Inflation is one of the most talked-about economic issues because it affects everyone—from students buying coffee to businesses planning investments. This unit covers what inflation really means, why it happens, its effects on the economy, and how governments try to control it. It also introduces related concepts like deflation and stagflation, and explains various policy tools used to manage price stability.

What is Inflation?
Inflation refers to a sustained rise in the general price level of goods and services in an economy over time. It means that each unit of currency buys fewer goods and services—so the purchasing power of money falls.
A moderate level of inflation is considered normal in a growing economy. However, when prices rise too quickly, it can hurt consumers, especially those with fixed incomes.
Types of Inflation
Inflation can take several forms depending on its speed and cause:
Creeping Inflation: Slow and steady price rise (1–3% annually). Usually harmless.
Walking Inflation: Moderate rise (around 3–10%). Can start becoming a concern.
Galloping Inflation: Rapid increase in prices (double-digit or higher).
Hyperinflation: Extremely high and uncontrollable rise in prices—often seen in economic crises.
Other categories include:
Demand-Pull Inflation: Occurs when demand exceeds supply in the economy. For example, during festival seasons, if too many people chase limited goods, prices rise.
Cost-Push Inflation: Happens when production costs increase, such as wages or raw materials, leading businesses to raise prices.
Causes of Inflation
Several factors can lead to inflation, including:
Increased consumer demand
Higher wages and input costs
Supply chain disruptions
Excessive money supply injected by central banks
Government deficit spending
Each of these triggers a chain reaction that pushes prices upward in the economy.
Effects of Inflation
Inflation has both positive and negative effects:
Negative effects:
Reduces purchasing power
Hurts savers and people on fixed incomes
Increases uncertainty in business planning
Distorts investment and savings decisions
Positive effects (in moderation):
Encourages spending and investment (people avoid holding cash)
Helps reduce the real burden of debt
Signals economic growth if wages rise proportionately
What is Deflation and Stagflation?
Deflation is the opposite of inflation—a fall in general price levels. It might sound good, but it often indicates weak demand and slowing economic growth. Businesses earn less and may lay off workers.
Stagflation is a rare and difficult situation where the economy faces high inflation, high unemployment, and stagnant growth all at once. It’s challenging to fix because the usual tools to reduce inflation can worsen unemployment.
Controlling Inflation – Policy Tools
Governments and central banks use several tools to maintain price stability, including:
Monetary Policy (by the Central Bank):
Raising interest rates to reduce borrowing
Reducing money supply through open market operations
Increasing reserve requirements for banks
These actions slow down spending and investment, helping reduce inflationary pressure.
Fiscal Policy (by the Government):
Reducing government spending
Increasing taxes to control demand
By withdrawing money from the economy, fiscal tools reduce excess demand.
Supply-Side Measures:
Improving production efficiency
Investing in infrastructure
Reducing production bottlenecks
These increase supply, helping match or exceed demand, which stabilizes prices.
