Major Wall Street banks are rapidly entering the digital asset custody market, fundamentally reshaping the competitive landscape. According to reports, BNY Mellon, the world's largest custodian with $59.4 trillion in assets under custody, began holding Bitcoin and Ethereum for ETF issuers in 2022 and expanded services to Abu Dhabi in May 2026. State Street, the second-largest custody bank at $51.7 trillion, launched its Digital Asset Platform in January 2026 through partnership with Taurus. Citigroup announced Custody+ on August 18, targeting a live launch before year-end 2026, while Standard Chartered is acquiring Zodia Custody subsidiary to merge with its corporate banking division.
Two critical regulatory changes cleared the path for bank entry in 2025. As reported, the SEC rescinded Staff Accounting Bulletin 121 in January 2025, removing the rule that forced banks to treat client Bitcoin as their own liability on balance sheets. The OCC confirmed through Interpretive Letters 1183 and 1184 that national banks may custody crypto assets without prior approval, eliminating the months-long approval process. The GENIUS Act, signed in July 2025, created new national trust bank charter pathways, with the OCC conditionally granting charters to Circle, Paxos, BitGo, Fidelity Digital Assets, and Ripple by end of 2025.
Crypto-native custodians face significant competitive pressure from traditional banks. According to industry data, Coinbase Custody manages approximately $376 billion in institutional crypto assets and custodies more than 80% of U.S. spot Bitcoin and Ethereum ETF assets. BitGo's assets under custody crossed $90 billion in mid-2025, while the top five crypto-native custodians hold roughly 46% of the global market. Banks enter with structural advantages in hardware security modules and balance sheet strength, while crypto natives maintain advantages in multi-party computation technology and specialized insurance relationships.
A critical protection gap exists in the crypto custody market that could define future competition. As reported, only approximately 1% of the cryptocurrency market by value carries insurance coverage, with the crypto insurance market totaling roughly $1.9 billion in premiums against a total crypto market valued at approximately $2.5 trillion in 2024. Leading custody insurance programs offer between $75 million and $320 million in coverage limits, creating a significant protection gap that neither banks nor crypto natives have fully addressed.
The digital asset custody market is projected to grow significantly, creating opportunities for both traditional banks and crypto-native firms. According to industry estimates, the market is expected to grow from roughly $953 billion in 2026 to more than $4.3 trillion by 2030. Banks are simultaneously building tokenized deposit networks and settlement infrastructure, with JPMorgan, Citigroup, Bank of America, and Wells Fargo constructing a shared tokenized deposit network targeting the first half of 2027. The competitive outcome will likely depend on whether institutional clients prioritize bundled traditional and crypto services at banks or specialized depth from crypto-native platforms.
