Arbitrage Funds: The Smart Alternative to FDs [EasyDNNnews:PaidContentStart]
Reserve Bank of India’s recent rate cuts have only reinforced expectations of a softer interest rate regime ahead. Coupled with the tightening of debt mutual fund taxation, the traditional appeal of these investment avenue is eroding, particularly for those in higher tax brackets. Against this backdrop, arbitrage funds are gaining renewed traction— offering a unique combination of low volatility, steady returns, and significantly better tax efficiency
With fixed deposit (FD) rates gradually inching downward, reflected in the country’s largest lender’s highest FD rate now standing at just 6.7 per cent—investors are once again re-evaluating their liquid fund parking strategies. This shift is likely to be further accelerated by the Reserve Bank of India’s recent monetary easing, including repo rate and CRR cuts, which signal a softer interest rate environment going forward. As a result, traditional safe havens like FDs are losing their appeal, especially for investors in higher tax brackets who are also grappling with tighter post-Budget debt mutual fund taxation norms.
Enter arbitrage funds—an increasingly favoured option that strikes a balance between stability and tax efficiency. Once considered the quiet workhorses of the mutual fund universe, they are making a strong comeback into investor conversations—thanks to a decisive shift in tax policy. These funds leverage the price differences between the same securities in different exchanges or cash and futures markets and lock in a spread to generate steady returns, often mimicking the risk profile of ultra-low-volatility debt instruments. These funds typically maintain a near-zero net equity exposure, meaning your capital isn't at the mercy of sharp market movements— making them ideal for conservative investors who still want to enjoy the perks of equity taxation.
But what truly sets them apart is their tax treatment. While interest on FDs is taxed as per one’s income slab (up to 39 per cent in certain cases), arbitrage funds enjoy equity-like taxation, with long-term capital gains taxed at just 12.5 per cent. That’s a potential post-tax edge of 1.5–2 per cent for high-net-worth individuals. As falling interest rates squeeze traditional returns and taxation tilts the scale, arbitrage funds are emerging as the smart investor’s answer to parking capital efficiently. This article explores why, in today’s macroeconomic and tax landscape, arbitrage funds make more sense than ever before.
Tax Treatment That Trumps Debt Funds
Mutual funds with less than 65 per cent equity exposure lost indexation benefits and are now taxed at your income slab rate—up to 39 per cent for high-income investors. Arbitrage funds, however, are treated as equity funds as they maintain more than 65 per cent exposure towards equity. That changes everything. This tax edge significantly improves post-tax returns, especially for investors in higher tax brackets.

Arbitrage funds stand out in the current tax landscape primarily because of their classification as equity funds—a distinction that dramatically improves their post-tax returns. While traditional instruments like bank FDs offer predictable pre-tax returns, their earnings are heavily taxed at the investor’s income slab rate. For example, a 3-year SBI FD yielding 6.05 per cent gets reduced to just around 4.16 per cent after a 31.2 per cent tax outgo for investors in the highest bracket. It is not even keeping up with inflation. In contrast, arbitrage funds, with their equity taxation benefits, offer a far more efficient route to wealth preservation and short-term growth.
Consider the numbers. A typical arbitrage fund delivers around 7.5 per cent in one year. When taxed under the short-term capital gains (STCG) regime at 20 per cent (excluding cess), the post-tax return still stands strong at approximately 6 per cent—almost 2 percentage points higher than an FD. The gap widens further over the long term. Arbitrage funds held for over a year qualify for long-term capital gains (LTCG) taxation at just 12.5 per cent, after the `1.25 lakh annual exemption. This brings the effective post-tax return close to 6.5 per cent, making them one of the most tax-efficient instruments for conservative investors looking for low-volatility alternatives to debt. In a high-tax environment, this efficiency could make a significant difference to your bottom line.
Returns of the arbitrage funds are stable as they offer an added layer of agility through their dynamic allocation mechanism. Fund managers have the discretion to switch between arbitrage opportunities in the equity markets and debt instruments (up to 35 per cent of the portfolio) depending on prevailing market conditions. This ability to tactically shift allocation enables them to capture attractive risk-free spreads during stable markets while using the debt component to enhance yield in lowvolatility phases. Unlike some Hybrid Funds that follow static allocation models or are more exposed to equity market movements, arbitrage funds maintain a balanced and responsive approach—providing investors with a unique blend of flexibility, tax efficiency, and risk mitigation.

Risk Matters
While arbitrage funds are not entirely risk-free, their structure inherently cushions them from direct market volatility. Unlike traditional equity funds that rely on directional market movements, arbitrage funds earn returns by exploiting price differences between the cash and futures markets. This strategy provides a layer of volatility protection, especially during uncertain or sideways market conditions. The spreads they capture are generally more predictable in stable markets, offering a sense of consistency in returns. Additionally, arbitrage funds tend to bring a level of portfolio stability during broader market corrections, making them a valuable component for conservative investors. When combined with the liquidity and transparency typically associated with mutual funds, arbitrage funds emerge as an attractive low-risk investment avenue.

Arbitrage funds exhibit a relatively low average standard deviation of 0.54, making them one of the more stable categories among debt and hybrid funds.
Another feature of arbitrage funds is the high degree of liquidity they offer—especially when compared to traditional instruments like FDs or certain types of hybrid funds. Unlike FDs, which come with rigid lock-in periods, arbitrage funds allow investors to redeem their investments within a few days.
Although an exit load may apply if redeemed within a short period—typically ranging from 0.25 per cent to 1 per cent for redemptions made within 7 days to up to 1 year depending on the scheme—it is still far more flexible than the penalties or premature withdrawal conditions attached to FDs. This makes arbitrage funds an ideal solution for investors who may need access to their funds at short notice, while still aiming for tax-efficient returns.
Who Should Consider Arbitrage Funds?
High-income investors (30 per cent+ tax bracket) looking for low-volatility options
If you're in the highest income tax slab, traditional interest income from fixed deposits and savings schemes gets taxed heavily. Arbitrage funds, taxed as equity-oriented funds, offer a more tax-efficient alternative.
Conservative investors seeking better-than-FD post-tax returns
While fixed deposits offer guaranteed returns, they fall short in terms of tax efficiency. Arbitrage funds, though market-linked, are inherently low-risk as they simultaneously buy and sell the same security in different markets to lock in profits. This structure helps generate relatively consistent returns, often higher than post-tax FD returns, without exposing the investor to the full brunt of market volatility.
Investors with a 3–12 month investment horizon who don’t want equity market risk
Arbitrage funds are ideal for short- to medium-term parking of funds. If you’re planning for a financial goal within a year—be it a family event, travel plan, or down payment—but don’t want your corpus to fluctuate with the market, these funds provide a smart middle path. They offer equity taxation benefits while behaving more like debt in terms of risk and volatility.
In Conclusion
With the taxation carpet pulled out from under traditional debt funds, arbitrage funds offer a unique blend of safety, liquidity, and tax efficiency. As financial planning in the new tax regime demands smarter instruments, arbitrage funds could become your portfolio’s most underrated ally. Whether you’re looking for short-term deployment, post-tax yield enhancement, or simply a smarter way to park idle cash, arbitrage funds offer a thoughtful and strategic solution.
