What Is It?
Inflation is the gradual increase in prices over time, meaning money buys less than before. Moderate inflation (2% annually) is normal in healthy economies. High inflation erodes purchasing power and destabilizes economies.
Origin
Inflation has occurred throughout history—from Roman coin debasement to Weimar Germany hyperinflation. Modern fiat currencies enable persistent inflation. Central banks now target low, stable inflation as optimal for growth.
Why It Matters
Inflation affects savings, investments, wages, and borrowing costs. It redistributes wealth from creditors to debtors. Understanding inflation helps protect purchasing power through appropriate investments (TIPS, real assets).
Intermediate Level
Market Mechanics
Measured by: CPI (consumer basket), PCE (Fed's preferred), PPI (producer prices). Causes: demand growth, supply constraints, or monetary expansion. Expectations become self-fulfilling. Core inflation excludes volatile food and energy.
How It Behaves
Inflation rises with economic overheating, supply shocks, or excessive money printing. Wage-price spirals can develop. Central banks hike rates to cool inflation. Deflation (falling prices) can trap economies in stagnation.
