Money Market Tools

About the Money Market

The Money Market is the segment of the financial market where highly liquid, short-term financial assets with a maturity of up to 1 year are traded.

It meets the short-term borrowing and working-capital needs of banks, financial institutions, corporates and the government.
Because of short maturity and high liquidity, its instruments are often called “cash investments” or near-money.
The RBI is the regulator and the main liquidity manager of this market.

Types of Money Market Tools

Type	Nature	Effect on
Quantitative (General)	Control the volume of money and credit in the whole economy	Overall liquidity and interest rates
Qualitative (Selective)	Control the direction / purpose of credit	Specific sectors or uses

A. Quantitative Tools

1.Reserve Requirements: Changing the “Lending Pool”

These tools decide how much of their deposits banks must set aside and cannot lend to customers.

Cash Reserve Ratio (CRR)

The percentage of a bank’s Net Demand and Time Liabilities (NDTL) that must be kept as cash with the RBI.
The bank cannot use this money for lending or investment and it earns no interest.
Under the RBI Act, 1934 (as amended in 2006), the RBI has no statutory floor or ceiling on CRR; it can fix any rate.

When CRR increases	When CRR decreases
Banks keep more money with the RBI	Banks keep less money with the RBI
Less money available for loans	More money available for loans
Can lead to higher interest rates on loans (contractionary)	Can lead to lower interest rates and more lending (expansionary)

Statutory Liquidity Ratio (SLR)

The percentage of NDTL that banks must maintain in safe, liquid assets before lending: cash, gold, and unencumbered G-Secs / State Development Loans (SDLs).
Unlike CRR, SLR is held by the bank itself (not with the RBI) and the bank earns interest on G-Secs.
Statutory ceiling: 40% (Banking Regulation Act, 1949, Sec 24). There is no statutory floor.

High SLR	Low SLR
More funds locked in safe assets	More funds free for lending
Less money for loans to businesses and individuals	Banks can lend more to businesses and individuals

CRR vs SLR at a glance

Feature	CRR	SLR
Held as	Cash with RBI	Cash, gold, G-Secs/SDLs with the bank
Interest earned	No	Yes (on securities)
Primary purpose	Liquidity control	Solvency safeguard + government borrowing support
Statutory limit	None	Max 40%

2.Policy Rates: Changing the “Cost of Funds”

These rates determine how expensive it is for commercial banks to borrow from, or how rewarding it is to park funds with, the RBI. Together they form the Liquidity Adjustment Facility (LAF) framework.

Repo Rate (the main policy rate)

The rate at which banks borrow short-term funds from the RBI by pledging G-Secs as collateral (a repurchase agreement).
When Repo Rate increases: To protect margins, banks pass the cost on by raising lending rates. Loans linked to the External Benchmark Lending Rate (EBLR), which is mostly the repo rate, rise quickly.
When Repo Rate decreases: Banks pass the benefit on by lowering interest rates on home, car and personal loans to stay competitive.

Reverse Repo Rate

The rate at which the RBI borrows money from banks, i.e. the rate banks earn when they park surplus funds with the RBI (against RBI-lent G-Secs).
Higher Reverse Repo Rate: Banks earn more from the RBI, so they lend less to people and businesses.
Lower Reverse Repo Rate: Banks earn less from the RBI, so they are more likely to lend.

Marginal Standing Facility (MSF) and Bank Rate

MSF: An emergency window, introduced in 2011-12, that allows banks to borrow overnight from the RBI when they face a severe cash shortage. Banks can dip into their SLR holdings (up to a limit) for this.
It is a penal rate, set above the repo rate (currently repo + 0.25%).
Bank Rate: The long-term rate at which the RBI lends to banks without collateral requirements. It is aligned with the MSF rate and mainly serves as a reference rate for penalties (e.g. on CRR/SLR shortfalls).

