Citi Bitcoin Custody Launch Targets Institutional Clients in 2026

TLDR:

• Citi Bitcoin custody will launch later in 2026, giving institutional clients access to Bitcoin and traditional asset safekeeping through one framework.
• The Custody+ platform will connect custody with faster settlement, foreign exchange, and cash management services for Citi institutional clients.
• Citi says over 80% of custody event volume now processes in real time, while 96% of U.S. voluntary events finish within two hours.
• The SEC rescinded SAB 121 guidance in 2025, removing an accounting obstacle while retaining disclosure and risk assessment requirements.

Citigroup plans to launch Citi Bitcoin custody later in 2026 through its new Custody+ platform. The service will let institutional clients keep Bitcoin beside stocks, bonds, cash, and other traditional holdings. Citi has not announced a specific launch date or detailed its custody fees. 

Bitcoin traded near $64,305 on Tuesday, gaining about 1.2% during the session. The custody announcement does not directly explain that price move. Still, it adds another regulated banking option for institutions seeking digital asset exposure. Citi will introduce Bitcoin first. It is now developing faster custody, settlement, foreign exchange, and cash services for global investment firms.

Citi Bitcoin Custody Brings Crypto Into One Framework

Citi unveiled Custody+ on Tuesday as a modular suite for institutional asset servicing. Through Citi Bitcoin custody, clients could use one banking relationship for digital and traditional assets. That structure may reduce separate accounts with crypto-native custodians. It may simplify reporting, oversight, cash movement, and controls for investment firms.

Citi says its custody operation serves clients across more than 100 markets. Its proprietary network covers 62 markets, giving direct control across much of that footprint. The Custody+ platform builds on those systems.

Amit Agarwal, Citi Investor Services head of custody, described the project as a multiyear infrastructure commitment. Agarwal called Custody+ “the product of a multi-year commitment.” He said the infrastructure matches “the speed of our clients’ strategies.”

The launch puts Citi Bitcoin custody into a market served by specialized firms and banks. BNY launched U.S. digital asset custody in 2022. Its service supported Bitcoin and Ether for clients. Fidelity Digital Assets and Coinbase also compete for institutional business. U.S. Bank restarted its Bitcoin custody service in 2025 after pausing the program.

Citi Bitcoin custody could appeal to institutions preferring established bank controls and consolidated service relationships. Clients will examine security, asset segregation, insurance, jurisdictional coverage, and operational responsibility. They may compare fees, access rules, reporting tools, and withdrawal controls. Citi has not disclosed terms.

Custody+ Speeds Settlement Across Institutional Markets

Citi is pairing institutional Bitcoin custody with a broader overhaul of post-trade operations. Its Single Event Processing technology routes many asset-servicing tasks through one system. That approach replaces multistep handling across separate processes and internal platforms.

The bank says more than 80% of event volume now processes in real time. U.S. voluntary events take up to 92% less processing time. Moreover, 96% finish within two hours. These figures cover current custody operations, rather than the forthcoming Bitcoin service.

The Custody+ platform also combines near-real-time settlement, foreign exchange, and cash management features. For institutional users, faster processing can reduce delays between asset decisions and related cash movements. Continuous service also fits crypto markets, which trade every day without traditional exchange hours.

Citi Bitcoin custody follows a major U.S. accounting change. The SEC issued Staff Accounting Bulletin 122 in January 2025. The bulletin rescinded crypto safeguarding guidance under SAB 121. The former guidance addressed balance-sheet accounting for obligations to safeguard customer crypto assets.

Its withdrawal removed one accounting hurdle for banks considering institutional Bitcoin custody. The SEC still requires companies to assess possible loss liabilities and provide relevant disclosures. Banks also face anti-money laundering, cybersecurity, capital, and operational requirements.

Citi has not said if it will hold private keys directly or use a subcustodian. The bank has not disclosed supported account structures, withdrawal processes, insurance terms, or geographic availability. Those details will shape client comparisons between the Custody+ platform and existing providers.

Citi Bitcoin custody starts with Bitcoin, but the bank has not named additional supported assets. The planned rollout links crypto safekeeping with Citi’s global custody network and wider real-time processing program.
