The bank custody race: who holds America’s Bitcoin

Wall Street did not wake up one morning and decide it liked Bitcoin. It woke up and realized the custody fees were too large to leave on someone else’s balance sheet.

For most of the past decade, holding digital assets for institutions was a job only crypto-native firms would touch. Coinbase built a custody arm. BitGo pioneered multi-signature wallets for institutional clients. Anchorage Digital became the first federally chartered crypto bank. They earned the business because traditional banks either could not or would not hold the keys.

That era is ending. In the span of 18 months, BNY Mellon, State Street, Standard Chartered, U.S. Bank, and now Citigroup have either launched or committed to launching direct crypto custody services. The question is no longer whether banks will hold Bitcoin. It is what happens to the companies that held it first.

The regulatory gates that opened everything

Two regulatory changes made the bank custody wave possible, and both arrived within weeks of each other. Understanding the sequence matters because it explains why the bank entry wave happened in 2025 and 2026 and not before: the barriers were legal and accounting constraints, not technological ones.
