Hyperinflation.
In plain English
One widely used accounting threshold treats inflation above 50 percent per month as hyperinflation, a pace that compounds to enormous annual figures. It is almost always the result of a government financing large deficits by creating money, often alongside war, a collapse in tax collection, or a loss of access to credit. Once people expect it, velocity spikes because holding cash becomes a guaranteed loss, which accelerates the process. Ending it usually requires a credible break: a new currency, an independent central bank, or fiscal changes that remove the need to print. Savings held in the local currency are typically destroyed.
01Why it matters
Hyperinflation wipes out cash savings and fixed pensions within months, and it is the clearest example of why the credibility of a currency issuer matters to ordinary households.
02The math, step by step
At 50 percent monthly inflation, something costing 100 units costs 150 after one month, 225 after two, and about 1,139 after six months, which is 100 times 1.5 to the sixth power. A full year of that turns 100 into roughly 13,000.

03What this is NOT
High inflation is painful, but the currency still works as a store of value over weeks. Hyperinflation breaks that function entirely, so contracts, wages, and pricing shift to a foreign currency or to daily repricing. The difference is a change in kind, not just in degree.
