# What is inflation? #Inflation is a rise in prices across the economy over time. It makes the #purchasing-power erode across the entire economy over time. Gradual, low and stable inflation is okay - they want predictable prices so they can #plan. **#Hyperinflation** is inflation out of control where a unit of #currency destroys itself to tens of orders of magnitude. Central banks do everything they can to avoid hyperinflation: - banks, retirement funds etc become worthless **#Deflation** sounds good but wages fall, so everything becomes more expensive. Prices stay the same but you purchasing power is eroded just the same. You can go back to the [[Economics main page]]
