What Is a Reverse Repo (Ters Repo)? Understanding Liquidity Absorption and Money Market Operations

What Is a Reverse Repo (Ters Repo)?

A Reverse Repo, also known as a Ters Repo, is a short-term financial transaction in which one party buys a security and agrees to sell it back later at a predetermined price.

From an economic perspective, a reverse repo is the mirror image of a repo:

The buyer of the security provides cash (acts as a lender)
The seller of the security receives cash (acts as a borrower)
The security serves as collateral

Reverse repos are widely used in money markets and are a key tool in central bank liquidity management.

Key Characteristics of Reverse Repo Transactions

Reverse repos have several defining features that differentiate them from other money market instruments.

1. Short-Term Maturity

Reverse repos usually have maturities of:

Overnight
A few days
Up to several weeks

They are designed for short-term cash placement and liquidity absorption.

2. Collateralized Structure

Reverse repos are backed by high-quality securities such as:

Government bonds
Treasury bills
Central bank securities

Collateral significantly reduces counterparty risk.

3. Fixed Resale Price

The resale price is agreed upon at the start and includes:

Original purchase price
Reverse repo interest (reverse repo rate)

4. Reverse Repo Rate

The reverse repo rate represents the return earned by the cash provider and reflects:

Short-term liquidity conditions
Central bank policy stance
Money market supply and demand

5. Low Risk Profile

Because they are collateral-backed and short-term, reverse repos are considered very low-risk instruments.

How a Reverse Repo Works

A reverse repo involves two linked transactions:

Initial Purchase
The investor buys securities and provides cash.
Resale Agreement
The investor agrees to sell the securities back at a later date at a higher price.

Example:

Purchase price: $1,000,000
Reverse repo rate: 3.5% (annualized)
Term: 7 days

At maturity, the investor sells the securities back for $1,000,672, earning interest.
