The currency used in Russia is called the Russian ruble. The ruble is denoted by the symbol "₽" and has been the official currency of Russia since the early days of the country. The ruble is subdivided into kopecks, with one ruble equal to 100 kopecks. Over the years, the value of the ruble has fluctuated due to various economic factors, including oil prices, inflation, and international sanctions. The Central Bank of Russia is responsible for issuing currency and managing monetary policy to ensure the stability of the ruble.
