Bank rate

Indian Economy glossary

Topic: Banking, Credit Creation and Monetary Policy · NCERT: Class 12, Ch 3 "Money and Banking"

Meaning

Bank rate is the interest rate at which the RBI lends money to commercial banks, or rediscounts their bills (buys their bills of exchange before they are due), without taking securities as collateral under a repo deal.

  • In theory, a higher bank rate makes bank credit (loans) costlier across the economy, and a lower bank rate makes it cheaper.
  • In India today, the bank rate is not an active policy lever. It is aligned with the MSF rate (Marginal Standing Facility, the emergency overnight borrowing window for banks). It is used mainly to calculate penal charges, which are fines when banks fall short on their required reserves.
  • Current level: bank rate = MSF = 5.50% (August 2026) [2].

Explanation

How the bank rate works (the textbook chain)

  • The bank rate is a quantitative tool, meaning a general tool. It changes the cost of credit in the whole economy and does not target any one sector.
  • When the RBI raises the bank rate:
  • Borrowing from the RBI costs banks more.
  • Banks charge higher interest on their own loans.
  • People and firms borrow and spend less.

  • Demand cools, and so do prices.

  • When the RBI cuts the bank rate, the same chain runs the other way and money supply rises.

  • Rediscounting: a bank holds a bill of exchange (a written promise by a buyer to pay a fixed sum on a future date). The bank can sell this bill to the RBI before the due date to get cash now. The discount the RBI charges on it is linked to the bank rate.

Why it lost its role as the main lever

  • Since 2011, the repo rate (the rate at which the RBI lends to banks for a short time against securities that the bank promises to buy back) has been the single policy rate.
  • The Monetary Policy Committee (MPC) sets the repo rate. The bank rate simply moves with the MSF rate, which is set at repo + 25 bps [4].

  • 1 basis point (bp) = 0.01 percentage point.

  • So the bank rate now changes automatically whenever the repo rate changes. It no longer sends a separate signal.

  • NCERT outdated: the Class 12 book presents the bank rate as an active lending-rate lever. That is no longer how it works in India.

Where it sits in the LAF corridor

  • The Liquidity Adjustment Facility (LAF) is the RBI's daily system for adding cash to the banking system or taking it out [2].
  • The corridor is the band that keeps short-term market interest rates close to the repo rate. The bank rate is at the top of this band, together with MSF.
Rate (August 2026) Level
SDF (floor) 5.00% [2]
Repo (policy rate) 5.25% [2]
MSF / Bank rate (ceiling) 5.50% [2]
  • Corridor width = 5.50 − 5.00 = 50 bps.

Worked example: why the ceiling rate is costlier

  • A bank borrows ₹1,000 crore for one night.
  • At the repo rate (5.25%): 1,000 × 0.0525 ÷ 365 ≈ ₹0.144 crore ≈ ₹14.4 lakh.
  • At the MSF/bank rate (5.50%): 1,000 × 0.055 ÷ 365 ≈ ₹0.151 crore ≈ ₹15.1 lakh.
  • The extra cost is about ₹0.7 lakh for a single night. That is why banks use this route only in emergencies, and why the rate works as a penalty.

In India

  • Who manages it: the Reserve Bank of India (RBI), set up in 1935.
  • Legal frame of monetary policy: the RBI Act preamble, amended in 2016, sets the goal of "price stability while keeping in mind the objective of growth" [4]. The bank rate is one of the quantitative tools that serve this goal.
  • How it is fixed today: the bank rate is not set separately. It is kept equal to the MSF rate, which is repo + 25 bps [4].
  • Main use today: calculating penal charges when banks fall short on reserve requirements such as the CRR (Cash Reserve Ratio, the share of deposits a bank must keep as cash with the RBI).
  • Latest figure: in August 2026, the MPC voted unanimously to keep the repo rate at 5.25%, with a neutral stance [2]. So the bank rate stays at 5.50% [2].
  • How it has moved with the repo rate:
  • 2019-20 easing: repo cut to 4% by May 2020 (COVID shock).
  • May 2022 to February 2023: repo raised by 250 bps, from 4% to 6.5%.
  • 2025 easing: repo cut from 6.5% to 5.25% by December 2025, a total cut of 125 bps.
  • The bank rate followed each move, because it stays 25 bps above the repo rate.

Don't confuse with

  • Repo rate: this is the policy rate set by the MPC, and the loan is backed by securities that the bank promises to buy back. The bank rate involves no repo collateral and is not the policy signal. Today it simply sits 25 bps above the repo rate.
  • MSF rate: this has the same level as the bank rate (5.50% in August 2026) [2]. The difference is in use. MSF is an actual emergency overnight borrowing window, while the bank rate is used mainly as the reference rate for penal charges.
  • SDF / Reverse repo: these form the floor of the corridor and absorb liquidity. The bank rate is at the ceiling. Since April 2022, the SDF has replaced the fixed-rate reverse repo as the floor.
  • WACR (weighted average call rate): this is the average rate at which banks lend to each other overnight. It is the RBI's operating target [4]. The bank rate is a rate the RBI charges banks, not a market rate between banks.

Prelims Hooks

  • Bank rate = the rate at which the RBI lends to banks or rediscounts their bills without repo collateral.
  • In India, Bank rate = MSF = repo + 25 bps [4]. As of August 2026: SDF 5.00% < Repo 5.25% < MSF = Bank rate 5.50% [2].
  • Trap: the bank rate is not the policy rate. The repo rate has been the single policy rate since 2011, and the MPC sets the repo rate, not the bank rate.
  • The bank rate is used today mainly for penal charges on banks that fall short of their reserve requirements.
  • The bank rate is a quantitative (general) tool, not a qualitative (selective) tool such as margin requirements or moral suasion.
  • Raising the bank rate makes emergency funds costlier, so money supply falls. It is a contractionary move.

Mains Points

  • From many signals to one policy rate:
  • Earlier, the bank rate was a main lending-rate lever.
  • Since 2011, the RBI has used a single policy rate (repo) inside the LAF corridor, and the bank rate has been tied to the MSF.

  • One clear signal, with a narrow 50 bps corridor (SDF 5.00% to MSF 5.50%, August 2026) [2], makes it easier for markets to read the RBI's intent. It also keeps the WACR close to the repo rate [4].

  • A penalty rate as a discipline tool:

  • The bank rate acts as the ceiling and the base for penal charges.
  • This discourages banks from depending on the RBI for emergency cash, and pushes them to manage their own liquidity.

  • Because the bank rate automatically moves with the repo rate, penalties stay in line with the current policy stance. For example, it stays at 5.50% while the repo rate is held at 5.25% with a neutral stance in 2026 [2][3].

  • Rule-based framework (GS-II/GS-III link):

  • The shrinking role of the bank rate is part of India's move to a rule-based system: the MPC under s.45ZB sets one rate, aimed at the CPI 4% ± 2% target under s.45ZA [4].
  • This makes monetary policy more transparent and accountable, and harder to use for other goals.
