Do Arbitrage funds score over Debt funds post abolition of LTCG and indexation benefits?

Arbitrage funds need to invest a minimum of 65 percent of their corpus in equity-related instruments to qualify for equity taxation. However, since these funds work on the arbitrage principle, they buy stocks in the cash market and simultaneously sell in the futures market at a different price, thereby offsetting the entire net equity position. They also hold about 35 percent in debt instruments. This structure makes arbitrage funds a comparatively low-risk option.

Returns and volatility

Arbitrage funds use low-risk strategies to exploit price inefficiencies between different markets to generate returns.

These have often been compared with liquid funds, given the similar return profile, as can be seen below in comparison of the four largest schemes (by AUM) in both categories:

But after the recent debt fund taxation changes, there is no doubt that given the same return buckets, the arbitrage funds can be more tax-efficient compared to liquid funds if you belong to the higher 20-30 percent tax slab and are looking to hold for more than a year (to qualify for 10 percent LTCG taxation for arbitrage funds).

But before giving the trophy to arbitrage funds, we need to get a bit more into the details.

Given the potential of arbitrage opportunities in the equity markets, at times arbitrage funds can deliver much higher returns than liquid funds. But arbitrage funds can also fluctuate a lot on a daily basis and have poor runs in a short-term (weekly or monthly) basis if the market environment is such.

Also, while arbitrage funds are low-risk investments, their returns can vary depending on market conditions, interest rate scenarios and the available spot-future arbitrage opportunities. A volatile market offers more opportunities to arbitrage funds in general.

Not only that, given the structural nature of arbitrage opportunities, if more players enter the space and come after the opportunity, then the extent of arbitrage (or the opportunity itself) will reduce or cease to exist. So, the size of the opportunities available and the fund size have an impact on how best arbitrage fund managers can generate returns.

Expense ratio spanner

In recent times, the capital market regulator, the Securities and Exchange Board of India (SEBI) has been deliberating about having the brokerage, Securities Transaction Tax (STT), etc. included in the expense ratio of the scheme. If this proposal comes into force, then given the nature of arbitrage funds (which need to trade a lot and have high turnover), this will further negatively impact their returns.

Can you use Arbitrage funds instead of Debt funds?

First things first, arbitrage funds do have an upper hand when it comes to taxation structure. More so, if you as an investor belong to higher tax brackets.

Now comes the key question we started with. The debt fund taxation is no longer attractive. So, does it mean that you can replace all categories of debt funds with arbitrage funds instead?

The answer is no. Let’s see why:

• If you belong to a higher tax bracket and looking to park money in liquid/ultra-short duration/money market funds for a period of about 1 or 2 years, then arbitrage funds are better, given the better taxation and similar pre-tax return structure. This is assuming that short-term volatility in arbitrage funds is acceptable to you.


• If you belong to a higher tax bracket but are instead looking to invest in debt instruments for your long-term debt allocation (for 2-3 or more years), then good debt fund categories and schemes, whose fund managers have a reasonably good track record of maintaining high-quality portfolios, are better options. The short-duration funds generally offer better yields when compared to categories like liquid/ultra-short, etc. And every few years, arbitrage funds would do well due to suitable market conditions, but it is very difficult to predict when that will happen. So in such cases, debt fund categories like short-duration offer more reliable return profiles even on a post-tax basis.


• To be fair, one can even look at having a mix of pure debt funds and good arbitrage funds (in varying allocations) for the debt side of the portfolio.


• Those in lower tax brackets and limited investments can pick debt funds to keep things simple.
