AI Powers Efficiency Gains at Citigroup

Citigroup is reporting significant operational improvements through the deployment of artificial intelligence across multiple functions. The bank has already automated 50 key processes and aims to transform many more, with initial results showing substantial time savings.

One notable success: AI-powered document review for account openings in Citi’s U.S. services division now takes just 15 minutes – a reduction from the previous hour-and-15-minute timeframe. This represents a 75% improvement in processing speed.

Strategic Tech Investments Yielding Results

The bank’s technology investments have enabled these gains, with Citi increasing its full-time tech workforce to approximately 50,000 employees while reducing reliance on contractors from 50% to 20% over the past year. According to Head of Technology and Business Enablement Tim Ryan, “We still have legacy systems, but after the tech investments we’ve made, we are in a much better place.”

Beyond account openings, AI is being applied to client onboarding, employee onboarding, KYC processes, data migration from older systems, and even automated coding. The bank has also rolled out prompt training programs where employees have already input over 6.5 million prompts, further optimizing workflows.

Broader Industry Trend Toward AI Adoption

Citigroup’s experience aligns with a wider trend in financial services, as institutions increasingly invest in AI and cloud infrastructure to combat fraud and improve efficiency. A recent PYMNTS Intelligence report found that banks are rapidly adopting agentic AI systems across critical functions like compliance, risk management, and payments.

Ryan highlighted in a LinkedIn post that by the end of 2025, over 182,000 Citi employees across 84 countries will be using the bank’s AI tools – demonstrating a comprehensive enterprise-wide implementation.
