🪙 What Inflation Actually Is
Why your dollar buys less each year, and what actually drives it.
What you’ll learn
- Define inflation, explain how the CPI measures it, and distinguish demand-pull from cost-push causes.Inflation is a broad rise in prices that lowers money's purchasing power, measured by indexes like the CPI. It can be driven by excess demand (demand-pull) or rising production costs (cost-push).
- Explain central-bank inflation targeting and learn from real episodes including 2022 and Weimar hyperinflation.The Fed targets about 2% inflation and raises rates to cool it; U.S. CPI peaked at 9.1% in June 2022. Weimar Germany's 1922-23 hyperinflation shows the danger of unchecked money printing. Mild inflation constantly shapes personal finance.
