SEC Commissioner Hester Peirce has submitted her formal resignation from the US Securities and Exchange Commission, effective Oct. 2.
Peirce, also known as “Crypto Mom” amid her advocacy of clear, rules-based regulation of the crypto industry, posted a copy of her resignation letter on her X account Friday.
In the letter, she thanked the president for the “honor of her professional lifetime” serving as a commissioner and said she was leaving the SEC under the excellent leadership of Chairman Paul Atkins and Commissioner Mark Uyeda, the two remaining members, who are both Republicans.
Peirce served on the commission for about eight years. Since Feb. 4, 2025, she was also director of the agency’s Crypto Task Force. Her term at the SEC officially expired in June 2025, but commissioners “may continue to serve up to approximately 18 months after terms expire if they are not replaced before then,” according to the agency.
