What is Deflation?
Deflation is a sustained decline in the general price level of goods and services in an economy, typically occurring when demand falls below supply over an extended period.
Definition
Deflation refers to a prolonged decrease in overall prices, increasing the real value of money and debt, and often reflecting weak economic activity, falling demand, or contraction in the money supply.
Key Takeaways
- Represents a sustained fall in the general price level.
- Increases the real purchasing power of money but raises the real burden of debt.
- Often associated with weak demand, high unemployment, and reduced investment.
- Can create self-reinforcing economic downturns if left unaddressed.
Understanding Deflation
Deflation occurs when aggregate demand consistently lags behind aggregate supply, leading businesses to lower prices to stimulate sales. While falling prices may seem beneficial to consumers in the short term, deflation can have damaging long-term economic effects.
As prices fall, consumers and businesses may delay spending in anticipation of even lower prices, reducing revenue and profits. This behaviour suppresses investment and hiring, reinforcing economic contraction.
Deflation also increases the real value of existing debt, making it harder for households, businesses, and governments to service obligations. This dynamic can weaken financial systems and slow economic recovery.
Importance in Business or Economics
- Influences monetary policy decisions and interest rate settings.
- Affects corporate pricing strategies, profitability, and investment planning.
- Raises default risk by increasing real debt burdens.
- Can destabilise financial systems if prolonged.
Types or Variations
- Demand-Driven Deflation – Caused by weak consumer and business demand.
- Monetary Deflation – Triggered by contraction in money supply or credit.
- Debt Deflation – Falling prices increase real debt levels, amplifying financial stress.
