The Russian ruble (RUB) is the official currency of the Russian Federation. It has been the currency of Russia since the collapse of the Soviet Union in 1991.The ruble is subdivided into 100 kopeks (also written as "kopecks" or "copecks"). The symbol for the ruble is "₽" (Unicode: U+20BD).The Central Bank of Russia is responsible for issuing and managing the ruble. The bank also sets monetary policy and ensures the stability of the currency.In the past, the value of the ruble has been affected by factors such as economic growth, inflation, and government policies. The ruble has also been subject to significant fluctuations in value in recent years due to the influence of global economic conditions and the volatility of oil prices, which is one of the main exports of Russia.The code "RUR" you mentioned is the previous code of the Russian Ruble. The RUR abbreviation is an acronym for the Russian ruble, which was the currency of the Soviet Union and the Russian Federation until 1998. After the collapse of the Soviet Union, the Russian Central Bank stopped using the RUR symbol and started using the RUB abbreviation. After 1998 the ruble was redenominated and that was when the switch of the code was made.So currently the official currency code for the Russian Ruble is RUB, and it is widely used internationally.
