Arbitrage funds are often misunderstood. On the surface, they look like equity funds. In reality, they behave more like low-risk, short-term investment options. Their goal is not to predict markets or pick winning stocks, but to quietly capture price differences that exist for very short periods.
Because of this unique structure, arbitrage funds are commonly used as a tax-efficient alternative to short-term debt funds, especially by investors in higher tax brackets.
This article explains arbitrage funds in detail—what they are, how they work, their key features, advantages, and the limitations you should clearly understand.

What Are Arbitrage Funds?
Arbitrage funds are mutual funds that aim to earn returns from price differences of the same stock in different markets, typically between the cash (spot) market and the futures market.
These funds buy a stock in the cash market and simultaneously sell it in the futures market when a price difference exists. When both positions are settled, the difference becomes the fund’s return.
By regulation, arbitrage funds maintain at least 65% exposure to equities, which gives them equity tax treatment, even though the risk profile is closer to debt funds.
How Arbitrage Funds Work?
Arbitrage opportunities arise due to temporary price mismatches.
A simplified example:
- A stock trades at ₹1,000 in the cash market
- The same stock trades at ₹1,010 in the futures market
- The fund buys in cash and sells in futures
- The ₹10 difference becomes locked-in profit
Because both buy and sell positions are taken simultaneously, market direction has little impact on returns.
Key Features of Arbitrage Funds
1. Low Market Risk
Returns do not depend on whether markets rise or fall.
2. Equity Taxation
Despite behaving like debt funds, arbitrage funds are taxed like equity funds.
3. Short-Term Investment Nature
Best suited for short holding periods.
4. High Liquidity
Investors can usually enter and exit easily.
5. Returns Depend on Market Conditions
Returns vary based on availability of arbitrage opportunities.
Advantages of Arbitrage Funds
1. Lower Risk Compared to Equity Funds
Because positions are hedged, volatility is limited.
2. Tax Efficiency
Long-term gains (after one year) are taxed at equity rates, which can be beneficial for high tax-bracket investors.
3. Useful Alternative to Debt Funds
Often used instead of liquid or short-term debt funds.
4. Stable Returns
NAV movement is usually smooth and steady.
5. Suitable for Parking Money Temporarily
Works well when money needs to stay invested for a few months.
Disadvantages of Arbitrage Funds
1. Limited Return Potential
Returns are usually modest and depend on market spreads.
2. Returns Fall in Low-Volatility Markets
When price differences shrink, returns reduce.
3. Not Completely Risk-Free
Operational and liquidity risks still exist.
4. Tax on Short-Term Gains
If redeemed before one year, gains are taxed at regular equity short-term rates.
5. Not Suitable for Long-Term Wealth Creation
Arbitrage funds are meant for stability, not growth.
Who Should Invest in Arbitrage Funds?
Arbitrage funds are suitable for investors who:
- Want low-risk, short-term investment
- Are in higher tax brackets
- Need an alternative to short-term debt funds
- Prefer stable returns
- Are parking money for a few months
They may not suit investors who:
- Want high returns
- Are investing for long-term goals
- Expect consistent income
Arbitrage Funds vs Other Funds
- Vs Liquid Funds: Better tax efficiency but similar return range.
- Vs Equity Funds: Much lower risk but limited upside.
- Vs Fixed Deposits: More flexible but no guaranteed return.
- Vs Ultra Short Duration Funds: Equity taxation advantage.
Understanding these differences helps investors use arbitrage funds properly.
Things to Check Before Investing
Before investing in an arbitrage fund, consider:
- Expense ratio
- Exit load
- Fund house execution efficiency
- Market conditions affecting spreads
- Your investment horizon
Avoid expecting equity-like returns.
Final Thoughts
Arbitrage funds are quiet performers. They don’t excite, and they don’t disappoint—if expectations are set correctly. Their strength lies in tax efficiency, stability, and low volatility.
For investors who want a safe place for short-term money with better tax treatment than debt funds, arbitrage funds can be a smart and practical choice.
