NYSE Bonds System The NYSE Bonds System replaced the NYSE Automated Bond System (ABS) in April 2007 and now provides a more efficient and transparent way to trade corporate, agency and government debt securities. The platform is based on the design of NYSE Arca’s comprehensive matching technology allowing NYSE Members to enter orders to buy or sell bonds electronically. The system has also been expanded to include the corporate debt of all NYSE-listed securities and their wholly-owned subsidiaries; making NYSE Bonds the largest centralized corporate bond market in the U.S.
