How to Buy Government Bonds (G-secs) in India: All 4 Routes Compared
Buying a Government of India bond is now easier than opening most fixed deposits. There are four distinct routes, though, and the wrong one costs you either money (spreads and fees) or flexibility (liquidity, consolidation). Here’s the map.
First, decode the name
G-secs have names like “7.10 GS 2034”, meaning a bond paying a 7.10% annual coupon in two semi-annual instalments of 3.55%, maturing in 2034. Face value is ₹100, interest accrues on the 30/360 convention, coupons arrive every six months with no TDS for resident individuals, and the credit is the Government of India. Tenors run from 1 to 40 years, so “G-sec” covers everything from cash management to a retirement-length lock.
Route 1: RBI Retail Direct auctions
The default choice. The RBI auctions G-secs most Fridays, with T-bills on Wednesdays and SDLs usually on Tuesdays. On RBI Retail Direct you bid non-competitively: enter an amount from ₹10,000 and you’re allotted at the auction’s weighted-average price. The mechanism makes overpaying impossible.
- Open the free RDG account. PAN plus Aadhaar e-KYC, about 15 minutes.
- Go to Primary Market and pick the security from the auction calendar. New issues and re-issues of existing bonds both appear, with coupon and maturity shown.
- Enter the amount and pay by UPI or net banking. The allotment price is confirmed after the auction and excess funds come back.
- Coupons and redemption land in your bank account automatically.
Cost: zero. This route wins for anyone buying to hold, which should be most readers. Plan multi-maturity purchases in the ladder builder.
Route 2: NDS-OM Retail, the secondary market
The same Retail Direct login gives you NDS-OM Retail, where existing G-secs trade. Use it when you want a specific maturity today rather than waiting for an auction, or for odd tenors that rarely get re-issued.
Quotes are clean prices per ₹100, with accrued interest added at settlement. Run any quote through the YTM calculator to see the real yield, and the accrued interest calculator to predict the exact debit. Liquidity is good in benchmark issues and patchy elsewhere, so use limit orders and be willing to wait.
Route 3: Your stockbroker
Zerodha, Groww, ICICI Direct and others route auction bids through NSE goBID or BSE Direct, and some list gilts for secondary trading, with holdings sitting in your regular demat account.
What you gain is one app, one portfolio view, familiar mechanics, and in some cases holdings you can pledge. What you give up is a small fee or spread, a narrower inventory than Retail Direct, and auction access that’s sometimes limited to selected securities. It’s a reasonable route if consolidation matters more to you than the last few basis points.
Route 4: Gilt and target-maturity funds
Funds hold the G-secs for you, which buys instant liquidity, tiny ticket sizes and no admin. The costs are an expense ratio and, more importantly, no fixed maturity value at all in open-ended gilt funds, or an approximate one in target-maturity funds. Post-2023 rules also tax all debt-fund gains at slab, while a directly held G-sec bought below par converts part of its return into 12.5% LTCG. For goal-dated money, holding directly wins. For open-ended allocation, funds are fine.
Which route, when
| You want | Route |
|---|---|
| Maximum yield, hold to maturity, zero cost | Retail Direct auctions |
| A specific maturity, today | NDS-OM Retail (check the quote’s YTM) |
| Everything inside one broker app | Broker / goBID |
| Liquidity above all | Gilt or liquid funds |
| Yearly cash for spending goals | Ladder via Retail Direct |
Practical wisdom
Buy re-issues of benchmark bonds if you might need to sell early, because that’s where liquidity concentrates.
Don’t avoid long tenors, but do size them. A 30-year G-sec locks a rate for a generation and swings hard with yields, so check the damage in the duration calculator before committing.
SDLs use the same workflow, and lately for a good deal more extra yield than the 25–40 bps they used to pay: July 2026 auctions came in around 65–80 bps over comparable G-secs. The SDL guide covers the credit question.
Compare auction yields against FDs on a post-tax basis rather than a pre-tax one. The FD vs bond calculator settles it in seconds.
FAQ
What’s the minimum investment? ₹10,000 at auction through Retail Direct, or one unit of ₹100 face on the secondary market, though very small lots can struggle to trade.
When do I get my first coupon? On the bond’s next scheduled coupon date. You’ll have paid accrued interest at purchase, and that first coupon returns it to you.
Can G-secs lose money? Not in nominal terms if you hold to maturity. Marked to market or sold early, yes, and that’s duration risk rather than credit risk.
Auction or secondary, which gets better prices? Auctions usually, for whatever is being auctioned that week. Secondary wins when you need a maturity the calendar isn’t offering.
