One SEC commissioner is pushing for a comprehensive review of the structure and regulatory regime of United States financial markets, including SROs.

The SEC is serious about looking comprehensively at market structure issues, and must be willing to review its existing rules to see their impact on market structure.  One item is the regulatory framework concerning the status of SROs, given the proliferation of dark pools and alternative trading venues.

In short, the SEC will examine market structure to see if changes are necessary.
