Overnight funds have gained substantial traction in the Indian financial ecosystem. As the name suggests, an overnight fund is a type of debt mutual fund that offers high liquidity and earns income on surplus funds invested for a very short term, typically a single business day. Thus, many investors park their money in overnight funds with the aim of a reasonable return on the very next business day. This is made possible as these funds invest mostly in overnight securities that have a maturity period of one day.

However, like with any other investment avenue, investing in an overnight fund is associated with certain risks. In this article, we will take a closer look at the risks and other measures associated with overnight funds.

What are the risks associated with overnight funds?

Overnight funds are amongst relatively stable mutual funds in the market. However, no mutual fund investment is completely free from risks, so it’s important to keep in mind the following risks of overnight funds.

Default risk: One might assume that an investment horizon of just one day would mitigate most risks. However, an overnight fund isn’t completely free from default risks. Default risk arises when the counterparty – often a bank or financial institution – fails to fulfil its payment obligation the next day. The good news is that the default risk in overnight funds is considerably lower compared to other short-term and long-term debt funds. Given the brief maturity period, the creditworthiness of the issuer is paramount, and thus overnight fund managers usually invest in high credit-rated securities.

Interest rate risk: Another factor to consider is the interest rate risk. As overnight funds invest in securities maturing in a day, the fluctuation in interest rates directly impacts the Net Asset Value (NAV) of the fund. However, due to the very short investment horizon, the interest rate risk in an overnight fund is minimal compared to other debt funds.

Liquidity risk: Liquidity risk emerges when a fund faces difficulties in selling its assets without causing a significant movement in its price. In the case of overnight funds, the liquidity risk is again minimised. As the securities are held for just one day and are usually in high demand, it’s less likely for a liquidity issue to crop up.

Overnight funds: A relatively stable option among mutual funds

Given the risks detailed above, the following might sound counterintuitive, but overnight funds are among the relatively stable mutual funds to invest in. This is because the risks involved in overnight fund investments are comparatively lower than in other categories of mutual funds. Their one-day maturity means they are less exposed to credit and interest rate volatilities. These funds can be a suitable choice for conservative investors looking for a relatively stable avenue to park their surplus funds temporarily.

Things to consider when making an investment in overnight funds

Investment goals: Before you invest in an overnight fund, it’s important to assess whether it aligns with your financial goals. Overnight funds are better suited for those aiming for low impact on capital and quick potential returns over a short period.

Selecting the right fund and AMC: Once you decide to invest in an overnight fund, you must choose a suitable Asset Management Companies (AMCs) and their offerings. Assess the fund's portfolio, credit quality of its investments, and the reputation of the AMC. While overnight funds are relatively stable, the credibility of the AMC plays a crucial role in ensuring the quality of your investment.
