What does devaluation mean?
Devaluation and Depreciation Definition. A devaluation occurs when a country makes a conscious decision to lower its exchange rate in a fixed or semi-fixed exchange rate. A depreciation is when there is a fall in the value of a currency in a floating exchange rate. A currency devalues when its value declines in relation to one or more other currencies. Let's say that on Monday $1 bought five rubles and that today, after the devaluation, it buys 10 rubles (not actual figures). Under this scenario, the ruble has devalued by 50%.
