U.S. bank groups warn of risks after Federal Reserve approves Kraken "skinny" master account

U.S. banking trade associations have criticized the Federal Reserve's decision to grant Kraken Financial a limited-purpose master account, arguing it could expose the payment system to risk without traditional bank-level safeguards. The approval has intensified calls for the Fed to finalize and clarify its framework for so-called "skinny" accounts for nontraditional financial institutions. Some crypto industry participants view the move as a significant step toward enabling payment-focused firms that do not rely on conventional deposit-lending models.
