The time for clear financial privacy rules is now

Despite recent strides in U.S. crypto regulation, particularly between the SEC and CFTC, significant uncertainty persists regarding financial privacy rules. While a Memorandum of Understanding between the SEC and CFTC aims to improve coordination and joint guidance has been issued on applying securities and commodities laws to crypto assets, the lack of a unified privacy regulator creates ongoing challenges.

Divergent Agency Stances on Privacy

The U.S. financial privacy landscape is influenced by multiple agencies, including the Department of the Treasury, the Department of Justice (DOJ), and the SEC. Divergences in their approaches have led to confusion. For instance, Treasury's 2019 guidance on non-custodial crypto services was seemingly contradicted by the DOJ's enforcement actions against Tornado Cash developers. Although the DOJ has since softened its stance and the Treasury has sought public comment on the matter, a recent Treasury report acknowledged the lawful uses of privacy-enhancing technologies like mixers while also considering rescinding its earlier guidance. Concurrently, some SEC commissioners have questioned the necessity of current mandatory data-collection regimes.

The Cost of Surveillance and Outdated Systems

This regulatory back-and-forth has significant implications for software developers and individuals seeking financial privacy. The article argues that the long-standing practice of bulk data collection, stemming from the Bank Secrecy Act of 1970, has created a "government panopticon" that conflicts with democratic values. Financial institutions are compelled to monitor customers and report data, leading to over-disclosure and substantial compliance costs, estimated in the billions annually. Beyond financial expenditure, the greater cost is a "privacy deadweight loss," where economic and social activities are stifled because participants face a choice between full disclosure or non-participation. This effect is evident in the persistence of costly, outdated financial infrastructure and payment systems, as rational actors avoid systems that expose proprietary strategies or client information.

Technological Solutions and the Path Forward

The article highlights that modern cryptography, such as zero-knowledge proofs, offers a technological solution to these issues, enabling verification of compliance or eligibility without revealing sensitive data. This allows for private transactions on public blockchains. The author posits that if regulatory clarity can be achieved for securities and commodities laws, it can also be achieved for financial privacy. Recognizing financial privacy as both a civil liberty and an economic good is crucial. The piece concludes that market participants need clear legal requirements, as uncertainty, not just incorrect rules, can lead to market failure by deterring participation.
