Citi Used AI to Shrink a 60-Minute Document Review to 15 Minutes

Banks have spent years launching artificial intelligence (AI) chatbots and virtual assistants. Citigroup’s latest deployment is less visible and more valuable: an AI document-processing system that compresses account opening review time from over an hour to 15 minutes.

Tim Ryan, the bank’s head of technology, told Reuters in April that the improvement is part of a broader push to automate compliance-heavy workflows across the institution.

The use case is one of roughly 50 processes the bank has flagged for automation, with client and employee onboarding and know-your-customer (KYC) compliance among the first in line. Ryan told Reuters the same tools compressing review times are also automating coding, testing and legacy system migration.

Why Account Opening Is the Right Problem

Account opening sits at the intersection of every operational bottleneck a large bank carries. It requires document collection, identity verification, sanctions screening, KYC checks and data entry across systems that rarely communicate cleanly. Manual review doesn’t just slow the process. It introduces errors, creates compliance exposure and consumes staff time that could be better used elsewhere.

Ryan told Reuters Citi has identified roughly 50 critical internal processes for review and automation. Client and employee onboarding are among the first. The bank’s tech workforce now numbers around 50,000 people, he said, with more software engineers hired as it shifts away from contractors.

What the 15 Minutes Actually Means

The 75% reduction in review time isn’t a one-account result. The services division handles institutional and corporate clients, where documentation requirements are dense and volumes are high. Citi’s annual report detailed that the bank has empowered more than 182,000 employees with proprietary AI tools and provided 30,000 developers with AI tools generating approximately 100,000 hours of weekly capacity.

Faster review means earlier revenue recognition on new client relationships, fewer errors from manual data entry and compliance staff spending less time on routine document checks. Ryan told Reuters the bank plans to use AI to migrate data from legacy systems, automate coding and test more and faster. Account opening is the use case Citi chose to disclose. The list of 50 targeted processes suggests the ambition runs further.

PYMNTS Intelligence found that 85% of financial services firms are increasing AI budgets over the next 12 months, with productivity and efficiency gains cited as the top justification by 65%. Yet AI adoption for KYC and identity verification across the industry sits at just 20%, the report found, meaning the gap Citi is closing is still wide open at most institutions.

Last month, PYMNTS reported that financial institutions are adopting AI more deeply, with emphasis on back-office functions where data is structured, outcomes are measurable and the return on investment is easier to quantify.
