USE CASE 3 - Regulatory compliance

Executive summary

Generative-AI (GenAI) — particularly “ChatGPT-class” large-language models (LLMs) — are reshaping regulatory compliance and risk management in banking and financial services. Instead of being experimental or marginal, these tools are increasingly becoming central to compliance workflows: summarising regulations, monitoring policy changes, automating compliance reporting, assisting with KYC/AML, and generating audit-ready documentation.

That said, the widespread adoption also introduces significant challenges — data privacy, auditability, explainability, bias, governance. Regulators and institutions must adjust strategies and controls accordingly.

This whitepaper collates empirical data, industry-level surveys, research studies and practitioner guidance to:

  • Show where and how GenAI is being used right now

  • Examine the trade-offs and risks associated with reliance on LLMs for compliance

  • Propose a governance framework — how institutions can deploy GenAI for compliance while maintaining auditability, accountability, and regulatory readiness

1. Where GenAI is already used in compliance & risk

🔹 Core use cases

Generative AI is being leveraged in multiple compliance domain areas:

  • Regulatory document analysis & summarization: GenAI tools scan regulatory updates — laws, circulars, guidelines — compare them with prior versions, highlight changes, and summarise their implications for internal policies and procedures. This dramatically reduces the manual time needed for policy-review cycles.

  • Internal policy-to-regulation mapping: By comparing internal policies with external regulation, GenAI identifies gaps, misalignments, or contradictions (for example, when regulation changes). This helps keep internal governance frameworks up to date.

  • Compliance reporting & documentation drafting: Regulated institutions must submit periodic reports (e.g. risk reports, capital adequacy, incident reports, AML filings). GenAI can draft or pre-populate regulatory reports, structure them, and reduce the burden on compliance teams.

  • Transaction monitoring, AML & financial-crime risk detection: Beyond number-based analytics, GenAI can analyse textual data associated with transactions — e.g. narrative fields, free-text descriptions, context — to detect suspicious activity, generate suspicious activity reports, and assign risk ratings based on KYC changes.

  • Credit-risk and credit documentation processes: GenAI can summarise customer financial data, analyse credit risk factors, generate risk assessments, and even draft credit memos or contracts after decisions are made.

  • Real-time regulatory intelligence & risk-intelligence centers: According to consultancies like McKinsey, banks are exploring “gen-AI-powered risk intelligence centers” that continuously ingest market data, regulatory changes, counterparty data, and internal metrics — offering dynamic risk assessments, policy-updates, stress-testing, and transparency across first and second lines of defense.

In essence, GenAI is functioning as a “virtual compliance expert,” able to undertake many of the heavy-lifting tasks that used to require large teams of compliance analysts.

Adoption trend and scale

According to a synthesis of recent surveys and industry reports:

  • ~ 62% of compliance teams (in finance) now use AI in their compliance workflows — with 36% using AI across compliance and investigations, and 26% using AI exclusively for compliance tasks.

  • Among firms that use AI, ~ 52% employ public enterprise GenAI tools (e.g. ChatGPT-class), and ~ 75% are actively exploring AI adoption for compliance-related functions.

  • Around 53% of professionals (permitted to use ChatGPT) reportedly rely on it for “adherence guidance” — i.e. informal regulatory interpretation or compliance help.

These numbers suggest that GenAI has already moved well beyond pilot projects: it is now a mainstream tool inside many compliance units.

2. What GenAI brings: opportunities & efficiency gains

Using GenAI for compliance and risk offers several important advantages:

  • Speed and scalability — Document-heavy tasks (policy reviews, regulatory updates, large transaction logs) that once took weeks or months can now be processed in hours.

  • Consistency and standardisation — AI-generated reports, summaries, and compliance documents tend to follow uniform formats and language. This helps reduce errors due to manual drafting and ensures compliance outputs are standardized across business units.

  • Proactive risk management (“shift left” approach) — As per McKinsey, GenAI can push risk detection and compliance alignment earlier in the business cycle, rather than catching issues after manual reviews.

  • Resource reallocation — By automating routine tasks, compliance and risk professionals can shift focus toward strategic efforts: emerging-risk analysis, product-compliance reviews, governance frameworks, supervisory readiness.

  • Improved AML and fraud detection through richer context analysis — Traditional rule-based AML systems often rely on numeric thresholds or simple heuristics; but generative AI can parse narrative data, detect suspicious patterns, and generate explanations and risk narratives, improving detection quality.

