Citadel Securities Warns SEC That Private Rooms, 24-Hour Trading Are Emerging Risks

Citadel Securities is urging the Securities and Exchange Commission’s new leadership to examine a list of what it argues are emerging and mounting risks, including opaque trading in so-called private rooms and the push by US stock markets to operate around the clock.

Billionaire Ken Griffin’s market-making firm sent more than 30 recommendations, spotlighting concerns in equities, credit, treasuries, options and digital assets. Subjects included private rooms — a twist on dark pools, in which only certain parties are allowed to transact.

“Now is the right time to comprehensively review the current regulatory framework and take decisive action to remove unnecessary costs and increase efficiency to unleash a new wave of innovation,” the firm wrote in a document sent to the commission and reviewed by Bloomberg.

Though Citadel Securities is often vocal about how it thinks the agency should handle market structure — an issue key to the firm’s own operations and profits — its input may reach more a receptive audience as President Donald Trump’s administration installs new leaders at the SEC. A representative for the watchdog declined to comment.

The latest round of recommendations comes just days after Paul Atkins was sworn in as SEC chairman. Atkins is expected to scale back regulation, ease disclosure requirements and adopt a friendlier stance for certain companies that once sparred with his predecessor, Gary Gensler.
