THE CONQUEST OF WORLDWIDE INFLATION: CURRENCY COMPETITION AND ITS IMPLICATIONS FOR INTEREST RATES AND THE YIELD CURVE

In the United States and in virtually every country around the world, inflation has declined, and in most countries dramatically so. In addition, the volatility of inflation and expectations of future inflation have also fallen significantly. I will call these changes experienced around the globe the conquest of worldwide inflation. I will begin by providing a few facts about the substantial improvement of inflation during roughly the past decade compared with the quarter century that preceded it. I will then try to understand why this remarkable decline in inflation has taken place. In particular, I argue that globalization, deregulation, and financial innovation, in part spurred by experiences of high inflation in the 1980s, have fostered currency competition that has led to improved central bank performance and, hence, the recent conquest of worldwide inflation. Friedrich Hayek (1976) had long ago advocated permitting greater competition among currencies, arguing that there would be a race to the top rather than a race to the bottom. Regardless of what one might think of Hayek’s policy proposals, technological change in a globalized and competitive marketplace, I believe, has increased competition among currencies issued by central banks. The increased competition among currencies has changed the ability and the incentives of governments and central banks to pursue high-inflation policies. As I will argue, such changes have allowed improvements in central bank independence, governance, and credibility, thereby leading to better inflation outcomes. In addition,
