Peirce defends crypto privacy tools against the surveillance push

SEC Commissioner @HesterPeirce, who leads the regulator's Crypto Task Force, used a speech at Georgetown University Law Center on Wednesday to push back against what she described as a creeping surveillance bias in US financial regulation, arguing that cryptographic privacy tools are too often treated as instruments of crime rather than legitimate protections for individuals.

Privacy as a principle, not a loophole

Peirce delivered her remarks at Georgetown Law's "Regulating the PETshop" seminar series, calling for the integration of privacy-enhancing technologies (PETs) into the financial regulatory framework. Her argument was straightforward: the balance between security and individual liberty has tipped too far toward the state. "Empowering government to be able to identify, pursue, and punish the bad guys is important to the security of the nation and its people, but so too is empowering people to protect information about their lives, including their financial lives," she said. She added that privacy technologies should not be viewed as "an opportunity for the government to watch more of what its citizens do."

She criticized the current regulatory orientation for overly favoring government surveillance, arguing that technology should serve to protect individual privacy rather than expand surveillance capabilities. Peirce has previously made a case for modernizing the Bank Secrecy Act and the third-party doctrine, which allows the government to obtain financial information without a warrant.

A call to engage, not retreat

Rather than drawing a line in the sand, Peirce framed her remarks as an invitation. She invited technology teams capable of minimizing personal information collection, while still meeting KYC and anti-money laundering (AML) regulatory requirements, to proactively collaborate with the SEC's Crypto Task Force. She also noted that blockchain public wallet addresses can reduce the risk of investor personal information leakage while still satisfying compliance requirements.

Privacy coins and protocols sit at the center of that debate. Projects such as Monero and Zcash have long faced regulatory skepticism because of their anonymity features, with compliance teams at exchanges frequently flagging them as elevated-risk assets. Global regulators are signaling deeper scrutiny of DeFi, privacy-enhancing technologies, and cross-border transactions as enforcement activity intensifies across jurisdictions. Peirce's position offers a counterweight, one that carries institutional weight given her role at the SEC.

The SEC's Crypto Task Force, led by Commissioner Peirce and established in January 2025, aims to develop a comprehensive regulatory framework through public and industry engagement. Wednesday's speech signals that the privacy question will remain a live issue within that process, and that developers of privacy-preserving tools have a direct line to the regulator if they choose to use it.
