On this page, we explain the current pattern for auctioning the five main types of Treasury marketable securities, organized by type of security.
These pages give you different views of the auction schedule:
Various situations, such as Treasury's needs, policy decisions, and Congressional action on the debt limit may change these patterns.
Holidays and special circ*mstances may also disrupt the schedule. If the day the securities should be issued is a weekend or federal holiday, we issue the securities on the next business day.
All securities, except bills, start earning interest on the Issue Date or Dated Date, whichever comes first. That is, the security accrues interest. We add this accrued interest to your purchase price of the security. You get the accrued interest payment back with your first regular interest payment for that security.
