AI agent for risk managers

Credit Scorecard Backtest Agent

Show whether the scorecard still ranks risk correctly and what cutoff changes would do

Credit Scorecard Backtest Agent: what goes in, what the agent does and what you get

What it does

A scorecard built three years ago still approves loans, but defaults are creeping up in some segments. This agent scores a past cohort with the current scorecard and compares the predicted and actual default rates. It checks stability across segments such as region, product and score band, and measures how far each has drifted. It flags segments where predictions are off by more than a set amount. It then tests alternative cutoffs and reruns the comparison to see their effect on approval rate and loss rate. It documents each run so results are reproducible. The risk lead approves any change to the scorecard. Edge case: a segment with too few loans is reported as insufficient data rather than drift.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

It flags a segment when predicted default differs from actual by more than 20 percent with enough loans and picks cutoffs that keep losses within target.

  • Require at least 200 loans per segment
  • Flag drift above 20 percent
  • Pick cutoffs that keep losses within target
  • Log every run with its inputs

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Minimum loans per segment (default 200)
  • Drift tolerance (default 20 percent)
  • Cutoffs tested (default plus and minus 15 points)
  • Run frequency (default quarterly)

What keeps you in control

It always asks you first

  • Risk lead approves any scorecard or cutoff change

Hard limits

  • Never change the live scorecard
  • Never use data that is not in the cohort
  • Keep results reproducible

It stops when

  • Done: Report approved and decisions recorded
  • Stop: Outcome data is incomplete, so hand to the risk lead

An example run

What happensFor 12,400 loans, predicted default is 4.1 percent and actual 4.6 percent overall. In the small business segment predictions are 3.0 against 4.4, 47 percent off, so it is flagged. A cutoff raised by 15 points reduces the segment default to 3.5 and cuts approvals by 6 percent. The risk lead approves further testing.
