Arbitrage Funds in India: Meaning, Returns, Taxation, Benefits & Risks

When it comes to parking surplus money for the short term, investors often find themselves choosing between savings accounts, fixed deposits (FDs), liquid funds, and debt funds. However, there is another investment option that combines relatively low risk with tax efficiency—Arbitrage Funds.

In recent years, Arbitrage Funds have gained popularity among conservative investors seeking better post-tax returns than traditional fixed-income instruments. But what exactly are Arbitrage Funds, and how do they work?

In this comprehensive guide, we will explain everything you need to know about Arbitrage Funds, including their benefits, risks, taxation, and who should invest in them.

What Are Arbitrage Funds?

When investors have surplus money to deploy for a relatively short period, they often compare savings accounts, fixed deposits (FDs), liquid funds and other mutual funds.

Arbitrage Funds are another option. These mutual fund schemes seek to generate returns by taking advantage of price differences between the cash and derivatives markets, particularly the futures market.

Instead of primarily trying to predict whether the stock market will rise or fall, an arbitrage fund generally attempts to capture the spread between two related market positions.

The Securities and Exchange Board of India (SEBI) describes arbitrage mutual funds as schemes that seek to exploit price differences between the cash and derivatives markets. They fall within the equity-oriented mutual fund framework when the applicable classification conditions are satisfied.

For example, suppose a stock is trading at:

• Cash-market price: ₹1,500
• Three-month futures price: ₹1,530
• Price difference: ₹30

The fund can buy the stock in the cash market at ₹1,500 and simultaneously sell the corresponding futures position at ₹1,530.

If the positions converge as expected, the ₹30 represents the gross arbitrage spread before transaction costs, financing costs, taxes and fund expenses.

The actual return can therefore be lower than the initial price difference.

Arbitrage Fund Meaning: How Do They Work?

The objective of an arbitrage fund is generally not to make an outright bullish or bearish bet on the market.

Instead, the fund manager attempts to identify pricing differences and construct hedged positions.

A typical arbitrage transaction may involve:

1. Buying shares in the cash market.
2. Selling corresponding futures contracts.
3. Holding the positions until convergence or closing them earlier.
4. Capturing the available price spread after considering applicable costs.
5. Repeating the process across different securities and opportunities.

Because the cash and futures positions are generally offsetting, the strategy can significantly reduce directional equity-market exposure.

However, lower directional risk does not mean zero risk.

Arbitrage funds can still be affected by:

• Execution risk
• Liquidity risk
• Basis risk
• Settlement-related factors
• Transaction costs
• Changes in arbitrage spreads
• Regulatory changes
• Risks associated with the non-arbitrage portion of the portfolio

Therefore, arbitrage funds should not be treated as guaranteed-return investments.

How Arbitrage Funds Generate Returns

The primary source of return is the arbitrage spread between related cash and derivative positions.

Consider this simplified example:

• Cash price = ₹2,000
• Futures price = ₹2,040
• Spread = ₹40
• Holding period = 90 days

Gross return:

₹40 ÷ ₹2,000 × 100 = 2%

If the same 2% return were earned over 90 days, its simple annualised equivalent would be:

2% × 365 ÷ 90 = approximately 8.11%

However, this is only a mathematical annualisation of one hypothetical trade. It is not a forecast or guaranteed annual return.

Actual fund returns can be affected by:

• Brokerage and transaction expenses
• Securities Transaction Tax (STT)
• Bid-ask spreads
• Fund expenses
• Slippage
• Financing and cash-management costs
• Availability of arbitrage opportunities
• Changes in futures premiums

When arbitrage spreads narrow, the potential return from new trades can also decline.

Cash Market vs Futures Market: Understanding Arbitrage Opportunities

The cash market is where investors buy or sell the underlying security.

The futures market involves derivative contracts whose value is linked to the underlying security and which operate according to exchange and regulatory rules.

Consider this simplified example:

The fund buys the stock for ₹1,000 and sells the futures contract for ₹1,025.

Suppose the positions later converge around ₹1,010:

• Cash position gain = ₹10
• Futures position loss = ₹15
• Combined result = approximately ₹25

This ₹25 represents the gross spread in this simplified example, before applicable costs and other adjustments.

Actual transactions can differ depending on settlement mechanics, dividends, contract specifications, timing and trading costs.

