Interest Rates

What is Interest Rates?

The cost of borrowing money or the return on lending money, usually expressed as a percentage of the principal amount over a period. It is a key tool for central banks to influence economic activity.

Historical Background

Interest rates have been a fundamental component of financial systems for centuries. Their management by central banks became a primary tool for macroeconomic stabilization in the 20th century, particularly after the Great Depression and the rise of Keynesian economics.

Key Points

10 points
  • 1.

    Policy Rates: Set by the central bank (e.g., Repo Rate, Reverse Repo Rate, MSF in India) to influence the overall interest rate structure in the economy.

  • 2.

    Market Rates: Determined by the demand and supply of funds in financial markets (e.g., bond yields, commercial bank lending rates, deposit rates).

  • 3.

    Nominal vs. Real Interest Rates: Nominal rate is the stated rate; Real rate = Nominal rate - Inflation rate. Real rates reflect the true cost of borrowing or return on saving.

  • 4.

    Impact on Borrowing Cost: Higher interest rates increase the cost of borrowing for businesses (for investment) and individuals (for consumption like housing, auto loans), thereby dampening demand.

  • 5.

    Impact on Savings Incentive: Higher interest rates generally encourage saving as the return on deposits increases.

  • 6.

    Inflation Control: Raising interest rates reduces money supply and credit growth, which helps to curb inflationary pressures.

  • 7.

    Exchange Rates: Higher domestic interest rates can attract foreign capital, leading to an appreciation of the domestic currency.

  • 8.

    Asset Prices: Affects the valuation of bonds (inverse relationship), equities, and real estate by influencing discount rates and cost of capital.

  • 9.

    Types: Fixed vs. Floating, Short-term vs. Long-term, Prime Lending Rate (PLR), Marginal Cost of Funds based Lending Rate (MCLR), External Benchmark Lending Rate (EBLR).

  • 10.

    Interest Rate Transmission: The process by which changes in policy rates by the central bank are passed on to market interest rates and ultimately to the real economy.
