The repo (repurchase) rate is the RBI's primary monetary-policy tool. Raising it makes borrowing costlier and cools inflation; cutting it makes credit cheaper and supports growth. Because most bank loans are now linked to the repo rate, changes pass through quickly to EMIs and deposit rates.

Example
If the RBI raises the repo rate from 6.25% to 6.50%, banks' cost of funds rises and floating-rate loan EMIs typically increase.
