Citigroup Launches Bitcoin Custody Service for Institutional Clients via Custody+

Citigroup is entering the cryptocurrency space with the launch of its Bitcoin custody service, Custody+, specifically designed for institutional clients. Announced on August 18, 2026, this service represents a significant move by a major banking institution into crypto infrastructure.

The Custody+ platform will enable asset managers and other institutional players to hold Bitcoin alongside traditional assets, streamlining the management of both types of investments. With Citigroup managing approximately $30 trillion in client assets, even a small influx into Bitcoin custody could indicate a notable shift in institutional engagement with cryptocurrencies.

Functionality of Custody+

The platform is designed to handle key management, wallet infrastructure, and safekeeping, relieving institutional clients from the complexities of managing private keys and wallets. Custody+ integrates digital asset holdings with traditional financial services, including custody, settlement, foreign exchange, and cash management, all operating with near-real-time processing capabilities.

Initially, the service will focus solely on Bitcoin, although Citigroup has indicated plans to expand into additional digital assets as demand grows. The development of Custody+ took approximately three years, with hints about its launch surfacing as early as October 2025.

This initiative aligns with Citigroup's broader strategy in digital assets, which now includes services for both tokenized assets and traditional cryptocurrency holdings.

New Developments in Institutional Bitcoin Demand

Fidelity's clients have purchased $134 million worth of Bitcoin in just two days, indicating a resurgence in institutional interest. This buying spree is significant not only for its size but for its rapid accumulation.

The Fidelity Wise Origin Bitcoin Fund (FBTC), launched in January 2024, has become one of the leading funds in the U.S. spot Bitcoin ETF market, alongside BlackRock's iShares Bitcoin Trust (IBIT).

Research published by Fidelity in 2026 suggests that Bitcoin could play a vital role in institutional portfolios, encouraging clients to consider allocations.

Despite the volatile crypto market in 2026, institutional investors are leveraging regulated products like FBTC and IBIT, which may facilitate further regulatory clarity in the future.
