Which should you use?

Inflation

Inflation is the more common condition; central banks usually aim for a low, steady rate (often around 2%).

Deflation

Deflation is rarer but dangerous — when people delay spending expecting lower prices, it can deepen downturns.

Frequently asked questions

Is deflation good because things get cheaper?
Not usually. Mild falling prices sound nice, but deflation often makes people delay purchases, so businesses earn less and cut wages and jobs — a damaging spiral.
What causes inflation versus deflation?
Inflation usually comes from demand or money supply outpacing available goods; deflation from falling demand or a shrinking money supply. Central banks try to keep prices stable.
Which is worse?
Both are harmful in the extreme. High inflation erodes savings; deflation can freeze spending and deepen recessions. Economists generally prefer low, stable inflation.
