Citibank Launches Institutional Bitcoin Custody Under Custody+ Platform
On August 18, 2026, Citibank (NYSE: C) announced that it will introduce institutional-grade Bitcoin custody services later this year as part of its Custody+ offering. This move marks Citibank’s first integration of digital asset custody into its broader institutional asset management ecosystem, blending traditional securities and digital asset safekeeping for a unified client experience.
Citibank highlighted that the Custody+ platform leverages a shared digital asset architecture to bring together cryptocurrency and conventional securities custody. This integration aims to meet growing market demands for extended trading hours and faster settlement processes. Clients will benefit from accessing both crypto and conventional custody services within a single cohesive system, eliminating the need to navigate between separate platforms.
Real-Time Processing Enables Continuous Market Access
A core technological foundation of the custody service is Citibank's Single Event Processing system, which handles over 80% of event flows across global and domestic markets in real time. In the U.S. markets specifically, approximately 96% of auction bids and dividend election events are processed within two hours.
Beyond custody, the platform combines settlement, foreign exchange, liquidity management, tax services, and market data into an integrated solution supporting continuous trading and cross-asset settlement. Citibank’s digital asset strategy is designed to transcend traditional market hours, progressively facilitating a 24/7, year-round trading environment.
In June 2026, Citibank also launched a blockchain-based tokenization project for private company stock depositary receipts. Partnering with Swiss financial infrastructure operator SIX, the initiative provides regulated investors blockchain access to private equity holdings. This allows clients to incorporate private market equity seamlessly within their traditional portfolios, enhancing digitization and liquidity.
Regulatory Clarity Boosts Institutional Digital Asset Services
U.S. Securities and Exchange Commission Chair Paul Atkins confirmed ongoing regulatory efforts in 2026 focusing on on-chain transactions and custody rules to maintain investor protections. The Office of the Comptroller of the Currency (OCC) has authorized national banks to hold certain types of crypto assets under defined conditions for network fee settlement and platform testing, further solidifying compliance frameworks for digital asset custody.
As traditional securities increasingly shift to blockchain platforms, the demand for rapid settlement solutions intensifies. Citibank projects that the market capitalization of digital assets and tokenized securities could surge from roughly $17 billion today to $5.5 trillion by 2030. This growth will underpin token-based liquidity services capable of supporting near-instantaneous capital movements in some markets.
Through Custody+, Citibank aims to deliver a comprehensive custody solution that spans both traditional and digital assets, catering to institutional clients’ needs for seamless 24/7 trading and swift asset settlement. This development reflects the advancing maturity and expansion of the institutional digital asset space.
