Citigroup Services recorded Q4 and full-year 2025 revenue of $21.3 billion, an 8% year-over-year increase, and achieved a 28.6% return on tangible common equity. Net interest income rose 12%, fees grew 6%, deposits climbed 7%, loans expanded 9%, and assets under custody and administration surged 24%.

The division is aggressively investing in technology and AI to improve operations and client service, deploying use cases that reduce document review times from hours to minutes. Key initiatives include Single Event Custody Processing, Citi Payment Express (live in 22 markets handling 40% of flows) and 24/7 clearing used by 300 banks, alongside internal blockchain networks.

Service growth is anchored on deepening relationships with Fortune 500 and Commercial Bank clients, where wallet share gains exceeded 200 basis points in institutional transaction services and securities services and doubled in the Commercial Bank segment. Citigroup achieved an 8% revenue CAGR from 2023-2025 and a 14% CAGR since 2021.

Looking ahead, management expects conventional payment rails and tokenized ecosystems to coexist, investing in interoperability between blockchain and traditional infrastructure. The bank is preparing to commercialize digital asset capabilities globally while navigating regulatory and geopolitical complexities to sustain revenue durability.
