The Federal Reserve has granted a crypto firm, Kraken Financial, direct access to America's core payments systems for the first time, a breakthrough that could reshape the $2.3 trillion digital asset industry. The move, which allows Kraken Financial to move money on Fedwire, the same rails used by thousands of the nation's banks and credit unions, will allow the company to handle transactions more quickly for its clients and professional traders. However, it will not offer the full range of services such as payment of interest on reserves held at the Fed. The decision comes as crypto entrants have been stalled in their search for operating approval under tight U.S. banking regulations.
