Arbitrage mutual funds in India are quietly delivering ~7% annual returns with FD-like risk - but with dramatically better post-tax outcomes for anyone in the 20% or 30% income tax slab. For a salaried investor earning ₹15 lakh+, parking ₹10 lakh in an arbitrage fund for 12 months can leave roughly ₹21,000 more in hand versus an equivalent bank FD, purely due to equity-style taxation under Sections 111A and 112A of the Income Tax Act. The category has exploded as a result: assets under management crossed ₹2.75 lakh crore in November 2025, growing nearly 40% year-on-year per AMFI data, with net inflows of ₹55,374 crore in just seven months. The reason is structural - Budget 2023 stripped debt funds of LTCG benefits, while Budget 2024 confirmed arbitrage funds remain equity-taxed (12.5% LTCG, 20% STCG). With RBI holding the repo rate at 5.25% and FD rates plateauing around 6.5%, the case for arbitrage as the new short-term parking vehicle has never been stronger. This article unpacks how they work, the leading schemes, the post-Budget 2024 tax math, and where they fit alongside liquid, overnight, ultra-short-duration, and equity savings funds.
How Arbitrage Funds Actually Make Money
An arbitrage mutual fund is a SEBI-categorised hybrid scheme that earns its return by simultaneously buying a stock in the cash market and selling the same stock in the futures market, locking in the price differential - known as the spread or basis - until expiry day. Indian stock futures typically trade at a small premium to the spot price because of the cost-of-carry (the interest cost of holding a stock until expiry, net of expected dividends). That premium is the fund's raw material.
Worked example: Suppose Reliance trades at ₹1,000 in the cash market and the current-month future trades at ₹1,015. The fund buys 1 lot in cash at ₹1,000 and sells 1 lot of futures at ₹1,015. On the last Thursday of the month, futures and cash prices converge. Whether Reliance ends at ₹900, ₹1,015 or ₹1,100, the fund still pockets exactly ₹15 of spread per share - the directional exposure is fully hedged.
Across hundreds of such positions in the ~190 F&O-eligible stocks, rolled monthly, the strategy delivers debt-like returns with equity-like tax treatment.
Per SEBI's 2017 categorisation circular, at least 65% of net assets must sit in equity and equity-related instruments, which is what triggers equity taxation. The remaining 25-35% is parked in T-bills, TREPS, certificates of deposit and short-duration debt to provide incremental yield when arbitrage spreads thin out. Each AMC is allowed only one arbitrage scheme. Standard deviation for the category sits around 0.83% (versus 12-15% for diversified equity funds), and SEBI's risk-o-meter classifies these funds as "Low" or "Moderately Low" risk.
Risks: Real but Contained
Spread compression in calm, low-volatility markets can drag returns toward 5%, as happened in parts of 2017 and 2024. The strategy depends on F&O liquidity and a positive cost-of-carry - when futures trade at a discount (backwardation), mutual funds cannot exploit it because they are barred from short-selling the cash leg. Portfolio turnover often exceeds 1,500%, so transaction costs (STT, GST, brokerage) eat meaningfully into gross returns. Most schemes also impose a 0.25-0.50% exit load if redeemed within 15-30 days, making them unsuitable for sub-monthly parking.
Top Arbitrage Funds in India: April 2026 Snapshot
The category is unusually homogeneous - 1-year returns across the top ten are bunched within a 30-basis-point range, and 3-year CAGRs cluster between 7.6% and 7.8%. Fund choice matters less than expense ratio, scheme size, and exit-load terms, because all schemes essentially harvest the same market-wide spread.
| Fund (Direct Plan - Growth) | AUM (₹ Cr) | 1-Yr | 3-Yr CAGR | 5-Yr CAGR | Expense Ratio | Exit Load |
|---|---|---|---|---|---|---|
| Kotak Equity Arbitrage Fund | 71,931 | 7.0% | 7.8% | 6.7% | 0.44% | 0.25% if <30 days |
| SBI Arbitrage Opportunities Fund | 43,574 | 7.0% | 7.6% | 6.7% | 0.40% | 0.25% if <1 month |

| Bandhan Arbitrage Fund | 8,828 | 6.9% | 7.7% | 6.5% | 0.35% | 0.25% if <15 days |
Data as of April 2026, sourced from Groww, Tickertape, AMFI and AMC factsheets. Regular plan returns are typically 20-25 bps lower.
Kotak Equity Arbitrage Fund dominates by AUM at over ₹71,000 crore - bigger than the next two competitors combined - which gives it an edge in deploying derivative limits efficiently. On pure 1-year returns, Tata Arbitrage and Aditya Birla Sun Life Arbitrage lead at 7.2%, both with the lowest expense ratios in the table at 0.31%. For investors picking a single scheme, low expense ratio plus a short exit-load window (15 days versus 30) is the most reliable differentiator.
