Foundations
The American financial system is built upon a fragmented, charter-based, dual state–federal architecture — assembled piecemeal across two and a half centuries.
Two hundred and forty-five years separate Robert Morris's Bank of North America from the GENIUS Act of 2025. In between sits no master plan: a sequence of crises, statutes, and reorganizations that produced a system of overlapping regulators governing thousands of institutions. Unlike the unitary supervisory architectures of the United Kingdom, France, or Japan, the United States retains a dual banking system — banks may hold a state or federal charter — and apportions oversight by charter type more than by activity. To understand who regulates whom, one must first understand which paper a firm holds.
After the Congressional Research Service's classification framework (R44918, IF11065), federal financial regulators sort into five functional buckets, plus interagency coordination bodies.