Overall, GenAI helps compliance functions become more agile, adaptive, and resilient — a critical advantage given the accelerating pace of regulatory change globally.

3. Risks, limitations, and compliance challenges

Despite its promise, using GenAI in regulated finance raises serious risks and caveats.

Key challenges

  • Explainability & auditability: LLMs (like ChatGPT) typically operate as black boxes. In compliance environments, regulators require audit trails — why a certain decision was made, which rules were applied, etc. Without logging reasoning or decision-chains, AI-generated outputs may not meet regulatory standards.

  • Data privacy & confidentiality risks: Inputting sensitive customer data, transaction details, or internal documents into public or insufficiently secured AI services can breach data-protection regulations (e.g. GDPR), especially if data is reused for model training or is stored beyond its intended purpose.

  • Bias, fairness & discriminatory risk: Since LLMs are trained on large internet-sourced data, they may carry biases; that’s particularly dangerous in functions like credit decisioning or risk scoring, where biased outputs may lead to discriminatory decisions.

  • Regulatory and systemic risk concentration: If many banks rely on the same external models/providers, errors or flaws in those models could lead to systemic compliance failures — which could endanger financial stability.

  • Model risk & governance gaps: Without robust oversight, model validation, and governance structures, the use of GenAI may create more regulatory risk than it mitigates. As noted in a 2025 legal-regulatory analysis, many jurisdictions lack mature rules dealing specifically with AI in financial services.

  • Shadow-AI usage and uncontrolled adoption: Despite formal governance, many employees may start using public tools unofficially — a phenomenon known as “shadow AI”. That increases data-leak risk, compliance blind spots, and regulatory exposure.

In short: while GenAI offers huge efficiency gains, blindly deploying it without strong controls may undermine compliance integrity and create new risks.

4. Toward a “Regulator-Ready” AI Governance Framework

To harness the benefits while controlling the risks, financial institutions should treat GenAI deployment as a major governance project — essentially building a “compliance-AI stack”. Below is a proposed framework:

Key building blocks

  1. Data governance & protection

    • Strict data-classification: identify what data can be processed by AI tools (public regulation texts, generic policy templates) vs what is restricted (customer PII, transaction-level data).

    • Use enterprise-grade / on-premise or secure-cloud GenAI tools — avoid public free services for sensitive data.

    • Maintain audit logs: record inputs, outputs, model versions, users, timestamps.

  2. Explainability & audit-trail design

    • Use retrieval-augmented generation (RAG) architectures with traceable sources and version control. This helps anchor model outputs to specific regulatory references rather than opaque “model reasoning.” (e.g. frameworks like FinSage built for financial filings)

    • Maintain human-in-the-loop review for critical decisions — especially in AML, credit risk, regulatory reporting.

  3. Bias testing & fairness controls

    • Evaluate LLM outputs for signs of systematic bias.

    • Use diverse, representative data sets, and apply fairness / bias-mitigation techniques.

  4. Governance & compliance oversight

    • Establish a compliance-AI steering committee (risk, legal, compliance, data-privacy leads).

    • Define clear policies: when AI may be used, by whom, for what tasks, and under which controls.

    • Regular audits and model validation.

  5. Regulatory liaison & continuous monitoring

    • Engage with regulators or supervisory bodies proactively. Given rapid model evolution, regulatory frameworks are still catching up, and oversight regimes must adapt. Studies warn of systemic risk if many institutions rely on similar AI tools.

    • Maintain flexibility to update models, processes, and governance as regulations or model architectures change.

  6. Fallback & human-in-the-loop for sensitive decisions

    • For high-risk decisions (e.g. AML flags, credit approvals, sanctions screening), ensure AI outputs are reviewed by trained compliance officers.

    • Use AI as decision-support, not decision-making final authority.

5. Recommendations & Strategic Considerations

Based on the evidence and trade-offs, here are strategic recommendations for financial institutions considering or expanding GenAI-based compliance:

  • Begin with low-risk, high-value use cases: e.g. regulatory-text summarisation, policy-update monitoring, internal policy drafting — where data sensitivity is lower, and risk of audit/regulatory backlash is minimal.

  • Pilot governed AI-compliance copilots: Build retrieval-augmented, traceable assistants (“virtual compliance experts”) that link outputs to source regulations and internal policy cross-references.

