Post-9/11 list growth and bank 'de-risking' (2000s-2010s)
After the September 11 attacks, the SDN List expanded rapidly. Banks, fearing penalties, over-blocked, sometimes dropping whole regions, charities, and money-transfer firms rather than risk a match.
Legitimate customers were cut off, and some remittance channels to poor countries dried up.
Regulators and the World Bank documented the harm of over-compliance, building the case that a bloated list can backfire.
It is the problem Treasury now cites: too many stale names produce false alarms and push banks to avoid legitimate business.
