Serbia's foreign exchange reserve adequacy and the factors influencing their accumulation

Abstract

In this paper, the adequacy of foreign exchange reserves in Serbia and the factors that influence their accumulation is analyzed by means of an econometric model. The relevant variables, such as the gross domestic product (GDP), the real effective exchange rate (REER) and monetary aggregate M2/GDP are included in the analysis. The unit root tests applied in the research led to the conclusion that the timeseries were integrated of the order I(1). The cointegration test revealed that there was one cointegration equation. The regression model was estimated using the quarterly data for the period from 2002q1 to 2020q3. The estimated cointegration coefficients showed that the economic activity approximated in terms of the gross domestic product (GDP) had a significant influence on foreign exchange reserves accumulation, which is only followed by appreciation pressure on the dinar (approximated by the REER index) and money supply growth (estimated through the monetary aggregate M2/GDP). In addition to conventional factors, the analysis also points out specific factors and their impact on foreign exchange reserve accumulation in Serbia. The results of the research study show that foreign exchange reserves in Serbia are greater than the levels suggested by standard optimality criteria. The findings also suggest that it is necessary to take into account the dividends realized by foreign investors, as well as some segments of portfolio investment in assessing the specific indicator of the adequate level of foreign exchange reserves.
