Phase One: is “the rise”. The IMF also calls this “the extraordinary acceleration phase” which is the lead-up to the hyperinflation. IMF actually terms it “the path toward hyperinflation”, but given that they define that as an annual inflation rate of greater than 50% but under 500%, an uncredentialed, non-economist observer might describe that as already being hyperinflation.
Phase Two: is the actual hyperinflation proper.
Wheelbarrows of money, burning banknotes in the oven (or more tragically, sticking your head in there).
In one well storied example from Weimar Germany, an emigre fighting to retrieve his savings from a German bank was finally paid out – via a cheque mailed to him in America. The stamp on the envelope cost more than the value on the cheque made out to him.
Over the eighteen 20th century hyperinflations covered in the IMF paper, the average inflation rate here, according to the IMF study was 2,912% and the median duration was four years – this “explosive” phase is usually over in about two years.
Phases Three and Four are the second stage of a hyper inflationary event: “disinflation” – where the annual inflation rate plummets to somewhere between 50% and 500% and lasts another six years on average – and finally the “stabilization” phase, where inflation remains under 50% per year for at least three years.