Higher MSF rate	Lower MSF rate
Emergency borrowing becomes expensive	Emergency borrowing becomes cheaper
Banks manage liquidity more carefully	Banks can access funds easily when needed

Standing Deposit Facility (SDF)

Introduced in April 2022. It lets banks park surplus funds with the RBI overnight and earn interest, without providing government securities as collateral.
No collateral needed: The RBI can absorb large amounts of excess liquidity easily, since it is not limited by its own stock of securities.
Higher SDF rate: Banks earn more by keeping money with the RBI, so they may lend less.
SDF as the “floor”: Banks will generally not lend at a rate below the SDF rate, because they can earn that rate safely from the RBI.
SDF is currently the floor of the LAF corridor (replacing the reverse repo in that role).

The LAF Corridor

Component	Role	Position (relative to repo)
MSF Rate	Ceiling	Repo + 0.25%
Repo Rate	Policy (anchor) rate	Mid
SDF Rate	Floor	Repo – 0.25%

3. Open Market Operations (OMOs)

OMOs are the outright buying or selling of Government Securities (G-Secs) by the RBI to manage the amount of liquidity (money) available with banks.

When RBI buys G-Secs from banks	When RBI sells G-Secs to banks
RBI gives cash to banks in exchange for bonds	Banks pay cash to RBI to buy bonds
Banks get more cash	Banks have less cash
More cash means more loans (liquidity injection)	Fewer loans (liquidity absorption)
Bond prices rise, yields fall	Bond prices fall, yields rise

Related terms:

Operation Twist: Simultaneously selling short-term and buying long-term G-Secs, to lower long-term yields without changing overall liquidity.
Market Stabilisation Scheme (MSS): Government securities issued (at the RBI’s request) specifically to absorb excess liquidity, especially from capital inflows. The money is held in a separate government account.
Variable Rate Repo/Reverse Repo (VRR/VRRR): Auction-based, longer-tenor liquidity operations for fine-tuning.

B. Qualitative (Selective) Tools

These tools control where credit goes, not how much credit exists in total.

1 Margin Requirements: Controlling the Down Payment

The central bank fixes the minimum share of the asset’s value that the borrower must pay from their own funds when borrowing against collateral.
Margin = Value of collateral – Loan amount (as a % of collateral).
Higher margin: Borrower must pay more, so there is less borrowing.
Often used to curb speculative lending against stocks, commodities or real estate.

2 Consumer Credit Regulation: Controlling EMIs

The central bank can set the minimum down payment and maximum repayment period for consumer loans.
This controls how easily people can buy expensive goods (cars, appliances) on credit.

3 Rationing of Credit: Limiting Loans

The central bank sets a maximum limit on credit a bank can give to a particular sector or company.
This prevents banks from over-lending to one area and building up sectoral risk.
Example: Caps on exposure to a single borrower or group, and limits on sensitive-sector lending.

4 Moral Suasion: Advising Banks

The central bank talks to and advises banks on how to manage lending, through meetings, letters and guidelines.
It has no legal force; it works on the RBI’s authority and the banks’ goodwill.

5 Direct Action: Taking Action Against Banks

The central bank can penalise banks that break rules or ignore instructions.
This may include monetary penalties, restrictions on business (e.g. on new loans or deposits), or other regulatory action (as under the Banking Regulation Act, 1949).

6 Treasury Bills (T Bills)

T bills are one of the most frequently tested money market instruments in competitive exams, especially regarding their issuance, tenors, and pricing mechanism.
Issuer: Issued exclusively by the Central Government of India. (Exam trap: State Governments cannot issue T-Bills; they issue State Development Loans or Cash Management Bills).
Manager/Agent: The Reserve Bank of India (RBI) issues and manages T-Bills on behalf of the Central Government.
Nature: They are zero-coupon instruments (also known as discount bonds). They do not pay regular interest. Instead, they are issued at a discount to their face value and redeemed at full face value (100%) upon maturity. The investor’s return is the difference between the discounted purchase price and the face value received at maturity.
Risk Profile: Considered virtually risk-free (“risk-free gilt-edged instruments”) because they carry a sovereign guarantee from the Central Government.
Currently, the Government of India issues T-Bills across three standard tenors:

Tenor	Issuance Frequency / Details
91-Day T-Bills	Issued weekly (usually Wednesdays). Most liquid among the three.
182-Day T-Bills	Issued fortnightly (alternate Wednesdays).
364-Day T-Bills	Issued fortnightly (alternate Wednesdays). Longest money-market tenor for T-Bills.
