Currency devaluation is a deliberate reduction in a currency's value relative to other currencies. Under a fixed exchange rate, it's an official policy decision. Under a floating rate, it can result from market forces or central bank easing.
Export competitiveness: A weaker currency makes exports cheaper for foreign buyers. China historically kept the yuan undervalued to support export-led growth.
Trade balance improvement: Imports become more expensive, reducing import demand, while exports become cheaper — improving the trade balance.
Debt relief: For countries with domestic debt, devaluation reduces the real value of what they owe (if debts are denominated in local currency).
Imported inflation: More expensive imports raise domestic prices. Oil, food, and machinery priced in dollars become costlier after devaluation.
Lower living standards: Citizens' purchasing power for foreign goods falls. Imported electronics, fuel, and food become more expensive.
External debt burden worsens: If a country has debt denominated in foreign currency (dollars, euros), devaluation makes repayment harder — each unit of local currency buys less foreign currency. This is why emerging market crises often involve both devaluation and debt distress.
Capital flight: If investors expect further devaluation, they move money abroad, accelerating the currency's decline and creating a self-fulfilling crisis.
1997 Asian Financial Crisis: Thailand's baht devaluation triggered contagion across Southeast Asia. Currencies fell 30-50%, economies contracted sharply.
2016 Brexit: The pound fell 15% overnight, raising import prices and squeezing household incomes.
2018 Turkey: The lira lost 40% as political tensions and economic imbalances triggered capital flight.

When multiple countries devalue simultaneously to gain export advantage, the result is competitive devaluation, a zero-sum game where no one gains and all face higher inflation. The 1930s saw competitive devaluations that deepened the Great Depression.
Egypt's pound lost approximately 60% of its value between 2022-2024 under IMF pressure to adopt a floating exchange rate. Nigeria's naira was devalued 40% in 2023 when the central bank unified multiple exchange rates. Both devaluations increased debt service costs.
