Supervisory Alignment Index
How much of a bank's supervisor's attention falls on that bank's vulnerabilities — quarterly, for every insured bank.
Supervisory risk is not the same for two banks with the same balance sheet. A bank loaded with credit risk faces more supervisory pressure when its examiner is focused on credit than when the examiner is focused on something else. The index measures that alignment directly. For each bank and quarter, it weights the bank's standardized exposures across four prudential domains — credit, capital, liquidity, and market and interest-rate risk — by the share of attention its primary federal supervisor is currently devoting to each domain. A positive value means the supervisor's attention is concentrated where the bank is exposed; a negative value means the bank's risks lie where its supervisor is not looking.
Purpose
The index exists to bring supervisory attention down to the level of the individual bank. Aggregate measures of what supervisors emphasize cannot say whether the emphasis lands where the risk is; that requires pairing each bank's exposures with its own supervisor's current focus. This index does that for every insured institution and quarter, turning a system-level signal into a bank-level one. It lets researchers ask whether supervision is well targeted, whether alignment predicts outcomes, and how it differs across the three agencies; it lets a bank see where it sits in its supervisor's field of view. The goal is a transparent, time-varying measure of how closely supervision is aimed at each bank's actual vulnerabilities.

The series
Reading it
The index varies in both dimensions that matter. Across banks, business models differ: in any quarter, lenders with concentrated loan books and thin capital sit at the top of the distribution, while liquid, well-capitalized banks sit at the bottom. Over time, the supervisors move: when an agency shifts attention toward liquidity, as all three did after 2023, the index rises for every funding-constrained bank it supervises and falls for banks whose risks lie elsewhere. Divergence across the agency means is itself informative — it shows the three supervisors pointing at different parts of the same banking system.
