The U.S. Securities and Exchange Commission’s volume rulemaking is “problematic” because regulatory agencies should act gradually and deliberately, SEC Commissioner Hester Peirce said Thursday.

“It is understandable that a chairman of the agency has a lot of ambitions about what kinds of things should change and how those changes should happen,” Peirce said at the Security Traders Association’s annual conference in Washington, D.C. “But if you want to do things right in a regulatory agency like ours, I really think you have to be gradual in how you do things and you have to really be deliberate and get a lot of input.”
