Artificial intelligence (AI) is redefining the way financial institutions detect and prevent money laundering.
With the United Nations estimating that criminals launder up to $2tn each year — of which only around 2% is detected — traditional anti-money laundering (AML) systems are no longer sufficient. As financial crime tactics evolve, regulators are tightening compliance expectations, and manual, rules-based processes are struggling to keep pace, claims Alessa.
Modern AML solutions are increasingly powered by AI and machine learning (ML), enabling institutions to move from reactive to proactive monitoring. Platforms like Alessa are leading this transformation by helping organisations identify risks faster and more accurately. AI’s ability to process vast data sets, recognise behavioural patterns, and detect anomalies in real time is proving critical to improving efficiency and compliance outcomes.
Traditional AML tools rely heavily on fixed thresholds, often producing a high rate of false positives that waste investigator time. By contrast, AI models can adapt dynamically, learning what constitutes normal behaviour and flagging genuine anomalies. Key benefits include real-time detection of suspicious activity, a reduction of false positives by up to 40%, and context-aware risk modelling that evolves with customer behaviour.
AI’s application within AML spans three main categories. Analytical AI drives advanced pattern recognition and dynamic risk scoring, enhancing investigation accuracy. Generative AI streamlines reporting by summarising documents and pre-filling suspicious activity reports. Meanwhile, agentic AI introduces digital agents that autonomously execute tasks like transaction monitoring, sanctions screening, and Know Your Customer (KYC) refreshes.
Transaction monitoring remains the backbone of AML compliance. As criminals exploit faster payment networks and digital assets, AI allows compliance teams to respond in real time. Alessa’s monitoring tools screen counterparties against sanctions lists, automate investigative workflows, and improve collaboration across teams. This technology not only reduces false positives but also accelerates case resolution.
AI is also revolutionising identity verification and KYC processes. Alessa’s system uses AI to verify identities instantly, screen for politically exposed persons (PEPs), and continuously monitor for changes in customer profiles. Generative AI further enhances these operations by extracting key details from documents and drafting due diligence summaries — significantly cutting down analyst workloads.
The next frontier, agentic AI, takes automation to new levels. These autonomous systems can manage complex compliance tasks with little human intervention. Nasdaq Verafin, for example, launched an agentic AI workforce in 2025 that reduced sanction-screening alerts by over 80%, highlighting the potential productivity gains for compliance teams.
However, as adoption accelerates, governance and ethics remain vital. AI systems must be transparent, explainable, and free from bias. Financial institutions are encouraged to establish robust governance frameworks, maintain high-quality data, and train teams to interpret AI-driven outputs responsibly. Alessa’s guidance emphasises that clean data and regularly updated models are essential to responsible AI implementation.
Looking ahead, AI’s role in AML will only deepen. The RegTech market is projected to surpass $22bn, with blockchain integration, biometric onboarding, and privacy-enhancing technologies becoming standard. Increasing cross-border cooperation and stricter beneficial ownership transparency will also define the landscape.
To prepare, firms should assess current systems, identify the most impactful AI use cases, and prioritise governance and data quality. By adopting a balanced mix of analytical, generative, and agentic AI, institutions can modernise compliance operations, reduce risk exposure, and meet evolving regulatory standards.
AI-driven AML platforms like Alessa demonstrate that innovation and integrity can coexist. Through responsible deployment, financial institutions can not only safeguard their systems but also enhance trust and resilience across the global financial ecosystem.
