Money Market Instruments for the TIRM Exam: The Complete 2026 Guide

Money Market Instruments: Your Highest-ROI Chapter for the TIRM Exam

If you are preparing for the IIBF Treasury. Investment Risk Management (TIRM) exam. Money market instruments are the one topic you cannot afford to skim.

Year after year. This chapter delivers a heavy share of marks in the treasury paper. Candidates with crisp conceptual clarity here consistently outscore those who only memorised definitions.

Here is the good news. These instruments are not abstract theory. Bank treasury desks trade them every single working day. Once you see how each one actually works. The exam questions start to feel familiar instead of frightening.

This 2026 guide walks you through every major money market instrument. The mechanics behind each. The RBI framework around them.

The latest developments to carry into the hall. And a ready-reference table for fast revision. Let us get started.

What Is the Money Market? Get the Foundation Right

The money market is the part of the financial system where short-term borrowing. Lending of funds happens. Maturities are typically one year or less. Its core job is to supply liquidity to participants. To help the Reserve Bank of India transmit monetary policy.

The main players in the Indian money market include the following:

• The Reserve Bank of India, as regulator and market maker.
• Scheduled commercial banks and primary dealers.
• Mutual funds, insurance companies and corporates.
• Non-banking financial companies (NBFCs).

Each player either raises short-term funds or deploys surplus cash profitably. For TIRM. Internalise one principle: money market instruments are wholesale.

Institutional tools marked by high safety. High liquidity and relatively lower yields than capital market instruments. Now let us examine each one.

Treasury Bills (T-Bills): The Sovereign Benchmark

Treasury Bills are short-term debt instruments issued by the Government of India through the RBI. They are zero-coupon instruments. That means they are issued at a discount to face value. Redeemed at par. The gap between the issue price and face value is your return.

Types of Treasury Bills

• 91-Day T-Bills: Auctioned weekly, usually on Wednesdays. These are the most liquid and most frequently traded T-Bills.
• 182-Day T-Bills: Auctioned on alternate Wednesdays. They meet medium short-term liquidity needs.
• 364-Day T-Bills: Auctioned on alternate Wednesdays. The longest maturity, often used as a short-term rate benchmark.

T-Bills are sold through RBI auctions. The minimum bid is Rs. 10,000 and in multiples thereof.

Crucially. T-Bills are eligible for the Statutory Liquidity Ratio (SLR). Which makes them very attractive to banks.

Exam anchor: T-Bills carry zero default risk due to the sovereign guarantee. Are the most liquid money market instruments. And serve as the pricing benchmark for other short-term instruments.

Cash Management Bills (CMBs): The Flexible Sovereign Tool

Cash Management Bills were introduced in 2010 as a newer addition to India's money market. The Government of India issues them to bridge temporary cash flow mismatches. Unlike regular T-Bills. CMBs have maturities of less than 91 days. Are issued on an ad hoc basis.

CMBs share the core features of T-Bills. They are zero-coupon, issued at a discount, and carry sovereign backing. The key difference is timing.

CMBs are not part of the regular auction calendar. Are announced separately. Like T-Bills, they are SLR-eligible.

Commercial Paper (CP): The Corporate Short-Term Tool

Commercial Paper is an unsecured, negotiable money market instrument. It is issued as a promissory note by corporates. Primary dealers and certain NBFCs to raise short-term funds. CP lets creditworthy firms diversify funding away from bank credit.

Key Features of Commercial Paper

• Issuer eligibility: Corporates with a minimum net worth of Rs. 100 crore. Primary dealers. And eligible NBFCs and All India Financial Institutions, subject to RBI guidelines.
• Maturity: Minimum 7 days, maximum 1 year.
• Credit rating: A minimum rating (such as A3 or equivalent) from a SEBI-registered rating agency is mandatory for every issuance.
• Denomination: Issued in multiples of Rs. 5 lakh, with a minimum investment of Rs. 5 lakh.
• Nature: Issued at a discount to face value, with no collateral.
• Mode: Issued in dematerialised form through registered Issuing and Paying Agents (IPAs). Typically scheduled commercial banks.

Exam tip: CP is unsecured, so it carries credit risk, unlike T-Bills. This is a classic comparison question. Also note that CP rates track call money rates. T-Bill yields closely. A higher call-rate environment usually pushes CP rates up.

Certificates of Deposit (CDs): The Bank's Negotiable Liability

Certificates of Deposit are negotiable. Unsecured money market instruments issued by scheduled commercial banks. Select All India Financial Institutions against funds deposited for a fixed period.

Unlike an ordinary fixed deposit. A CD is freely transferable. Can be traded in the secondary market.

