Arbitrage fund vs liquid fund for short-term parking
Arbitrage funds vs liquid funds is a comparison particularly relevant for Indian retail investors managing short-term cash in high tax brackets, where the arbitrage fund ’s equity-oriented tax treatment provides material advantage over liquid funds despite similar risk-return profiles.
The critical insight: arbitrage funds are equity-oriented for tax purposes (12.5% LTCG above Rs 1.25 lakh exemption) while liquid funds are debt-oriented (slab rate post-2023). For high-tax-bracket investors, this differential favours arbitrage funds for short-term parking even though both have similar low-volatility profiles.
Key differences
| Dimension | Arbitrage Fund | Liquid Fund |
|---|---|---|
| Strategy | Cash-futures arbitrage | Short-term debt |
| Risk | Very low (arbitrage spread) | Very low (high-quality short debt) |
| Returns | 5-7% (similar to liquid) | 5-7% |
| Tax classification | Equity-oriented (>65% equity per regulations) | Debt-oriented |
| Tax rate (LTCG, >12 months) | 12.5% above Rs 1.25 lakh exemption | Slab rate |
| Tax rate (STCG, ≤12 months) | 20% | Slab rate |
| Lock-in suggestion | 12 months for LTCG eligibility | None |
How arbitrage funds work
Arbitrage funds exploit price differences between cash market and futures market:
- Buy stock in cash market at lower price.
- Simultaneously sell futures of same stock at higher price.
- Lock in the spread as risk-free return.
- At futures expiry, cash and futures converge; arbitrage profit realised.
The strategy is essentially risk-free at scheme level (the arbitrage spread is locked in at trade entry).
Tax efficiency comparison
Worked example: high-tax-bracket investor
Investor in 30% tax bracket parks Rs 10 lakh for 14 months:
Liquid fund (6% return, slab rate tax):
- Gain: Rs 70,000 (over 14 months).
- Tax at 30% slab: Rs 21,000.
- Net: Rs 49,000.
Arbitrage fund (6% return, LTCG):
- Gain: Rs 70,000.
- After Rs 1.25 lakh LTCG annual exemption (assuming this is the only LTCG): Rs 0 taxable.
- Net: Rs 70,000.
For this scenario, arbitrage fund delivers approximately Rs 21,000 higher net return (Rs 70,000 vs Rs 49,000) for the same gross return, simply due to tax-efficiency.
When arbitrage is better
- High tax bracket (20%+): Tax advantage material.
- 12+ month horizon: For LTCG qualification.
- Equity-oriented exposure desired: Some investors prefer the equity classification.
When liquid is better
- Very short horizon (< 3 months): Arbitrage less suitable.
- Low tax bracket: Tax differential modest.
- Daily liquidity priority: Liquid offers T+0 redemption.
Risks
Arbitrage fund specific risks
- Spread compression: Low-volatility market periods compress arbitrage spreads, reducing returns.
- Futures liquidity: Specific futures contracts may have lower liquidity.
- Manager-execution risk: Spread capture depends on manager skill.
Liquid fund risks
- Credit risk (minor for high-quality liquid funds).
- Interest-rate risk (minor for very short tenors).
- Liquidity stress (per Franklin Templeton 2020 episode ).
Practical recommendation
- Short-term parking < 3 months: Liquid fund.
- 12+ month parking, high tax bracket: Arbitrage fund.
- Mixed approach: Liquid for emergency cash + arbitrage for tax-efficient parking.
