Repo Rate
Rate at which RBI lends to commercial banks against government securities — primary policy lever.
When the Reserve Bank of India lends short-term funds to banks against government securities, the interest charged is the Repo Rate. A rate cut makes borrowing cheaper for banks → cheaper loans for customers → demand boost. A hike does the opposite, used to cool inflation. This is the single most-discussed monetary policy variable in JAIIB Principles & Practices of Banking.
