Currency war, also known as competitive devaluations, is a condition in international affairs where countries seek to gain a trade advantage over other countries by causing the exchange rate of their currency to fall in relation to other currencies. As the exchange rate of a country's currency falls, exports to other countries become more competitive, and imports into the country become more expensive. Both effects benefit the domestic industry, and thus employment, which receives a boost in demand from both domestic and foreign markets. However, the price increases for import goods are unpopular as they harm citizens' purchasing power; and when all countries adopt a similar strategy, it can lead to a general decline in international trade, harming all countries.
