rewrite this title Coinbase Tells US Treasury Old AML Rules Are ‘Broken,’ Pushes Tech Fixes for Crypto Crime – Decrypt

Coinbase has urged the U.S. Treasury Department to scrap decades-old anti-money-laundering rules, calling them obsolete, and to adopt AI and zero-knowledge proofs to fight financial crime in digital assets.

The crypto exchange sent a letter to the Treasury on Friday, responding to the agency’s request for comment on innovative methods to detect illicit activity involving digital assets.

“When bad guys innovate in financial crime, good guys need innovation to keep pace,” Coinbase Chief Legal Officer Paul Grewal tweeted Monday..

Treasury initially published the request in the Federal Register in August.



In a blog post published in August, Grewal wrote that “The Bank Secrecy Act Is Broken. Technology Can Fix It,” saying the current compliance system is “rooted in decades-old requirements that reflect paper-based protocols designed for a financial system” where fund transfers take days.

The exchange has now called for establishing regulatory safe harbors under the Bank Secrecy Act for firms responsibly deploying AI to improve compliance programs, with conditions focusing on governance and outcomes rather than forcing a one-size-fits-all model. 

Federico Fabiano, Head of Legal & Compliance at Hex Trust, told Decrypt that “the era of ‘check-the-box’ compliance needs to evolve,” saying that reliance on existing laws may no longer be tenable. 

“We must collectively govern the integration of transformative tools like AI, which, powered by the immutable transparency of the blockchain, can finally move AML past the problem of low-value, static data,” Fabiano said, calling the evolution “an opportunity, not a constraint” essential to securing a credible, compliant financial ecosystem.

Coinbase says the high compliance costs pose “formidable barriers to entry for smaller financial service providers, including fintech startups,” and are often passed on to customers through higher banking fees and denial of financial services, particularly affecting low-income customers.

Identifying the problem

Coinbase also urged Treasury to issue guidance clearly recognizing API-driven compliance technologies, including outlining acceptable use cases, data privacy requirements, and interoperability standards.

“The U.S. needs to move on this—now,” Grewal tweeted.

The letter says current rules force Americans to complete new KYC checks for every financial account, sharing their data “with dozens of companies” that must store it for years, creating “honeypots for criminals.” 

It urges updating the Bank Secrecy Act to recognize decentralized IDs and zero-knowledge proofs as valid identity-verification methods.

Coinbase further requested that the Treasury publish guidance explicitly recognizing Know-Your-Transaction screening and blockchain analytics clustering as more effective compliance methods.

Coinbase said financial institutions file over 25 million reports to FinCEN each year, mostly on lawful activity, yet “the vast majority never result in a follow-up,” and despite a 2020 law to modernize the system, “little, if any, progress has been made.”

Privacy advocacy group Coin Center also submitted a response, with Executive Director Peter Van Valkenburgh warning that stablecoins on public chains with traditional AML requirements could create a “CBDC-style panopticon.”

Treasury will compile responses into a congressional report for the Senate Committee on Banking, Housing, and Urban Affairs and the House Committee on Financial Services, who will then formulate relevant guidance and legislative proposals.
