Data as of · sourced from FFIEC call reports. How we update
An exploratory screening score that ranks relative failure risk across filers. It is not a calibrated probability, not a credit rating, and not a CAMELS rating. Held-out test AUC 0.904 for the 1-year horizon (v20261005_114304). Trained on credit-driven community-bank failures, it carries little signal for interest-rate or deposit-flight risk. The score covers every FDIC-insured bank in the latest run, but the model was trained on community and regional banks and its accuracy above roughly $10 billion in assets is not established, so a low score is not evidence of safety. See the model evidence and limits and the methodology. This is not investment advice or a credit rating.
