Sovereign Gold Bonds Maturing in 2026: What Holders Actually Earned

Most SGB articles you will read are a forecast: buy this, hold eight years, and here is a hypothetical CAGR. That era is over. The first big tranches issued in 2018 have now hit their eight-year maturity, so we can stop guessing and read the receipt. This post takes one specific bond that matured a couple of months ago, works out to the rupee what a holder actually walked away with, and lines it up against a gold ETF and physical gold bought on the very same day.

The headline: the gold price did most of the heavy lifting, but the parts everyone dismisses as “small” - the 2.5% coupon and the tax-free maturity - are exactly what turned a good gold trade into the best one available.

The tranche we are dissecting

I am using SGB 2018-19 Series I:

• Issue price: Rs 3,114 per gram (online buyers paid Rs 50 less, so Rs 3,064)
• Issue date: 4 May 2018
• Maturity: 4 May 2026 (eight years later)
• Coupon: 2.5% per annum on the issue price, paid every six months

To keep the arithmetic readable I will assume someone bought 100 grams, an outlay of Rs 3,11,400 in May 2018. Scale everything down by 100 if you held a single gram.

One honest caveat up front. The RBI sets the maturity redemption price as the average IBJA closing price of 999-purity gold over the three business days before maturity. I am using a representative redemption price of Rs 9,000 per gram for early May 2026, in line with where domestic gold traded after the 2024-25 run-up. Your exact tranche and exact redemption day will differ by a few percent. The method is what matters, not the last digit.

The naive way people read this

The rule of thumb goes: “gold roughly tripled over these eight years, so all three - SGB, ETF, physical - made you the same money. The 2.5% coupon is loose change.” It sounds reasonable, and it is wrong on both counts. The three instruments did not return the same, and the coupon plus the tax break is precisely the gap between them. Let us show where the rule of thumb breaks.

Step 1: The price appreciation everyone gets

Gold went from Rs 3,114 to roughly Rs 9,000 per gram over the eight years. That is a 2.89x on the metal, a price-only CAGR of about 14.2%. This part is identical for the SGB holder, the ETF holder, and the coin holder, because all three track the same domestic gold price. On 100 grams:

Redemption value  = 100 x Rs 9,000   = Rs 9,00,000
Cost              = 100 x Rs 3,114   = Rs 3,11,400
Gross price gain                     = Rs 5,88,600

If the story stopped here, all three instruments would be a wash. It does not stop here.

Step 2: The coupon the SGB paid along the way

The SGB paid 2.5% per year on the issue price, not on the current market value. That is a fixed Rs 77.85 per gram per year, Rs 38.93 every six months. Over eight years and 16 payments:

Coupon per gram over 8 years = Rs 77.85 x 8 = Rs 622.80
On 100 grams                                = Rs 62,280 (gross)

This is real cash that hit the bank account twice a year, not a paper number. It is taxable at your income slab. For a 30% bracket investor, the after-tax coupon is Rs 62,280 x 0.70 = Rs 43,596. A gold ETF and a gold coin pay nothing here. Zero.

Note the common misconception buried in this line: only the capital gain on an SGB is tax-free at maturity. The coupon is fully taxable every year. Plenty of holders forget to declare it. Do not be one of them.

Step 3: The tax bill at the finish line

This is where the instruments split apart hard.

SGB held to maturity: capital gains on redemption are entirely exempt. The full Rs 5,88,600 gain is yours. Tax on the gain: Rs 0.

Gold ETF: no coupon, plus a Total Expense Ratio (TER) of roughly 0.5% a year quietly eats the NAV. Over eight years that drag compounds to about 4%, so the same gold exposure is worth around Rs 8,64,540 instead of Rs 9,00,000. When you sell in 2026, the gain is taxed as LTCG at 12.5% without indexation (the regime in force after the July 2024 Budget for gains realised now).

