The paper deals with the impact of the Euribor and risk premium on interest rates on foreign currency loans and FX-indexed loans that are approved to the corporate sector and the household sector in Serbia. Total new loans granted to corporates, total new loans granted to households, new investment loans granted to corporates and new housing loans granted to households are observed. The observed period is from September 2010 to August 2020. The main goal is to determine whether there is a long-run relation between Euribor and risk premium and the given interest rates, and what is the strength of the given relation. Empirical estimates show that there is a statistically significant impact of Euribor, as well as country risk premium, on lending rates on new households as well as corporate investment FX and FX-indexed loans, with high passthrough coefficients. For the total new corporate FX and FX-indexed loans we also included nonperforming loans as explaining variable which is shown to be statistically significant and whose fall also influenced the fall of lending rates on these loans.
