Bank Regulatory Data Dictionary

A catalogue and field-level mapping of the U.S. bank regulatory data universe — the forms, schedules, codes and identifiers that banks and bank holding companies file with the Federal Reserve, FFIEC, FDIC, NCUA and OCC. It exists to make these datasets discoverable, joinable and machine-readable.

What's inside

  • 42 collections spanning the full regulatory landscape (FR Y-9C, Call Report, FFIEC 009/101/102, FR Y-11/Y-14/Y-15/Y-9LP, FR 2052a, Pillar 3, FDIC/NCUA/OCC/UBPR).
  • 265 subschedules documented down to the line-item and MDRM-code level.
  • NIC structure reference plus 40 code lists describing bank corporate hierarchy.
  • An identifier crosswalk reconciling RSSD, FDIC Cert, LEI and other entity keys.
  • The MDRM meta-dictionary — the Micro Data Reference Manual code system that ties every field across every form together.

Start here

Looking for a specific schedule or concept? The Navigation Index maps every form, schedule, concept and reconciliation check to its guide and data file.

Browse the data

Prefer to explore the catalogues directly? The Data tables section renders the key CSVs as interactive, searchable and sortable tables — the collections and schedules catalogs, the MDRM crosswalk and namespaces, NIC code lists, identifiers and the code-validation audit — each with a one-click raw-CSV download.

Machine-readable data

Every guide is backed by structured data. The repository ships the underlying CSV and JSON files alongside this documentation:

  • csv/ — schedule catalogs, the MDRM master crosswalk, reconciliation formulas and validation rules.
  • json/ — schedule schemas, cross-form mappings and the full data taxonomy for automated pipelines.
