Arbitrage Funds: The Tax-Efficient Safe Haven
Last updated: 12 October 2026
Quick answer: An arbitrage fund is a hybrid mutual fund that buys shares in the cash market and sells the same quantity in futures, earning the price gap. Because it holds at least 65% in hedged equity, gains get equity taxation: 20% within 12 months and 12.5% above ₹1.25 lakh after that, versus slab-rate tax on FDs.
Last updated: 12 October 2026 Quick answer: An arbitrage fund is a hybrid mutual fund that buys shares in the cash market and sells the same quantity in futures, earning the price gap. Because it holds at least 65% in hedged equity, gains get equity taxation: 20% within 12 months and 12.5% above ₹1.25 lakh after that, versus slab-rate tax on FDs. Key takeaways Market-neutral return engine: profit comes from the cash-futures spread, which is locked in when both legs are placed. Equity taxation: 20% STCG within 12 months; 12.5% LTCG above ₹1.25 lakh a year, unlike FDs and debt funds taxed at slab rate. Returns: about 6.6-7.1% a year over FY 2023-26 for large category funds, with wider month-to-month swings (not a forecast). 2026 rule change: SEBI's 26 February 2026 circular limits the debt portion to government securities under one year and G-sec repos. Best for: surplus money parked for 3 months to a year or more, especially by investors in the 20-30% tax brackets. In the volatile world of equity markets, investors often seek a safe harbour that offers better returns than a savings account but without the roller-coaster ride of stocks. Enter Arbitrage Funds — a category of hybrid mutual funds long popular with HNI and corporate treasury investors in India, and increasingly a retail favourite, for one reason: they combine equity-fund taxation with debt-fund-like stability. What is an Arbitrage Fund? An Arbitrage Fund profits from the price gap between the Cash Market (buying shares) and the Derivatives Market (selling futures) on the same stock — not from the stock price rising. The manager simultaneously buys in cash and sells an equal quantity in futures. Both legs execute together, so the profit — the "spread" — is locked in on day one, regardless of which way the stock later moves. How an arbitrage fund locks in returns: buy a share at ₹2,500 in the cash market, sell futures at ₹2,510, lock in a ₹10 spread; arbitrage fund category returned about 6.6-7.1% over three years The arbitrage trade in four numbers Simple example: Reliance trades at ₹2,500 in cash and ₹2,510 in futures (month-end expiry). The manager buys cash at ₹2,500 and sells futures at ₹2,510 — locking ₹10/share. On expiry, cash and futures converge, and that ₹10 is secured whether Reliance has since moved to ₹3,000 or ₹2,000. Multiply across hundreds of such pairs, repeated monthly as contracts roll over — that's the return engine. Where the Return Actually Comes From Spread size is driven mainly by prevailing interest rates and market volatility — rising volatility tends to widen spreads and lift returns; calmer markets compress spreads toward the lower end of the range. This is why arbitrage returns aren't a fixed number and fluctuate month to month, even though the strategy carries very low market risk. What Arbitrage Funds Have Actually Returned Based on trailing 3-year performance (FY 2023–26) of five large category funds, annualised returns have ranged roughly 6.6% to 7.1% , with monthly variability — from around 3% annualised in calm stretches to 8–9% annualised in higher-volatility periods. They smooth to a moderate, FD-like return over a full year, but monthly numbers swing more than expected, so judge on rolling 6–12 month performance, not a single month. Illustrative historical ranges based on category data at time of writing, not a forecast — past performance doesn't guarantee future returns; verify against a fund's current factsheet. The Full Tax Picture Because arbitrage funds maintain equity exposure above the regulatory threshold (typically over 65%, via combined cash and futures positions), they qualify for equity-fund taxation — significantly more favourable than an FD or debt fund. Arbitrage Fund Fixed Deposit Debt Mutual Fund Tax treatment Equity taxation (Sec 112A) Interest taxed at slab rate yearly Gains taxed at slab rate (all holding periods, investments after 1 Apr 2023) Short-term rate 20% (holding ≤12 months) Slab rate Slab rate Long-term rate 12.5% (holding >12 months) Not applicable Not applicable Annual exemption ₹1.25 lakh/year on LTCG None None Tax triggered Only on redemption Every year, even if not withdrawn Only on redemption, at full slab rate Rates reflect the capital gains structure effective 23 July 2024 (Sec 112A) and debt-fund rules effective 1 April 2023, current at time of writing. Tax rules can change in future Finance Acts — confirm current provisions with your tax advisor. Why This Matters in Practice For a 30% bracket investor, the gap compounds yearly. An FD paying roughly 6%–7.5% (typical range across major Indian banks in 2026) has its entire interest taxed as income annually — post-tax return can fall to roughly 4.2%–5.3%. An arbitrage fund returning a similar 6.5%–7% pre-tax, held over a year, is taxed at just 12.5% beyond the ₹1.25 lakh exemption — post-tax return stays much closer to the pre-tax number. Similar pre-tax return, meaningfully better post-tax return, for a high-tax-bracket investor. Arbitrage Fund vs FD vs Debt Fund vs Liquid Fund Arbitrage Fund Fixed Deposit Debt Fund Liquid Fund Use case Surplus cash, 3 months–1 year+ Fixed-term savings Medium-term debt allocation Very short-term (days–weeks) Capital safety High (market-neutral), not guaranteed Guaranteed up to ₹5 lakh (DICGC) Credit/rate risk High, very short duration Liquidity High, redeem in 1–2 days (exit load if early) Low — penalty on premature withdrawal High Very high Tax efficiency High (equity taxation) Low (taxed yearly as income) Low Low Ideal holding 3 months–1 year+ (12mo+ for LTCG) Matches tenure 1 year+ Days–few months What Changed for Arbitrage Funds in 2026 SEBI's revised mutual fund categorisation circular of 26 February 2026 kept the core rule for arbitrage funds unchanged: at least 65% of assets must be in equity and equity-related instruments, which is what keeps them eligible for equity taxation. What changed is the non-arbitrage portion. Arbitrage funds can no longer invest in InvITs, and their debt holdings are now limited to government securities with less than one year to maturity and repos on government bonds. In practice this makes the cash portion of an arbitrage fund lower in credit risk than before, so the main things left to compare between schemes are expense ratio, exit load, size and rolling returns. Tax treatment for FY 2026-27 is unchanged: 20% on gains within 12 months and 12.5% on long-term gains above ₹1.25 lakh a year. Who Should Invest in Arbitrage Funds? Best suited for investors in the 20%–30%+ tax brackets parking surplus money for 3 months to a year or more — a bonus, a property-sale proceed awaiting reinvestment, an emergency fund's "second layer," or corporate treasury surplus. A poor fit as a substitute for long-term equity investing (return profile is closer to debt despite equity tax treatment) or for money needed within days, where a liquid fund fits better. Risks to Understand Before Investing Low-risk, not zero-risk: spread compression in calm markets can pull returns lower for a period; not capital-guaranteed — no FD-like government guarantee; expense ratio drag — modest gross spreads mean costs matter more; exit load on early redemption (commonly ~30 days); rare deployment risk — a very large fund can find it harder to deploy all assets into profitable spreads. How to Choose an Arbitrage Fund Compare 3-year rolling returns, not the best single month. Prefer lower expense ratios — they matter more here than in equity funds. Consider fund size (AUM) — a well-established, mid-to-large fund with a stable track record is usually safer. Check the exit load window. Commit 12 months+ if possible to unlock LTCG treatment.

How do arbitrage funds compare to liquid funds for parking money? Liquid funds suit money needed within days-to-weeks, at stable, low, slab-taxed returns. Arbitrage funds suit 3 months+ and, for higher tax brackets, typically deliver better post-tax returns via equity taxation. Do arbitrage funds only work well in volatile markets? Volatility tends to widen spreads and support returns, but arbitrage funds have historically delivered moderate, FD-comparable annual returns across both calm and volatile periods — the monthly number moves more than the annual one.

Are arbitrage funds better than fixed deposits? For investors in higher tax brackets holding money for a year or more, arbitrage funds have often given a better post-tax return than FDs, because FD interest is taxed at slab rate every year. But FDs offer a fixed, guaranteed rate and DICGC cover up to ₹5 lakh, while arbitrage fund returns vary and are not guaranteed. Is there an exit load on arbitrage funds? Most arbitrage funds charge a small exit load if you redeem within a short window, commonly around 30 days. Check the scheme information document before investing, and plan to hold for at least a few months so the exit load and the 20% short-term tax rate do not eat into a modest return.
