Treasury’s Crypto Rule Rollback: Privacy Win or Trap?

The decision follows a July 2025 report from the President’s Working Group on Digital Asset Markets. Markets reacted modestly. Coinbase stock rose about 3% to $188, while Bitcoin slipped less than 1% to around $85,690.

The Mixer Proposal That Never Got Finished

In 2023, FinCEN proposed classifying international crypto mixing as a “primary money laundering concern” under Section 311 of the USA PATRIOT Act. Mixers pool coins from many users, which makes it hard for outside observers to trace the funds. The proposal would have required banks and exchanges to report mixing-related transactions.

The withdrawal notice acknowledges concerns about how broadly mixing was defined. It also cites the Working Group’s emphasis on protecting the privacy of lawful users on public blockchains.

A Wallet Rule Declared Dead, Again

FinCEN also formally ended a rule covering self-custody wallets, which owners control directly without an intermediary. The December 2020 proposal would have required reporting of transactions over $10,000, including multiple transactions totaling more than $10,000 within 24 hours.

The rule had already been marked as withdrawn in April 2024, and the October 5 notice makes its end official. Jason Somensatto of Coin Center called it a major privacy victory.

What Exchanges Still Have to Do

Existing anti-money laundering (AML) obligations for regulated exchanges are unchanged, and FinCEN never finalized either proposed rule. Exchanges avoid possible future reporting costs, but their current duties stay in place:

• Know-your-customer (KYC) identity checks under the Bank Secrecy Act
• A maintained AML program
• Suspicious activity reports
• Office of Foreign Assets Control (OFAC) sanctions screenings

Most investors on regulated exchanges will see no practical difference. The changes mainly benefit users of self-custody wallets and privacy-focused services.

Hashlytics Take

The win is real, but it is smaller than the headlines suggest. Neither rule was ever finalized, and the wallet rule had sat in withdrawn status since April 2024, so day-to-day compliance barely moves. The detail worth watching is that FinCEN keeps its Section 311 authority and can still go after specific mixers. Treasury has traded a blanket definition for a case-by-case tool, which may be better for ordinary users but leaves the underlying fight unsettled.