Key Features of Arbitrage Funds

Equity-Oriented Tax Treatment

Qualifying arbitrage funds are generally treated as equity-oriented mutual funds for tax purposes, subject to the applicable statutory and scheme-level conditions. The tax classification can depend on maintaining the required equity exposure over the relevant period.

Hedged Investment Strategy

The strategy generally combines cash-market purchases with corresponding derivative positions to reduce directional market exposure.

Market-Linked Returns

Unlike a fixed deposit, arbitrage fund returns are not predetermined or guaranteed.

Open-Ended Structure

Most arbitrage funds are open-ended schemes, allowing purchases and redemptions according to the scheme's applicable terms.

Relatively Lower Volatility

Because the strategy is generally hedged, arbitrage funds can experience lower volatility than conventional equity funds. However, they can still experience NAV fluctuations and losses.

Benefits of Investing in Arbitrage Funds

1. Lower Directional Equity Exposure

The hedged strategy reduces the impact of broad market movements compared with an unhedged equity investment.

2. Potential Tax Efficiency

For some investors, equity-oriented capital-gains taxation may result in a more favourable post-tax outcome than interest income taxed at the investor's applicable slab rate.

3. Professional Management

Fund managers monitor cash prices, futures prices, spreads, liquidity and market conditions.

4. Diversification Across Opportunities

A fund can execute arbitrage strategies across multiple securities rather than relying on a single transaction.

5. Useful for Certain Short-to-Medium-Term Allocations

Arbitrage funds may be considered when investors want to temporarily deploy surplus money while accepting market-linked returns.

However, they should not automatically be considered equivalent to a savings account, liquid cash reserve or guaranteed-return product.

Arbitrage Fund Returns: What Can Investors Expect?

There is no fixed or guaranteed return from an arbitrage fund.

Returns depend on the availability and attractiveness of arbitrage opportunities.

When futures trade at a meaningful premium to the underlying security, the potential spread may be attractive. When spreads narrow because of market conditions, liquidity, competition or other factors, the return opportunity can reduce.

Investors should therefore evaluate:

• Rolling returns
• Consistency of performance
• Expense ratio
• Portfolio turnover
• Exit load
• Portfolio composition
• Liquidity
• Performance across different market conditions

A single year's return should not be treated as an expected future return.

Past performance is not a guarantee of future results.

Arbitrage Fund Taxation in India (2026)

One of the key features of qualifying arbitrage funds is their equity-oriented tax treatment.

For qualifying transactions subject to the applicable conditions, including STT requirements:

• Short-Term Capital Gains (STCG): 20%
• Long-Term Capital Gains (LTCG): 12.5% on eligible gains exceeding ₹1.25 lakh in a financial year

The Income Tax Department currently specifies the 20% Section 111A rate for qualifying short-term gains from equity shares and units of equity-oriented mutual funds transferred on or after 23 July 2024. For Section 112A, eligible long-term gains above ₹1.25 lakh are taxed at 12.5% for transfers on or after that date.

The applicable rules should always be checked for the relevant financial year and transaction.

Short-Term vs Long-Term Capital Gains Tax

For qualifying equity-oriented mutual fund units:

The Section 112A ₹1.25 lakh threshold is an aggregate annual threshold for eligible long-term gains, rather than a separate ₹1.25 lakh exemption for each mutual fund scheme.

STCG Calculation Example

Suppose:

• Investment = ₹5,00,000
• Redemption value = ₹5,35,000
• Capital gain = ₹35,000
• Holding period = 8 months

Because the units were held for 12 months or less, the gain is treated as STCG, assuming the applicable Section 111A conditions are satisfied.

Tax before cess:

₹35,000 × 20% = ₹7,000

Health and Education Cess at 4%:

₹7,000 × 4% = ₹280

Illustrative tax:

₹7,280

Illustrative post-tax gain:

₹35,000 − ₹7,280 = ₹27,720

This calculation excludes any applicable surcharge and assumes the entire gain is taxable at the stated rate.

LTCG Calculation Example

Suppose an investor has eligible long-term capital gains of:

₹2,00,000

Assuming the investor has not already used the annual ₹1.25 lakh Section 112A threshold:

Taxable LTCG:

₹2,00,000 − ₹1,25,000 = ₹75,000

Tax:

₹75,000 × 12.5% = ₹9,375

Health and Education Cess at 4%:

₹9,375 × 4% = ₹375

Illustrative total:

₹9,750

The actual tax liability can differ based on the investor's total eligible gains, surcharge, cess and other applicable provisions.

