Currency wars are one of the most destructive actions in the global economy. They lead to inflation, recession and slumps. Currency wars have occurred twice in the last century. Now we stand on the threshold of a new war. Chinese currency manipulation, protracted subsidies to Greece and Ireland, the instability of the Russian ruble - all point to a rapidly growing conflict. The author of the acclaimed New York Times bestseller, James Rickards, analyzes the currency war taking place in the world at the present time, from the point of view of economic policy, national security and historical precedents. It unravels the web of failed systems, misconceptions and arrogance at the heart of global finance, and points to a rational and effective course of action to prevent another crisis.
