Equity Savings Fund vs Arbitrage Fund: Which Hybrid Belongs in Your Portfolio?

You have a 6- to 24-month horizon, you want better post-tax returns than a debt fund, and you do not want to take full equity-market risk. Two categories show up in every comparison: equity savings funds and arbitrage funds. They look similar on the surface — both hybrids, both equity-taxed, both pitched as "low-volatility" — but they are structurally very different.

This guide walks through the mechanics, taxation, return drivers, and the situations where each one actually makes sense. Decision-grade, not marketing-grade.

What is an arbitrage fund?

An arbitrage fund exploits price differences between the cash market and the futures market of the same stock. The classic trade: buy 100 shares of a stock in the spot segment at ₹1,000, sell 100 shares' worth of its near-month futures at ₹1,008. By expiry, the two prices must converge — the fund pockets the ₹8 spread, near risk-free in market terms.

Key structural facts (per SEBI's Scheme Categorisation Circular, 2017):

• Minimum 65% in equity arbitrage positions — this gives it equity taxation.
• Remaining 35% typically in debt and money-market instruments.
• Hedged exposure — the fund holds equity and an equivalent short future, so the net equity exposure is close to zero.
• Returns are driven primarily by the cost of carry (short-term interest rate proxy), not by stock direction.

In India, MintByte tracks 141 active arbitrage schemes across 30+ AMCs.

What is an equity savings fund?

An equity savings fund is a more complex hybrid. Per SEBI categorisation it must invest:

• Minimum 65% in equity and equity-related instruments (for equity taxation)
• A meaningful portion in arbitrage positions (hedged)
• A portion in unhedged equity (directional)
• Balance in debt instruments

A typical scheme might hold ~30% net long equity, ~35% hedged arbitrage, ~35% debt. The unhedged equity is the active return driver; the arbitrage and debt portions cushion volatility.

MintByte tracks 132 active equity savings schemes in India.

The structural comparison

Dimension	Arbitrage Fund	Equity Savings Fund
Net equity exposure	~0% (fully hedged)	20-40% (partially hedged)
Return driver	Cost of carry / arbitrage spread	Equity returns + arbitrage + debt accrual
Typical 1Y return regime	5.5-7.5% (proxies short-term rates)	7-12% (varies with equity)
Volatility (annualised)	<1.5%	4-8%
SEBI risk-o-meter	Low to Low-Moderate	Moderately High
Tax treatment	Equity (LTCG >12 mo at 12.5%; STCG 20%)	Equity (same as above)
Minimum holding for tax efficiency	12 months	12 months
Suitable horizon	3-12 months	12-36 months

Taxation — the single biggest differentiator from debt funds

Both arbitrage and equity savings funds are taxed as equity mutual funds under the Income Tax Act (Section 112A / 111A), provided they maintain the 65%+ equity allocation. Post the 2024-25 budget:

• Short-term capital gain (STCG) — held <12 months: 20%
• Long-term capital gain (LTCG) — held >12 months: 12.5% (with ₹1.25 lakh annual exemption across all equity capital gains)

Contrast this with a debt fund held >24 months, which now also has no indexation benefit and is taxed at slab rate. For an investor in the 30% slab parking ₹10 lakh for 13 months:

Vehicle	Pre-tax assumed return	Post-tax (30% slab)
Savings account	3.5%	2.45%
1Y Fixed Deposit	7.0%	4.9%
Liquid Fund	6.8%	4.76%
Arbitrage Fund (>12mo)	6.5%	5.69% (post 12.5% LTCG)
Equity Savings (>12mo)	9.0% (illustrative)	7.88%

Illustrative; actual returns vary. Past performance is not indicative of future returns. Tax position depends on individual circumstances and ₹1.25 lakh exemption usage.

When to use an arbitrage fund

• Emergency-fund extension beyond a liquid fund, where you can absorb 1-2 days redemption settlement.
• Short-term parking (3-12 months) of windfalls — bonus, ESOP sale proceeds, real-estate consideration.
• High-tax-bracket investors for whom the equity tax wrapper materially beats slab-rate debt taxation.
• When you want near-zero volatility with marginally better post-tax than a liquid fund.

