Selling G-Secs, T-Bills, and SDLs in the Primary Market

Can I sell G-Secs, T-Bills, and SDLs in the primary market?

No, selling G-Secs, T-Bills, or SDLs in the primary market isn't an option. The primary market is exclusively for the initial issuance of these securities by the Government of India. Once they're issued, they can be traded solely in the secondary markets.
