Want better-than-FD returns without equity volatility? Arbitrage funds might be your answer.

In the world of mutual funds, risk and return often go hand-in-hand.

But arbitrage funds offer a unique proposition—they aim to give you returns similar to short-term debt, but are taxed like equity.

This makes them especially attractive for short-term investors, those parking surplus funds for a few months, or even conservative investors seeking efficient alternatives to liquid or ultra-short-term funds.

Let’s understand what arbitrage funds are, how they work, and when you should consider using them.


1. What Are Arbitrage Funds?

Arbitrage funds are hybrid mutual funds that:

  • Simultaneously buy stocks in the cash market and sell in the futures market of the same stock

  • Earn the price difference (spread) between the two markets

  • Typically maintain 65%+ in hedged equity positions to qualify for equity taxation

  • The rest is invested in debt or money market instruments for additional income

Since each equity position is offset by a corresponding futures position, the net equity market risk is near zero.

2. How Do Arbitrage Funds Generate Returns?

The price of a stock in the futures market is often slightly higher than in the spot (cash) market. This difference is called the arbitrage spread.

Fund managers exploit this spread:

  • Buy the stock in the cash market

  • Simultaneously sell it in the futures market

  • Pocket the spread at settlement

Returns depend on: ✅ The size of the arbitrage spread

✅ Interest rate trends

✅ Market liquidity and volatility

Historically, arbitrage funds have generated returns in the 5–7% range, with minimal volatility.


3. Key Benefits of Arbitrage Funds

Low Volatility

They’re among the least volatile equity funds, often behaving like ultra-short debt funds.

Tax Efficiency

Despite low risk, they are taxed as equity funds:

  • STCG (<1 year): 20%

  • LTCG (>1 year): 12.5% (after ₹1 lakh exemption)

Good for Short-Term Parking

Ideal for 3–12 month horizons when you want better returns than liquid funds or FDs—without taking equity risk.

Can Be Used for SWP

Especially effective for retirees seeking low-risk, tax-friendly monthly income.

5. When Should You Use Arbitrage Funds?

✅ You need a parking space for idle funds (bonus, sale proceeds, etc.) for 3–12 months

✅ You want to avoid equity volatility, but enjoy equity tax benefits

✅ You’re a retiree looking for SWP-friendly, low-volatility funds

✅ You’re investing in a volatile market and want safety until better clarity emerges

✅ You’re building a step-up STP strategy (move from arbitrage to equity via Systematic Transfer Plans)


6. Key Considerations Before Investing

⚠️ Returns are not fixed or guaranteed

They depend on arbitrage spreads, which may narrow in calm markets

⚠️ Not suitable for long-term growth

They don’t generate inflation-beating returns like equity or hybrid funds

⚠️ Not a replacement for liquid funds in emergency corpus

Since they’re T+2 (two-day settlement), liquidity is slightly delayed


7. How Long Should You Stay Invested?

⏳ Minimum recommended horizon: 3–6 months

⏳ For tax efficiency: 12+ months (to enjoy 12.5% LTCG with ₹1 lakh exemption)

Arbitrage funds reward patient short-term investing, not overnight trades.

TL;DR — Too Long; Didn’t Read

  • Arbitrage funds earn from the price difference between cash and futures markets—not from equity rallies

  • Offer low-risk, tax-efficient returns (5–7%), best suited for 3–12 month holding periods

  • Ideal for short-term parking, SWPs, and conservative investors seeking better-than-FD options

  • Taxed like equity: 20% (STCG) or 12.5% LTCG after 1 year

  • Not meant for long-term wealth creation, but great for low-risk, tactical allocations
