How does inflation happen?
Quick answer
Inflation happens when overall demand for goods and services outpaces supply, or when the money supply grows faster than the economy — so more money chases the same goods, and prices rise. Demand-pull: too much spending chasing too few goods pushes prices up.
Step by step
- Demand-pull: too much spending chasing too few goods pushes prices up.
- Cost-push: rising production costs (like oil) raise prices.
- Expanding the money supply too fast can devalue each unit of currency.
- Central banks raise interest rates to cool demand and slow inflation.
