BWIC Data Standard

The Bids Wanted in Competition (BWIC) data set provides the ability to automate the bidding process for Mortgage-Backed Securities (MBS) between mortgage originators and dealers.

Mortgage originators are choosing MBS execution more than ever before and are distributing BWICs, a formal request for bids on a package of securities, to securities dealer desks. Currently, the information transmitted to dealers is not standardized; as a result, dealers are having trouble keeping up with the increased volume of BWICs, which can lead to delays, lower pricing, and less participation in the BWIC than desired. 

Creation of this data standard, based on the MISMO BWIC template, will allow the downstream trade desks to apply automation to accelerate and enhance the accuracy of trade execution helping to increase the BWICs processed.