What an arbitrage fund is not: a substitute for a savings account. It can have low-single-digit drawdowns; T+1 redemption (not instant); subject to the 1-day exit-load window most schemes apply.

When to use an equity savings fund

• First-time hybrid investor stepping out of FDs but not ready for full equity.
• 12-36 month goal — child's school admission, planned car purchase, vacation fund — where you want some equity participation but cannot afford a 30% drawdown.
• Retiree's growth bucket alongside SWP-friendly debt funds.
• As a glide-path vehicle — accumulating in equity savings, gradually rotating into pure equity over 2-3 years as comfort grows.

What an equity savings fund is not: a liquid-fund substitute. Drawdowns of 5-10% are possible in a sharp equity correction.

Common mistakes investors make

1. Using an arbitrage fund instead of a liquid fund for true emergencies

Arbitrage funds typically apply a 1-day exit load and have T+1 settlement. A liquid fund has instant redemption (up to ₹50,000/day or 90% of folio, whichever lower). Match the vehicle to the urgency.

2. Treating an equity savings fund as "almost a debt fund"

It is not. The 25-40% unhedged equity portion can fall meaningfully in a sharp correction. Investors who entered equity savings funds in late 2019 with debt-fund expectations were surprised in March 2020.

3. Ignoring the expense ratio

Arbitrage spreads are thin — often 30-60 bps annualised on the hedged portion. A 0.8% expense ratio Regular plan eats meaningfully into the trade. Direct plans typically save 30-50 bps versus Regular and are nearly always the right choice for arbitrage funds. Check both plan types at /mf-screener/.

4. Not modelling the post-tax return correctly

The arbitrage-vs-FD comparison only holds for investors in the 20%+ tax slab. For investors in the 5% or 10% slab, a 1-year FD can be competitive after considering DICGC insurance up to ₹5 lakh.

How to research candidates on MintByte

The MintByte MF Screener lets you filter to either sub-category in one click:

• Arbitrage — filter by sub_category = Hybrid Scheme - Arbitrage Fund. Sort by 1-year rolling return median.
• Equity Savings — filter by sub_category = Hybrid Scheme - Equity Savings. Look at the equity-allocation history on the scheme page to confirm consistency.

For each shortlist: 1. Verify the fund manager has been on the scheme for at least 3 years. 2. Compare TER to category median. 3. Check rolling-return consistency across 3-year windows (not just trailing 1-year). 4. For arbitrage — confirm the AUM is large enough (~₹500 cr+) to source meaningful arbitrage spreads. 5. For equity savings — examine downside-capture during 2020 and 2022 corrections.

Frequently asked questions

Q1. Are arbitrage funds risk-free? No. They have low market risk because positions are hedged, but they are not risk-free. Risks include credit risk on the debt portion, operational risk in trade execution, and a small basis risk if a future does not converge cleanly with spot. SEBI's risk-o-meter typically places them in Low or Low-to-Moderate.

Q2. Can an equity savings fund lose money? Yes. The unhedged equity portion (typically 20-40% of AUM) is exposed to market movements. In sharp corrections, equity savings funds have historically drawn down 5-10%. They are not capital-protection products.

Q3. Which is better for tax-saving — arbitrage or equity savings? Both are equity-taxed under SEBI categorisation rules (if 65% equity threshold maintained), so neither has a tax advantage over the other. Both beat debt-fund taxation for investors in the 20%+ slab on horizons over 12 months.

Q4. How much should I allocate to either of these? Depends on your liquidity ladder and risk tolerance. A common framework: 1-3 months of expenses in a liquid fund, 6-18 months of additional cushion in arbitrage, and 12-36 month goals in equity savings. Calibrate to your own cash-flow rhythm.

Q5. Should I prefer Direct or Regular plans? Almost always Direct, especially for arbitrage where the return is in tight basis-point territory. The TER difference of 30-100 bps compounds materially over the holding period.
