Deflation

Economic Factors High Relevance

A sustained decrease in the general price level of goods and services over time, resulting in a negative inflation rate and increased purchasing power of money. Typically measured by a declining Consumer Price Index (CPI). Deflation often signals economic weakness as falling prices discourage consumption and can lead to deflationary spirals.

Example

During the Great Depression (1929-1933), the U.S. experienced severe deflation with prices falling approximately 25%. More recently, Japan experienced persistent deflation from the late 1990s through the 2000s. In deflationary environments, investors often hold cash (which gains purchasing power), while debtors are hurt as they must repay loans with more valuable dollars.

Common Confusion

Deflation is not the same as disinflation. Disinflation means inflation is slowing (e.g., from 5% to 3%) but prices are still rising. Deflation means prices are actually falling (negative inflation rate, e.g., -2%). Also, while deflation sounds good for consumers, it often accompanies recession and creates a deflationary spiral where falling prices lead to delayed purchases, reduced demand, business failures, and further price declines.

How This Is Tested

  • Distinguishing deflation from disinflation and understanding that deflation is a negative inflation rate
  • Identifying deflationary risks in economic scenarios with falling prices and weak demand
  • Understanding the deflationary spiral: falling prices lead to delayed purchases, reduced demand, lower production, job losses, and further price declines
  • Recognizing investment strategies during deflation: cash gains purchasing power, debtors are hurt, creditors benefit
  • Understanding policy responses to deflation: expansionary monetary policy, lower interest rates, quantitative easing

Question 4

All of the following are characteristics of a deflationary economic environment EXCEPT

Question 5

An economy is experiencing persistent deflation with the CPI declining 2% annually for three consecutive years. Which of the following statements about this deflationary environment are accurate?

1. Central banks would likely implement expansionary monetary policy to combat deflation
2. Fixed-rate mortgage borrowers benefit as their payment obligations decrease in real terms
3. Retirees living on fixed pension income gain purchasing power
4. Businesses are likely to increase capital investment due to falling equipment costs

💡 Memory Aid

Think of deflation as the "Downward Spiral": Falling prices → consumers delay purchases → demand drops → businesses cut production and jobs → incomes fall → demand drops further → prices fall more. Cash is King in deflation: dollars gain purchasing power. Debtors Destroyed: repaying loans with more valuable dollars hurts borrowers.