ETF gross value    = Rs 9,00,000 x 0.9606 (8 yrs of 0.5% TER) = Rs 8,64,540
ETF capital gain   = Rs 8,64,540 - Rs 3,11,400               = Rs 5,53,140
LTCG at 12.5%                                                 = Rs 69,143
ETF net in hand    = Rs 8,64,540 - Rs 69,143                 = Rs 7,95,397

Physical gold (coins/bars): you paid a premium and 3% GST going in, so the same Rs 3,11,400 budget bought fewer grams (roughly 92-93g after an ~8% all-in markup). You lose another ~2% to the dealer’s buy-back spread on exit, pay the same 12.5% LTCG, and carry a locker cost of ~Rs 2,000 a year. Jewellery is worse still, because 10-25% making charges vanish the moment you buy.

Step 4: What each holder actually kept

Per 100 grams, Rs 3,11,400 invested in May 2018, redeemed/sold in May 2026:

The SGB holder walked away with Rs 9,43,596. The ETF holder, who tracked the exact same gold price, kept Rs 7,95,397. That is a gap of Rs 1,48,199 on a Rs 3.11 lakh investment - the SGB delivered roughly 47% more profit for identical gold exposure.

Where did that Rs 1.48 lakh edge come from?

This is the part the rule of thumb misses entirely. The gap is not luck; it is three specific, repeatable line items:

So the “loose change” coupon alone was Rs 43,596 of hard cash, and the tax-plus-cost saving was another Rs 1.04 lakh. Neither is small. Together they are nearly half the original outlay.

The XIRR nuance, because coupons arrived early

The 14.9% figure above is the simple CAGR on the final corpus. But the SGB coupon was paid twice a year, so that cash was in your hands early and could be redeployed. On a proper XIRR basis - treating each Rs 3,892.50 semi-annual coupon as an interim inflow and the Rs 9,00,000 as the terminal inflow - the pre-tax return works out closer to ~15%, and the post-tax XIRR to roughly 14.6-14.9%. The ETF has no interim cash flow, so its XIRR and CAGR are the same ~12.4%. Early cash is worth more than late cash, and only one of these instruments paid you early.

Three things holders got wrong

Selling on the exchange before maturity. SGBs list on the NSE/BSE, and some 2018 holders sold there in 2024-25 to book gains. The moment you sell on the exchange instead of redeeming at maturity, you lose the tax exemption - that gain is taxed at 12.5% LTCG, exactly like the ETF. Worse, SGB secondary-market liquidity is thin and units often trade at a 1-3% discount to fair value, so you take a haircut on the way out too. Holding the full eight years is not a technicality; it is the entire tax case.

Ignoring the coupon at tax time. The Rs 62,280 of interest over eight years is taxable each year under “income from other sources.” It does not show up in your capital gains statement, so it is easy to miss and easy for the department to flag later.

Assuming the redemption price equals the spot on maturity day. It is the three-day IBJA average. If gold spikes 4% the morning your bond matures, you do not fully capture it. Over eight years this rounds out, but do not expect the exact screen price.

Would a fresh SGB do this again?

Probably not on the same terms, and this matters for what you do next. The RBI has effectively stopped issuing new SGB tranches since the gold run-up made them expensive for the government to service. So you cannot buy a fresh 2.5% bond at issue today. Your only routes to SGB exposure now are the secondary market (thin, often at a premium to fair value, and any pre-maturity sale is taxed), or waiting for issuance to resume, which is not guaranteed. For new gold allocation in 2026, a low-TER gold ETF is the practical default, and you accept the ~2 percentage point annual tax-and-coupon disadvantage that this whole post just quantified.

Bottom line

If you held SGB 2018-19 Series I to maturity, you did the single best thing available in Indian gold: you captured the full ~2.89x price move, pocketed roughly Rs 62,000 of coupon per 100 grams along the way, and paid zero tax on the capital gain. That combination beat an identical gold ETF position by about Rs 1.48 lakh per 100 grams, or roughly 2.5 percentage points of CAGR a year, for taking on nothing but eight years of illiquidity. What to actually do now: if you still hold a 2026-maturing tranche, redeem it at maturity rather than dumping it on the exchange, and declare the coupon. If you are building fresh gold exposure, you have lost the SGB window for now, so use a direct-plan gold ETF, keep gold to 8-12% of the portfolio, and do not overpay for physical unless you specifically want metal in hand.
