Imagine you have a year-end bonus that you want to park safely for a few months to a year during a volatile market. You want better returns than a savings bank account but without taking big equity risk. This is where arbitrage funds come into the picture. They aim to deliver low-volatility returns by exploiting price differences between the cash and derivatives markets. But are they truly safe? How do they work? And how do taxes affect your returns? This article explains arbitrage funds clearly, helping you decide if they suit your investment needs.
What Are Arbitrage Funds?
Simple definition
An arbitrage fund is a type of mutual fund that seeks to profit from the price difference between the cash (spot) market and the derivatives (futures) market. The fund typically buys the underlying stock in the cash market and simultaneously sells (shorts) the corresponding futures contract. This strategy aims to lock in a spread or premium, generating returns with relatively low volatility regardless of market direction.
Who typically manages these funds
These funds are managed by experienced fund managers who specialize in derivatives and equity markets. They use sophisticated models and risk controls to execute arbitrage trades efficiently, often across multiple stocks or indices.
How Arbitrage Funds Make Money — The Mechanics
Stock–futures arbitrage explained step-by-step
- The fund buys shares of a stock in the cash market at price X.
- Simultaneously, it sells a futures contract on the same stock at price Y, where Y is usually higher than X due to the futures premium.
- The fund holds these positions until just before the futures contract expires.
- Near expiry, the futures price converges with the cash price, allowing the fund to close both positions and pocket the spread (Y – X).
- Additional returns come from dividends on the underlying shares and interest earned on cash balances.
Example: numerical trade (buy cash + short futures)
Suppose the fund buys a stock at Rs 100 in the cash market and sells its futures contract at Rs 102. The gross spread is Rs 2 per share. After accounting for transaction costs (brokerage, taxes) of Rs 0.3 and margin costs of Rs 0.2, the net profit is Rs 1.5 per share. If the holding period is one month, this translates roughly to a 1.5% return before tax.
Other strategies managers may use
Besides equity arbitrage, some funds may employ index arbitrage (using index futures), convertible arbitrage, or special situation arbitrage. However, equity cash–futures arbitrage remains the core strategy for most Indian arbitrage funds.
Risk Profile: Why ‘Low Risk’ Is Not ‘No Risk’
Basis risk and scenario where hedges fail
Basis risk arises when the futures price does not converge perfectly with the cash price at expiry, causing the hedge to be imperfect and potentially leading to losses. For example, sudden market shocks or expiry mismatches can widen spreads unexpectedly.
Liquidity and margin risk
Arbitrage funds rely on margin trading for futures. In volatile markets, margin requirements can spike, forcing the fund to liquidate positions or raise cash quickly, which may hurt returns.
Manager/operational risk
Execution delays, slippage, or errors in trade timing can reduce profits. Additionally, operational risks such as settlement cycles (T+1, T+2) affect cash availability and carry.
Taxation & Regulatory Notes for Indian Investors (Including NRIs)
SEBI/AMFI classification (brief)
SEBI classifies mutual funds and mandates disclosure of equity exposure. Arbitrage funds typically maintain equity exposure around 65% or more to qualify as equity-oriented schemes, but this can vary.
Income tax treatment: equity vs debt classification and examples
If an arbitrage fund is classified as equity-oriented (equity exposure >=65%), gains held for more than one year are long-term capital gains (LTCG) taxed at 10% above Rs 1 lakh, and short-term capital gains (STCG) within one year are taxed at 15%. If classified as debt, LTCG applies after three years with indexation benefits, and STCG is taxed at the investor’s slab rate.
For example, if you invest Rs 1 lakh and redeem after 14 months with Rs 1.12 lakh NAV, the LTCG tax would be 10% on Rs 12,000 (above Rs 1 lakh exemption), i.e., Rs 1,200, leaving Rs 10,800 net gain.
NRI/FEMA/DTAA considerations (high-level)
NRIs must invest through PIS accounts and comply with FEMA regulations. Tax withholding rates depend on DTAA treaties between India and the investor’s country. Repatriation rules apply, and it is advisable to consult a tax advisor before investing.
