Model-risk framework for Cobalt Bank

A model register with risk tiers, an audit trail from data to decision, and a policy set mapped to the regulation clause by clause.

14 days

to audit-ready, from ninety

How it was measured 

Measured as elapsed days from a formal information request to a complete, evidenced response, across three requests before and two after. Stated this way because a figure without its method is a claim. Ask us for the workings: we will send them.

On the engagement
“The examiner's word for the register was “unusually legible”. We framed that.”
Head of Model Risk, Cobalt Bank2025 · outcome 14 days

Three movements.

01

The challenge

An examiner asked how a lending decision had been reached, and the answer took nine days to assemble from four teams. Nothing was wrong; nothing could be shown to be right either.

02

The approach

A model register with risk tiers, owners and review dates the risk team maintains without us, and an audit trail that reconstructs any decision from the data that produced it. The policy set was mapped to the regulation clause by clause.

03

The result

The next examination request was answered in fourteen days end to end, from ninety. The register is now maintained by two people who do not work for us.

The engagement, on paper.
