What are Arbitrage Funds?
Meaning, Returns, Benefits and Risks — a simple guide to one of the most tax-efficient ways to park short-term money in India.
If you’ve ever wondered how to earn a little more than a savings account without taking on big equity risk, arbitrage funds are worth understanding. They’re a category of hybrid mutual funds that sound complex but work on a fairly simple idea — buy low in one market, sell high in another, at the same time.
What is an Arbitrage Fund?
An arbitrage fund is a type of hybrid mutual fund that profits from the price difference of the same stock between two markets — typically the cash (spot) market and the futures (derivatives) market. The fund manager simultaneously buys a stock in the cash market and sells an equal quantity in the futures market, locking in the price gap as a nearly risk-free profit, regardless of which direction the stock eventually moves.
Because this strategy involves taking offsetting positions, arbitrage funds are considered one of the safer categories within equity mutual funds — even though they’re technically classified as equity schemes for tax purposes.
How Do Arbitrage Funds Work?
Here’s a simplified example of the strategy in action:
Step 1 — Spot Purchase
The fund buys shares of a company in the cash market at the current price.
Step 2 — Futures Sale
Simultaneously, it sells the same quantity in the futures market at a (usually) higher price.
Step 3 — Settlement
On the futures expiry date, both positions are settled or rolled over, and the price difference becomes the fund’s return.
Since both positions are taken at the same time, the fund isn’t betting on the stock going up or down — it’s simply capturing the spread between two markets. This is what keeps the strategy relatively low-risk compared to a typical equity fund.
Arbitrage Fund Returns
Arbitrage fund returns depend on market volatility — the wider the price gap between cash and futures markets, the better the returns. Over the long term, arbitrage funds have historically delivered returns broadly comparable to short-duration debt funds or liquid funds, though returns can vary from year to year.
In periods of high market volatility, spreads widen and returns tend to be higher. In calmer, range-bound markets, spreads narrow and returns can dip closer to money-market levels. This is why arbitrage funds are best evaluated over a 6–12 month horizon rather than judged month to month.
Taxation of Arbitrage Funds
This is where arbitrage funds have a real edge. Even though the underlying strategy is low-risk, they are classified as equity-oriented funds for taxation (since they maintain a high allocation to equity and equity derivatives) — which means they enjoy equity-fund tax treatment rather than debt-fund tax treatment.
| Holding Period | Tax Treatment |
|---|---|
| Less than 12 months (STCG) | 20% tax on gains |
| More than 12 months (LTCG) | 12.5% tax on gains above ₹1.25 lakh in a financial year |
Compare this to a typical debt fund or fixed deposit, where interest income is taxed at your income slab rate — which can go up to 30%+ for higher earners. That gap is a major reason arbitrage funds are popular with HNIs and corporates parking surplus funds for the short term.
Benefits of Arbitrage Funds
- Low volatility: The buy-sell strategy hedges out market direction risk
- Tax-efficient: Equity taxation rates instead of slab-rate debt taxation
- Good for short-term parking: Suitable for money you may need in 3–12 months
- No lock-in: Most arbitrage funds are open-ended with easy redemption
- Diversification: A useful addition alongside pure equity or debt holdings
Risks of Arbitrage Funds
- Return variability: Returns shrink in low-volatility, range-bound markets
- Not guaranteed: Unlike a fixed deposit, returns are market-linked and not assured
- Expense ratio impact: Fund management costs can eat into already modest spreads
- Opportunity limitation: When arbitrage opportunities are scarce, fund managers may hold cash or debt instruments, which can further limit returns
- Exit load: Many arbitrage funds charge an exit load if redeemed within a short window (often 30–90 days)
Who Should Consider Arbitrage Funds?
Arbitrage funds tend to suit investors who:
- Want to park surplus or short-term money for 3 months to 2 years
- Are looking for a more tax-efficient alternative to short-term debt funds or FDs
- Prefer low volatility over high growth for a specific portion of their portfolio
- Already have a separate allocation to long-term equity funds for wealth creation
They are generally not meant to replace your core long-term equity investments — arbitrage funds play a supporting role, not a growth-driving one.
Frequently Asked Questions
Are arbitrage funds completely risk-free?
No. They are lower risk compared to pure equity funds because the strategy hedges directional market risk, but returns are still market-linked and not guaranteed.
Are arbitrage funds better than liquid funds?
It depends on your tax bracket and holding period. Because arbitrage funds get equity taxation, investors in higher tax slabs often find them more tax-efficient than liquid or short-duration debt funds for a similar risk level.
What is the ideal investment horizon for arbitrage funds?
Most advisors suggest a minimum horizon of 3–6 months, with better tax efficiency kicking in beyond 12 months due to LTCG treatment.
Can arbitrage funds give negative returns?
It’s rare but not impossible, especially over very short holding periods or during unusual market conditions. Over 3–6 month periods, negative returns have historically been uncommon.
