The Supervisory Compass: 160 Years of What Bank Examiners Focus On

Andrew Bird (Chapman University) · Stephen A. Karolyi (George Mason University) · Thomas G. Ruchti (Virginia Tech) · working paper, 2026

We construct the Supervisory Priorities Index, the first continuous measure of what bank supervisors focus on, from examination documents spanning 1863 to the present across the three federal banking agencies. Institutional architecture explains virtually all variation in supervisory emphasis; financial crises and political transitions contribute little. Formal regulation and supervisory emphasis are complements for codifiable risks but substitutes for judgment-intensive domains. Within-county comparisons of banks facing different regulators show that domain-specific supervisory emphasis moves deposits and lending in economically meaningful ways.
