OFAC Screening Frequency

How often a screening tool refreshes its sanctions data, where hourly or real-time syncs prevent the gaps that weekly updates create.

TL;DR

TL;DR: Screening frequency is how often list data refreshes. Hourly or real-time sync is best practice; weekly or monthly updates leave compliance gaps.

Frequency Versus Coverage

Screening frequency is separate from whether you screen at all. It describes how current the underlying data is. You can screen every payment, but if the list behind it is a week old, newly designated parties pass unnoticed and newly delisted parties are wrongly blocked.

Why Stale Data Is a Real Gap

OFAC applies strict liability, so intent is not required, and a stale list does not excuse a violation. Civil penalties start at $356,000 per violation. A designation added after your last sync but before your next payment is exactly the exposure a slow frequency creates.

Frequency in Practice

sanctionsai.dev syncs its screening data hourly, covering 947 OFAC-listed crypto wallets and 19,218 SDN names across 16 jurisdictions. An hourly cadence keeps the gap between an OFAC update and an agent's screening decision small enough to be defensible.

Practical Guidance

• Prefer hourly or real-time sync over weekly exports.
• Verify the sync timestamp in the tool you rely on.
• Re-screen recurring counterparties on each new refresh.
