The official currency of Russia is the Russian Ruble, abbreviated as RUB. The Ruble has undergone several changes and revaluations throughout its history, particularly after the collapse of the Soviet Union in the early 1990s. As one of the oldest currencies still in use today, it plays a crucial role in the Russian economy. The Ruble is subdivided into 100 kopecks, and its value can fluctuate based on various factors, including oil prices and international relations. In recent years, the Russian government has implemented measures to stabilize and strengthen the Ruble amid global economic challenges.
