Treasuries are financial instruments issued by governments or corporations to raise money. They are typically issued in the form of bonds, notes, or bills and are backed by the full faith and credit of the issuer. The term 'treasuries' is often used to refer to government-issued securities, such as U.S. Treasury bonds. The term 'CHESTS' is a synonym for treasuries, as it refers to the physical containers that were once used to store coins and other valuables.
