Devaluation
A sudden fall in the value of a currency against other currencies. Strictly, devaluation refers only to sharp falls in a currency within a fixed EXCHANGE RATE system. Also it usually refers to a deliberate act of GOVERNMENT policy, although in recent years reluctant devaluers have blamed financial SPECULATION. Most studies of devaluation suggest that its beneficial effects on COMPETITIVENESS are only temporary; over time they are eroded by higher PRICES (see J-CURVE).
