The institutional digital asset custody market crossed $1 trillion in assets under safekeeping in 2026, triggering a land-grab among global systemically important banks (G-SIBs), crypto-native custodians, and newly chartered trust companies. Standard Chartered's May 18 announcement that it will absorb subsidiary Zodia Custody into its Financing and Securities Services division — two weeks after taking a stake in crypto market-maker GSR at a $1 billion valuation — represents the most aggressive digital asset infrastructure buildout by any G-SIB to date.
The catalyst: the SEC's January 2025 rescission of Staff Accounting Bulletin 121 (SAB 121), which had forced custodians to record client crypto holdings as on-balance-sheet liabilities. With that constraint removed, eleven companies filed for OCC national trust bank charters in 83 days between December 2025 and March 2026 — including Morgan Stanley, Coinbase, Circle, Ripple, BitGo, Paxos, Fidelity Digital Assets, and Crypto.com. The result is a structural overhaul of who holds, settles, and administers digital assets, with fee-revenue implications running into the billions.
On January 23, 2025, the SEC rescinded Staff Accounting Bulletin 121 through the issuance of SAB 122. The original rule, enacted in March 2022, required crypto custodians to record digital assets held for customers as liabilities on their balance sheets. For banks subject to Basel III capital requirements, this made custody economically prohibitive — every dollar of client crypto assets demanded a corresponding capital charge.
SAB 122 replaced the blanket liability requirement with a principles-based assessment: custodians must now evaluate whether to recognize a liability based on the specific risk characteristics of their custody arrangements. In practice, this means banks can hold client crypto off-balance-sheet under standard custodial accounting, the same treatment applied to equities, bonds, and other traditional securities held in custody.
The timing proved significant. By late 2025, the OCC under Comptroller Jonathan Gould had already signaled an open-door posture toward crypto-related charter applications. The combined effect of SAB 122 and OCC receptivity created a regulatory window that banks and fintechs moved to exploit within weeks.
Beginning in December 2025, the OCC received a wave of national trust bank charter applications from digital asset firms. According to FinTech Weekly, eleven companies filed in a span of 83 days:
An amended OCC rule that took effect April 1, 2026, clarified that non-fiduciary custody accounts — the specific structure crypto firms require — were always authorized activities for national trust banks. This retroactive clarification removed lingering legal ambiguity from the charter applications.
The conditional approvals are not final operating licenses. Applicants must build out compliance infrastructure, hire staff, pass regulatory reviews, and demonstrate adequate risk management and anti-money-laundering controls before receiving full charters. However, the pace of approvals — five in a single batch, with additional approvals on roughly monthly cycles — is without precedent in OCC history for a single asset class.
The charter rush is only half the picture. The world's largest custody banks are building parallel infrastructure:
BNY Mellon — the world's largest custodian with $59.4 trillion in assets under custody and administration — launched its U.S. digital asset custody platform in October 2022 for Bitcoin and Ethereum. In May 2026, BNY expanded to Abu Dhabi, extending services to Middle Eastern institutional clients. Its Treasury Services division processes approximately $2.5 trillion in daily payments.
State Street — the second-largest custodian at $46.6 trillion in assets under custody — announced plans to launch digital asset custody in 2026, including transfer agency services for tokenized assets and the use of tokenized Treasurys as collateral. State Street partnered with Galaxy Digital to create a tokenized fund and is developing tokenized money-market funds, ETFs, deposits, and stablecoins.
Citigroup — with $2.57 trillion in assets under custody — has been developing an institutional-grade crypto custody platform for two to three years, according to its global head of partnerships and innovation, targeting asset managers, hedge funds, and institutional investors for a 2026 launch.
Morgan Stanley — filed for a dedicated "Morgan Stanley Digital Trust, National Association" with the OCC on February 18, 2026. The proposed entity will custody digital assets, execute purchases, sales, swaps, and transfers, and offer crypto staking services. The trust bank charter structure avoids the capital and liquidity requirements of deposit-taking institutions while establishing federally supervised fiduciary responsibility.
Combined, these four institutions alone hold over $100 trillion in traditional assets under custody and administration. Even a fractional allocation of their client base to digital assets would represent tens of billions in new custody flows.
