City National Bank is a national bank chartered in the United States and a wholly owned subsidiary of Royal Bank of Canada (RBC) since 2015, headquartered in Los Angeles, California and known historically as "the bank to the stars" for its deep roots in the entertainment industry. With roughly $98 billion in assets, it is an FDIC-insured, super-regional institution offering personal, business, and private banking, wealth management, treasury management, and capital markets services, with industry expertise across entertainment, healthcare, real estate, technology, and law. City National operates as CN Bank in Florida. It runs NO first-party public developer portal or documented public API: developer.cnb.com and developers.cnb.com do not resolve and api.cnb.com returns 404. Consistent with the voluntary, fragmented US open-finance model, consumer-permissioned account data is reached through third-party aggregators (Plaid, MX, Finicity, Akoya) rather than a direct City National API. As a covered depository institution it falls under the emerging CFPB Section 1033 Personal Financial Data Rights rule, but no City-National-specific 1033 or FDX participation posture is publicly documented. Its Canadian parent RBC runs a separate developer portal (developer.rbc.com) under a different charter that does not expose City National Bank APIs.
