The National Bank of Tajikistan (NBT) collects rubles sent by labour migrants from Russia, as well as currencies entering the country from exports and foreign direct investment, and then buys dollars in Russia with them.
According to the
National Bank of Tajikistan, commercial banks must sell 50% of the received ruble remittances to the NBT. It, in turn, according to unofficial data, exchanges this money in Russian banks for dollars. The National Bank neither confirms, nor denies this information.
Since the country receives most of its currency from the export of labour resources, the exchange rate of the national currency, the somoni, is highly dependent on the migrants' money.
