Lesson 74 - Inflation vs. Stagflation
Inflation and stagflation are related but different economic conditions. Inflation is a general rise in prices, often linked with strong demand or higher costs. Stagflation is more unusual - it combines high inflation with weak growth and high unemployment. This makes stagflation especially painful because standard tools to fight inflation can make unemployment worse, while tools to fight unemployment can fuel inflation.
What is inflation?
Inflation is the rate at which the average level of prices for goods and services increases over time. Moderate inflation is normal in a healthy economy. It erodes purchasing power, but it also encourages spending and investment instead of hoarding cash. Central banks often target around 2% annual inflation. Too much inflation, however, destabilizes households and businesses.
What is stagflation?
Stagflation occurs when high inflation is combined with stagnant or negative economic growth and high unemployment. This condition is rare because inflation and unemployment usually move in opposite directions. The term became famous in the 1970s, when oil shocks and weak productivity caused economies in the US and Europe to suffer both rising prices and job losses.
Table: Inflation vs. stagflation compared
Graph 1: Inflation vs. unemployment (Phillips curve)
Normally, higher inflation goes with lower unemployment, and vice versa. This relationship is called the Phillips curve.
Stagflation breaks this pattern by showing both high inflation and high unemployment.
Graph 2: US inflation and unemployment in the 1970s
This chart shows how both inflation and unemployment rose in the US during stagflation, breaking the usual trade-off.
Both indicators climbed together during the oil shocks of the 1970s.
Story: The oil shocks of the 1970s
In 1973 and 1979, oil prices spiked after geopolitical conflicts. Energy costs surged, pushing up prices across the economy. At the same time, unemployment rose as companies struggled with costs. Central banks faced a dilemma: raise rates to fight inflation, or cut rates to fight unemployment. This period is the textbook case of stagflation, and it reshaped macroeconomic policy debates.
Why this matters for you
Inflation reduces your purchasing power, but stagflation is worse because it threatens both your income and your savings. In stagflation, job security is weaker and prices still rise. For households, the best defense is strong budgeting, emergency savings, and diversified investments that can hold value during turbulence. Policymakers try to prevent stagflation, but if it returns, its impact will be widespread.
Summary
- Inflation is a rise in prices, while stagflation combines inflation with stagnation and unemployment.
- Stagflation is rare but dangerous because policy tools conflict.
- Charts show the breakdown of the Phillips curve and 1970s stagflation data.
- Households must prepare with savings and diversification.
