The US Treasury Department has, for the first time, officially recognized that lawful users of digital assets may utilize tools like mixers on public blockchains to safeguard their financial privacy. In a new report to Congress, the department signaled a shift in tone by acknowledging that privacy-enhancing technologies are not exclusively linked to illicit activities—a move seen as breaking new ground in official policy statements.
Legal and Commercial Applications for Privacy Tools
The report points out that both individuals and organizations may wish to keep details such as personal wealth, corporate payments, donations, or everyday expenditures out of the public eye. In previous years, the Treasury generally discussed mixers in the context of sanctions risk, ransomware payments, and state-sponsored criminal operations. Now, by formally recognizing financial privacy as a legitimate justification for using these technologies, the department has broadened the debate about their role in the digital economy.
Balancing Regulation and Privacy
While maintaining its commitment to sanctions enforcement and the investigation of obscure or criminal blockchain transactions, the Treasury also opened the door to the lawful operation of mixers and similar privacy services. The report indicates that if privacy is provided by registered and regulated service providers, oversight authorities could receive necessary information while still allowing for legitimate privacy protection.
Growth in Blockchain Activity Spurs Business Concerns
Data presented in the report highlights that the volume of monthly transactions on public blockchains surged to 3.8 billion at the start of 2025, marking a remarkable 96 percent annual increase. This dramatic expansion isn’t limited to speculative trading—it now encompasses uses like payroll, charitable giving, internal corporate transfers, and routine spending. For larger-scale transactions, privacy has become vital not only for regulatory compliance but also for protecting sensitive commercial information.
Institutional Capital Flows and Crypto Infrastructure
Policy documents shaped in the first quarter of 2025, rooted in the US digital financial technology vision crafted during President Donald Trump’s administration, are designed to encourage more institutional capital and dollar-related transactions to flow through American channels. Recent months saw approximately $1.7 billion of new investment in spot Bitcoin ETFs, with various market reports confirming strong institutional interest in regulated cryptocurrency products.
The State of Privacy Technologies and Future Prospects
A February 2026 study from Cambridge University reveals that institutions conducted $1.22 trillion in stablecoin transactions over the previous two years, yet only a minuscule 0.013 percent of this volume used privacy protocols. These figures suggest that while corporate demand for privacy remains limited for now, the potential gap—and therefore the demand—could be substantial in the future.
Meanwhile, the latest findings from the Financial Action Task Force (FATF) and ongoing assessments by the Treasury highlight an increase in the use of cryptocurrencies for laundering criminal proceeds. They warn that advances such as social media scams, encrypted messaging, and artificial intelligence–driven fraud are diversifying illicit tactics. Treasury data shows mixer-associated transaction volumes have reached $1.6 billion since May 2020, with much of this activity routed through specific bridges between blockchain networks.
On the user side, Coinbase Institutional’s 2026 market outlook emphasizes rising institutional adoption has sparked renewed interest in advanced privacy technologies, including zero-knowledge proofs and fully homomorphic encryption. Aside from technical discussions, regulatory focus now centers on which providers can offer privacy services within the boundaries of the law, and under precisely what conditions.
In summary, the Treasury has officially documented that users operating legally may require privacy for payment and settlement processes. How this principle is put into practice will ultimately depend on the involvement of regulated infrastructure providers and the nature of supervisory systems applied to them.
