Hester Peirce’s last day at the Securities and Exchange Commission (SEC) is Friday, October 2. What she leaves behind is a commission running on two people.
The SEC’s public roster currently lists three sitting members: Chairman Paul Atkins, Peirce, and Mark Uyeda. After Friday it lists two, unless a new commissioner is sworn in first. The White House has not announced a nominee for her seat.
Peirce posted her resignation letter on X last week. She thanked President Donald Trump for the opportunity to serve and called the job the honor of her professional lifetime, writing that she leaves “confident that under the excellent leadership of Chairman Paul Atkins and Commissioner Mark Uyeda, the talented men and women of the Securities and Exchange Commission will continue to achieve that balance” between regulation and individual choice.
Two Members Can Still Act
The Exchange Act contemplates five commissioners, with no more than three from the same political party. The Democratic seats previously held by Caroline Crenshaw and Jaime Lizárraga are vacant. After October 2, the agency has Atkins and Uyeda.
That is enough to function. Under 17 CFR 200.41, a quorum is normally three commissioners, but when fewer than three are in office, the quorum becomes the number then serving. Two members can therefore act.
The constraint is what happens when they do not agree. With only two commissioners, a single recusal leaves one, and a split leaves a matter unresolved. Neither situation is unlawful; both mean that item does not pass.
The party-balance rule still governs new nominations, and Senate Democrats have argued that filling Peirce’s Republican seat without also naming a Democrat would break the alternation custom written into the Exchange Act. That is an argument about confirmations, not about the legality of Friday’s departure.
How Long She Served
Peirce was sworn in on January 11, 2018, during Trump’s first term. Her second five-year term expired on June 5, 2025.
She has served since then in holdover capacity. SEC commissioners “may continue to serve up to approximately 18 months after terms expire if they are not replaced before then,” the agency’s commissioners page says. That window would have run into December 2026, which means she is leaving roughly two months before it lapses rather than being pushed out by it.
She has led the SEC’s Crypto Task Force since early 2025. The industry nicknamed her “Crypto Mom” during the first Trump administration for her dissents against enforcement-first treatment of digital-asset firms. The label is industry slang, not an official title.
In May, Regent University School of Law in Virginia Beach said she would join its faculty in November as an associate professor covering securities regulation, financial markets, digital assets, and public policy. The Crypto Times reported that appointment when the university made it public. Peirce said at the time that her SEC work, including the task force, remained her focus until she left.
What Stays on the Desk
Her final full week as a commissioner was a productive one. It included the September 17 Innovation Exemption for certain tokenized NMS-stock venues and her September 23 SIFMA speech, “Looking for Change in Haystacks,” which The Crypto Times covered. Staff in the Division of Corporation Finance also published crypto-asset FAQs dated September 25.
Those documents stay in force after she leaves. A commissioner’s departure does not by itself withdraw an order, a staff FAQ, or a proposed rule.
The proposed Regulation Crypto Assets package remains in its public comment period. Comment close dates and any later adoption are Commission actions rather than a departing commissioner’s personal file, so they survive her exit as well.
What has not been announced is who runs the Crypto Task Force next. The SEC’s site does not name a successor.
