Steve Hanke of Johns Hopkins and the Cato Institute talks with EconTalk host Russ Roberts about hyperinflation and the U.S. fiscal situation. Hanke argues that despite the seemingly aggressive policies of the Federal Reserve over the last four years, there is currently little or no risk of serious inflation in the United States. His argument is that broad measures of the money supply lag well below their trend level. While high-powered reserves have indeed expanded dramatically, they have not increased sufficiently to offset reductions in bank money, in part because of requirements imposed by Basel III. So, the overall money supply, broadly defined, has fallen. Hanke does argue that the current fiscal path of the United States poses a serious threat to economic stability. The conversation closes with a discussion of hyperinflation in Iran--its causes and what might eventually happen as a result.
