You will be able to answer any CBLO money market question in your exam with confidence.

What Is CBLO in the Money Market?

The Collateralized Borrowing. Lending Obligation (CBLO) was a money market segment operated by the Clearing Corporation of India Ltd (CCIL). In simple words. It let financial institutions borrow. Lend short-term funds against securities pledged as collateral.

Think of it like a secured overnight loan desk for big institutions. A borrower needed cash for a day or a few days. A lender had spare cash to park safely. CBLO matched them. But only after the borrower deposited eligible securities as a guarantee.

In purpose and design. CBLO was very close to the call money market. The big difference was collateral. Call money is unsecured. CBLO was fully collateralized, which made it safer for lenders.

Why Institutions Needed CBLO

Financial institutions constantly need liquidity — ready cash to settle daily transactions. They have a few options to raise short-term funds:

• RBI Repo facility — typically one-day loans to scheduled commercial banks.
• Call Money Market — loans from one day to fourteen days, unsecured.
• CBLO Market — short-term funds against collateral. Open to a wider set of players.

So CBLO filled a clear gap. It gave quick. Short-term money to entities that were shut out of. Or restricted in, the call money market.

How a CBLO Worked (Step by Step)

The mechanics are exam-favourite material, so let us break them down cleanly. CCIL, alongside the Reserve Bank of India (RBI), operated the CBLO market.

1. Deposit collateral: The borrower deposited eligible securities (such as Central Government securities. Including Treasury Bills) with CCIL.
2. Place orders: Borrowers. Lenders submitted their borrowing and lending orders into the system.
3. Order matching: CCIL matched borrowing and lending orders by amount and rate.
4. Funds transfer: The lender released funds; the borrower received the money.
5. Repayment: On a specified future date. The borrower repaid the debt. The lender was entitled to receive the money back.

A neat feature: just like bonds. CBLOs were purchased by lenders and sold by borrowers, with interest. A lender could even transfer their claim to another party in exchange for value received. Maturities ranged from overnight to one year, always with full collateralization.

Who Were the Participants in the CBLO Market?

The core idea: CBLO welcomed institutions that had no access or restricted access to the inter-bank call money market. Yet players already active in call money could join CBLO too.

Eligible members for CBLO membership included:

• Nationalized Banks
• Private Banks
• Foreign Banks
• Co-operative Banks
• Insurance Companies
• Mutual Funds
• Primary Dealers and Bank-cum-Primary Dealers
• NBFCs
• Corporates
• Provident / Pension Funds

To transact, these institutions first had to obtain a CBLO membership. Membership was the entry ticket to the market.

The CBLO Instrument and Trading System

The CBLO itself was the instrument that gave the market its name. It was a discounted instrument in electronic book-entry form. With a maturity ranging from one day to one year.

For trading. CCIL provided a Dealing System through the Indian Financial Network (INFINET). The Negotiated Dealing System (NDS). Members borrowed or lent funds against eligible securities.

Eligible securities included Central Government securities (such as Treasury Bills). Other securities specified by CCIL. Borrowers deposited the required securities with CCIL. The system matched orders. And borrowers paid interest to lenders as per the bid.

CBLO Auction Market vs Normal Market

CBLO operated through two windows — an auction market and a normal market. Here is the practical difference in one glance.

How the auction worked: Members willing to lend submitted bids. Amount plus rate — during the open session. Lenders could alter or cancel their bids while the window stayed open.

Borrowers, however, could not edit their submitted offers. When the session closed at 12:15 PM IST. The system matched bids and offers.

And successful borrowers and lenders were notified.

Members who missed out in the auction could still try the CBLO normal market. Matched deals in both markets settled on a T + 0 basis — same-day settlement.

Always confirm exact lot sizes, timings, and settlement cycles on the latest official IIBF / CCIL notification, as operational parameters can change over time.

Important Update: CBLO and the Tri-Party Repo (TREPS)

Here is the part most legacy notes leave out. And it is exactly where a sharp examiner can catch you.

CBLO has been discontinued. CCIL replaced it with the Tri-Party Repo (TREPS). A more modern, internationally aligned collateralized money-market product. The Tri-Party Repo carries forward the same core idea — fully collateralized. CCIL-guaranteed short-term funding — under an updated framework.

For your exam, remember both points:

• Conceptually. CBLO taught the model of collateralized borrowing. Lending in the money market.
• Currently, that role is played by the Tri-Party Repo (TREPS).

Because exact transition dates and rules can be tested precisely. Always confirm the current status on the latest official IIBF / RBI / CCIL notification before the exam.
