Monetary Policy Transmission

Monetary policy transmission is the process through which a change in the central bank's policy rate affects market interest rates, credit conditions, spending and inflation. The repo rate is the rate at which the Reserve Bank of India provides short-term funds to banks against eligible collateral. Its effect on aggregate demand is indirect and occurs with time lags.

From the repo rate to bank interest rates

A repo-rate change first influences overnight money-market rates and banks' marginal cost or opportunity cost of funds. Banks then adjust deposit rates, wholesale borrowing rates and lending benchmarks, although the adjustment is neither immediate nor uniform.

• A repo-rate cut generally reduces banks' short-term funding cost and encourages lower rates on new and eligible floating-rate loans.
• A repo-rate increase raises the cost of funds and tends to increase lending and deposit rates.
• Transmission is faster for loans linked to an external benchmark than for fixed-rate loans or loans tied to slower-repricing internal benchmarks.

From bank rates to aggregate demand

Bank-rate changes chiefly affect the consumption and investment components of aggregate demand. A rate cut makes borrowing cheaper, while a rate increase works in the opposite direction.

• Lower loan rates can increase household demand for interest-sensitive goods such as houses and consumer durables.
• Lower financing costs can make more business investment projects profitable and support working-capital borrowing.
• Lower debt-servicing burdens can raise the disposable cash flow of existing floating-rate borrowers.
• Higher rates restrain credit-financed consumption and investment, thereby moderating demand and inflationary pressure.

Why transmission may be incomplete

The final effect depends on banks' balance sheets, market conditions and borrowers' willingness to take credit. Consequently, an identical policy-rate change may produce different lending-rate and demand responses across time.

• Weak bank capital, stressed assets or greater perceived credit risk can limit the expansion of lending.
• Fixed-rate contracts and delayed repricing of deposits can slow the pass-through.
• Low credit demand, abundant banking-system liquidity or competition for deposits can weaken or alter transmission.
• Expectations about future inflation and policy influence how quickly banks and borrowers respond.
