The Bank of Russia purchased 5.5 billion rubles ($70.56 million) worth of Chinese yuan on the domestic market with settlements on June 29, according to data published by the regulator.
The intervention comes as the central bank sets its official exchange rate for June 30 at 77.7539 rubles per US dollar, a marginal increase of 69.28 kopecks compared to the previous fix.
The euro was set at 88.6472 rubles.
The yuan purchase reflects ongoing efforts by the Bank of Russia to manage liquidity and stabilize the ruble amid fluctuating capital flows.
The move adds to a series of foreign currency operations aimed at supporting the domestic currency.
Traders will monitor whether the central bank continues its FX interventions in the coming sessions, particularly as global risk sentiment remains volatile.