  • Institutionalize AI governance: Create dedicated AI governance teams / steering committees combining compliance, risk, legal and data-privacy stakeholders.

  • Educate staff & manage ‘shadow-AI’ risk: Enforce clear policies about what data can/cannot be input into AI tools. Provide approved AI platforms if productivity gains are real — to avoid rogue usage outside compliance.

  • Monitor regulatory developments: The regulatory landscape is still evolving (especially in the UK/EU). Maintain flexibility and readiness to adjust as legal frameworks catch up.

Conclusion

Generative AI represents a paradigm shift in financial compliance and risk management. Its ability to analyse complex regulations, digest huge volumes of data, automate repetitive tasks, and deliver rapid compliance outputs is transforming how banks and financial institutions operate.

Yet with great power comes great responsibility. Without robust governance, data protection, explainability and human oversight, GenAI can introduce as many risks as it solves.

Forward-looking organisations will treat AI not as a “nice-to-have efficiency booster,” but as a core compliance infrastructure — regulated, audited, and built for trust. The winners will be those who strike the right balance between innovation and prudence.

LLM-Driven Fraud Detection in Banking: How ChatGPT-Class Systems Transform Anomaly Analysis & Investigation Workflows (2025)

Executive Summary

Financial institutions worldwide are under intensifying pressure to counter increasingly sophisticated fraud schemes—ranging from transaction-pattern anomalies to identity theft, mule accounts, synthetic fraud, account takeovers, and real-time social-engineering attacks.

Traditional machine-learning fraud systems remain effective for high-volume anomaly detection but lack explainability, contextual reasoning, and human-readable narratives. This is the gap where ChatGPT-style Large Language Models (LLMs) are becoming central to fraud teams.

Across industry, surveys and research show:

  • 73% of financial institutions use AI for fraud detection (IBM, ECB sources).

  • 90% leverage AI to accelerate fraud investigations and detect new fraud patterns in real time.

  • 71% of banks have already implemented or soft-launched GenAI solutions, with fraud and risk among the top three workloads.

This whitepaper synthesizes insights from industry research, academic reviews, and regulatory analyses to explain how LLMs elevate fraud detection systems—especially in anomaly analysis, investigator workflows, and narrative generation.

1. Introduction: The Shift Toward AI-Enhanced Fraud Detection

Fraud in financial services has become increasingly pattern-driven, multi-channel, and behavioural, making rules-based systems insufficient.

The reviewed articles converge on three realities:

  1. Fraud operations have become too complex for static rules or human triage alone.

  2. AI is already embedded in major banks’ fraud infrastructure.

  3. LLMs now serve as the cognitive interface between ML models and investigators, making decisions more transparent and faster to act upon.

ChatGPT-class models are not replacing fraud scoring engines—they are augmenting them by:

  • Explaining anomalies

  • Summarizing cases

  • Linking cross-account behaviour

  • Drafting SAR/STR narratives

  • Surfacing hidden patterns across unstructured logs

This is why the financial industry is rapidly adopting them.

2. Current Landscape of AI in Fraud Detection

2.1 AI Adoption Across Financial Institutions

Based on IBM, ECB, and systematic reviews, AI adoption is now:

  • Mainstream in transaction-monitoring systems

  • Expanding into behavioural biometrics

  • Integrated with AML for unified fraud-risk frameworks

The literature notes that AI’s strengths include:

  • Real-time processing of millions of events

  • Pattern detection that adapts to new fraud strategies

  • Multi-source data ingestion (transactions, devices, user behaviour, session analytics)

2.2 Drivers Behind AI Adoption

Across regions (UAE, Qatar, U.S., EU), banks adopt AI for:

  • Speed: Faster alert triage, especially during peaks

  • Accuracy: Lower false-positives reduce investigator fatigue

  • Scalability: Handling exponential transaction growth

  • Regulatory pressure: Expectation of modern surveillance systems

But despite its power, AI alone still leaves interpretation gaps—and this is where LLMs enter.

3. Rise of LLMs in Fraud Detection

3.1 Why LLMs are Ideal for Fraud Workflows

Based on Taktile, InvestGlass, and SSRN findings, LLMs solve a long-standing issue in fraud operations:

Traditional ML detects fraud — LLMs explain fraud.

