The Belarusian ruble, rouble or rubel is the official currency of Belarus. It is subdivided into 100 kopecks.
The exchange rate of the Belarusian ruble is determined based on a basket of currencies consisting of the Russian ruble, the US dollar and the renminbi. The euro was part of said currency basket but was excluded in December 2022 due to a decrease in the volume of trade between Belarus and the European Union.Wikipedia
