Sen. Warren Requests DOJ Criminal Probe of Bank of America Over AML Violations

A formal congressional request for a criminal investigation into the nation's second-largest bank by assets signals that regulatory scrutiny of Bank of America's compliance program may escalate...

Senator Elizabeth Warren (D-MA) has formally asked the Department of Justice to open a criminal investigation into Bank of America following the bank's admission of anti-money-laundering violations, according to a report published by CNBC on October 29, 2026. In her letter, Warren asked the DOJ to disclose by November 12 whether a criminal investigation has been launched.

Bank of America is the second-largest US bank by total assets, holding approximately $3.3 trillion in assets as of its most recent quarterly filing with the Federal Reserve. The bank's scale means any enforcement action affecting its operations or capital requirements would carry broad implications for US credit markets.

The senator's request centers on Bank of America's admitted violations of the Bank Secrecy Act and related anti-money-laundering statutes, which require financial institutions to monitor, detect, and report suspicious transactions to federal authorities. The CNBC report did not specify the dollar volume of transactions implicated in the admitted violations, and that figure has not been made public as of the date of this article.

Anti-money-laundering enforcement at major US banks has historically involved both the DOJ and the Financial Crimes Enforcement Network, a bureau of the US Treasury Department. Civil resolutions in past cases have included deferred prosecution agreements, consent orders, and monetary penalties. Whether the DOJ has already begun a criminal inquiry into Bank of America is not known; the November 12 deadline Warren set is the date by which she requested a response from the department, not a legal deadline binding on the DOJ.

Bank of America (ticker: BAC) trades on the New York Stock Exchange. The stock's reaction to Warren's letter, if any, had not been separately quantified in the source material available as of publication. Investor sensitivity to AML enforcement news at large banks has varied considerably depending on the scope and severity of the underlying violations disclosed.

Precedent for criminal-level AML enforcement against major US banks includes the 2012 deferred prosecution agreement with HSBC Holdings, in which the bank paid $1.9 billion to US authorities after admitting to failures that allowed drug cartel funds to move through its US subsidiary, according to DOJ records. More recently, TD Bank N.A. Pleaded guilty in October 2024 to Bank Secrecy Act violations and agreed to pay approximately $3 billion in penalties, as stated in a DOJ press release from that period. Those cases established that criminal-level resolutions are possible even for systemically important financial institutions.

Whether Bank of America's admitted violations are comparable in scale or nature to those prior cases is not established by the currently available public record. The specific findings that led to the bank's admission have not been detailed in any SEC filing or consent order made public as of October 29, 2026.

Warren's November 12 deadline for a DOJ response would serve primarily as a disclosure mechanism rather than a legal trigger. The DOJ is not legally required to respond to congressional inquiries within a senator's specified timeframe, though failure to respond may generate additional political pressure or congressional oversight activity.

For Bank of America shareholders, the material risk would depend on the form any eventual DOJ action takes. A deferred prosecution agreement would likely impose a monitor, remediation requirements, and a financial penalty. A guilty plea, as occurred with TD Bank in 2024, can carry additional regulatory consequences including restrictions on asset growth or business activities imposed by the Office of the Comptroller of the Currency or the Federal Reserve.

Bank of America has not issued a public statement in response to Warren's letter as of the time this article was prepared. The DOJ has not confirmed or denied the existence of a criminal investigation. What would clarify the scope of the matter is a public enforcement action, a DOJ response to Warren's letter, or a disclosure in Bank of America's next quarterly report filed with the Securities and Exchange Commission.
