Suitability Drift
Definition
Suitability drift is the divergence between a client's stated or inferred risk profile and their observed behavioral or portfolio risk state, created by life events, market shocks, or gradual behavioral change.
Why it matters
Suitability obligations under frameworks like the FCA Consumer Duty, MAS conduct requirements, and MiFID II are typically built around a risk profile captured once, at onboarding or annual review. Client behavior, however, changes continuously. A risk profile that was accurate six months ago may no longer reflect how a client is actually behaving today.
How it is detected
Suitability drift is detected by comparing observed behavioral signals against a client's stated profile and expressing the divergence as a 0–100 drift score.
Within tolerance
Behavior is consistent with the stated risk profile.
Mild drift
Small divergence worth noting at the next scheduled review.
Significant drift
Advisor should review before the next client touchpoint.
Critical drift
Advisor should prioritize a suitability review in the near term.
What triggers drift
Common triggers include life events such as a job change, divorce, inheritance, or retirement; market shocks that produce panic-sell behavior; changes in concentration anxiety; and sustained drops in client engagement.

How NeuFin detects it
NeuFin's suitability drift service combines output from its behavioral drift detector with the client's stated risk profile to compute a drift score and the leading reasons behind it, surfaced for advisor review.