Taxation After Budget 2024: The Rule That Changes Everything
The Finance (No. 2) Act, 2024, presented on 23 July 2024, materially reshaped capital gains taxation in India. Arbitrage funds, because they hold ≥65% equity, continue to enjoy equity taxation - but the rates moved up.
Short-Term Capital Gains (STCG)
For redemptions on or after 23 July 2024, short-term capital gains (holding under 12 months) are taxed at a flat 20% (raised from 15%) under Section 111A.
Long-Term Capital Gains (LTCG)
Long-term capital gains (holding over 12 months) are taxed at 12.5% (raised from 10%) on gains exceeding ₹1.25 lakh per financial year (raised from ₹1 lakh) under Section 112A. The 12-month holding-period threshold is unchanged. Surcharge on equity LTCG is capped at 15%, even for ultra-HNI investors - a critical detail that makes arbitrage even more attractive at the top of the income pyramid.
The Contrast with Debt Funds
The contrast with debt funds is stark. Since 1 April 2023, debt fund units acquired after that date are taxed entirely at slab rate, regardless of holding period - no LTCG benefit, no indexation. For an investor in the 30% slab, that means the same 7% return is taxed at 31.2% in a liquid fund but at 13% (or zero, within the ₹1.25 lakh exemption) in an arbitrage fund.
The ₹1.25 lakh exemption is shared across all equity gains in a year, not per-fund. STT applies on redemption (0.001% on the seller), which is what qualifies the fund for equity treatment under Section 112A. There is no TDS on capital gains for resident investors - only on IDCW above ₹5,000 per AMC per year (10% under Section 194K).
A practical illustration: an investor putting ₹10 lakh in an arbitrage fund and earning ₹70,000 over 13 months pays zero tax, because the entire gain falls within the ₹1.25 lakh annual LTCG exemption. The same ₹70,000 of FD interest costs a 30%-bracket investor over ₹21,000 in tax.
How Arbitrage Funds Compare to Other Short-Term Options
The five categories most often confused with arbitrage funds serve genuinely different purposes. The table below summarises where each fits.
| Category | Typical Return | Risk | Tax Treatment | Ideal Horizon | Best Use |
|---|---|---|---|---|---|
| Arbitrage | 6.5-7.5% | Low (market-neutral) | Equity (20% STCG / 12.5% LTCG) | 3-12+ months | Tax-efficient parking for 20%+ slabs |
| Liquid | 7.0-7.3% | Low | Debt (slab rate) | 1 day - 3 months | Emergency fund, idle cash beating savings account |
| Overnight | 6.5-7.3% | Lowest | Debt (slab rate) | 1 day - 1 week | Treasury parking, regulatory deposits |
| Ultra Short Duration | 6.8-7.4% | Low-Moderate | Debt (slab rate) | 3-12 months | Slight return pickup over liquid |
| Equity Savings | 8-12% (variable) | Moderate | Equity (20% STCG / 12.5% LTCG) | 3-5 years | Conservative equity exposure with tax efficiency |
The decisive split is equity versus debt taxation. Liquid, overnight and ultra-short funds all suffer from slab-rate taxation post-2023. Arbitrage and equity savings funds retain equity treatment, but only arbitrage is truly market-neutral - equity savings funds carry 20-40% unhedged equity, which adds genuine volatility and makes them unsuitable as FD substitutes. Arbitrage is the only category that combines debt-like stability with equity-like taxation, which is precisely why net inflows hit a record ₹15,702 crore in May 2025 alone, leading every mutual fund category that month.
For ultra-short parking under a month, liquid funds still win on simplicity (no exit load after 7 days, instant redemption up to ₹50,000). For 3-12 month horizons in higher tax brackets, arbitrage takes the prize. For multi-year goals, equity savings or hybrid funds make more sense.
FD Rates in 2025-26: The Ceiling Has Held
With RBI maintaining the repo rate at 5.25% in its April 2026 MPC meeting under a neutral stance, FD rates have largely peaked and are stable-to-falling. Major banks now cluster between 6.25% and 6.50% for 1-3 year tenures.
SBI offers around 6.25% for 1 year, 6.40% for 2 years, and 6.30% for 3 years, with its 444-day "Amrit Vrishti" special at 6.45% (7.05% for senior citizens). HDFC Bank, ICICI Bank and Axis Bank peak between 6.45% and 6.50% across 3-year buckets, with senior citizen rates touching 7.10-7.20%. Among PSU banks, PNB and Bank of Baroda lead with 6.60% on special 444-day buckets. Kotak Mahindra and RBL are the strongest among large private banks at 6.70-6.80%.
Small finance banks remain the yield leaders. Suryoday SFB pays 7.90-8.10%, Jana SFB 7.77%, and Equitas SFB 7.40% on special tenures, with senior citizens earning 50-75 bps more. These deposits are insured by DICGC up to ₹5 lakh per depositor per bank - a real but capped safety net.
