Bond defaults and downgrades are becoming daily occurrences and these would only increase if we do not see corporate earnings driven stock market movement. The latest is Reliance Home Fin & Reliance Commercial Fin. Each time there is a change in the credit rating of a bond, the NAV of the debt funds that hold it falls sharply*. So a natural question to ask is, can Banking & PSU debt funds be used to avoid credit risk?

The assumption being that debt funds holding banking and PSU debt funds are less susceptible to rating changes and risk of default. Let us find out if this is possible. Avoiding credit risk and interest rate risk is quite possible and easy too. Why our AMCs are not taking this up is baffling: Open Letter to AMCs: Why are you not pushing Risk-free Debt funds enough?

Banking & PSU Debt Funds: Can they be used to avoid credit risk?

What is a Banking & PSU Debt Fund?

This is the official definition: An open-ended debt scheme predominantly (min 80%)  investing in Debt instruments of banks, Public Sector Undertakings, Public Financial Institutions. Before we discuss more, we need to understand the two main types of debt fund risk.

What is credit risk in mutual funds?

When the repaying ability of a bond issuer goes down, the value of the bond in the market goes down. Proportionally, the NAV of the fund holding that bond would also fall. Read more: Understanding Credit Rating Risk in Debt Mutual Funds

What is interest rate risk in mutual funds?

The price of a bond in the market depends on demand and supply. In a simplistic scenario, when interest rates fall, existing bonds (with a higher rate) become more in demand and the NAV would increase and vice versa. Read more: Understanding Interest Rate Risk in Debt Mutual Funds

How oil price affects the bond market

Other factors also play a role. Although RBI has reduced the repo rate by 0.5% this year, bond prices have fallen since April because of an increase in oil price (and fear it could increase more).  Thus this results in lower demand for bonds with more than a year in tenure, as investors cannot afford to lock in money. Thus the NAV falls.

Can Banking & PSU debt funds be used to avoid credit risk?

Short answer: No. Long answer: Even if we assume (incorrectly) that PSUs and banks will not default, these funds can still hold 20% of risky bonds and so things can still get pretty bad. While shopping for a banking and PSU fund (if you want one, long term goals only) focus on 3-star funds and check out their portfolio holding history. Why?

Well, a fund which sticks only to banking and PSU bonds of good rating will have fewer stars! Unfortunately, there are other problems too.

Interest rate risk in banking and PSU debt funds

Even if we assume these funds hold safe debt, the bonds are a few years in duration. This means they are susceptible to interest rate risk. Unlike credit risk, this can pull down the NAV on a daily basis (by a much smaller amount though). Check out the following two screenshots from Value Research of banking and PSU funds from Axis and L&T.

The fall in NAV since April is due lower demand for such bonds triggered by oil prices. The NAV for both funds moved up a bit when RBI dropped the interest rate fro 6.25% to 6%. Often such upward or downward movement occurs before the actual event in anticipation – what people like to call as “market pricing in the event”.

Thus, if you want to choose banking and debt funds, you must be ready to face such interest rate risk. Question is, are you? Most debt fund investors are not. They want higher than FD returns, lower tax and no risk. Classic wanting to eat the cake and have it too syndrome.

  1. This is very useful info regarding debt fund. Can you please post a topic with your view on which is best option among saving a/c, bank FD vs nps tier 2 account in terms of liquidity , interest and credit risk if we only invest the whole amount in govt. bond

    1. My two cents worth : Govt bonds also carry interest rate risk though practically zero credit risk. Invest if you can stomach the volatility. Know the average maturity and modified duration well. If the interest rates rise by 1%, bonds with ten year maturity can fall by 10%!! and vice versa.

  2. They aren’t safe Professor. Invested in one such fund and took a hit because of IL&FS.

    My fund invested in Jorabat Shillong Expressway Ltd, a joint venture between IL&FS Transportation Networks Ltd (ITNL) and Ramky Infrastructure Ltd.

  3. Thank you.. I have seen your previous video on debt mutual fund in which you advised that we should be willing to stay invested for at least 5 times the time to maturity…

    My question is, in a typical case of fall of interest rate for debt mutual funds, how long does it take for NAV to recover? Does it depend on the maturity duration? How can I get a sense of how much time it will take to recover, so that I can be prepared to take interest rate risk?
