntary factors that affect excess reserves in commercial banks. The findings suggest that discount rate, volatility of demand deposits and private sector deposits contribute to the accumulation of excess reserves, while foreign exchange reserves, private sector credit and treasury bill rates effectively reduce excess reserves pressure. The required reserve ratio, however, is not effective in influencing the demand for excess reserves. This empirical analysis concludes that involuntary variables are the leading determinants of excess reserves in PNG – and suggests that in order to address persistent excess reserves in the banking system, the central bank could consider potential policy interventions such as paying interest on reserves that commercial banks hold above the required limit and stimulating demand for domestic credit.
