Treasury Bills (T-Bills) are short-term money market instruments, issued by the Central Government through the Reserve Bank of India (RBI) for 91, 182, or 364 days.
T-Bills are auctioned weekly by the RBI on behalf of the government, with the notified amount for each tenure published in advance via a quarterly auction calendar.
The 91-day auctions were oversubscribed by over three times the specified amount, as of 4 March 2026, demonstrating strong investor participation.
The treasury bill rates, which are determined by the RBI monetary policy and system liquidity, indicate the overall short-term borrowing costs in the economy.
T-Bills are issued at a discount and redeemed at par or face value. The difference acts as a return to investors.
