Understanding Money Supply, Inflation, and Economic Policy
Money Supply Aggregates
Old Aggregates (1977)
- M1: Currency with public + Demand Deposits + Other deposits with RBI.
- M2: M1 + Post office savings.
- M3: M1 + Time deposits (Broad Money).
- M4: M3 + Total post office deposits.
New Aggregates (1998)
- M0: Reserve money (Monetary base).
- NM1: Currency + Current deposits + Demand liabilities of savings + Other deposits with RBI.
- NM2: NM1 + CDs + Short-term term deposits (up to 1 year).
- NM3: NM2 + Long-term deposits (Broad Money).
Wholesale Price Index (WPI)
WPI is an indicator used to determine changes in the price of goods available for wholesale in the market. It calculates changes in commodity prices at selected stages before they reach retailers.
Key Measures of WPI
- Primary Articles: Includes food items, non-food items, and minerals.
- Fuel and Power: Includes prices of petrol, diesel, and electricity.
- Manufactured Products: Includes textiles, machinery, and processed food products.
Calculation Method
WPI is calculated using the Laspeyres Price Index formula with a fixed base year.
Formula: WPI = [Σ(P1 × W) / Σ(P0 × W)] × 100
Consumer Price Index (CPI)
CPI measures the average change over time in the prices paid by consumers for a specific basket of goods and services. It is a key indicator of inflation from the consumer’s perspective and impacts the cost of living directly.
Key Measures of CPI
- Food and Beverages
- Housing, Clothing, and Footwear
- Transportation, Communication, and Health
- Education and Miscellaneous goods
Calculation Method
Like WPI, it uses the Laspeyres formula but focuses on retail prices and quantities.
Formula: CPI = [Σ(P1 × Q0) / Σ(P0 × Q0)] × 100
Real vs. Nominal Inflation
Real Inflation
- Refers to the actual increase in the cost of living.
- Shows the impact on purchasing power.
- Essential goods like housing and healthcare often rise faster than average inflation.
- Standard of living declines if income growth lags behind real inflation.
Nominal Inflation
- The official, unadjusted increase in general price levels.
- Measured via CPI, PPI, and GDP Deflator.
- Used by governments for monetary policy, wage revisions, and pension adjustments.
Causes and Effects of Inflation
Causes
- Demand exceeding supply.
- Rising production costs (wages, raw materials, fuel).
- Excess money supply and easy credit.
- Government deficit financing.
- Supply chain disruptions, natural disasters, or wars.
- Hoarding and speculation.
Effects
- Reduced purchasing power.
- Increased cost of living.
- Adverse impact on fixed-income groups.
- High inflation creates economic uncertainty.
