Screening

Sanctions Screening

Sanctions Screening is the process of checking customers, counterparties, and transactions against domestic and international sanctions and watchlists — such as OFAC, the UN, EU, and UK HMT — to prevent dealings with designated parties.
See Sanctions Screening Back to Glossary

Sanctions screening is non-negotiable and strictly liability-based: doing business with a designated party is a violation regardless of intent, with penalties reaching eight or nine figures. Firms must screen at onboarding, continuously as lists update, and on transactions in real time.

The operational challenge is false positives. Literal name matching flags every similar name, so effective screening uses tuneable fuzzy matching, transliteration handling, and clear match-reasoning so analysts can disposition alerts quickly and defensibly.

Key points

  • Strict-liability — intent is irrelevant to a violation
  • Required at onboarding, on transactions, and on every list update
  • Covers OFAC, UN, EU, UK HMT, MAS, and other lists
  • Needs fuzzy matching and strong false-positive controls

Frequently asked

How often should sanctions screening run?+
Continuously. Customers should be re-screened automatically every time a relevant list is updated — not in an overnight batch — because a newly designated entity must be caught before the next transaction.
