The Securities and Exchange Commission has amended its quorum rule to allow a single commissioner to act for the entire agency in narrow circumstances, specifically when every other sitting commissioner is disqualified due to ethics rules or a conflict of interest.
The SEC adopted the amendment on September 30, 2026, under Release No. 34-106537, with an effective date of October 2, 2026. Under standard procedure, a quorum at the SEC requires three commissioners. The new exception permits one eligible commissioner to count as a quorum if all other sitting members face disqualifications on a particular matter.
This represents an expansion of earlier guidance dating back to 1995, which allowed two commissioners to act when disqualifications reduced the available pool. The agency framed the amendment as a practical measure to maintain operations when vacancies or disqualifications would otherwise limit its capacity to make decisions.
The timing coincides with significant staffing changes at the agency. Commissioner Hester Peirce's leave of absence took effect on October 2, 2026, the same day the rule became effective. This leaves Chair Paul Atkins and Commissioner Mark Uyeda as the only two active commissioners, with the SEC maintaining five authorized seats.
The amendment has drawn mixed reactions. Critics raised concerns about consolidated decision-making, noting that substantial agency actions could rest with a single member. Supporters argue it is a necessary operational adjustment that does not expand the SEC's substantive powers or sidestep judicial oversight.
Several crypto-related proposals are currently pending at the SEC. A proposal on crypto-asset custody, covering how digital assets are held and safeguarded, has a public comment deadline of December 7, 2026. A second proposal on an offering exemption under Regulation Crypto Assets has a comment deadline of October 20, 2026.
As of mid-October 2026, no decisions had been recorded under the new quorum provisions. The amendment applies to any matter where all other sitting commissioners are disqualified, regardless of whether the issue involves digital assets, equities, enforcement, or other SEC responsibilities.
Rules finalized by a single commissioner may face greater scrutiny regarding legitimacy compared to decisions backed by a full, bipartisan commission. Future developments to watch include the October 20 and December 7 comment deadlines, whether the single-commissioner exception is actually invoked and on what matters, and any new commissioner appointments that could alter the agency's composition.
