IMF currency study shows power of devaluation

Report says global trade is still dominated by the export of goods that sold better after a cut in the exchange rate

A 10% fall in the value of a nation's currency can boost exports by an average 1.5% of GDP, according to a study by the International Monetary Fund that reveals the benefits of a cut in the exchange rate for foreign trade.

Heightening fears that the global economy is likely to suffer a new round of currency wars, the report said global trade was still dominated by the export of goods such as cars and fridges that sold better after a cut in the exchange rate made them cheaper.