TDS on FD interest applies at 10% above ₹50,000 per year for regular depositors and ₹1,00,000 for seniors (raised in Budget 2025), but the final tax liability is at slab rate - TDS is just an advance. Premature withdrawal carries a 0.50-1% interest penalty at most banks, applied retrospectively to the entire holding period.
The Post-Tax Math: Why 30%-Slab Investors Should Care
Here is where the case for arbitrage funds crystallises. Assume a 7% gross return on ₹10 lakh held for 12+ months in both an FD and an arbitrage fund.
| Tax Slab | Effective Tax Rate | FD Post-Tax Return | Arbitrage LTCG Post-Tax | Advantage |
|---|---|---|---|---|
| 5% slab | 5.2% | 6.64% | ~7.00%* | Roughly equal |
| 20% slab | 20.8% | 5.54% | ~7.00%* | +146 bps |
| 30% slab (≤₹50L income) | 31.2% | 4.82% | ~7.00%* | +218 bps |
| 30% + 10% surcharge (₹50L-1Cr) | 34.32% | 4.60% | ~7.00%* | +240 bps |
| 30% + 15% surcharge (₹1-2Cr) | 35.88% | 4.49% | ~7.00%* | +251 bps |
| 30% + 25% surcharge (>₹2Cr) | 39.0% | 4.27% | ~7.00%* | +273 bps |
*₹70,000 gain on ₹10L falls fully within the ₹1.25 lakh annual LTCG exemption, so effective tax is zero.
For a 30%-slab salaried professional, the gap is over 2 percentage points after tax - an enormous advantage in a category where the underlying gross returns are nearly identical. The arbitrage advantage only fades for investors in the 5% slab, where FDs marginally win on simplicity and capital safety.
Liquidity is the second axis where arbitrage quietly outperforms. An FD broken before maturity loses 0.5-1% in interest across the entire holding period, applied retroactively. An arbitrage fund charges 0.25-0.50% only if redeemed within the first 15-30 days; thereafter, redemption is free, with money credited to the bank account in T+1 or T+2 working days. Partial redemptions are seamless - you can pull out exactly the amount needed without breaking the rest, something an FD cannot offer without laddering.
LTCG harvesting tactic: A smart tactic for HNIs is annual LTCG harvesting: every 13 months, redeem up to ₹1.25 lakh of gains, immediately reinvest at the new (higher) NAV, and reset the cost basis. Repeated systematically, this can eliminate the LTCG bill entirely on portfolios up to roughly ₹17.85 lakh.
When FDs Still Win, and Where Caution Is Warranted
Arbitrage funds are not a universal upgrade. For investors in the 5% or 10% slabs, the post-tax math is too close to justify giving up FD's contractual guarantee and DICGC insurance. Senior citizens optimising for guaranteed income are also better served by special-tenure FDs paying 7.05-7.20%, especially in PSU banks where the ₹5 lakh DICGC cover covers a meaningful chunk. For sums needed in under 30 days, the exit load on arbitrage funds wipes out the tax advantage - a liquid fund or sweep-in FD is more efficient.
The other caveat is return predictability. Arbitrage spreads compress in calm, range-bound markets and widen during volatility (when FII selling pushes futures into deeper discount or premium becomes scarce). The category's 7%+ run through 2024-25 reflects an unusually volatile environment; a return to the 5-6% historical average is plausible if markets settle. Returns are not contractually guaranteed, even though daily NAV volatility is minimal.
Conclusion: A Structural Shift, Not a Fad
Arbitrage funds have moved from being a niche product for treasury teams to a mainstream short-term parking vehicle for tax-aware Indian retail investors, and the architecture supporting that shift is regulatory rather than cyclical. Assets under management crossed ₹2.75 lakh crore in November 2025, growing nearly 40% year-on-year.
Budget 2023's removal of debt fund LTCG benefits, combined with Budget 2024's confirmation of equity taxation for arbitrage schemes, has created a permanent post-tax wedge that no FD or liquid fund can close. The 218-basis-point post-tax advantage for a 30%-slab investor is not a marketing claim - it is a direct consequence of how the Income Tax Act now treats Section 50AA debt fund gains versus Section 112A equity gains.
Practical takeaway: Anyone in the 20% or 30% slab parking money for 3 months or longer should evaluate arbitrage funds before defaulting to an FD or liquid fund. Pick a scheme with a low expense ratio (Tata, Aditya Birla Sun Life, or Nippon India all sit at 0.31-0.32%) and a short exit-load window. Hold for at least 12 months to unlock LTCG treatment. Harvest gains within the ₹1.25 lakh annual exemption each March. Done well, this single shift can deliver an extra 1.5-2 percentage points of post-tax return year after year - without taking a single rupee of additional market risk.
