RBI dropped the issuance calendar for Government of India dated securities. Rs 8,20,000 crore total borrowing across 26 auction weeks from April to September 2026.

a few things worth flagging for retail investors:

this week (April 6 to 10) is a 10-year G-Sec auction for Rs 34,000 crore. next week (April 13 to 17) is 5-year for Rs 21,000 crore and 40-year for Rs 11,000 crore. the 30-year Sovereign Green Bond (SGrB) shows up in weeks 4, 12, and 20.

you can bid directly via RBI Retail Direct. the bidding window opens each auction week.

does anyone here actually participate in these primary auctions or is everyone buying from the secondary market?

secondary market only
primary auction cut-off is unpredictable

wait there’s actually a calendar for this? i always assumed you just buy whenever on retail direct
didn’t know there were specific auction weeks

Yes, the government borrows through weekly auctions on a pre-announced schedule. The RBI releases this calendar at the start of each financial year. Each auction week has specific tenures and amounts. Retail investors can participate through RBI Retail Direct by submitting non-competitive bids, which means you get the weighted average cut-off price determined by institutional bidders without needing to specify a yield.

non-competitive bid is the key thing for retail
you don’t fight institutions on price
just apply and get allotted at whatever the auction clears at

but if I buy from secondary market on BondScanner I can see the yield upfront and decide. in a primary auction I don’t know what yield I’ll get until after. isn’t secondary market actually better for retail?

7

what is the SGrB that keeps showing up in the calendar? is that different from a regular G-Sec?

Sovereign Green Bond. Issued by the Government of India specifically to fund green projects like renewable energy and clean transport. The sovereign guarantee is identical to a regular G-Sec so the credit risk is the same. The difference is that the proceeds are ring-fenced for environmentally designated projects. Some investors prefer them for ESG reasons. The yield is typically similar to or slightly below equivalent tenure G-Secs.

I have participated in a few primary auctions via Retail Direct over the years. The process is straightforward but you do need patience. Allotment takes a day or two after the auction closes. The non-competitive bid route is fine for retail but if you want a specific yield you are better off on the secondary market where you can see it before you buy.

summary:

primary auction = fresh issue, market price, weekly windows, apply blind on yield
secondary market = buy any time, see yield upfront, more flexibility
sgrb = same as g-sec but proceeds go to green projects, sovereign guaranteed
