GDP, Inflation, and RBI Monetary Policy

1. National Income (GDP, GNP, NNP)

Gross Domestic Product (GDP): The total monetary or market value of all finished goods and services produced within a country's borders in a specific time period (usually a year).

• GNP: GDP + Net Factor Income from Abroad.
• Real vs Nominal GDP: Nominal GDP is calculated at current market prices (includes inflation). Real GDP is calculated at constant prices (a base year) to show actual physical growth without the inflation distortion.
• GDP Deflator: The ratio of Nominal GDP to Real GDP.

2. Inflation

Inflation is the sustained increase in the general price level of goods and services in an economy over a period of time.

• Demand-Pull Inflation: Caused by high demand ("Too much money chasing too few goods").
• Cost-Push Inflation: Caused by an increase in the cost of production (e.g., oil price shocks, wage hikes).
• Measurement: In India, headline inflation is measured by the Consumer Price Index (CPI-Combined). The target is 4% (with a tolerance band of +/- 2%).

3. Reserve Bank of India (RBI) & Monetary Policy

The RBI controls the money supply in the economy to manage inflation and stimulate growth via the Monetary Policy Committee (MPC). Quantitative Tools:

• Repo Rate: The interest rate at which RBI lends short-term money to commercial banks. Lower rate = cheaper loans = more money in economy (stimulates growth, but risks inflation).
• Reverse Repo Rate: The rate at which RBI borrows from commercial banks (to absorb excess liquidity).
• CRR (Cash Reserve Ratio): The percentage of total deposits a bank must park in cash with the RBI.
• SLR (Statutory Liquidity Ratio): The percentage of total deposits a bank must maintain within itself in highly liquid safe assets (like Government Securities).
