SEC Commissioner Mark Uyeda defends quorum rule revisions

The Securities and Exchange Commission is down to two commissioners. One of them now says that’s no reason to panic.

On October 12, 2026, SEC Commissioner Mark T. Uyeda wrote a letter to the Financial Times defending recent changes to the agency’s quorum rule. His core argument is that the SEC’s mission has not changed, even though the commission looks noticeably emptier than it did a few weeks ago.

Commissioner Hester Peirce has departed, and the agency is now operating with two members while three seats sit vacant.

What the rule change actually does

The SEC adopted the amendments on September 30, 2026. They took effect on October 2, the same date the commission dropped to two members.

The revision addresses a specific scenario. If the other sitting commissioners are disqualified from a matter because of ethics rules or conflicts of interest, a single eligible commissioner can now establish a quorum on that matter.

Uyeda framed the change as an operational fix, not a philosophical shift. In his letter, he argued that the amendments preserve how the agency already worked while spelling out more clearly how quorum is handled in edge cases.

Why critics have something to chew on

The amendments were enacted without a notice-and-comment period. The SEC classified the change as an internal management matter, which exempts it from the usual process of public feedback.

The rule was adopted on September 30, became effective on October 2, and the commission was reduced to two members as of that same day.

Uyeda also has history on his side, at least partially. The SEC has operated with fewer than three commissioners before, including during the Clinton administration.

Background: a commission running lean

The SEC is structured as a five-member bipartisan commission, a structure in place since its inception in 1934, with a quorum of three members to ensure collaborative decision-making. With three of five seats vacant, that structure is under strain.

The SEC’s prior quorum rules already allowed actions by the number of commissioners in office when fewer than three were serving, and permitted two eligible members to act when recusals brought participation down to two. The new amendments extend this further, allowing a single commissioner to act when all others are disqualified.

What this means for markets and regulation

The change could open the door to more agile decision-making on pending proposals affecting digital assets, including those tied to custody and operational rules. Custody rules govern how firms hold assets on behalf of clients, which makes them a significant concern for exchanges, fund managers, and anyone offering crypto products.

Decisions made by a single eligible commissioner, under a rule adopted without public comment, may be more exposed to legal challenges from parties who dislike the result. Whether that risk materializes depends on how often the provision is actually used and on what kinds of matters.

The bigger variable is the vacancies themselves. Three open seats is a lot, and the quorum rule only matters this much because the commission is so thinly staffed. If those seats get filled, the single-commissioner scenario becomes a rare edge case again.
