Trend tagging is the practice of classifying regulatory updates by thematic category—fraud, consumer protection, operational resilience, digital assets, etc.—so that patterns become visible across jurisdictions and time. In 2024, multiple regulators simultaneously tightened instant payment fraud rules, a pattern that firms with trend tagging detected months ahead of peers. Without tagging, each update appears isolated; with it, an emerging regulatory consensus becomes visible early enough to act on strategically.
