Arbitrage Funds
Arbitrage funds are hybrid mutual funds that buy shares in the cash market and sell matching futures to lock in the price difference, aiming for low-risk returns with equity-oriented taxation.
What Are Arbitrage Funds?
An arbitrage fund is a hybrid mutual fund that earns returns mainly from price differences of the same stock in two markets: the cash (spot) market and the futures (derivatives) market. The fund buys shares in one and sells an equal quantity in the other, locking in the gap between the two prices.
Under SEBI's categorisation rules, an arbitrage fund must follow an arbitrage strategy and invest at least 65% of total assets in equity and equity-related instruments. Because nearly all of this equity is hedged, the fund carries very little stock market risk, even though it holds a lot of shares.
Investors usually come across arbitrage funds when looking for somewhere to park money for a few months, as an alternative to liquid funds or short-term deposits, especially because of their tax treatment.
How Do Arbitrage Funds Work?
- Spot a price gap. A stock trades at ₹1,000 in the cash market and its one-month future trades at ₹1,006. The ₹6 difference reflects the cost of carrying the position until expiry.
- Take opposite positions. The fund buys the shares in the cash market and sells the same quantity of futures.
- Hold until expiry (or until the gap closes). At expiry, the futures price and cash price converge.
- Lock in the spread. Whatever the stock does, the gain on one leg offsets the loss on the other, leaving roughly the original ₹6 (before costs).
- Roll over. The fund repeats this across many stocks every month.
- Park the rest safely. The non-arbitrage portion goes into debt. Under SEBI's February 2026 circular, an arbitrage fund's debt exposure is limited to government securities with maturity of less than one year and repo of government bonds, and no investment in InvITs is permitted.
If arbitrage opportunities are scarce, the fund may hold more debt or cash for defensive reasons, as stated in its Scheme Information Document (SID).
Practical Example
The fund buys 100 shares at ₹1,000 (cost ₹1,00,000) and sells 100 one-month futures at ₹1,006.
Case A: Stock falls to ₹950 at expiry
- Cash leg: (950 − 1,000) × 100 = −₹5,000
- Futures leg: (1,006 − 950) × 100 = +₹5,600
- Net = +₹600
Case B: Stock rises to ₹1,050 at expiry
- Cash leg: (1,050 − 1,000) × 100 = +₹5,000
- Futures leg: (1,006 − 1,050) × 100 = −₹4,400
- Net = +₹600
In both cases, the profit is ₹600 on ₹1,00,000, or 0.6% for the month, regardless of the stock's direction. If similar spreads were available every month, a simple (non-compounded) estimate would be 0.6% × 12 = 7.2% a year. In practice, spreads change every month and depend on market conditions, so actual returns vary.
Why Are Arbitrage Funds Important?
- Low market risk: Hedged positions mean the fund's NAV usually moves only slightly day to day.
- Tax efficiency: Because the fund holds at least 65% in domestic listed equity (hedged), it generally qualifies as an equity-oriented fund. As per rules applicable from 23 July 2024, gains on units held up to 12 months are taxed at 20%, and longer-held gains at 12.5% on total equity long-term gains above ₹1.25 lakh a year. For investors in higher slabs, this can be lower than slab-rate taxation on debt funds.
- Market-linked opportunities: Spreads tend to widen when markets are volatile or optimistic and shrink when markets are calm, so returns are not fixed.

Benefits and Limitations
Benefits
- Low volatility compared with equity funds.
- Equity taxation, which may suit investors in higher tax brackets.
- Useful for parking money for a few months.
Limitations
- Returns depend on spreads, which can be thin in calm markets.
- Short-term returns can occasionally be negative, for example due to mark-to-market effects before expiry.

