U.S. Senators Elizabeth Warren, a Massachusetts Democrat, and Roger Marshall, a Kansas Republican, announced the Digital Asset Anti-Money Laundering Act of 2022 on December 14, 2022, proposing one of Congress’s broadest attempts up to that point to bring cryptocurrency activity under the Bank Secrecy Act.
The senators released their proposal as the Senate Banking Committee held a hearing on the collapse of FTX and harm to customers. The timing connected two distinct policy questions: how to supervise centralized companies entrusted with customer assets, and how far financial-surveillance duties could extend into decentralized networks.
The measure was only a proposal on December 14. It had not passed either chamber, become law or produced implementing rules.
What the proposal covered
The sponsors’ bill text directed the Financial Crimes Enforcement Network, or FinCEN, to classify custodial and unhosted wallet providers, cryptocurrency miners, validators, certain nodes, independent network participants including maximum-extractable-value searchers, and some protocol-level validators as money services businesses.
That classification was the proposal’s central break with the existing policy debate. Exchanges and other custodial intermediaries could identify customers because they maintained account relationships. Miners, validators and software-based network participants generally processed or ordered transactions without necessarily possessing comparable customer records. Applying money-service-business obligations to those actors therefore raised unresolved questions about who would be identified, when an obligation would attach and whether some participants could comply at all.
The text also would have required FinCEN to complete a December 2020 rulemaking concerning certain transactions involving unhosted wallets. It proposed reports for U.S. persons conducting more than $10,000 in digital-asset transactions through one or more foreign accounts, using the foreign-account reporting framework specified in the bill.
Separate provisions would have prohibited financial institutions from handling digital-asset mixers, privacy coins and other Treasury-specified anonymity-enhancing technologies, as well as assets anonymized through them. The proposal further called for compliance-examination processes at Treasury, the Securities and Exchange Commission and the Commodity Futures Trading Commission. Digital-asset kiosk operators would have faced address-reporting and customer-identification requirements.
A dispute larger than exchanges
Warren and Marshall presented the measure as an effort to close anti-money-laundering and sanctions-enforcement gaps. That was the sponsors’ policy claim, not an established finding that every covered network participant functioned like a bank or broker.
Coin Center, a cryptocurrency policy advocacy organization, responded on December 14 that the legislation threatened self-custody, developers and node operators. Its criticism was also an interested party’s legal and policy position, not a court ruling. The disagreement nevertheless captured the proposal’s significance: it shifted the regulatory boundary from companies holding customer funds toward portions of the technical infrastructure that validates or facilitates public-blockchain transactions.
That distinction mattered in the FTX context. The Senate Banking Committee’s December 14 hearing examined the failure of an offshore-centered exchange group and competing approaches to consumer protection. The Warren-Marshall proposal principally targeted illicit-finance controls across digital-asset activity. It did not itself establish custody segregation, exchange capital requirements or a bankruptcy framework for returning customer property.
What was knowable on December 14
The verified event-day record supports a narrow conclusion: two senators from different parties publicly unveiled a far-reaching anti-money-laundering proposal while Congress was examining FTX. Bipartisan sponsorship gave the proposal institutional significance, but two sponsors did not demonstrate broader congressional support or forecast enactment.
No market-price inference is warranted from the surviving sources. They establish the proposal, its provisions, the hearing context and the immediate policy dispute, but they do not isolate any effect on bitcoin, ether or other digital-asset prices.
Later procedural context
The Government Publishing Office records S. 5267 as formally introduced on December 15, 2022, read twice and referred to the Senate Banking Committee. That next-day action clarifies the chronology but does not change the December 14 event: the sponsors announced the measure and released its substance before its formal Senate introduction.
