What Is the RBI and What Does It Actually Do?

The core role

The Reserve Bank of India (RBI), India's central bank, sits above every commercial bank and NBFC in the system - it doesn't lend to individuals directly, but its decisions shape the interest rates, rules, and stability of the entire banking sector you interact with.

Monetary policy: the repo rate

The RBI's Monetary Policy Committee meets periodically to set the repo rate - the rate at which the RBI lends short-term funds to commercial banks. When the repo rate moves, banks' own borrowing costs move with it, which is why a repo rate change eventually flows through to floating-rate home loan and other EMIs, typically with some lag.

(As of the RBI's August 2026 policy review, the repo rate stood at 5.25%, unchanged for four consecutive reviews - checked as of September 2026; this specific number will move over time as the MPC meets, so treat the mechanism as the lasting takeaway, not this particular figure.)

Regulating banks and NBFCs

The RBI licenses banks and NBFCs, sets capital and reserve requirements, conducts inspections, and can intervene - including placing a troubled bank under restrictions - to protect depositors and financial stability.

Currency and payment systems

The RBI is the sole authority for issuing currency notes in India, and also regulates and oversees the digital payment infrastructure (UPI, NEFT, RTGS, IMPS) that Indian banking runs on today.

Consumer protection

Beyond regulation, the RBI runs its own grievance-redressal mechanism for bank customers - the Reserve Bank - Integrated Ombudsman Scheme - see our companion article for how to actually use it.

The takeaway

Nearly everything that touches how banks operate in India - the rate your loan is priced against, whether a bank is allowed to keep operating, how safely a digital payment reaches its destination - ultimately traces back to a rule the RBI set.
