Data on what the federal banking agencies examine, write, and enforce
— from the National Banking Acts to the present.
Hover an office for detail. Select an agency to isolate its network.
Offices of the three federal banking agencies. Large markers are Reserve
Banks and regional offices; small markers are branches and field offices;
squares mark the three Washington headquarters. Six cities host more than
one agency. The FDIC's San Juan field office is not shown.
Three federal agencies supervise American banks: the Office of the
Comptroller of the Currency (1863), the Federal Reserve (1913), and the
Federal Deposit Insurance Corporation (1933). Each leaves a long written
record — annual reports, examination handbooks, guidance letters, risk
assessments, enforcement orders. Most of what we know about that record
comes from the accounts of the people who made it. Those accounts are
indispensable, but they cannot be checked at scale, because no one had read
the record at scale.
This project reads it. We convert the supervisory record into measurement
— structured series of examination emphasis, industry structure, and
bank-level risk that can be compared across agencies and across 160 years
— so that claims about what supervisors did, and when, can be tested
against the evidence rather than taken on authority. The aim is a common,
independent factual basis for the people who study, practice, and set bank
supervision: a record open to scrutiny.
What the agencies are writing about now: quarterly topic emphasis in
guidance letters, bulletins, and risk reports since 1989.
Briefs
Each quarter we publish a short brief on the state of bank supervision: what
moved, what diverged across agencies, and how current emphasis compares with
the historical record.
Read the current brief.
Research
The measurement behind the site is developed in
academic work on the history and political economy
of bank supervision.
