What it is
Currency devaluation occurs when a country's government or central bank intentionally lowers the official value of its currency against a foreign currency or a basket of currencies. This action is typically taken to make exports cheaper and more competitive, thereby boosting a country's trade balance and economic growth. It also makes imports more expensive, potentially curbing demand for foreign goods and reducing a trade deficit.
While often associated with fixed exchange rate regimes, news reports also use "devaluation" informally to describe significant depreciation under floating exchange rates, especially when driven by policy. For example, a central bank lowering interest rates or engaging in quantitative easing can indirectly lead to its currency weakening. Investors track devaluation as it affects the returns on foreign investments, the cost of imported goods, and a country's inflation outlook.
Why it matters
Devaluation affects the cost of imported goods, the value of international investments, and can influence domestic inflation, impacting your purchasing power.
