About Mortgage-Backed Securities (MBS) Trade Activity

This data provides comprehensive information on mortgage-backed securities (MBSs) that traded within the past 10 years. Access up to three years real-time trade history and seven years end-of-day trade history per security. Trade history represents mortgage securities with similar characteristics, i.e., reference data ID (RDID). An MBS provides issuers with monthly payments from a pool of mortgages and passes on a proportionate share of the collected principal and interest to bondholders. Learn more about MBSs and other bond types.

Data PurposeComprehensive MBS information is published for non-commerical use to create level playing field for all market participants.
