KYC Review Date Current

freshnesscritical

Validates that the KYC review date is not stale based on the customer risk rating. High-risk customers must have KYC refreshed within 1 year, medium-risk within 2 years, and low-risk within 3 years. Stale KYC reviews expose the institution to regulatory risk and may indicate gaps in ongoing due diligence.
