Hyperinflation is not an individual event, it is a collection of critical events – a process. Externally, this can be seen through ever-increasing prices, but in the background the process is underway where an established currency loses its usefulness as a means of payment. Hyperinflation has occurred all over the world and at all times – in Germany, Greece and China, as well as in ancient Rome, the 17th century France and the 18th century USA. According to Professor Steve Hanke, there have been 52 hyperinflation’s since 1920.
Philip Haslam goes through the dynamics of hyperinflation in the book When money destroys nations and has Zimbabwe as a case study. A brief of the book can be read here.
