Treasury bills are short-term, marketable debt obligations issued by the U.S. Treasury to finance government operations. Treasury bills, also known as T-bills, have maturities of one year or less and are considered very safe investments because they are backed by the full faith and credit of the U.S. government.
Treasury bills are an important part of the U.S. financial system and play a vital role in financing the government’s short-term borrowing needs. They are also used by investors to manage their cash flow and to diversify their portfolios.
