At bit2050.com, we break down the mechanisms, players, and economic factors behind rate setting so you can make smarter financial decisions.

What Are Interest Rates?

An interest rate is the cost of borrowing money, expressed as a percentage of the principal. It applies to loans, mortgages, credit cards, and even savings accounts.

Role of Central Banks

Central banks (e.g., RBI, Federal Reserve) set a policy rate—such as the repo or federal funds rate—to influence economic activity:

• Rate Cuts encourage borrowing and spending.

• Rate Hikes curb inflation by making loans more expensive.

Inflation and Interest Rates

Inflation erodes purchasing power. Lenders demand higher rates when:

• CPI rises above target.

• Borrowers need compensation for expected price increases.

Central banks often target 2–4% inflation, adjusting rates accordingly.

Market Forces and Demand & Supply

Beyond policy rates, market-driven rates arise from:

• Interbank lending: Banks lend reserves at overnight rates.

• Bond yields: Government securities’ yields influence consumer loan rates.

• Liquidity conditions: Excess liquidity can push rates down.

Credit Risk Premiums

Lenders add a risk premium based on borrower creditworthiness. Factors include:

• Credit score

• Debt-to-income ratio

• Loan tenure

Higher risk → higher interest rate.

Global Economic Factors

Global events can sway domestic rates:

• US Fed policy often sets the tone worldwide.

• Capital flows: Foreign investment demand for local debt affects yields.

• Currency movements: Depreciation can trigger rate hikes to defend the currency.

How Rates Affect You

• Mortgages & Loans: EMI size depends on the prevailing rate.

• Credit Cards: Higher base rates translate to larger interest charges.

• Savings & FDs: Deposit rates move in tandem—good news for savers when rates rise.