LLMs enhance workflows through:

  • Natural-language summaries of suspicious patterns

  • Cross-case linking (e.g., “These 4 accounts share the same device signature”)

  • Contextual reasoning across structured + unstructured logs

  • Conversational querying (“Why did model M42 flag this account?”)

  • Drafting SAR/STR compliance reports

  • Auto-generating investigator notes

This dramatically reduces investigation time.

4. Techniques & Approaches in AI/LLM-Driven Fraud Detection

A cross-study synthesis from arXiv, IJSRA, ECB, and IBM reveals three major layers:

4.1 Layer 1 — Core Machine Learning Detection Models

(Traditional AI foundation)

  • Supervised learning (XGBoost, LightGBM, CatBoost)

  • Unsupervised anomaly detection (Autoencoders, Isolation Forest)

  • Neural sequence models for transaction timelines

  • Behavioural biometrics (session velocity, mouse patterns, device fingerprinting)

These models generate the initial detection signals, but cannot explain themselves.

4.2 Layer 2 — LLM “Cognition & Explanation Layer”

(Where ChatGPT-class models shine)

LLMs interpret detected anomalies and add meaning by:

  1. Reading transaction histories

  2. Detecting suspicious chains of events

  3. Explaining why behaviour deviates from normal patterns

  4. Generating next-step recommendations for investigators

  5. Producing narrative summaries for audit/regulatory teams

This “interpretation layer” is the missing link in many current systems.

4.3 Layer 3 — Investigator Copilot Interfaces

Articles describe emerging interfaces such as:

  • Chat-based investigation consoles

  • Fraud-agent copilots with search + summarization

  • Automated SAR/STR drafting modules

  • Interactive timelines with LLM-generated annotations

Banks are shifting from dashboards → copilots.

5. Regulatory, Ethical & Operational Considerations

Research (ECB, UAE/Qatar academic studies) identifies the major constraints:

5.1 Transparency and Explainability

Regulators demand “model explainability.”
LLMs help satisfy this by:

  • Converting anomalies into explainable narratives

  • Clarifying decision paths

  • Highlighting risk-factors contributing to fraud scores

5.2 Fairness & Bias

Studies outline risks when AI models:

  • Over-flag certain demographics

  • Learn biases from historical fraud labels

LLMs must be trained and governed with strong guardrails.

5.3 Data Privacy & Security

LLMs can only operate with:

  • Encrypted context

  • Strict data-minimisation

  • Region-specific compliance (GDPR, MAS TRM, RBI norms)

5.4 Operational Reliability

Banks must mitigate:

  • Hallucinations

  • Misinterpretation of fraudulent vs legitimate customer behaviour

  • Over-reliance on AI narratives without human review

Most articles recommend “AI + human” hybrid investigation models.

6. Challenges in Deploying LLM-Driven Fraud Systems

Across articles, the main challenges are:

  1. Integration with legacy fraud engines

  2. High governance requirements

  3. Latency constraints in real-time fraud systems

  4. Need for secure on-prem or VPC-hosted LLMs

  5. Lack of labelled datasets for fine-tuning

  6. Risk of regulatory non-compliance without explanation layers

LLMs solve many—but not all—of these.

7. Future Outlook (2025–2028)

All sources predict accelerating adoption with three big shifts:

7.1 Fraud Investigators Will Use AI First, Then Act

LLM copilots become the default entry point for fraud analysts.

7.2 Unified AML + Fraud + Risk Copilots

Banks will shift away from siloed platforms and toward unified GenAI copilots.

7.3 Agentic AI in Fraud Workflows

Next-generation systems will:

  • Pull evidence from multiple systems

  • Cross-reference case history

  • Suggest optimal action

  • Create audit trails automatically

7.4 Multi-modal Fraud Detection

Future LLMs will analyze:

  • Voice phishing calls

  • Screenshots

  • Video KYC

  • Biometrics

  • Behavioural telemetry

This makes fraud harder for attackers and easier for banks.

Conclusion

Fraud detection is one of the highest-ROI applications of AI and LLMs in financial services.
The existing ML layer is now enhanced by a new LLM cognitive layer, enabling deeper reasoning, faster investigations, and far more interpretable outputs.

Banks that combine:

  • ML anomaly detection

  • LLM-based explanation + workflow automation

  • Regulatory-grade transparency

…will lead the next generation of fraud-resilient financial infrastructure.
