A bond auction is the primary market process through which the government or a corporate issuer sells newly issued bonds to investors through a competitive bidding mechanism. In India, the Reserve Bank of India conducts regular auctions of government securities (G-Secs and T-Bills) on behalf of the Central Government, typically through a uniform price or multiple price auction format. Primary dealers are obligated to participate and underwrite a minimum quantum in each auction. Successful bidders receive allotment at the cut-off yield determined by the auction. The auction process enables transparent, market-determined pricing of government debt and helps establish the benchmark yield curve for the Indian fixed-income market.
