Devaluation is a downward adjustment to a country's currency value relative to other currencies. It is used by countries with fixed exchange rates as a monetary policy tool. India has devalued the rupee multiple times, such as in 1966 and 1991, to combat trade imbalances and boost exports. Devaluation makes exports cheaper and imports more expensive. This improves the current account balance but also increases prices for imports, hurting consumers and raising inflation. The effects depend on elasticity of demand and supply for exports and imports.
