The Division is considering recommending that the Commission adopt amendments to Regulation SCI that would expand its application to additional key market entities and update certain of its provisions to take account of the evolution of technology and trading since the rule’s adoption in 2014. The proposed expansion would add the following entities to the definition of "SCI entity": registered security-based swap data repositories; registered broker-dealers exceeding an asset or transaction activity threshold; and additional clearing agencies exempted from registration. The proposed updates would amend provisions of Regulation SCI relating to: (i) systems classification and lifecycle management; (ii) third party/vendor management; (iii) cybersecurity; (iv) the SCI review; (v) the role of current SCI industry standards; and (vi) recordkeeping and related matters. Further, the Commission requested comment on whether significant-volume ATSs and/or broker-dealers using electronic or automated systems for trading of corporate debt securities or municipal securities should be subject to Regulation SCI.