Arbitrage Funds vs Alternatives: Which One Should You Pick?
| Feature | Arbitrage Funds | Liquid Funds | Short-Term Debt Funds | Bank FDs |
|---|---|---|---|---|
| Risk | Low to moderate (basis risk, margin risk) | Low | Low to moderate | Very low |
| Expected Returns | 4%–7% p.a. | 3%–5% p.a. | 4%–7% p.a. | 3%–6% p.a. |
| Tax Treatment | Equity or debt (depends) | Debt | Debt | Interest taxed as per slab |
| Liquidity | Usually T+1 redemption | Instant to T+1 | T+1 to T+3 | Premature withdrawal penalties |
| Minimum Tenure | Days to 18 months | Days | Months | Months to years |
| Best For | Parking cash with some yield uplift | Emergency funds | Short to medium term goals | Capital preservation |
Arbitrage funds can outperform liquid funds when futures premiums are stable and transaction costs are low. However, in stressed markets or when spreads compress, liquid funds or short-term debt funds may be safer.
How to Evaluate and Choose an Arbitrage Fund — A Practical Checklist
- Clear strategy documentation explaining arbitrage approach
- Experienced fund manager with derivatives expertise
- Reasonable Assets Under Management (AUM) to ensure liquidity
- Expense ratio low to moderate (typically 0.5%–1%)
- Consistent rolling returns over 1, 3, and 5 years
- Equity exposure history around 65% or more
- Portfolio turnover and transaction cost transparency
- Check for exit loads and minimum investment amounts
- Review latest Scheme Information Document (SID) and Key Information Memorandum (KIM)
- Avoid funds with very small AUM or inconsistent strategy
Real-World Examples & Scenario Analysis
Consider a fund that buys shares at Rs 100 and sells futures at Rs 102, with transaction costs of Rs 0.3 and margin costs Rs 0.2 per share. The net profit is Rs 1.5 per share or 1.5% monthly return before tax. Annualized, this is roughly 18% gross, but after fees, taxes, and market conditions, realistic returns are 6%–8% per annum.
Stress scenario 1: Futures premium collapses suddenly from Rs 2 to Rs 0.5 before expiry, reducing profit and possibly causing a small loss.
Stress scenario 2: Margin requirements spike during market volatility, forcing forced deleveraging and reducing returns.
How to Use Arbitrage Funds in Your Portfolio (Allocation Rules)
- Use arbitrage funds for horizons from a few days up to 18 months.
- Conservative investors can allocate 0%–10% of surplus cash as a ‘cash-plus’ option.
- Tactical investors may use up to 25% for short-term opportunities.
- SIPs are possible but lumpsum investments are more common for parking cash.
- Rebalance after market dislocations or when NAV volatility increases.
Common Mistakes to Avoid
- Ignoring post-tax returns and focusing only on gross returns.
- Assuming arbitrage funds are risk-free or equivalent to bank deposits.
- Choosing funds solely based on short-term past returns without checking strategy and AUM.
- Underestimating the impact of expense ratios and transaction costs.
- Using arbitrage funds as a long-term substitute for equity funds.
- Neglecting to verify tax classification and implications before investing.
Key Takeaways and Action Steps
Arbitrage funds offer a way to earn low-volatility returns slightly higher than cash alternatives by exploiting price differences between cash and futures markets. They are not risk-free and require careful evaluation of tax treatment, fund strategy, and market conditions. Use them for short to medium-term parking of surplus cash with a clear understanding of risks and costs.
- Check your investment horizon and tax status before investing.
- Compare expected post-tax returns with liquid funds and FDs.
- Use the checklist to select a fund with a clear strategy, experienced manager, and reasonable costs.

NRIs can invest but must comply with FEMA/PIS rules and consider DTAA tax treaties. Consult a tax advisor before investing.
Should I use SIP for arbitrage funds?
SIPs work but arbitrage funds are commonly used for lumpsum parking. For systematic savings, short-term debt funds may be simpler.
How do I pick the best arbitrage fund?
