US Treasury signals regulated crypto privacy may have a future in the US

The U.S. Treasury has indicated that lawful users of digital assets may employ mixers for financial privacy on public blockchains, a shift in official language that acknowledges legitimate privacy needs while maintaining the department's ability to combat illicit finance. This nuanced approach opens the door for privacy tools operating within regulated U.S. crypto markets.

Treasury Report Acknowledges Lawful Privacy Use

A recent report to Congress from the U.S. Treasury stated that ordinary users might use mixers to shield personal wealth, business transactions, charitable donations, and consumer spending from public view. This statement marks a significant departure from previous years, where mixers were primarily discussed in the context of sanctions risk, darknet activity, and state-sponsored theft. The report, however, also reinforced the department's enforcement stance, highlighting the use of mixing, bridging, and swapping by criminals to obscure audit trails, particularly noting North Korean activity. Approximately $1.6 billion has been deposited into bridges from mixing services since May 2020, with over $900 million reaching a bridge that later faced scrutiny for its role in DPRK laundering.

Policy Shift Driven by Market Growth and Institutional Interest

The evolving language is partly driven by the massive scale of public blockchain transactions, which reached 3.8 billion successful monthly transactions in early 2025, a 96% year-over-year increase. This growth means public blockchains are increasingly handling payroll-adjacent activity, treasury movements, commercial settlements, donations, and consumer payments, making full public visibility a significant business risk for many lawful users. Concurrently, the U.S. has set a goal to lead in digital financial technology, with executive orders and reports directing agencies to reduce regulatory burdens while maintaining anti-money-laundering controls. Institutional capital is also a key factor, with approximately $1.7 billion flowing into spot Bitcoin ETFs in a late-February to early-March window, indicating that large investors are already engaging with crypto through regulated products.

Balancing Privacy with Regulatory Oversight

The Treasury's approach suggests a more selective U.S. strategy, distinguishing between illicit concealment and supervised privacy services. Custodial mixers that register and comply as money services businesses may still generate off-chain information valuable to regulators. This implies a focus on privacy tools that preserve records, screening, and suspicious activity reporting, while maintaining pressure on tools operating outside these controls. The department is signaling a willingness to accept certain forms of confidentiality if service providers remain transparent to the state, drawing lines around provider type, recordkeeping, and supervision rather than treating all privacy use cases identically. This contrasts with the significant gap between institutional scale and actual privacy-tool usage, as only 0.013% of $1.22 trillion in institutional stablecoin transfers touched privacy protocols over two years, according to a February 2026 Cambridge analysis.

Future Outlook for Crypto Privacy

The next phase of policy will likely focus on provider design, determining whether agencies will establish a broad framework for regulated public-chain finance or confine it to a narrow set of supervised intermediaries. The base case scenario involves Treasury and other agencies making room for privacy tools that maintain record-keeping and reporting, while continuing to scrutinize open-ended obfuscation. This could lead to licensed providers offering privacy features for onchain payments and settlement. The bull case suggests compliant privacy tools becoming standard for tokenized dollars and large transfers, significantly increasing the usage of privacy protocols. Conversely, the bear case anticipates Washington using the new language to favor permissioned systems, with FATF pressure and enforcement actions further isolating non-custodial privacy tools. For Bitcoin, this shift indirectly supports arguments for confidentiality tools on public chains, benefiting institutional players and market infrastructure providers more directly than permissionless privacy projects.
