Government debt is a separate world with its own plumbing. The Reserve Bank of India issues and services central government paper, and its Public Debt Office acts as registry and depository. Treasury bills are zero coupon instruments issued at a discount in three tenors, 91 day, 182 day and 364 day. Cash Management Bills, introduced in 2010 with the first set issued on May 12, 2010, cover temporary cash mismatches at tenors shorter than 91 days. Dated securities generally run from 5 years to 40 years and pay a coupon half yearly; state governments issue only dated paper, called State Development Loans.
Auctions take competitive bids from banks, primary dealers, mutual funds and insurers, with a minimum bid of Rs 10,000 and multiples of Rs 10,000. Retail buyers bid on a non competitive basis through an aggregator, capped at a maximum of five percent of the aggregate nominal amount within the notified amount, and no more than Rupees Two crore per security per auction. Secondary trading runs on the anonymous order matching system NDS OM, which matches on price and time priority and carries separate screens for central paper, state loans and bills.
