In the letter, the senators accused the bank of evading their previous questions in its December response, writing that while the bank’s answers confirm the extent of its failure to monitor and report suspicious financial activity, it failed “to provide key information needed by Congress to understand why and how these failures occurred.” The bank’s “repeated reference to ‘confidential supervisory information’” as a justification for its refusal to provide the requested information “is simply not an acceptable rationale,” the senators said. They also noted that the bank’s recent advance from the Federal Home Loan Bank of San Francisco—intended “to ‘stave off a further run on deposits’”—has introduced additional crypto market risks into the traditional banking system, especially should the bank fail. The bank was asked to explain how it plans to use the $4.3 billion it received.

The senators further commented that additional findings have revealed that neither the Federal Reserve nor the bank’s independent auditors were able to identify the “extraordinary gaps” in the bank’s due diligence process. The senators asked the bank to provide responses to questions related to its risk management policies, as well as how many safety and soundness exams were conducted, and whether any of the bank’s executives were “held accountable” for the failures related to the collapsed exchange, among other things.
