85% Reduction inFraud Losses
How Global Trust Bank transformed fraud prevention with AI, saving $47M annually while improving customer experience
About Global Trust Bank
Global Trust Bank is one of the world's largest financial institutions, serving over 70 million customers across 42 countries. With $2.3 trillion in assets under management, the bank processes more than 50 million transactions daily through its extensive network of branches, ATMs, and digital channels.
As digital banking adoption accelerated, so did the sophistication of fraud attacks. The bank faced an existential threat: traditional rule-based fraud detection systems couldn't keep pace with AI-powered criminal networks. They needed a revolutionary approach to protect customers and maintain trust in an increasingly digital world.
The Challenge
Sophisticated fraudsters were winning the arms race against traditional detection methods
Sophisticated Fraud Schemes
Criminals using AI and advanced techniques to evade traditional rule-based systems
High False Positive Rates

Executive Perspectives
Hear from the leaders who championed this transformation
“The AI doesn't just catch fraud - it predicts it. We're now stopping attacks before they happen, not cleaning up afterward. The 85% reduction in losses speaks for itself, but the real win is customer trust.”
“False positives were killing our customer experience. The AI's precision means we block 62% fewer legitimate transactions while catching more actual fraud. Customer complaints dropped 78%.”
“The explainable AI feature is game-changing for compliance. Regulators love that we can show exactly why each decision was made. We went from constant scrutiny to being held up as a best practice example.”
Overcoming Implementation Challenges
Legacy System Integration
The bank's 30-year-old core banking system initially couldn't handle real-time AI processing.
Solution:
Built a microservices layer that acts as a bridge, allowing AI to process transactions without disrupting core systems. This approach enabled phased migration while maintaining 100% uptime.
Team Resistance
Fraud analysts feared AI would replace their jobs, leading to initial pushback.
Solution:
Reframed AI as an “augmentation tool” that handles routine cases, freeing analysts to focus on complex investigations. Provided extensive training and created new roles in AI oversight and tuning.
Regulatory Compliance
Regulators in 42 countries had concerns about AI “black box” decision-making.
Solution:
Implemented explainable AI features that provide clear reasoning for every decision. Created comprehensive audit trails and worked closely with regulators to establish new AI governance frameworks.
Key Lessons Learned
Critical insights for successful AI fraud prevention
Data Quality is Paramount
Investing in clean, comprehensive data paid dividends in model accuracy
Human-AI Collaboration
AI augments but doesn't replace expert fraud investigators' intuition
Continuous Learning Essential
Fraud evolves daily - models must adapt just as quickly
Transparency Builds Trust
Explainable AI crucial for regulatory compliance and team adoption
