What Are Night Mutual Funds? A New Way to Park Your Idle Money Overnight

In the ever-evolving world of mutual funds, a new category has caught the attention of smart investors: Night Mutual Funds. These are ultra-short-duration funds designed to park money overnight, offering low-risk returns with high liquidity—ideal for individuals and institutions seeking to earn something extra from idle cash without long-term commitments.
Let’s break down what Night Mutual Funds are, how they work, and why they’re gaining popularity.
What is a Night Mutual Fund?
Night Mutual Funds, also known as Overnight Mutual Funds, are open-ended debt mutual funds that invest in securities with maturity of just one day. That means the underlying instruments mature within 24 hours, making them extremely low-risk.
Investment Cycle:
-
You invest today before a cut-off time (usually 1:30 PM)
-
Your money is deployed in overnight instruments
-
Units are allotted on the same day
-
Funds can be redeemed the next working day
What Do Night Mutual Funds Invest In?
These funds typically invest in:
-
Collateralized Borrowing and Lending Obligations (CBLO)
-
Tri-party Repos (TREPS)
-
Overnight government securities
-
Since these instruments have no interest rate risk or credit risk, night funds are among the safest debt mutual fund categories available.
Returns: What Can You Expect?
While returns from Night Mutual Funds are modest, they are significantly better than a savings bank account, especially for large sums.

Investors wanting ultra-safe short-term parking options

Real-Life Example
Let’s say you sold a stock today and received ₹5 lakhs in your trading account. You plan to reinvest in 2–3 days. Instead of letting it sit idle, you can park that amount in a Night Mutual Fund and potentially earn ₹200–₹300 in just one night—without taking market risk.
Final Thoughts
Night Mutual Funds are a smart, low-risk, and efficient option to park idle cash. Whether you're a retail investor or a business entity, they offer the perfect blend of safety, flexibility, and liquidity.
If you’ve been letting your money sleep in a savings account—it's time to make it work, even if it's just for one night.