Key Features of Certificates of Deposit

• Issuers: Scheduled commercial banks (excluding Regional Rural Banks. Local Area Banks) and select AIFIs such as EXIM Bank. NABARD, NHB and SIDBI, within their umbrella limits.
• Maturity: For banks, minimum 7 days to maximum 1 year. For financial institutions, minimum 1 year to maximum 3 years.
• Denomination: Minimum Rs. 5 lakh and in multiples thereof.
• Pricing: Issued at a discount to face value. Or on a coupon basis.
• Form: Issued only in dematerialised form, as per RBI directives.

Critical distinction: CDs and CPs look similar but differ in their issuers. CDs come from banks and financial institutions; CPs come from corporates and non-bank entities. This single point appears in many objective questions. Practise it with our mock tests until it is automatic.

Call Money, Notice Money and Term Money

This segment is where interbank borrowing. Lending happens for very short durations. It is central to day-to-day liquidity management by banks.

• Call Money: Overnight (1-day) borrowing and lending. Surplus banks lend to deficit banks at the call rate.
• Notice Money: Borrowing and lending for 2 to 14 days, agreed between the parties.
• Term Money: Borrowing and lending for 15 days up to 1 year.

The call money market is a pure interbank market in India. Only scheduled commercial banks. Cooperative banks and primary dealers may both borrow and lend.

Mutual funds, insurers and others may only lend, not borrow. The call rate is heavily influenced by the RBI Repo Rate. Acts as the operating target of monetary policy.

Repurchase Agreements: Repo, Reverse Repo and TREPS

A Repurchase Agreement (Repo) is a collateralised short-term borrowing mechanism. One party sells securities to another. Agrees to repurchase them later at a set price. Repos are among the most important money market instruments anywhere. And the RBI uses them actively as a policy tool.

Types of Repos in India

• RBI Repo (Policy Repo Rate): Banks borrow from the RBI against government securities. This is the benchmark borrowing rate. Always carry the latest Repo Rate from the most recent monetary policy into the exam &mdash. Confirm on the latest official RBI notification.
• Standing Deposit Facility (SDF): Banks park surplus funds with the RBI. The SDF has effectively become the floor of the liquidity corridor. Replacing the older reverse repo as the floor since April 2022.
• Market Repos: Bilateral repos between participants such as banks. Primary dealers, mutual funds and insurers, collateralised by eligible securities.
• Tri-Party Repos (TREPS): Repos where a neutral third party. CCIL (Clearing Corporation of India Limited), handles settlement and collateral. TREPS is now the dominant overnight funding instrument in India.

High-yield exam point: CBLO (Collateralized Borrowing. Lending Obligation) was discontinued in November 2019 and replaced by TREPS. Never use the old CBLO term in your answers. Note too that the RBI has widened eligible collateral for market repos to include corporate bonds. Deepening the market.

The LAF Corridor: How the Pieces Fit Together

Money market rates do not float freely. They sit inside the RBI's Liquidity Adjustment Facility (LAF) corridor. Picture three levels:

• MSF (Marginal Standing Facility) sits at the top of the corridor &mdash. The rate at which banks borrow extra funds in a pinch.
• Policy Repo Rate sits in the middle — the central benchmark.
• SDF sits at the bottom &mdash. The floor where banks park surplus cash.

The call money rate generally trades within this corridor. Understanding this structure explains why every other short-term rate moves when the RBI acts. Confirm the exact current MSF. Repo. SDF figures on the latest official RBI notification before your exam.

Latest 2025-2026 Developments You Must Carry to the Exam

Staying current with RBI circulars is what separates good candidates from great ones. Here are the themes most likely to be tested. For all specific figures. Verify on the most recent official RBI/IIBF source.

1. Monetary Policy Stance and Rate Moves

The Monetary Policy Committee (MPC) periodically revises the Policy Repo Rate. Which directly reprices all money market instruments. Know the direction and rationale of the latest move.

And quote the current Repo. SDF and MSF rates as per the most recent policy. Confirm the exact numbers on the latest official RBI notification.

2. Liquidity Framework Refinements

The RBI manages systemic liquidity with a mix of Variable Rate Repo (VRR). Variable Rate Reverse Repo (VRRR) auctions. Plus Open Market Operations (OMOs).

For TIRM. Be clear on the difference between durable liquidity injection (OMOs). Short-term liquidity management (Repo and SDF).

3. Tighter Commercial Paper Guidelines

The RBI has emphasised stronger disclosure norms for CP issuers. Tighter due diligence for Issuing and Paying Agents. Credit-rating monitoring is more stringent. And any rating slip below the threshold must be reported promptly. The aim is better credit transparency in the CP market.

4. TREPS Market Deepening

TREPS has cemented its place as the most active overnight money market segment. With very high daily volumes. The RBI has encouraged broader non-bank participation to diversify liquidity sources.

