The Reserve Bank of India (RBI) conducts auctions of Treasury bills at 91-, 182-, and 365-day tenors. Data Buffet carries the implicit yield at cut-off price, which is the yield on an instrument if it is held to maturity.

Global concept aliases:
Treasury bills or T-bills, which are money market instruments, are short term debt instruments issued by the Government of India and are presently issued in three tenors, namely, 91 day, 182 day and 364 day. Treasury bills are zero coupon securities and pay no interest. They are issued at a discount and redeemed at the face value at maturity. For example, a 91 day Treasury bill of Rs.100/- (face value) may be issued at say Rs. 98.20, that is, at a discount of say, Rs.1.80 and would be redeemed at the face value of Rs.100/-. The return to the investors is the difference between the maturity value or the face value (that is Rs.100) and the issue price.
A yield based auction is generally conducted when a new Government security is issued. Investors bid in yield terms up to two decimal places (for example, 8.19 per cent, 8.20 per cent, etc.). Bids are arranged in ascending order and the cut-off yield is arrived at the yield corresponding to the notified amount of the auction. The cut-off yield is taken as the coupon rate for the security. Successful bidders are those who have bid at or below the cut-off yield. Bids which are higher than the cut-off yield are rejected.
Timeliness
The 91-day bills are issued weekly while the 182-day and 364-day bills are issued bi-weekly.
Since January 2013, the R.B.I. has stopped publishing the auction yields in its Weekly Statistical Bulletin but will instead published them in the Monthly Statistical Bulletin.
Long-term sovereign debt is traditionally considered to have a tenor of around 10 years. Since the Government of India issues only shortt-erm debt instruments, we have assigned the global concept alias IRGTLT to the 364-day T-bill.