Comparison With Related Concepts
| Concept | Meaning | Key difference | Practical implication |
|---|---|---|---|
| Arbitrage fund | Hedged equity + short-term government debt | Equity-oriented taxation | Suits short-to-medium parking for higher-slab investors |
| Liquid fund | Debt and money market with maturity up to 91 days | Taxed at slab rate (units bought from 1 April 2023) | Faster access, very low volatility |
| Overnight fund | Securities maturing in 1 day | Lowest interest rate risk | For very short parking |
| Equity savings fund | 65%+ equity including arbitrage, net equity 15–40%, 10%+ debt | Has unhedged equity | Higher risk than arbitrage funds |
| Balanced advantage fund | Dynamic net equity | Larger unhedged equity | Much more market risk |
How Do Arbitrage Funds Apply to Mutual Fund Investors?
- Horizon: Commonly used for money needed in a few months to a year or so; check the exit load period before investing.
- Tax planning: Compare post-tax returns with liquid or money market funds based on your slab rate.
- Liquidity planning: Check the scheme's redemption timelines; for emergency money that may be needed immediately, liquid or overnight funds may be more suitable.
- STP source: Some investors park a lump sum in an arbitrage fund and use a Systematic Transfer Plan (STP) to move it gradually into equity funds.
- Performance review: Compare with arbitrage indices and peers, not with equity funds.
Common Mistakes and Misconceptions
- "Arbitrage funds are equity funds, so they are risky." Correct view: the equity is hedged, so market risk is low. Why it matters: investors may avoid a suitable parking option.
- "Returns are guaranteed." Correct view: returns depend on spreads and can vary or even be slightly negative over short periods. Why it matters: do not treat them like a fixed deposit.
- "They are a substitute for liquid funds in all situations." Correct view: exit loads and redemption timelines can make them less suitable for very short or emergency needs. Why it matters: liquidity needs should guide the choice.
- "They will grow wealth like equity over time." Correct view: long-term returns are generally modest and closer to short-term interest rates. Why it matters: they are not meant for long-term growth goals.
Important Terms to Know
- Hybrid Mutual Funds: Funds combining asset classes.
- Liquid Funds: Debt funds investing in instruments maturing up to 91 days.
- Exit Load: A charge for redeeming before a specified period.
- Systematic Transfer Plan (STP): Regular transfers from one scheme to another.
- Redemption Settlement Period: Time taken to receive redemption money.

- SEBI limits their debt to government securities under one year and government bond repos, and bars InvITs.
- They generally get equity-oriented taxation, which can help higher-slab investors.
- Returns are low-risk but not fixed, and exit loads are common.

Frequently Asked Questions
How do arbitrage funds make money?
They buy a stock in the cash market and sell the same quantity in the futures market at a higher price. At expiry the two prices converge, so the fund earns the difference regardless of whether the stock went up or down. Doing this across many stocks every month produces the fund's return, minus costs.
Are arbitrage funds safe?
They carry low market risk because their equity is hedged, and their debt is limited to short-term government securities and government bond repos. However, returns are not guaranteed and depend on available spreads. Short-term NAV movements can occasionally be negative. They are low-risk, not risk-free.
How are arbitrage funds taxed?
Arbitrage funds generally qualify as equity-oriented funds because they hold at least 65% in domestic listed equity. As per rules applicable from 23 July 2024, short-term gains (held up to 12 months) are taxed at 20%, and long-term gains at 12.5% on total equity long-term gains above ₹1.25 lakh a year.
Arbitrage fund or liquid fund: which is better for parking money?
It depends on your tax slab, horizon and liquidity needs. Liquid funds offer quicker access and no exit load after a few days, but gains on units bought from 1 April 2023 are taxed at slab rates. Arbitrage funds may give better post-tax results for higher-slab investors over a few months, but often carry exit loads.
Why do arbitrage fund returns change from month to month?
Returns depend on the gap between cash and futures prices, which reflects market demand, interest rates and volatility. When markets are buoyant or volatile, spreads tend to be wider; in calm or falling markets, spreads can shrink, reducing returns.
Is there an exit load on arbitrage funds?
Many arbitrage funds charge an exit load if units are redeemed within a short period, often a few weeks to a couple of months. The exact load and period vary by scheme, so check the scheme information document or factsheet before investing.
