WASHINGTON — The SEC’s proposed best interest rule is poised to change how advisors operate, and maybe FINRA too.
“If [Regulation Best Interest] is adopted, then we would need to look at our rule set to see if any changes are appropriate,” FINRA CEO Robert Cook told attendees at SIFMA’s annual conference. “For example, is our suitability rule appropriate?

“We worked very hard on making sure the SEC took up a best interest standard, and we’ve seen that come closer to fruition,” SIFMA Chairwoman and Charles Schwab executive vice president Lisa Kidd-Hunt told attendees. “That is something we’ve long supported as an industry.”
