The dated date is the date when interest begins to accrue on a bond, which is often the same as the date of issuance or issue date. On the final settlement date, bond issuers must pay bondholders the accrued interest in addition to the face value of the bond.
For example, an investor might buy a bond with a dated date of September 15, 2023 and a settlement date of September 15, 2033. In this case, the bond would begin paying or accruing interest on September 15, 2023 with the full interest and face value due in 2033.
