SGB (RBI's Headache in 2027)

SGBs: A Windfall

With Hidden Costs

Sovereign Gold Bonds (SGBs) were launched as a clever idea. The government wanted households to shift from physical gold to a paper form, while also raising funds in the process.

The product looked simple and safe. It was backed by the government, linked to gold prices, and paid a fixed 2.5% annual interest. The bonds had an 8-year maturity, with an exit option after 5 years.

However, a key feature changed the story. The bonds were linked to the market price of gold at redemption. As gold prices surged, early SGB investors earned extraordinary returns. This upside for investors now creates a potential fiscal challenge for the government.

How Early Investors

Gained So Much

Consider one example. The SGB 2018–19 Series III was issued at 3,133 rupees per gram. Its premature redemption price on 13 May 2026 was 15,102 rupees per gram. That implies a return of about 382%. Other tranches have shown absolute returns of 200% to nearly 400%.

Data from recent redemptions illustrate this pattern. For example, the SGB 2017–18 Series XIV matured on 1 January 2026. Its issue price was 2,890 rupees per gram, while the redemption price was 13,486 rupees per gram. That is a gain of about 367%. Similar outcomes appear in multiple 2019–2021 tranches, with gains around 200–280% or more.

In simple terms, gold’s rally has turned what was meant to be a conservative savings product into an equity-like jackpot.

Why Investors

Are Not Exiting

One might expect investors to rush for the exit and book these huge profits. Yet the data show very low early redemption rates. Take the SGB 2020–21 Series XII. It became eligible for premature redemption on 4 May 2026. Out of 32.3 lakh grams subscribed, only about 33,500 grams were redeemed. The exit rate was roughly 1.04%.

There are solid economic reasons for this behaviour. Investors continue to earn the 2.5% annual interest on the face value. Original subscribers also enjoy tax-free capital gains if they hold till maturity. Many investors likely expect gold prices to keep rising in the long run. So they face a classic trade-off: book gains now, or hold on for more potential appreciation plus interest. Most investors, just like me, are choosing to hold.

The Government’s

Growing Liability

From the government’s perspective, the structure looks very different. Between 2015 and 2024, 67 tranches of SGBs were issued, raising 72,275 crore rupees. Of these, 22 tranches have already been redeemed. That leaves 45 tranches outstanding.

At today’s gold prices, the value of these outstanding bonds is about 1.85 lakh crore rupees. This is not a fixed number. It will move with gold prices until redemption. Even under a scenario where gold prices fall 20% from current levels, the government would still repay almost double the amount originally raised. The scheme has therefore transformed into a very expensive form of government borrowing.

Design Risk:

Linking Debt to a

Volatile Asset

Economically, SGBs illustrate the risk of linking public debt to a volatile commodity. When the scheme started in 2015, policymakers likely did not anticipate a nearly 469% surge in domestic gold prices within a decade. The intention was to reduce physical gold imports and mobilize savings, not to offer a highly leveraged bet on bullion at the government’s cost.

The problem is timing. A large cluster of SGB maturities is due between 2028 and 2032. At that time, the government will have to repay investors based on whatever the prevailing gold price is. If gold remains elevated, the effective interest cost of this borrowing will look extremely high compared to plain vanilla government bonds.

My Inference

Lessons for

Future Policy Design

SGBs offer an important policy lesson. Long-term financial products tied to volatile assets can look cheap at launch but become very costly over time. What started as a smart way to discourage physical gold hoarding turned into one of the most expensive borrowing instruments in the government’s toolkit, purely because the underlying asset outperformed expectations.

The broader takeaway is simple. When governments index their liabilities to fast-rising assets, the true fiscal cost often shows up years later. SGBs are still an ongoing experiment. Many tranches will mature in the coming years, and the final bill is not yet known.

This curious case of SGB highlights the importance of stress-testing public schemes under extreme but plausible market scenarios, before they are launched.