5. Digital and Regulatory Reporting

The RBI's Centralised Information Management System (CIMS) captures issuance data on CDs. CPs. Improving transparency. CD. CP transactions must be reported within stipulated timelines on the platform managed by FIMMDA/CCIL.

How to Study Money Market Instruments (A Practical Method)

Reading alone will not crack TIRM. Use this simple study loop.

1. Map each instrument on five axes: issuer. Maturity, secured or unsecured, minimum amount, and SLR eligibility. The comparison table below is your template.
2. Master two contrasts: CP versus CD, and Repo versus TREPS. These generate the most questions.
3. Drill numericals: practise T-Bill yield problems in both discount-yield and bond-equivalent-yield form. These are easy marks.
4. Read one RBI policy summary and note the latest Repo. SDF and MSF figures, plus the stance.
5. Test under time pressure with full-length mock tests, then review every wrong answer.

Common Mistakes Candidates Make

• Using "CBLO" instead of "TREPS." CBLO is discontinued. This is an instant mark loss.
• Confusing CP and CD issuers. CP is corporate; CD is bank or financial institution. Mixing them up is the single most common error.
• Quoting stale policy rates. Always carry the latest Repo, SDF and MSF figures. Confirm them on the latest official RBI notification.
• Treating CP as risk-free. CP is unsecured and carries credit risk. Only T-Bills and CMBs are sovereign.
• Ignoring SLR eligibility. T-Bills and CMBs are SLR-eligible; CP and CD are not. Examiners love this distinction.
• Studying instruments in isolation. TIRM frames them inside liquidity risk and interest-rate risk scenarios.

Summary Table: Money Market Instruments at a Glance

How These Topics Are Tested in TIRM

The TIRM paper is concept and case-study based. Money market instruments show up in these formats:

• Definition-based: "Which instrument is issued at a discount by corporates?" Answer: Commercial Paper.
• Comparison-based: "How does a CD differ from a CP in issuer. Maturity?" High-scoring if you know the contrast.
• Calculation-based: T-Bill yield (discount versus money-market yield). Or the effective cost of CP including charges.
• Policy-based: Current Repo and SDF rates. Eligible collateral for repos, or CCIL's role in TREPS.
• Application-based: "A bank has surplus funds for 3 days. Which instrument fits best?" This tests practical understanding.

Connecting Money Markets to Treasury Risk Management

Never study these instruments in a vacuum. In TIRM, questions sit inside liquidity risk and interest-rate risk contexts. A bank that funds long-term assets with short-term CDs or CPs faces refinancing risk. Interest-rate risk &mdash. A classic framing.

Likewise, the mark-to-market value of T-Bills falls when rates rise. That links money market instruments straight to the investment-portfolio section of TIRM. Read these chapters together, and the connections will start to click.

Frequently Asked Questions

What are money market instruments in simple terms?

Money market instruments are short-term financial tools used to borrow or lend funds for up to one year. They include Treasury Bills. Commercial Paper, Certificates of Deposit, call money and repos. They are valued for high safety and high liquidity.

What is the difference between Commercial Paper and a Certificate of Deposit?

The key difference is the issuer. Commercial Paper is issued by corporates, primary dealers and NBFCs. A Certificate of Deposit is issued by banks and select financial institutions. Both are unsecured, negotiable and issued at a discount.

Are Treasury Bills risk-free?

T-Bills carry no default risk. They are backed by the Government of India. They can still face interest-rate (market) risk. Since their value changes with rates. They are the benchmark against which other short-term instruments are priced.

What replaced CBLO in the Indian money market?

TREPS (Tri-Party Repo) replaced CBLO, which was discontinued in November 2019. TREPS is settled through CCIL as the central counterparty. Is now the dominant overnight funding instrument in India.

Which money market instruments are SLR-eligible?

Treasury Bills. Cash Management Bills are SLR-eligible because they are government securities. Commercial Paper and Certificates of Deposit are not SLR-eligible. Always confirm the latest classification on the official RBI notification.

Final Thoughts: Build Clarity, Not Just Memory

Plenty of candidates walk into TIRM with memorised bullets. Walk out disappointed. Because the paper tests application. This chapter looks simple. Yet it rewards those who understand the why behind every feature.

Why is CP unsecured? Because it leans on the issuer's creditworthiness and short tenure. Why does the RBI rely on TREPS?

Because it offers collateralised, transparent, CCIL-guaranteed overnight liquidity. Why do T-Bill rates matter to corporate treasurers? Because they are the risk-free benchmark for all short-term pricing.

Approach your prep with that curiosity, practise with updated mock tests, stay current with RBI circulars, and walk in with confidence. You have got this.
