Offering a new history of global finance over the past two centuries, and marshaling extensive new data to test established theories of how global currencies work, Barry Eichengreen, Arnaud Mehl, and Livia Chitu argue for a new view, in which several national monies can share international currency status, and their importance can change rapidly. They demonstrate how changes in technology and in the structure of international trade and finance have reshaped the landscape of international currencies so that several international financial standards can coexist. They show that multiple international and reserve currencies have in fact coexisted in the pastupending the traditional view of the British pound´s dominance prior to 1945 and the U.S. dollar´s dominance more recently. Looking forward, the book tackles the implications of this new framework for major questions facing the future of the international monetary system, from whether the euro and the Chinese yuan might address their respective challenges and perhaps rival the dollar, to how increased currency competition might affect global financial stability.

"This book will come to be known as the one that challenged the old, winner-takes-all view of international currency competition and established the new view. Barry Eichengreen and his coauthors present thorough and telling evidence that the historical reality is that multiple currencies play consequential roles in international trade and finance--and that lock-in effects and persistence are not as strong as traditionally assumed. In short, this a must-read for all economists interested in international macroeconomics and finance."--Richard Baldwin, Graduate Institute of International and Development Studies, Geneva
