Debt Funds’ Peaceful NAV Lie: Valuation Games That Cost Retail

Anil chose a debt fund because he is a careful man. Equity swings; debt is steady — look at the NAV, a calm little staircase going up. What Anil cannot see is that some steps of that staircase are painted on. The bonds inside barely trade; their daily prices are, to a meaningful degree, estimates. And wherever there is estimation, there is room for optimism — especially when the optimist’s fees depend on the answer.

The machinery: model-priced serenity

A stock’s price is a fact; a thinly-traded corporate bond’s price is a valuation-model output. When a borrower starts wobbling, the honest move is marking the bond down immediately. The tempting move is holding it at 96 when the market would pay 85 — the NAV stays smooth, redemptions stay calm, and the problem is deferred. Retail investors, who choose debt funds precisely because they read NAV stability as safety, are the last to know the serenity was manufactured.

The Franklin lesson: ₹30,000 crore of “safe”

In April 2020, Franklin Templeton froze six debt schemes overnight — about ₹30,000 crore of investor money, much of it sold as short-duration, liquid-ish parking for conservative savers. The funds had reached for extra yield through low-rated, hard-to-sell paper; when redemptions came, the “liquid” portfolio turned out to be a queue. Unitholders eventually recovered most of it, over years — but the lesson stands: in debt funds, the NAV tells you yesterday’s estimate, not tomorrow’s exit price.

The asymmetry nobody prices

Here is the trade in plain numbers. A “high-yield” debt fund offering 8.5% against a 7% alternative earns you, on ₹10 lakh over three years, about ₹52,000 extra. One credit event side-pocketing 30% of the portfolio costs you ₹3,00,000. You are picking up coins in front of a steamroller, and the coins are taxed at your slab.

The timing games

Watch the sequence in past credit events: large institutional investors exit quietly; the write-down or side-pocket lands after; retail absorbs the marked-down NAV. Add month-end window dressing — risky paper swapped out just before portfolio disclosure dates — and the picture a retail investor sees is curated twice: once by the valuation model, once by the calendar.

How to protect yourself

Decide what your debt allocation is for. If the answer is safety, buy the boring end — overnight, liquid, gilt funds, or plain FDs — where there is nothing to model and nothing to hide. Skip the middle: credit-risk and “high-yield” categories pay you a taxi fare to take a truck’s risk. Check the portfolio, not the past return: anything unrated, unlisted, or concentrated in one promoter group is your warning. And distrust any debt NAV that looks unnaturally smooth in a stressed market — calm is cheap to paint.

Are all debt funds risky then?

No. Gilt and overnight funds hold government paper with transparent prices — the games described here live mostly in credit-risk, medium-duration and “dynamic” categories, where estimation has room to breathe.

How is an FD different from a debt fund?

An FD’s return is a contract; a debt fund’s is an outcome. The fund can beat the FD — but the FD cannot be side-pocketed. Run both through the calculator above and price the certainty gap yourself.
