Circle Internet Group (CRCL) surged 11.5% to $70.25 today after receiving final approval from the U.S. Office of the Comptroller of the Currency (OCC) to establish Circle National Trust, a national trust bank. This regulatory milestone places the bank under direct federal oversight, strengthening the infrastructure for its USDC stablecoin through federally regulated digital asset custody. The approval is expected to enhance the credibility and security of USDC, with potential future services for institutional clients and management of USDC reserves under federal oversight.
