Devaluation is a complex economic process that can significantly impact currency and the overall economic situation in a country. For Russia, this phenomenon has special significance as the country's economy heavily depends on global markets. In times of devaluation, the purchasing power of the national currency changes, leading to an increase in prices for imported goods and services, and it may also provoke a rise in inflation levels. These processes have a substantial effect on business, the financial sector, and the daily lives of citizens.
