Key Insights:
- Bitcoin custody is scheduled to launch within Citi Custody+ later in 2026.
- Initial support for Bitcoin is targeted toward institutional clients.
- Custody+ integrates liquidity, settlement, asset servicing, and data into a single system.
Citigroup has announced plans to integrate Bitcoin custody into its Custody+ platform later in 2026, beginning with institutional accounts. This initiative houses Bitcoin alongside conventional securities within a unified operating structure, potentially cutting down dependence on fragmented reporting systems and third-party crypto custodians. The timeline was disclosed by Citi on August 18 alongside the rollout of near-real-time custody and settlement capabilities.
While an exact launch date and other supported assets remain unspecified, Bitcoin was trading near $64,700 following the announcement, though Citi did not link the platform release to market price expectations. This latest Bitcoin development builds upon a digital-asset framework that Citi initially revealed in October 2025.
Citi Places Bitcoin Custody Inside Its Custody+ Framework
According to Citi, the service will operate on the bank’s unified digital-asset architecture, delivering traditional and cryptocurrency custody features through one cohesive system. Bitcoin will serve as the initial supported asset, firmly integrating the Citi Bitcoin offering into its established custody operations.
This division currently serves clients across over 100 markets, which includes 62 markets operating on Citi’s proprietary network. Such scale provides the bank with an existing institutional customer base for the upcoming offering, allowing asset managers to keep their Bitcoin with the same institution that oversees their bonds and equities.
Under the model, the bank safeguards the assets directly, sparing clients from managing private keys themselves. Even so, Citi has not yet released specifics regarding fees, insurance coverage, wallet architecture, subcustodians, or client eligibility requirements. These parameters will ultimately determine how the Citi Bitcoin solution measures up against dedicated digital asset providers.
Amit Agarwal, who heads custody for Citi Investor Services, described Custody+ as a multi-year investment in infrastructure designed to streamline client operating frameworks as market dynamics evolve.
Custody+ Brings Real-Time Tools Into One Modular System
Beyond Bitcoin custody, the Custody+ platform consolidates a wide array of post-trade functions. Its toolset encompasses market intelligence, tax processing, cash management, foreign exchange, liquidity, settlement, and asset servicing.
The suite is powered by Single Event Processing technology, which is currently deployed across the bank’s U.S. custody operations. Citi reports that SEP has cut processing durations for voluntary corporate actions by as much as 92%, handling 96% of these events within a two-hour window.
At present, more than 80% of Citi’s total asset-servicing event volume updates in real time. Furthermore, integrated ledgers offer clients comprehensive transaction visibility across all 62 of Citi’s proprietary custody markets.
The platform supplies projected balances for custody transactions, funding instruments, liquidity sweeps, and immediate cash updates. Additionally, Citi Token Services facilitates round-the-clock, nearly instantaneous movement of tokenized deposits in select markets.
Artificial intelligence is also utilized by Citi to accelerate tax documentation handling and drive its Market Guide service, yielding a 70% decrease in tax document processing times. The institution’s Services division channels over $2 billion annually into platform development.
Bitcoin Custody Extends Wall Street Digital Asset Push
Citi’s Bitcoin strategy aligns with a broader industry trend of Wall Street firms expanding into digital assets. BNY rolled out crypto custody services for select U.S. clients back in 2022, while Coinbase and Fidelity Digital Assets also cater to institutional investors.
Traditional financial institutions gained a clearer pathway into Bitcoin custody following the SEC’s withdrawal of Staff Accounting Bulletin 121 in 2025, a guideline that had previously driven up the capital costs for banks holding customer cryptocurrencies.
Morgan Stanley is similarly developing in-house infrastructure for Bitcoin trading and custody. Its head of digital assets noted that the bank is investigating yield products and lending opportunities, though a timeline has not been established.
In a separate collaboration, Citi is partnering with BNY to support the New York Stock Exchange’s proposed tokenized-securities platform. Subject to regulatory approval, the initiative aims to enable blockchain-based trading featuring continuous, 24/7 settlement, with Citi and BNY facilitating fund transfers and tokenized deposits outside regular banking hours.
