U.S. Securities and Exchange Commission Commissioner Hester Peirce will leave the agency on Oct. 2, ending a long run in which she pressed for clearer crypto rules from inside a regulator that often chose enforcement over bespoke digital-asset policy.
Peirce, known across the industry as "Crypto Mom," disclosed the date in a resignation letter posted Friday on X. Her exit was announced as the SEC released another piece of crypto policy guidance aimed at clarifying how the agency defines tokens and what it expects from projects when they market those tokens.
For years, Peirce stood out as one of crypto’s steadiest allies at the SEC. She argued for clear rules during the tenures of Republican Chair Jay Clayton and Democratic Chair Gary Gensler, even as both periods were marked by aggressive crypto enforcement and little appetite for a dedicated regulatory framework for the sector.
She did not get a real chance to work on rules until President Donald Trump’s administration. Before current Chair Paul Atkins arrived, Peirce had already been placed in charge of the SEC’s new Crypto Task Force last year.
Policy work across mining, staking and asset definitions
Peirce’s crypto portfolio covered a broad range of topics. The SEC issued policy statements and guidance during her watch on mining, staking, memecoins and, crucially, definitions used to sort crypto assets into categories and identify which regulator has jurisdiction.
More recently, the agency moved into formal rule proposals. That included a framework called Regulation Crypto Assets, which set out a way to offer crypto assets without automatically triggering the toughest securities requirements.
One of the agency’s most prominent recent moves was opening a path for tokenized securities. The initiative, called the "innovation exemption," uses a limited five-year approach intended to start the tokenized-securities era while giving the SEC material to shape more permanent rules later.
In her resignation letter, Peirce wrote: "Maximizing people’s freedom to choose what is best for themselves and their families within sensible regulatory parameters designed to give them the confidence to transact with others is a delicate and vitally important task for the regulator."
She is set to become an associate professor at Regent University School of Law.
"Crypto Mom" and her earlier criticism of the SEC
Peirce publicly embraced the "Crypto Mom" label in a 2019 speech, delivered during a period when the agency was broadly resistant to the industry. In that speech, she said the SEC had "hindered innovation and growth," adding: "The only guidance out of the SEC is a parade of enforcement actions and a set of staff guidance documents and staff no-action letters."
Commission reduced to two members
Her departure will leave the SEC with only two commissioners: Atkins and Republican appointee Mark Uyeda. Under agency rules, two members can serve as a quorum when the commission is short-handed.
So far, Trump’s White House has not named Democratic nominees to either the SEC or the Commodity Futures Trading Commission. It remains unclear whether Trump will now move to fill those vacancies.
SEC released more crypto FAQs the same day
On Friday, the agency added to Peirce’s crypto record with more work on defining crypto assets and explaining how a project’s managerial expectations fit into those classifications. The SEC issued a frequently asked questions document addressing several points.
Among them, staff said the industry had asked how token marketing, software changes or other project actions can avoid triggering analysis around "essential managerial efforts."
The technical FAQ also addressed "staking receipt tokens" and when a secondary market may be treated as a "promoter" of an investment contract.
