AI is a credible efficiency tailwind, but not an earnings inflection +44-20-7568 3580

We view AI as a credible efficiency tailwind for Nordic banks, but not a near-term Joshua Humphreys

meaningful, but consistent with gradual improvement rather than step-change. Our +44-20-7567 0385

base case reflects around ⅔ of this theoretical benefit by 2030.

The debate needs to be about retention, not potential

The key question is no longer whether AI improves productivity, but how much of that

benefit banks retain in the P&L. Adoption will require higher technology spend and

ongoing run-rate costs, with cost-to-achieve possibly a key differentiator. We see risk

that productivity gains are partially competed away through pricing or reinvestment into

growth. How much is ultimately retained remains uncertain, but key.

Business and cost mix drives dispersion in outcomes

The opportunity is meaningful, but not uniform. Top-down, based on available

literature/surveys suggests ~25% efficiency potential in Central Functions, ~15% in

Retail & SME, and ~5% in CIB/Wealth, reflecting differing levels of process intensity and

AI addressability. In our analysis, business and cost mix is the key driver of

dispersion. Importantly, this framework captures opportunity, not execution likelihood.