The Income Tax Department confirms that the ₹1.25 lakh threshold applies to eligible aggregate long-term gains under Section 112A.

Dividend Taxation and Other Tax Considerations

Income distributed by mutual funds is generally taxable in the hands of the investor according to the applicable tax rules.

Therefore, investors should evaluate the total post-tax outcome rather than focusing only on any distribution.

No Special Section 80C Deduction

Investing in an ordinary arbitrage fund does not itself provide a Section 80C deduction.

The overall Section 80C deduction limit is ₹1.5 lakh, but the deduction applies only to specified eligible investments and expenses.

Therefore, an investor cannot claim a ₹1.5 lakh deduction simply by investing ₹1.5 lakh in an arbitrage fund.

Similarly, arbitrage-fund capital gains should not be confused with savings-account interest eligible for Section 80TTA.

The tax benefit of arbitrage funds primarily comes from their equity-oriented capital-gains taxation, not from an upfront Section 80C deduction. The Income Tax Department also specifies that Chapter VI-A deductions are not available against concessional Section 112A gains.

Tax rules can change, so investors should verify the applicable provisions before making investment decisions.

Risks Associated With Arbitrage Funds

Arbitrage funds are relatively lower-risk than many conventional equity funds, but they are not risk-free.

1. Arbitrage Spread Risk

The expected price difference can narrow before the transaction is completed.

2. Liquidity Risk

A security or derivative contract may not always be available at the expected price or volume.

3. Execution Risk

Differences between quoted and executed prices can reduce the expected spread.

4. Basis Risk

Cash and futures prices may not move in perfect synchronisation at every point in time.

5. Debt-Market Risk

The non-arbitrage portion may be invested in debt or money-market instruments and can carry associated credit, liquidity or interest-rate risks.

6. Regulatory Risk

Changes in derivatives regulations, taxation, exchange rules or transaction costs can affect arbitrage strategies.

7. Return Risk

When attractive arbitrage opportunities are limited, fund returns may decline.

Costs, Expense Ratio & Exit Load

Investors should review the scheme's:

• Expense ratio
• Exit-load structure
• Portfolio turnover
• Transaction costs
• Portfolio composition
• Scheme-level expenses

Costs matter because arbitrage spreads can be relatively modest.

For example, suppose two funds each generate a hypothetical gross return of 7% on ₹5 lakh.

Fund A's effective annual cost = 0.50%

Fund B's effective annual cost = 0.80%

Approximate annual cost difference:

₹5,00,000 × 0.30% = ₹1,500

This is a simplified illustration. Mutual-fund expenses are generally reflected in the NAV rather than being separately billed to the investor.

Arbitrage Funds vs Liquid Funds

Both products can be considered for relatively short-term money, but their strategies differ.

Which Is Better?

An arbitrage fund may appeal to an investor who wants a relatively low-volatility market-linked strategy and potentially favourable equity-oriented taxation.

A liquid fund may be more suitable when the primary objective is short-term cash management and liquidity.

The decision should be based on the investment horizon, taxation, costs, liquidity requirements and risk tolerance.

Arbitrage Funds vs Fixed Deposits

Fixed deposits and arbitrage funds have fundamentally different return structures.

Post-Tax Illustration

Suppose ₹5 lakh generates a hypothetical 7% return:

₹5,00,000 × 7% = ₹35,000

If an FD investor is assumed to be in a 30% marginal tax bracket, ignoring cess and surcharge:

₹35,000 × 30% = ₹10,500

Approximate post-tax interest:

₹35,000 − ₹10,500 = ₹24,500

For an arbitrage fund, taxation depends on the nature and holding period of the capital gain.

Therefore, an arbitrage fund may produce a different post-tax outcome, but it does not guarantee a higher return than an FD.

Arbitrage Funds vs Equity Savings Funds

Arbitrage funds and equity savings funds can both use equity, derivatives and debt-related instruments, but their objectives differ.

An equity savings fund can have a meaningful unhedged equity component, allowing greater participation in equity-market gains but also greater exposure to market declines.

An arbitrage fund generally focuses more heavily on hedged opportunities and therefore may be more appropriate for investors prioritising lower volatility.

Quick Comparison: Four Investment Options

Fixed deposits do not have mutual-fund NAV volatility, but bank/deposit-provider risk and applicable deposit-insurance limits still need to be considered.

