Sanctions and OFAC Screening for FinTechs

Sanctions compliance is its own regime, and fintechs constantly conflate it with anti-money-laundering. It's related but distinct. Sanctions are administered by the Office of Foreign Assets Control, OFAC, under authorities like the International Emergency Economic Powers Act.

They are not part of the Bank Secrecy Act; they're a parallel, mandatory obligation. Two things make OFAC especially unforgiving. First, liability is essentially strict: you can violate sanctions even without intent or knowledge, which means 'we didn't mean to' is rarely a defense.

Second, the obligation reaches everyone, every U.S. person and business, not just regulated financial institutions.

A fintech that thinks 'we're not a bank, OFAC isn't our problem' is mistaken, and the penalties for getting this wrong can be enormous.

What does OFAC actually require? In essence: don't do business with sanctioned parties, and stop transactions that would. That means you must not deal with persons, entities, or jurisdictions on OFAC's sanctions programs, and when a prohibited transaction appears, you generally must block or reject it and report it to OFAC.

To do that, you screen your customers and their counterparties against OFAC's lists, principally the Specially Designated Nationals list, the S-D-N list, and the broader Consolidated Sanctions list. And you watch jurisdiction-based sanctions too, comprehensive country programs, not only named individuals, because a payment to a sanctioned region can be prohibited even if no named person is involved. The practical upshot for a fintech is that screening has to happen at onboarding and at transaction time, across all the parties money touches.

Here's where fintechs fail. First, screening only the account holder, while ignoring the counterparty, the beneficiary, or data buried in payment fields, so a sanctioned party on the other side of a transfer slips through. Second, mis-tuned matching: names rarely match exactly, so you need fuzzy matching, but set it too loose and you generate endless false hits, set it too tight and you miss real ones, like a transliterated or slightly misspelled name.

Third, stale lists: OFAC updates designations frequently, sometimes with immediate effect, and a fintech that refreshes its lists weekly instead of promptly can transact with someone designated yesterday. Fourth, jurisdiction gaps: failing to use I-P or geolocation and device signals to catch users connecting from comprehensively sanctioned regions. Each of these has shown up in real OFAC enforcement against fintech and crypto firms.

OFAC told us what good looks like. In twenty-nineteen it published 'A Framework for OFAC Compliance Commitments,' which lays out five essential components of a sanctions compliance program. One: senior-management commitment, real ownership from the top.

Two: a sanctions risk assessment, understanding where your products, customers, and geographies expose you. Three: internal controls, the policies, procedures, and screening technology that actually prevent prohibited transactions. Four: testing and auditing, independent checks that the controls work, including testing your screening logic and list coverage.

And five: training, so your people understand the obligation. The fintech takeaway is that sanctions compliance isn't just buying a screening vendor and checking a box; it's a program with the same backbone as your AML program. Build screening into all five components, and you can show OFAC a real program if something ever goes wrong.

Operationally, here's how to do it well at scale. Screen at two points: onboarding, to keep sanctioned parties out, and in real time on transactions, to catch counterparties and intermediaries. Tune your fuzzy matching deliberately, document the logic, and review it, because matching configuration is exactly what testing under the framework is meant to challenge.

Keep your sanctions lists fresh with prompt updates, and have a process for interim and immediate designations rather than a fixed weekly batch. And build a clear playbook for hits: how you investigate a potential match, who decides, when you block versus reject, how you escalate, and how and when you report to OFAC and, where relevant, file the related suspicious activity report. A screen with no decisioning playbook behind it is just an alarm nobody is trained to answer.

Let's lock it in. Sanctions are a separate, strict-liability regime administered by OFAC that applies to every U.S.

person and business, fintech included. You must avoid and stop transactions with sanctioned persons, entities, and jurisdictions by screening customers and counterparties against the S-D-N and Consolidated lists, with well-tuned matching, promptly refreshed lists, and jurisdiction controls. And OFAC's twenty-nineteen Framework tells you to wrap that screening in a real program: management commitment, risk assessment, internal controls, testing and audit, and training.

Self-check: do you screen both sides of a transaction, how fresh are your lists, and could you produce the five framework components on demand? Next, we tackle a rule that trips up almost every payments and crypto fintech: the Travel Rule.
