Inflation is the sustained increase in the general price level of goods and services in an economy over time, leading to a decline in the purchasing power of money. It means that, on average, prices rise, and each unit of currency buys fewer goods and services than before.
Key Characteristics of Inflation:
- Rising Prices – Measured by indices like the Consumer Price Index (CPI) or Producer Price Index (PPI).
- Erosion of Purchasing Power – Money loses value; people need more of it to buy the same things.
- Demand-Pull vs. Cost-Push Causes – Can be driven by high demand (demand-pull) or rising production costs (cost-push).
- Central Bank Role – Institutions like the Federal Reserve or ECB use interest rates & monetary policy to control inflation.
Main Causes of Inflation:
- Demand-Pull Inflation – When demand for goods/services exceeds supply (e.g., post-pandemic spending surges).
- Cost-Push Inflation – When production costs (wages, energy, materials) rise, forcing price hikes.
- Monetary Inflation – Too much money supply chasing too few goods (e.g., excessive money printing).
- Built-In Inflation – When workers demand higher wages, leading to a price-wage spiral.
Effects of Inflation:
Positive:
- Encourages spending/investment (if mild, e.g., 2% target).
- Reduces real debt burden (if wages rise with prices).
Negative:
- Hurts savers (cash loses value).
- Creates uncertainty, distorting long-term planning.
- Can lead to hyperinflation if uncontrolled (e.g., Zimbabwe, Venezuela).
How Is Inflation Measured?
- CPI (Consumer Price Index) – Tracks price changes in a basket of consumer goods.
- Core Inflation – Excludes volatile items (food, energy) for a stable trend.
- PPI (Producer Price Index) – Measures wholesale price changes before they hit consumers.
Current Example (2024):
Many countries saw inflation spikes post-COVID due to supply chain disruptions and stimulus spending. The U.S. Federal Reserve raised interest rates aggressively to curb it, while Argentina struggled with 100%+ inflation in 2023.
Conclusion:
Inflation is a natural economic phenomenon but must be managed carefully. Moderate inflation (2-3%) is healthy, but high or hyperinflation can destabilize economies. Central banks use monetary policy (interest rates, quantitative tightening) to keep it in check.
