The wrong comparison

5.25% against 8.05% is not a yield gap. It is two different questions.

Sell a plot of land at a gain and there are two broad routes. Invest the gain in bonds notified under Section 54EC of the Income-tax Act and the long-term capital gains tax does not fall due; the money is locked for five years at 5.25%. Or pay the tax and put what is left anywhere, including the RBI Floating Rate Savings Bond 2020 (Taxable), which pays 8.05% for July–December 2026 and is sovereign.

Comparing the coupons puts 54EC 280 basis points behind and ends the discussion. That is the wrong test, because 54EC’s benefit is not a coupon at all. It is a one-time increase in the capital you get to deploy. At a 12.5% LTCG rate plus 4% cess — an effective 13.0% — the choice on a ₹50 lakh gain is between compounding ₹50.00 lakh at 5.25% and compounding ₹43.50 lakh at 8.05%. The only honest comparison is terminal wealth.

So the instrument survives its own bad press. On a five-year view, the tax shield is worth more than 280 basis points of coupon, and every investment-grade alternative loses to it. The 54EC route ends at ₹60.09 lakh; the RBI bond, the obvious “higher-yielding” answer, ends ₹3.13 lakh behind despite paying half again as much interest.

The breakeven

To beat it you have to buy credit risk, not yield.

The number that matters is the pre-tax yield an alternative must earn to reach ₹60.09 lakh from a post-tax ₹43.50 lakh base. At a 30% slab over five years it is 9.92%. Nothing rated AAA or AA in the Indian market clears that. A-rated paper does, at 9.5–11.5%, which is the point: the crossover sits inside the ratings band where default becomes a real possibility, and this model does not price default at all. An A-rated NCD beating 54EC by ₹0.96 lakh is not an edge; it is compensation for a risk the table refuses to quantify.

The breakeven is also not stable. The shield is a one-time head start, so stretching the horizon dilutes it:

At ten years the breakeven falls to 7.72% and AA paper clears it. The instrument is strongest exactly at its lock-in length and weakens after — which is the opposite of how it is usually sold.

Where the exemption actually goes

₹6.5 lakh is granted. ₹4.25 lakh comes straight back.

Here is the part that changes what the instrument is. Nothing in Section 54EC sets the coupon at 5.25%. The statute is silent on pricing; the rate is set by each issuer’s board. REC and PFC raise five-year AAA paper in the market at around 7.46%. The 54EC window hands them the same money at 5.25% — roughly 220 basis points below market.

Price that gap. Repricing 54EC at 7.46% with everything else unchanged lifts the terminal value from ₹60.09 lakh to ₹64.33 lakh. The difference, ₹4.25 lakh, is what the below-market coupon costs the investor over the five-year lock — on identical credit, identical liquidity, identical tenure. Against the ₹6.50 lakh of tax the exemption saved, the investor keeps ₹2.25 lakh, or 34.6% of the headline number. The rest is captured by five public-sector issuers as cheap funding.

Read against the honest alternative — pay the tax, buy AAA PSU paper at 7.46% — the investor is ₹4.12 lakh ahead. That is the real, decision-relevant benefit of Section 54EC: not ₹6.5 lakh, and not a 280-basis-point sacrifice either, but about ₹4 lakh on a ₹50 lakh gain.

The gate is a notification, not the Act

It has already been opened twice in the last eighteen months.

The obvious reform ask — let capital gains go into something that yields more — sounds like it needs Parliament. It does not. The Explanation to Section 54EC defines a “long-term specified asset” as a bond redeemable after five years issued by NHAI or REC, or any other bond notified by the Central Government in this behalf. That notification power is live and in recent use:

The IREDA notification is the useful precedent. It came with a condition — proceeds may fund only renewable-energy projects capable of servicing debt from their own revenues, without relying on State Government support — which shows CBDT is willing to attach end-use tests rather than simply admitting a new borrower. The template for widening the set already exists and was used fifteen months ago.

But widening the set does not, by itself, raise the coupon. All five issuers price at exactly 5.25%, and that uniformity is structural rather than coincidental: with a ₹50 lakh cap per PAN per year, a single issuer offering 5.50% would capture the entire flow. Competition on coupon cannot emerge from a capped, undifferentiated instrument. Only a rule can move it.

The cap that has not moved in twelve years

₹50 lakh in 2014 money is ₹34 lakh today.

The ₹50 lakh ceiling was set by the Finance (No. 2) Act 2014 and has not been revised since. Deflating it by this blog’s own wholesale price series — all-commodities WPI on the 2011-12 base, 114.1 in April 2014 against 167.6 in April 2026 — the cap is worth ₹34.0 lakh in the prices of the year it was written, an erosion of 31.9%. Measured against urban property prices rather than wholesale goods, the erosion is far steeper, because the asset class the section exists to serve is exactly the one that has outrun the index.

The cap is also the reason the coupon question matters at all. If it were ₹5 crore, a 220-basis-point discount would be a large transfer. At ₹50 lakh it is capped at about ₹4.25 lakh per taxpayer per year — small individually, and the aggregate depends on take-up that is not published.

What a reform ask would look like

Four changes, none needing an amendment to the Act.

1. A coupon formula instead of a board decision. Notify future issuers subject to a pricing rule — the five-year G-sec less a fixed spread, reset half-yearly, on the model the RBI already uses for the Floating Rate Savings Bond (NSC rate plus 35 basis points). This keeps the subsidy to the issuer but caps the clawback at a published number instead of leaving it to be discovered by arithmetic.

2. Widen the notified set with end-use conditions. NaBFID and municipal bonds are the obvious candidates. The HUDCO and IREDA notifications show the mechanism and the conditionality template both work.

3. Index the ₹50 lakh cap. Twelve years without revision is a real-terms cut of roughly a third that no one has had to vote for.

4. Allow transferability after the lock-in. 54EC bonds are non-transferable and cannot be pledged, so the five-year lock is absolute. Permitting transfer after year five costs the exchequer nothing — the exemption has already vested — and restores an exit.

What this model does not do

Four limits, stated before anyone quotes the table.

Credit risk is not priced. This is the largest limitation and it points in one direction: it flatters everything below AAA. A BBB NCD appears ₹3.89 lakh ahead of 54EC because the model treats a 12.25% coupon as certain. It is not.

Coupon income only. Price appreciation on listed bonds is excluded. Listed bonds held over twelve months attract 12.5% LTCG on gains; unlisted bonds and market-linked debentures are deemed short-term under Section 50AA and taxed at slab regardless of holding period. 54EC bonds and the RBI FRSB are non-transferable, so no capital gains event can arise on either.

A floating rate is held flat. The RBI bond’s 8.05% resets every 1 January and 1 July at the NSC rate plus 35 basis points. Running it flat for five years is an assumption, not a forecast, and it is the same mistake this blog flagged in the wholesale-price series: a rate that held steady through a calm stretch is not a description of the next five years. If NSC rates fall, the FRSB row weakens and 54EC’s lead widens.

One yield in the table is a resolved conflict and one is an estimate. Secondary-market yields on tax-free PSU bonds were quoted by two credible sources roughly 100 basis points apart. Checking live ISIN-level quotes settles it near the lower end — a PFC 8.67% 2033 at about 5.2% and an IRFC 8.63% 2029 at about 5.11% — so 5.15% is used here, which moves tax-free PSU bonds from fourth place to eighth. State Development Loans were dropped from the table entirely because the only figure available was a spread estimate with no primary quote behind it.
