Him Das said FinCEN’s current authority under the PATRIOT Act would 
likely not stop actors from engaging in illicit transactions for 
ransomware attacks and darknet markets. 
Him Das, the acting director of the United States Financial Crimes 
Enforcement Network, or FinCEN, said some of the government bureau’s 
tools to fight money laundering and terrorism financing may be ill 
suited for crypto.
In a Thursday hearing of the House Financial Services Committee on "Oversight of the Financial Crimes Enforcement Network," Das addressed
 concerns from lawmakers regarding FinCEN’s authority to pursue 
information on illicit digital asset transactions. Kentucky 
Representative Andy Barr said many of the current "special measures" 
FinCEN was authorized
 to use under Section 311 of the PATRIOT Act were “rarely used,” while 
Das hinted that digital assets were essentially new ground for the law 
aimed at Anti-Money Laundering, or AML, and Countering the Financing of 
Terrorism, or CFT.
“Section 311 was enacted in a time when most 
financial relationships and transactions were done through the 
traditional banking system where there are traditional correspondent 
account relationships,” said Das. “Nowadays, cross-border transactions 
often include money services businesses, payment systems, [...] foreign 
exchange houses as well as cryptocurrency.”
Das added that 
FinCEN’s current authority under the PATRIOT Act would likely not stop 
actors from engaging in illicit transactions for ransomware attacks and 
darknet markets: 
“Currently, the Section 311 authority
is not right-sized for the types of threats that we’re seeing through
the use of cryptocurrency.”

In
 addition to questions regarding FinCEN’s authority to assess suspicious
 transactions, many lawmakers questioned how the bureau might handle 
Russian oligarchs and entities using cryptocurrency to evade sanctions. 
Das reiterated FinCEN’s position from March
 that the Russian government was unlikely to use convertible virtual 
currencies to evade large-scale sanctions, but would continue to monitor
 the situation:
“We’ve not seen large-scale evasion
through the use of cryptocurrency, but we’re mindful of that and we’re
working with financial institutions so that they’re aware of that
potential that we can identify a large-scale evasion using
cryptocurrency and act on it as well.”

According
 to Das, FinCEN will also be considering how to handle financial 
monitoring requirements for crypto firms that facilitate certain 
transactions to self-custodied, or unhosted, wallets. The U.S. Treasury 
Department proposed Know Your Customer rules on unhosted wallets  for transactions of more than $3,000 in December 2020 and hinted
 in its semiannual agenda and regulatory plan released in January it 
would be looking at regulating this aspect of the crypto space.
“It’s
 not that unhosted wallets are entirely opaque,” said Das. “Unhosted 
wallets often engage in transactions with cryptocurrency exchanges, 
which are subject to AML/CFT regulation [...] Law enforcement can engage
 with cryptocurrency exchanges with respect to suspicious activity 
reporting and other reports that might be applicable to them in terms of
 getting some degree of understanding in terms of transactions with 
unhosted wallets as well.”
