The Interaction Between FX and Credit Risk as an Example of Intersection of Monetary and Financial Stability Policy Goals - The Case of Serbia

The financial system of Serbia is highly bank-centric and euroised, which is a common specific feature of financial systems in developing countries. High level of euroisation represents an adequate environment for the development of emphasized interaction of foreign exchange and credit risks; therefore, creation of the spillover mechanism of foreign exchange risk to credit risk is immanent for euroised systems. Although maintaining the stability of the dinar exchange rate is a secondary goal of the National Bank of Serbia in relation to price and financial stability as the primary goals, in terms of existence of the aforesaid spillover mechanism, maintaining stability of the dinar exchange rate represents the area where there is an interaction between the goals of monetary policy (price stability) and those of financial stability policy (maintaining and strengthening the financial system's stability). In order to explore whether the spillover mechanism of foreign exchange risk to credit risk exists in Serbia's financial system, the vector autoregressive (VAR) model is applied on data from the Serbian banking sector to quantify the impact of changes in the dinar exchange rates on the rate of nonperforming loans (NPLs); the sample was formed in the period of increased instability of the dinar exchange rate, from 31 January 2008 to 31 December 2010. As we have quantitatively confirmed the impact of increase in the dinar exchange rate on the increase of 90-120 days past due NPLs, we can conclude that the existence of expressed interaction between foreign exchange risk and credit risk in the Serbian financial system represents a paradigm of the regulator's need to achieve contemporary goals of monetary and financial stability policy by maintaining relative stability of the dinar exchange rates. Depreciation of the local currency has inflationary pressure on price stability and simultaneously influences the achievement of financial stability goals through the spillover mechanism of foreign exchange risk to credit risk. In addition to taking systematic measures to reduce the level of euroisation and introduce the specific regulatory requirements, in order to protect banks and clients from the dinar exchange rate volatility, the regulator faces extremely important task of maintaining relative stability of the dinar exchange rate as the instrument to simultaneous achievement of goals of monetary and financial stability policies.
