Term hyperinflation Definition: Exceptionally high inflation rates. While there are no hard and fast guidelines, an annual inflation rate of 20 percent or more is likely to get you the hyperinflation title. Some countries in the past have been quite good at creating hyperinflation. An annual inflation rate of 1,000 percent has not been uncommon. On occasion, the trillion percent inflation rate mark has been achieved. (That is, something with a one dollar price tag in early January would have a one trillion dollar price in late December. We're talking serious hyperinflation.)