Who Should Invest in Arbitrage Funds?

Arbitrage funds may be considered by:

• Investors seeking relatively lower volatility
• Investors with short-to-medium-term investment objectives
• Investors comparing post-tax returns with taxable fixed-income alternatives
• Investors temporarily holding surplus money
• Investors comfortable with market-linked returns
• Investors who understand that returns are not guaranteed

For comparing post-tax investment outcomes, investors can use a post-tax return calculator.

Who Should Avoid Arbitrage Funds?

Arbitrage funds may not be appropriate for investors who:

• Require guaranteed returns
• Need immediate access to all their money
• Have an extremely short investment horizon
• Seek aggressive long-term capital appreciation
• Cannot tolerate NAV fluctuations
• Have not reviewed exit-load and taxation rules

For long-term wealth creation, diversified equity investments may offer greater growth potential, although they also carry substantially higher market risk.

How to Invest in Arbitrage Funds

Investors can generally invest through:

1. Direct mutual-fund platforms
2. AMC platforms
3. Registered investment platforms
4. Mutual-fund distributors
5. Other registered intermediaries

Before investing:

1. Complete KYC requirements.
2. Understand the scheme's investment objective.
3. Compare direct and regular plans.
4. Check the scheme's riskometer.
5. Review the Scheme Information Document.
6. Compare expense ratios.
7. Check exit-load provisions.
8. Review the portfolio and investment strategy.
9. Understand the applicable taxation.
10. Match the investment with your financial goal and horizon.

Factors to Consider Before Investing

Check the Investment Strategy

Understand how the fund identifies and executes arbitrage opportunities and how it manages periods when opportunities are limited.

Compare Expense Ratios

When gross arbitrage spreads are moderate, expenses can have a meaningful effect on net returns.

Examine Exit Load

An exit load can reduce the proceeds from an early redemption.

Evaluate Rolling Returns

Rolling returns can provide a more useful picture of consistency than a single calendar-year return.

Review Portfolio Quality

Check the debt and money-market component, credit quality and liquidity.

Consider Post-Tax Returns

Always compare investments on a post-tax basis.

For example, a hypothetical 7% return on ₹5 lakh produces:

₹5,00,000 × 7% = ₹35,000 gross gain

The amount retained after tax depends on the holding period, applicable capital-gains rules and the investor's overall tax position.

Example: How an Arbitrage Trade Works

Consider this simplified transaction:

Stock: XYZ Ltd.
Cash price: ₹1,000
Three-month futures price: ₹1,025
Spread: ₹25

The fund:

• Buys XYZ shares at ₹1,000
• Sells XYZ futures at ₹1,025

Gross arbitrage return:

₹25 ÷ ₹1,000 × 100 = 2.5%

If the transaction lasts 90 days, the simple annualised equivalent is:

2.5% × 365 ÷ 90 = approximately 10.14%

This does not mean the fund will earn 10.14% annually.

It simply annualises one hypothetical 90-day spread.

Actual returns would depend on the ability to execute the transaction, costs, taxes, fund expenses and the availability of subsequent arbitrage opportunities.

This is why investors should evaluate the net realised spread and overall fund performance, rather than simply looking at the cash-futures price difference.

Final Verdict: Are Arbitrage Funds a Good Investment in 2026?

Arbitrage funds occupy a distinctive position in India's mutual-fund market.

Their primary objective is to capture pricing differences between related cash and derivative positions rather than make a straightforward bullish or bearish equity-market call.

Their hedged strategy can result in relatively lower volatility than conventional equity funds, while their qualifying equity-oriented tax treatment can make them attractive for certain investors.

However, they are not guaranteed-return products.

Returns depend on:

• Availability of arbitrage opportunities
• Size of spreads
• Execution conditions
• Liquidity
• Transaction costs
• Fund expenses
• Market and regulatory conditions

For investors considering an arbitrage fund in 2026, the key questions are:

• What is the investment horizon?
• What alternative investment is being considered?
• What is the expected post-tax return?
• What are the costs and exit load?
• Is the investor comfortable with market-linked NAV movements?
• Does the investment fit the overall asset-allocation strategy?

Ultimately, an arbitrage fund should be evaluated based on investment objective, liquidity requirements, taxation, risk tolerance, costs and investment horizon, rather than the expectation of a fixed return.
