Date of Issue
The date, on which a particular financial asset is issued, is termed as the date of issue. In the context of bonds, the date of issue is the date on which the bond is issued, and interest begins to accrue on the bondholder. On the other hand, the date of issue in the context of stocks, is the date on which trading begins on a fresh stock issued to the public.
In addition, insurance companies also use the date of issue to refer to the date on which the policy is issued, which can vary from the date on which the policy will become effective.
