Imagine you are a salaried professional with a sizeable year-end bonus and want to park this money safely for 6 to 12 months. Bank fixed deposits (FDs) offer safety but limited post-tax returns, especially in volatile markets. This is where arbitrage funds come into play — they aim to provide low-volatility returns by exploiting price differences between cash and futures markets, offering a market-neutral alternative to traditional debt instruments.
What Are Arbitrage Funds? (Arbitrage Funds Explained)
Cash-futures arbitrage explained simply
Arbitrage funds are mutual funds that primarily engage in cash-futures arbitrage. This means they simultaneously buy stocks in the cash market and sell equivalent futures contracts on those stocks or indices. The goal is to capture the price difference (spread) between the cash price and the futures price, which tends to be small but relatively stable. Because the fund holds both long and short positions, it remains market-neutral, meaning it is less affected by overall market movements.
Other arbitrage strategies — why mutual funds focus on cash-futures
While arbitrage can also occur in merger arbitrage or convertible arbitrage, mutual funds in India predominantly use cash-futures arbitrage due to regulatory clarity, liquidity, and ease of execution. This strategy is well-suited for mutual funds aiming to deliver low-risk returns.
How Arbitrage Funds Generate Returns — The Cash-Futures Trade
Step-by-step trade lifecycle
- The fund buys shares in the cash market.
- Simultaneously, it sells futures contracts on the same shares or index.
- The difference between the futures price and the cash price (the spread) is captured as profit when the positions are squared off.
Why spreads exist
Spreads arise due to factors like interest rate differentials, dividends, and market microstructure inefficiencies. For example, futures prices typically include the cost of carry (interest cost minus dividends), creating a predictable spread over the cash price.
When arbitrage opportunities shrink or disappear
In calm markets or when futures and cash prices converge closely, arbitrage spreads narrow, reducing potential returns. Conversely, during volatile periods, spreads may widen but execution risks increase.
Typical Returns, Fees and Risk Profile
Historic return band and volatility
Arbitrage funds in India have historically delivered annualised returns in the range of 6% to 9%, with volatility significantly lower than equity funds but slightly higher than liquid funds. Returns depend on market conditions and the fund manager’s ability to execute trades efficiently.
Expense ratio and turnover impact
Expense ratios typically range from 0.5% to 1.2%. High portfolio turnover due to frequent arbitrage trades can increase costs, impacting net returns. Exit loads may apply for short holding periods, so investors should check fund documents.
Key risks with examples
- Basis risk: The risk that futures and cash prices do not move perfectly in tandem, causing losses.
- Execution risk: Delays or failures in trade execution, especially during expiry weeks, can reduce returns.
- Expiry liquidity risk: Reduced liquidity near futures expiry can widen spreads unexpectedly.
- Counterparty/settlement risk: Though minimal in regulated exchanges, operational failures can occur.
- Interest rate risk: Changes in interest rates affect the cost of carry and spreads.
Taxation: How Arbitrage Funds Are Taxed in India
65% equity exposure rule and classification
Tax treatment depends on the fund’s equity exposure. If the fund maintains at least 65% allocation to equities, it is classified as an equity fund for tax purposes; otherwise, it is treated as a debt fund.
STCG and LTCG rules for equity funds
For equity-classified arbitrage funds, short-term capital gains (STCG) on holdings under 12 months are taxed at 15%. Long-term capital gains (LTCG) over ₹1 lakh are taxed at 10% without indexation benefits.
Tax treatment if classified as debt
If classified as debt, STCG is taxed as per the investor’s income tax slab, and LTCG (holding period over 36 months) is taxed at 20% with indexation benefits.
Dividends and TDS
Since Budget 2020, dividends are taxable in the hands of investors at their applicable slab rates. For NRIs, TDS applies on dividends and capital gains, with rates subject to Double Taxation Avoidance Agreements (DTAA).
NRIs: TDS, FEMA and DTAA considerations
NRIs can invest through NRE or NRO accounts following FEMA regulations. TDS applies on gains and dividends, but DTAA provisions may reduce withholding rates. Proper documentation and tax advice are recommended.
Arbitrage Funds vs Other Low-Risk Options
Comparing arbitrage funds with liquid funds, ultra-short funds, and fixed deposits helps clarify their place in a portfolio.
| Feature | Arbitrage Funds | Liquid Funds | Fixed Deposits |
|---|---|---|---|
| Typical Pre-Tax Returns | 6% – 9% | 4.5% – 6.5% | 5% – 7% |
| Volatility | Low to Moderate | Very Low | Very Low |
| Tax Treatment | Equity or Debt (65% rule) | Debt | Taxed as Interest Income |
| Liquidity | Generally 1-2 days | Same day or next day | Premature withdrawal penalties |
| Expense Ratio | 0.5% – 1.2% | 0.2% – 0.5% | None |
After-tax returns depend heavily on your tax bracket and holding period. For example, a 30% tax bracket investor holding an equity-classified arbitrage fund for over a year benefits from 10% LTCG tax, often outperforming liquid funds taxed at slab rates.
