Since FINRA published Notice 15-43, the broker-dealer regulator started collecting transaction reports for U.S. Treasury securities.
Regulatory Notice 18-09, issued Wednesday, updates the criteria to include criteria for designating firms that report a significant volume of transactions in U.S. Treasury securities to TRACE for mandatory BC/DR testing participation.
With respect to Trade Reporting and Compliance Engine, or TRACE, for Treasuries, FINRA states that it "will designate participants that account for at least 5% or more of the average dollar volume over the six-month period immediately preceding designation, provided that the cumulative dollar volume represented by designated firms amounts to at least 50% of all dollar volume in Treasury securities reported to TRACE during the applicable six-month period."
The criteria contained in Notice 15-43, including the criteria for designating TRACE participants that account for specified activity in corporate and agency debt securities and securitized products, remain otherwise unchanged, FINRA said.
The designation process and test-related guidance in Notice 15-43 also remain unchanged, FINRA states, adding that it expects that the designation and test schedule will be similar in 2018 to 2017, with designation occurring in April and the test occurring in October.
