US Treasury withdraws crypto wallet surveillance plan

TLDR

The US Treasury has dropped two controversial plans to expand reporting on self-custody crypto wallets and mixing services, leaving the current rules in place.

1. FinCEN withdrew its 2020 proposal for extra recordkeeping and reporting on transactions involving self-custody, or unhosted, wallets, as well as a 2023 rule targeting crypto mixers.
2. For users and exchanges, nothing new is imposed now, but existing Bank Secrecy Act, KYC, AML and sanctions rules still fully apply to regulated crypto activity.
3. Regulators can revisit wallet and mixer rules later, so the main change is removing a long running regulatory overhang rather than locking in a permanent win for privacy.

Deep Dive

1. What Treasury Withdrew

The Treasurys Financial Crimes Enforcement Network (FinCEN) has formally withdrawn two proposed rules that never took effect but had been pending since 2020 and 2023. One would have extended Bank Secrecy Act obligations to transfers involving self-custody wallets by requiring banks and money services businesses to keep records for transactions above 3,000 dollars and report transactions over 10,000 dollars, including counterparty details, whenever an unhosted or certain foreign hosted wallet was involved.

A second proposal would have designated international crypto mixing as a class of transactions of primary money laundering concern under Section 311 of the USA PATRIOT Act, obliging institutions to report mixing linked activity and retain detailed customer and transaction identifiers such as wallet addresses and IP data. FinCEN has now said it will take no further action on these notices, and the proposals are being removed from the Federal Register, as summarized in the withdrawn wallet and mixing rules on unhosted wallets and CVC mixing.

2. Impact On Crypto Users And Businesses

Because neither proposal was finalized, their withdrawal leaves the legal baseline unchanged rather than rolling back active rules. Regulated exchanges and custodians must still perform KYC, run AML programs, file suspicious activity reports and screen against sanctions, and users of those platforms remain subject to existing monitoring.

The practical relief is for compliance teams that had been preparing for expanded reporting on self custody counterparties and foreign mixing, and for privacy tools that faced the risk of broad, category based reporting obligations. Several industry groups framed the move as a win for financial privacy, and FinCEN itself acknowledged that the mixing rule could have had a chilling effect on lawful activity and imposed heavy reporting burdens.

3. What To Watch Next

FinCEN explicitly retains its authority under the Bank Secrecy Act and Section 311, and it stated that it will continue monitoring mixers and other crypto activity for money laundering and terrorist financing risks in its withdrawn mixer and wallet proposals. Future rules could be narrower, more targeted at specific services or jurisdictions, or paired with ongoing sanctions and enforcement actions.

At the same time, other agencies are moving in parallel. The CFTC is advancing its own rulemaking for crypto markets, and the broader US regulatory framework for exchanges, stablecoins and custody continues to evolve, even as this specific surveillance push was shelved.

Conclusion

Treasurys decision removes two broad, controversial surveillance proposals that hung over self custody wallets and mixers, without changing existing AML and KYC duties. For crypto users and builders, it lowers immediate compliance uncertainty and supports more normal use of self custody, while leaving open the possibility of more focused rules or enforcement if regulators see new risks or abuses.
