Abstract
The article deals with the hypothesis of the dependence of the national currency of Kazakhstan on the Russian currency and the determinism of the dynamics of the currency market of Kazakhstan processes taking place in the Russian currency market in connection with the membership of the EAEU. To verify this hypothesis, the author considers the main arguments of its supporters using data on other EAEU countries, including the intensity of foreign trade cooperation, the scale of foreign exchange markets as a factor of their vulnerability to speculative attacks, as well as changes in the balance of payments. In the course of the analysis, the thesis about the determinism of the national currency markets of the EAEU countries by the processes associated with the change of the Russian ruble exchange rate was not confirmed.
