Lender of last resort
Topic: Banking, Credit Creation and Monetary Policy · NCERT: Class 12, Ch 3 "Money and Banking"
Meaning
Lender of last resort is the central bank's role of lending to a sound bank that faces a sudden cash shortage (a liquidity crisis) when no one else will lend to it. In India, the Reserve Bank of India (RBI) plays this role.
It matters because of fear. If people fear that one bank may fail, they rush to withdraw their money, and that fear can spread to other banks. When the central bank stands ready to lend, it stops the panic before a healthy bank is forced to close.
Explanation
Why a healthy bank can still run out of cash
- Banks keep only part of their deposits as cash.
- Banks lend most of the deposits they receive as loans.
- Only a small share stays with them as cash or as reserves with the RBI.
-
So no bank, not even a healthy one, can repay all its depositors on the same day.
-
Bank run:
- depositors fear a bank may fail, so they all rush to withdraw at once;
- even a healthy bank cannot pay everyone at once;
-
the bank may fail only because of this panic, even though its loans are good.
-
Contagion (the spread of panic): when one bank fails, depositors of other banks also get scared. They start withdrawing too, and the whole banking system can be hit.
How the lender of last resort works
- Step by step:
- A sound bank faces a sudden rush of withdrawals.
- Other banks and markets refuse to lend to it.
- The central bank lends it cash, usually against good collateral (assets such as government securities that the bank pledges as a guarantee).
- The bank pays its depositors, and people calm down.
-
The panic stops and does not spread to other banks.
-
Only the central bank can do this. It issues the currency, so it can always create the cash needed in an emergency. No commercial bank can do this.
- Classic textbook rule (Bagehot's principle): in a crisis, the central bank should lend freely, but only to solvent banks, against good collateral, and at a higher-than-normal (penalty) interest rate. The higher rate makes sure banks use this help only when they truly have no other option.
Liquidity vs solvency: the key line
- Illiquid but solvent bank: its assets are worth more than what it owes, but it cannot turn them into cash fast enough. This bank should get lender-of-last-resort support.
- Insolvent bank: its assets are worth less than what it owes, so it has really failed. Lending more money to it does not fix the problem. It needs restructuring or closure, not simple emergency lending.
- What makes this role more or less needed:
- more panic, bad news or weak supervision → more bank runs → more need for emergency lending;
- strong supervision and enough cash with banks → fewer runs → less need for it.
The cost: moral hazard
- Moral hazard: people take bigger risks when they expect someone else to bear the loss.
- Banks expect the RBI to rescue them.
- So they may lend more carelessly.
-
This makes a future crisis more likely.
-
The answer is to pair it with supervision. The central bank also checks that banks keep enough cash and report their loans, so a rescue is rarely needed.
In India
- Institution: the Reserve Bank of India is India's lender of last resort. This is one of its core central-banking functions, along with issuing currency, acting as banker to the government and to banks, and holding forex reserves.
- Legal basis: the RBI Act, 1934, passed on 5 March 1934, is the statutory basis of the RBI. This means the RBI exists because this law created it [2].
- History: the RBI started working on 1 April 1935 as a shareholders' bank [3]. It was nationalised on 1 January 1949 under the RBI (Transfer to Public Ownership) Act, 1948 [4]. It did central-banking work, including lending to banks, from 1935. The 1949 change was about ownership, not about what it did.
- Link with "banker to banks":
- Banks keep accounts and reserves with the RBI, for example the Cash Reserve Ratio (CRR), which is the share of deposits banks must keep with the RBI.
- The RBI lends to banks in normal times, for example through the repo window. Repo is short-term lending to banks against government securities.
-
Lender of last resort is the emergency form of this same banker-to-banks relationship.
-
Link with the RBI's own buffers:
- Under the Economic Capital Framework, the RBI keeps a Contingent Risk Buffer (CRB), a reserve for sudden shocks, including a financial crisis.
- The Bimal Jalan Committee (2019) set the CRB range at 5.5–6.5% of the balance sheet.
-
The 2025 review widened this band to 4.5–7.5%.
-
Supervision alongside it (Class 10 view): the RBI checks that banks keep enough cash balance. It also makes banks report how much they lend, to whom and at what interest rate. This helps limit moral hazard.
- No figure: there is no published "lender of last resort" figure for India. It is a role, not a measured amount.
Don't confuse with
- Banker to banks: the everyday relationship, such as holding bank reserves, settling interbank payments and routine repo lending. Lender of last resort is only the emergency part of it, used when a bank cannot borrow anywhere else.
- Bailout of an insolvent bank: this rescues a bank whose losses exceed its assets, often with public money. Lender of last resort is meant for banks that are sound but short of cash (illiquid but solvent).
- Ways and Means Advances (WMA): short-term overdrafts from the RBI to governments (the Centre by law, states by agreement) to cover timing gaps. Lender of last resort is lending to banks in a crisis.
- Monetary policy (repo rate changes): here the RBI changes the price of money for the whole economy to control inflation and growth. Lender of last resort targets financial stability during a panic, not the general price level.
Prelims Hooks
- Lender of last resort = the RBI lends to a sound bank facing a liquidity crisis when no one else will lend. It is not meant to save banks that have actually failed (insolvent banks).
- Its main purpose is to stop a bank run from spreading to other banks (contagion).
- Its main risk is moral hazard: banks that expect a rescue may take bigger risks.
- The RBI's statutory basis is the RBI Act, 1934, passed on 5 March 1934 [2]. The RBI began work on 1 April 1935 [3].
- Trap: the RBI did central-banking work, including acting as banker to banks, from 1935, not from 1949. Nationalisation on 1 January 1949 only changed who owned it [4].
- Trap: WMA is lending to governments. Lender of last resort is lending to banks.
Mains Points
- Lender of last resort vs moral hazard (GS-III):
- RBI support stops bank runs and contagion, which protects depositors and the payment system;
- but if banks expect a rescue, they may lend carelessly;
-
so the role must go with strong supervision (cash balances, reporting of loans), and support should go only to solvent banks, against good collateral.
-
RBI surplus vs crisis capacity (GS-III):
- The CRB is the RBI's cushion for shocks such as a financial crisis.
- A lower CRB means a bigger surplus for the government, but a thinner cushion when the RBI has to act as lender of last resort.
-
The band moved from 5.5–6.5% (Jalan, 2019) to 4.5–7.5% (2025 review), which is part of the debate between central-bank independence and the government's revenue needs.
-
Financial stability as a public good (GS-II/III):
- Bank failures hurt small depositors and slow credit to farmers and small firms.
- The RBI's lender-of-last-resort role, together with regulation and supervision, shows why the state keeps a public central bank at the top of the banking system.
