Citigroup (NYSE: C) has unveiled Custody+, a new modular suite of near- and real-time custody services designed to help institutional clients operate in an environment of continuous markets, shorter settlement cycles, and growing reliance on technology and artificial intelligence.
The launch, announced by Citi Investor Services, coincides with the completion of the U.S. rollout of the bank’s patented Single Event Processing (SEP) technology, marking a key step in modernizing its custody infrastructure.
Custody+ moves away from a traditional, one-size-fits-all custody model toward a flexible ecosystem of solutions that clients can tailor to their specific workflows and operating needs.
Citi’s custody operations already serve clients across more than 100 markets, including 62 where the bank maintains its own proprietary network.
The platform aims to provide continuous access, greater transparency, and reduced operational friction as market structures evolve.
A core element of the suite focuses on speed and certainty.
Through SEP technology, asset servicing transactions now flow through a single integrated process across Citi’s global and domestic systems.
The US implementation has cut processing times for voluntary corporate actions by as much as 92 percent, with 96 percent of those U.S. events completed in under two hours.
More than 80 percent of Citi’s overall event volume is now handled in real time. Instant settlement capabilities further support this by linking instructions end-to-end to final settlement at central securities depositories, giving clients clear visibility via integrated ledgers and real-time data in the bank’s proprietary markets.
On-demand foreign exchange tools add flexibility, offering transparent pricing, automated hedging options, and real-time execution to help manage liquidity during the settlement process.
Intelligence and control features round out the offering. Real-time cash and liquidity tools provide instant position updates, sweeping capabilities, funding support, and projections.
Citi Token Services already enables near-instant movement of tokenized deposits on a 24/7 basis in selected markets.
AI-driven tax processing has shortened documentation times by up to 70 percent, improving outcomes.
An enhanced AI-powered Market Guide platform delivers localized insights on regulations and operational changes across more than 100 locations, while cloud and API access allow clients to feed data into their own analytics and models.
Custody+ will support diverse operating models, including digital asset custody.
Citi plans to introduce this service later in 2026, beginning with Bitcoin.
Built on the bank’s common digital asset architecture, it will let clients access both traditional securities and crypto custody within the same framework for a unified experience.
White-label capabilities will also enable other institutions to leverage Citi’s infrastructure for transaction initiation, workflows, reporting, and market information.
Chris Cox, Head of Investor Services at Citi, noted that the Services business invests more than $2 billion annually in its platform strategy emphasizing speed, scale, and availability.
Custody+ exemplifies efforts to remove latency for clients who need precision and continuous access.
Amit Agarwal, Head of Custody at Citi Investor Services, described the suite as the result of multi-year work to align infrastructure with the pace of client strategies and to simplify operations amid industry transformation.
Custody+ positions Citi to support institutional investors navigating faster, always-on markets by combining real-time processing, data-driven tools, and flexible infrastructure—including upcoming digital asset support—into one adaptable platform.
