Treasury’s mixer language points to a new U.S. line on crypto privacy
A new Treasury report says lawful users may use mixers for financial privacy on public blockchains. The language leaves Treasury’s money-laundering case intact, while opening room for privacy tools that can operate inside regulated U.S. crypto markets.
In a report to Congress this week, the U.S. Treasury stated that lawful users of digital assets may use mixers to protect financial privacy on public blockchains.
Treasury provided ordinary examples, indicating that users may want to shield personal wealth, business payments, charitable donations, and consumer spending from full public view.
The same report maintained the department’s enforcement case. Treasury highlighted that criminals use mixing, bridging, and swapping to obscure audit trails, citing North Korean activity as a concern.
It added that bridges have received approximately $1.6 billion in deposits from mixing services since May 2020, with over $900 million reaching one bridge that later attracted scrutiny over ties to DPRK laundering.
Treasury’s wording marks a significant change in official language, shifting from describing mixers mainly through lenses of sanctions risk, darknet activity, ransomware payments, and state-backed theft.
The report incorporates lawful privacy use alongside those risks, indicating a narrower policy distinction between illicit concealment and supervised privacy services on public chains.
President Donald Trump set U.S. leadership in digital financial technology as a goal through executive order early in his term.
The July 2025 digital-assets report instructed Treasury to revisit its 2023 mixer proposal to ensure it blocks illicit finance while also protecting privacy and reducing regulatory burden.
However, these steps do not suggest a broad pardon for mixers; Washington seeks increased crypto activity, dollar-linked settlements, and institutional capital within domestic channels.
Once that becomes official policy, privacy may be seen less as an edge case and more as essential infrastructure for public-chain finance.
Treasury’s own numbers show why privacy is back in the policy record
Treasury’s report indicated that successful monthly transactions on public blockchains reached 3.8 billion in early 2025, reflecting a 96% increase year over year.
This scale modifies the policy question. A network processing billions of transactions monthly involves more than just traders and protocol users.
It starts to encapsulate payroll-related activities, treasury movements, commercial settlements, donations, and consumer payments. In this context, full public visibility presents a business risk for various lawful users, not merely a compliance advantage for investigators.
Treasury coupled that growth figure with a warning, reaffirming its position. The department also released a new money-laundering risk assessment, stating digital assets are increasingly used in conjunction with social media, encrypted messaging, and AI-enabled fraud.
A review from the FATF this month also indicated that the criminal misuse of stablecoins through peer-to-peer transfers and unhosted wallets is a rising concern.
This blend of signals points to a more selective U.S. approach. Treasury’s report suggested that custodial mixers, provided they register and comply as money services businesses, can generate off-chain information valuable to regulators and law enforcement.
Practically, that indicates privacy tools capable of preserving records, screening, and suspicious activity reporting, while maintaining pressure on tools that operate beyond those controls.
A hedge fund, issuer, or corporate treasury may seek confidentiality concerning counterparties, payment amounts, and wallet connections.
Treasury signals the government can embrace certain forms of confidentiality, given that service providers remain transparent to the state. The department is delineating boundaries around provider types, recordkeeping, and supervision rather than treating every privacy scenario identically.

The evolving policy landscape appears more skeptical than the optimistic interpretations circulating in certain circles. Treasury has not altered its perspective that mixers could be utilized as laundering infrastructure.
The department has recognized that lawful users on transparent blockchains may desire privacy, and that some providers might be able to deliver it within a regulated framework.
Institutional capital helps explain why the language changed now
The timing is likely influenced by the White House’s crypto agenda. The January 2025 executive order established digital asset leadership as a U.S. objective.
The March 2025 Bitcoin reserve fact sheet introduced a sovereign message concerning Bitcoin. The July 2025 digital-assets report urged agencies to alleviate unnecessary constraints while preserving anti-money-laundering regulations.
Treasury’s mixer language aligns with this progression.
Institutional flows contribute to the market dynamic. The regulated Bitcoin channel is noticeably substantial.
Data depicted about $1.7 billion flowing into spot bitcoin ETFs during a late-February to early-March window, despite instances of significant outflow.
While this does not definitively indicate institutional interest in mixer access, it highlights that large investors are already engaging with U.S.-approved crypto products at scale, shifting the policy discussion from whether institutions will enter the market to how the surrounding infrastructure will function when they do.
Privacy has integrated into that infrastructure conversation. Coinbase Institutional indicated in its 2026 market outlook that increasing institutional adoption is driving a demand for privacy technologies such as zero-knowledge proofs and fully homomorphic encryption.
Cambridge’s February 2026 analysis broadened this perspective, contending that sanctions pushed legitimate users away faster than they deterred criminals, and that the mixer market has transitioned towards more compliant privacy protocols.
The Cambridge figures are particularly informative, demonstrating how early this transformation remains. Institutions engaged in $1.22 trillion worth of stablecoin transactions over two years, yet only 0.013% of these transactions utilized privacy protocols, according to the same analysis.
This minimal percentage can support two interpretations: one indicates that institutional interest in privacy remains limited, while the other highlights a considerable privacy gap between the value institutions already transfer on-chain and the tools they currently utilize.
Bitcoin occupies a central role in this discrepancy. The asset is now entrenched within ETF frameworks, reserve policies, and large-scale portfolio allocations.
Its base layer also maintains high transparency. If the U.S. seeks to develop tokenized dollars, tokenized deposits, and public-chain settlements within domestic parameters, commercial users will continue to request methods for concealing counterparties and payment details without breaching compliance systems.
Thus, Treasury’s report implies that Washington has begun to recognize this demand as a component of market structure rather than solely a risk category.
The next phase will decide who gets privacy, and under what conditions
The forthcoming policy phase is likely to hinge on provider design. The White House has already instructed Treasury to revisit the previous mixer policy to safeguard privacy while alleviating burdens.
Treasury has now incorporated lawful privacy use into the official record. The unresolved question remains whether agencies will translate that language into a broader framework for regulated public-chain finance or restrict it to a narrow set of supervised intermediaries.
What happens from here?

For Bitcoin, the immediate implication is indirect. Treasury has facilitated a discourse allowing policymakers and regulated entities to argue that lawful users on public chains may require confidentiality tools for payments and settlements.
This argument benefits institutions, issuers, and market infrastructure providers significantly more than it does every open-source privacy project.
The crux of the issue revolves around who will be authorized to offer that confidentiality. Should banks, custodians, and other licensed entities control the majority, the policy shift will bolster institutional crypto growth while placing unregulated privacy initiatives under strain.
Conversely, a broader array of approved providers would signal a shift in U.S. policy. A narrower group would still represent a notable change, albeit one directed at regulated channels first.
Treasury’s March 2026 report arrives at a pivotal moment for the market. The White House aims for increased crypto activity onshore. Institutional funds are already flowing through regulated Bitcoin offerings.
Public-chain activity has surged to 3.8 billion successful monthly transactions. In this environment, Treasury has reinstated lawful financial privacy into the federal discourse.
The upcoming guidance will determine whether that privacy is reserved solely for supervised intermediaries or becomes integrated into the broader public-chain market structure within the United States.
