Inflation is the rise in prices for goods and services, measured in percentage terms. As inflation goes up, every dollar buys fewer goods and services. Rapid inflation is the acceleration of prices to the point where it’s moving so fast that the people can’t adjust quick enough to the rise in goods and services. Hyperinflation is an extreme version of rapid inflation, where the nation’s monetary system is essentially failing and people lose complete faith in their country’s currency. An example of hyperinflation is Germany in 1923, where, in just a few months, prices rose 2,500%.
