U.S. Representative Maxine Waters has raised concerns over the Federal Reserve Bank of Kansas City's decision to grant crypto exchange Kraken a limited "master account." Waters, the ranking Democrat on the House Financial Services Committee, sent a letter to Kansas City Fed President Jeff Schmid, questioning the legal basis and consumer protection implications of this approval. She highlighted that the Federal Reserve's guidelines do not mention a "limited purpose account," urging clarification on Kraken's account terms and the approval process. Kraken's new account provides direct access to Federal Reserve payment services, a privilege sought by many crypto firms. The Kansas City Fed announced the approval earlier this month, emphasizing its commitment to maintaining a competitive and stable financial system. The bank has acknowledged receipt of Waters' letter and is reviewing it.
