Overnight funds are a type of open-ended mutual fund that parks money in overnight securities and provides investor-friendly features. If you are planning to invest your surplus money in a safe place, overnight funds can be the best solution for you.
Overnight funds have become popular, and it is noticeable that a large number of people are heading towards these funds. This blog explains what is overnight funds with an example, their essential features, and how to choose one.
What are Overnight Funds?
Overnight funds are a category of highly liquid debt mutual funds that focus on providing stable returns with minimal risk to investors. These funds invest exclusively in debt securities that mature within a single day, ensuring both safety and predictability.
Fund managers maintain a rolling cycle by reinvesting the proceeds from matured securities into new one-day instruments, keeping the portfolio constantly refreshed. Investors can place buy and redemption orders during trading hours, and the fund manager executes these orders daily.
This structure makes overnight funds an attractive option for conservative investors seeking liquidity, security, and short-term parking of funds.
How Does an Overnight Fund Function?
Since you know overnight funds meaning, let us understand how it works. As per the regulations by the Securities and Exchange Board of India, you can use overnight funds to buy money market products with a maturity date of one day or less. The fund’s portfolio undergoes regular changes as the underlying securities mature, making space for the new ones.
To make consistent turnover, the fund manager replaces overnight maturing debt securities with fresh ones daily. The assets under management (AUM) experience incremental growth because of the interest payments from the securities.
Overnight Funds Example
Let us understand what is an overnight fund using an example to help you understand the concept in depth. Suppose you want to invest INR 1 lakh in an overnight fund having a current Net Asset Value (NAV) of INR 1000 per unit.
Number of fund units you would get:
INR 1 lakh / INR 1000 per unit = 100 units
For instance, the next day, the NAV of the fund increases to INR 1002.
Your investment value is now worth:
INR (100 units x INR 1002) = INR 10,02,200
This shows how overnight funds can generate small but quick returns.
