Ten days. That’s how long it took, after the Senate blocked the Clarity Act, for two of the crypto industry’s most prominent figures in Washington to post their exit dates. Neither one mentioned the bill.
On Friday, Blockchain Association CEO Summer Mersinger and SEC Commissioner Hester Peirce made their departures public. Mersinger steps down Oct. 16. Peirce leaves Oct. 2.
The timing is hard to ignore, even if both statements are silent on it. The Clarity Act was the market structure bill the industry had spent years pursuing. Now the lobbying group’s chief and the regulator who ran the SEC’s crypto effort are both on their way out.
The SEC gets thin
Peirce’s move is the one with bigger structural consequences. When she goes, the SEC will be down to two commissioners, Chairman Paul Atkins and Mark Uyeda, according to the agency’s roster.
Her exit itself wasn’t a surprise. Regent University’s law school said in May that she would join its faculty in November. What Friday added was a date: her resignation letter to President Trump sets her last day as Oct. 2.
Peirce has been an SEC commissioner since 2018 and was picked to lead the agency’s Crypto Task Force. In her letter, she described giving people the freedom to choose within “sensible regulatory parameters” as a “delicate and vitally important task for the regulator.”
A familiar face returns at the Blockchain Association
Mersinger won’t vanish right away. She’ll stay on as an advisor through the end of the year, the trade group said.
Her replacement isn’t new to the job. Kristin Smith, who joined as the group’s first hire in 2018 and ran it until 2025, will return as interim CEO on Oct. 17. Smith is currently president of the association’s board.
Mersinger, a former CFTC commissioner, took the job in June 2025. Her tenure was short, but the group credits her with steering its work on the GENIUS Act, the stablecoin law President Trump signed in July 2025. It also points to regulatory steps such as the joint SEC-CFTC interpretation that most crypto assets are not themselves securities.
“I came here from the CFTC because I believed this industry deserved clear rules of the road and a credible, unified voice making the case for them in Washington,” Mersinger said in the release.
That pitch reads differently now that the rules of the road the industry wanted most just stalled in the Senate.
Circle’s shake-up lands the same day
The exits weren’t limited to Washington. Stablecoin issuer Circle said Friday that CFO Jeremy Fox-Geen will step down by the end of December, after more than five years that included the company’s $1.2 billion IPO.
Co-founder P. Sean Neville also resigned from Circle’s board, effective immediately, for personal reasons, the company said in a securities filing.
If you’re tracking who speaks for crypto in Washington, mark Oct. 2 and Oct. 16. After those dates, the SEC runs on two commissioners and the industry’s main trade group runs on an interim chief, with the bill they were both working around still blocked.
