When you have surplus funds that you'll need within a few months or a year, keeping them in a regular savings account means earning minimal returns. This is where short-term mutual fund options come into play. Three popular choices dominate this space: liquid funds, overnight funds, and arbitrage funds. Each serves a specific purpose and understanding their mechanics can help you make better investment decisions.
Understanding Liquid Funds
Liquid funds invest in very short-term debt instruments with maturities up to 91 days. These include treasury bills, commercial papers, and certificates of deposit. Fund managers focus on high-quality securities issued by governments and top-rated corporations to minimize credit risk.
The key advantage is that liquid funds typically offer better returns than savings accounts while maintaining relatively easy access to your money. Most fund houses allow redemption requests that are processed within one business day, with some offering instant redemption facilities for amounts up to certain limits.
However, liquid funds are not entirely risk-free. They carry interest rate risk and credit risk, though both are generally low given the short maturity profile. Returns typically range between 6-7% annually in the current interest rate environment, though this fluctuates based on prevailing rates.
What Are Overnight Funds?
Overnight funds are the most conservative option among debt mutual funds. They invest exclusively in securities with overnight maturity, meaning these instruments mature the very next day. This could include overnight reverse repos, tri-party repos, and similar money market instruments.
The ultra-short maturity profile makes overnight funds extremely low-risk from both interest rate and credit perspectives. Since the securities mature daily, there's virtually no sensitivity to interest rate changes. The fund manager reinvests the matured amount into fresh overnight securities each day.
Returns on overnight funds are modest, usually slightly better than savings bank interest rates, ranging between 5-6% annually. The trade-off for this safety is lower potential returns compared to liquid funds. These funds suit investors who prioritize capital protection above all else and need parking space for a few days to a few weeks.
The Arbitrage Fund Alternative
Arbitrage funds operate differently from liquid and overnight funds. Instead of debt instruments, they exploit price differences between the cash and derivatives markets. Fund managers simultaneously buy stocks in the cash market and sell equivalent futures contracts, pocketing the spread between the two prices.
From a taxation standpoint, arbitrage funds are classified as equity funds because they maintain equity exposure, even though the arbitrage strategy aims to neutralize market risk. This classification offers a significant tax advantage: gains held for more than one year qualify for long-term capital gains tax at just 12.5% on gains exceeding Rs 1.25 lakh annually, with no tax on gains below this threshold. Short-term gains are taxed at 20%.
In contrast, liquid and overnight funds are debt funds, where gains are added to your income and taxed at your applicable slab rate regardless of holding period.
Returns from arbitrage funds depend on the arbitrage spread available in the market, which tends to widen during volatile periods and narrow during calm markets. Historically, these funds have delivered returns in the 6-7% range annually, sometimes higher.
Making the Right Choice
Your selection should depend on your investment horizon, risk appetite, and tax situation.
- Choose overnight funds when you need to park money for very short periods (days to a few weeks) and want maximum capital safety
- Opt for liquid funds when your horizon extends from a few weeks to 3-6 months and you can accept minimal risk for slightly better returns
- Consider arbitrage funds when your timeline is 6-12 months, you fall in higher tax brackets, and want equity taxation benefits while maintaining low market risk
Tax considerations become crucial as your investment amount and tax bracket increase. Someone in the 30% tax bracket benefits more from arbitrage funds for 12-month parking compared to liquid funds, assuming similar pre-tax returns.
Also evaluate factors like exit loads, expense ratios, and the track record of the fund house. Most liquid and overnight funds don't charge exit loads if held beyond 7 days, while arbitrage funds typically have no exit loads.
