The bank had been under regulatory scrutiny for three years following an examination that found their AML monitoring covered only 22% of transaction volume in real time, with the remainder processed in overnight batch cycles. The regulator required full real-time coverage as a condition of continued operation in two key markets. Achieving this with their existing infrastructure would have required a $28M capital investment that the board had deferred.
LLM reasoning deployed across the full 14 million daily transaction stream. Every transaction was scored for AML risk indicators, with structured compliance records and reasoning traces generated for the full audit trail.
"Three years of regulatory pressure resolved in eight weeks. The cost equation had simply never worked before. Now it does."

The subsequent regulatory examination found full compliance with all real-time monitoring requirements. Examiners specifically noted the quality of the audit trail — LLM-generated reasoning traces for each flagged transaction provided a level of documentation that exceeded the standard. Two previously undetected structuring patterns were identified and reported in the first 30 days of full coverage.
