Citigroup's institutional services division launched Custody+, a real-time settlement platform for digital assets, on August 18. Bitcoin custody services on the same platform will arrive later in 2026.
The platform executes trades and settles holdings instantly rather than on T+1 or longer cycles standard in traditional finance. Citi positions the service for institutional clients moving digital assets across multiple venues without delay between execution and final ownership transfer.
Custody+ enters a market where established players like Fidelity Digital Assets, Kraken Institutional, and Coinbase Prime already operate custody and settlement infrastructure. Fidelity began offering Bitcoin custody to institutions in 2021. Coinbase Prime launched in 2018 with real-time settlement as a core feature. The addition of Bitcoin custody to Citi's platform later this year will expand the bank's existing digital asset services, which have grown as institutional allocators enter crypto markets.
Citi Investor Services, which runs the custody business, has increased its digital asset operations since 2020 when it began settling USD Coin transactions for clients. The bank's move into Bitcoin custody comes as institutional asset managers and hedge funds seek custody from a systemically important financial institution with established regulatory oversight.
The real-time settlement mechanism differs from traditional custody arrangements where trades clear over multiple days. Blockchain-based settlement allows Citi to record asset transfers on distributed ledgers instantly, eliminating counterparty risk during the settlement window. This speed reduces operational friction for large trades and allows institutions to deploy capital more efficiently.
Citi's Bitcoin custody launch comes as other major financial institutions expand digital asset services. BlackRock's iShares Bitcoin ETF, which launched in January 2024, has drawn substantial institutional capital and created demand for qualified custodians. The SEC approved spot Bitcoin ETFs for U.S. markets in that period, accelerating institutional adoption.
The timing and technical specifications of Citi's Bitcoin custody rollout will determine whether the bank captures significant institutional flows. Citi has 220 million customer accounts and operates in over 160 countries; its scale and regulatory standing position it to handle custody for large institutional allocators if the Bitcoin service launches without operational delays. The key measure will be the total Bitcoin assets Citi holds under custody by year-end 2026 and whether institutional clients migrate balances from existing custodians.