Who Should Invest in Arbitrage Funds?
Arbitrage funds suit investors seeking low-volatility returns with some equity exposure benefits, such as:
- Salaried professionals parking bonuses for 3 to 12 months.
- HNIs looking for tax-efficient short-term parking.
- NRIs wanting to invest in Indian markets with moderate risk.
- Investors aiming to reduce portfolio volatility while maintaining some equity linkage.
How to Select the Right Arbitrage Fund — A Step-by-Step Checklist
- Check equity exposure percentage (≥65% for equity classification).
- Review derivatives exposure and trade frequency in the fund fact sheet.
- Assess expense ratio and portfolio turnover.
- Look for stable and sizeable Assets Under Management (AUM).
- Evaluate historical returns consistency and volatility.
- Confirm presence of an experienced arbitrage desk or fund manager.
- Check exit load and minimum holding period.
- Review benchmark and alpha generation.
- Verify transparency in disclosures, especially derivatives positions.
Practical Implementation: SIP, Lumpsum, Exit Strategy and NRIs
SIP is allowed in arbitrage funds but may not offer the same rupee cost averaging benefits as equity or debt funds because returns depend on arbitrage opportunities that fluctuate. Lumpsum investments are common for short-term parking.
Avoid exiting during futures expiry weeks to reduce execution risk. For NRIs, investing through NRE accounts is preferable for repatriability. Ensure compliance with FEMA and consult tax advisors for TDS and DTAA benefits.
Common Mistakes to Avoid
- Assuming arbitrage funds are risk-free and parking large sums without understanding risks.
- Ignoring expense ratios and turnover impact on net returns.
- Overlooking tax implications when comparing with liquid funds or FDs.
- Choosing funds based solely on recent returns without checking strategy adherence.
- Not verifying true equity and derivatives exposure in fund documents.
Case Studies & Worked Examples
Consider an investor in the 30% tax bracket who invests ₹10 lakh in an equity-classified arbitrage fund for one year. Assuming a 7.5% pre-tax return, the after-tax return would be approximately 6.3% after 10% LTCG tax on gains above ₹1 lakh. In contrast, a liquid fund taxed at slab rates might yield a lower after-tax return.
During a volatile expiry week, arbitrage spreads may widen, but execution risks increase. Some funds may experience slippage, reducing returns temporarily. Understanding these dynamics helps set realistic expectations.
Quick Takeaways and Final Recommendation
- Arbitrage funds offer a market-neutral, low-volatility investment option suitable for short to medium-term parking.
- They are not risk-free; understanding basis, execution, and liquidity risks is essential.
- Tax classification (equity vs debt) significantly impacts after-tax returns.
- Compare arbitrage funds with liquid funds and FDs based on your tax bracket and investment horizon.
- Use a detailed checklist to select funds with transparent strategies and reasonable costs.

FAQs
What are arbitrage funds and how do they make money?
Arbitrage funds buy the underlying stock and short the futures contract to capture the price difference between the two. Returns come mainly from capturing the spread, not from market direction.
Are arbitrage funds risk-free?
No. They are relatively low-risk compared with equity funds but have risks such as basis risk, execution risk, liquidity issues at expiry, and operational risk. They can lose money in stressed conditions.
How are arbitrage funds taxed in India?
Tax classification depends on the fund’s equity exposure. If the scheme maintains ≥65% allocation to equities, it’s taxed as an equity fund (STCG 15%, LTCG 10% over ₹1 lakh). If less, it’s treated as debt (STCG taxed as per slab, LTCG taxed at 20% with indexation).
Do arbitrage funds beat liquid funds after tax?
It depends on your tax bracket and holding period. For investors in higher tax brackets and for holding periods over one year, arbitrage funds classified as equity may be more tax-efficient.
Can NRIs invest in arbitrage funds and what about TDS?
Yes, NRIs can invest through NRE/NRO accounts subject to FEMA. TDS applies on capital gains and dividends; DTAA may reduce TDS. Consult a tax advisor and provide necessary forms to claim treaty benefits.
Is SIP suitable for arbitrage funds?
SIP is allowed but may offer limited benefits compared to debt or equity funds due to the nature of arbitrage returns. Lumpsum investments are common for short-term parking.
How do I pick the best arbitrage fund?
Use a checklist: stable AUM, low expense ratio, transparent derivatives disclosure, low exit load, consistent returns, and experienced arbitrage desk. Review fund fact sheets carefully.
