**Quick Answer:** For individuals in the 30% or 39% income tax slab, Arbitrage Funds generate significantly higher post-tax returns than Bank Fixed Deposits (6.5%–7.0% net vs 4.8%–5.0% net). While both offer low volatility, Arbitrage Funds are taxed as equity (12.5% LTCG above ₹1.25 Lakh exemption after 1 year), whereas FD interest is taxed at your full slab rate.
Since the Indian government abolished indexation benefits on debt mutual funds in April 2023, high-income earners have struggled to find safe, tax-efficient parking grounds for cash surpluses. Arbitrage funds have emerged as the primary solution.

- Arbitrage Fund (7.4% p.a.): Pre-tax Gain: ₹74,000 | Long Term Capital Gains Tax (LTCG): ₹0 (Because ₹74,000 falls well within the ₹1,25,000 annual exemption limit!) | In-Hand Post-Tax Return: ₹74,000 (Net 7.40%)

How Do Arbitrage Funds Generate Risk-Free Returns?
An arbitrage fund exploits temporary price discrepancies between the cash (equity spot) market and the derivative (futures) market. For instance, if Reliance stock trades at ₹3,000 in the spot market and its month-end futures contract trades at ₹3,020, the fund simultaneously buys spot and sells futures.
At monthly contract expiry, the cash and futures prices converge perfectly to the exact same price. The ₹20 spread is locked in as guaranteed profit, completely insulated from whether the broader stock market crashes by 500 points or rallies by 1,000 points.
Comparison: Arbitrage Funds vs Fixed Deposits
Key operational differences:
- Taxation: FD taxed at income slab (up to 39%); Arbitrage taxed at 12.5% LTCG (>1 yr) or 20% STCG (<1 yr).
- Liquidity: FDs charge a 0.5%–1% premature withdrawal penalty; Arbitrage funds usually have only a 15 to 30-day exit load (0.25%), after which withdrawals are 100% free.
- TDS Deductions: Banks automatically deduct 10% TDS on FD interest; mutual funds deduct zero TDS for resident Indian investors upon redemption.
When to Stick with Bank FDs
Bank FDs remain superior for investors in the 0% or 10% tax bracket, senior citizens who enjoy a ₹50,000 interest deduction under Section 80TTB, and individuals seeking DICGC government deposit insurance guarantee up to ₹5 Lakh.
Frequently Asked Questions
Negative returns over monthly or yearly holding periods are extraordinarily rare in Indian arbitrage funds.

Most Indian AMCs charge an exit load of 0.25% if redeemed within 15 to 30 days of purchase. After 30 days, there is zero exit load.
