Answer:
hyperinflation
Explanation:
Hyperinflation is a term in economics that denotes an out-of-control, rise in prices of goods and services . When the inflation rate is rapidly rising, say by more than 50% per month, then it is a case of hyperinflation.
Hence, hyperinflation is an explosive and seemingly uncontrollable inflation in which money loses value rapidly and may even go out of use.