Standard Chartered has moved faster than any other G-SIB in assembling a vertically integrated digital asset stack:
1. Custody (Zodia Acquisition — May 18, 2026): Standard Chartered accepted a non-binding offer to acquire the remaining shares of Zodia Custody, its crypto custodian subsidiary. The regulated custody operations will be absorbed into the bank's Financing and Securities Services division. Zodia's institutional infrastructure platform — its white-label digital asset technology tools — will be separated into an independent entity, Zodia Solutions, under the bank's SC Ventures arm, led by CEO Julian Sawyer.
2. Trading (GSR Stake — May 5, 2026): SC Ventures took a stake in GSR, a crypto trading and market-making firm founded by former Goldman Sachs traders, at a valuation exceeding $1 billion. GSR is seeking to raise up to $150 million from additional strategic investors. Standard Chartered introduced institutional spot Bitcoin and Ethereum trading in 2025, making it one of the first global banks to offer direct crypto execution.
3. Research and Advisory (Ongoing): Geoff Kendrick, Standard Chartered's global head of digital assets research, published a report on May 18 forecasting that tokenized assets on public blockchains will reach $4 trillion by the end of 2028, split evenly between stablecoins and tokenized real-world assets. The bank positions DeFi protocols as the core infrastructure layer for these on-chain assets, identifying deposits, lending, and capital efficiency as the primary adoption channels.
The combined effect: Standard Chartered can now custody client digital assets on bank-grade infrastructure, execute trades through a regulated market-maker relationship, offer tokenization advisory, and license its technology stack to other banks — all under a single umbrella. Julian Sawyer of Zodia observed that "digital asset custody is increasingly being delivered within banking environments" and that institutions are "seeking specialist infrastructure partners to support the launch and scale of digital asset services."
The custody market is bifurcating into two tiers. Crypto-native custodians — primarily Coinbase, BitGo, and Anchorage Digital — currently dominate.
Coinbase holds approximately $90 billion in assets under custody and safeguards more than 70% of U.S.-based crypto ETFs. Its conditional OCC trust bank charter, if finalized, would bring its custody operations under federal supervision for the first time.
BitGo priced its IPO at $18 per share in 2026, raising $212.8 million at an approximately $2.08 billion valuation — the first publicly traded company offering pure-play institutional crypto custody exposure. BitGo holds $64 billion in assets under custody.
Anchorage Digital holds a 7.7% custody market mindshare according to industry surveys, and was the first crypto company to receive a federal bank charter (OCC) in January 2021.
The entry of G-SIBs reshapes competitive dynamics. Banks bring existing client relationships across pension funds, sovereign wealth funds, and asset managers — clients that may prefer a single custodian for both traditional and digital assets over a crypto-native specialist. However, crypto-native firms have deeper technical infrastructure: multi-party computation (MPC) key management, cross-chain settlement, and staking operations that banks are still building or acquiring.
The custody provider services market itself — measured by fees and technology revenue — grew from $3.28 billion in 2025 to $3.69 billion in 2026, according to market research estimates, with projections reaching $7.40 billion by 2033 at a 29.5% CAGR. The underlying assets in custody represent a far larger number: the digital asset custody market surpassed $1 trillion in 2026 and is projected to reach $7 trillion by 2035.
Custody fees in traditional finance average 1-5 basis points on assets under custody. Crypto custody commands a premium — industry estimates range from 20-50 basis points — reflecting higher operational complexity, insurance costs, and cybersecurity requirements.
If the $1 trillion in digital assets under institutional custody generates an average of 25 basis points in annual custody fees, the total addressable fee pool is approximately $2.5 billion. At $7 trillion by 2035, even with fee compression to 15 basis points, annual custody revenue would reach $10.5 billion.
The economic question is whether bank entry compresses fees toward TradFi levels or whether the operational complexity of crypto custody sustains the premium. Banks entering with subsidized pricing to capture market share — a pattern visible in the brokerage fee war documented in prior webthreepedia coverage — could accelerate compression. Conversely, the ongoing prevalence of exploits and security incidents (over $99 million in cross-chain exploits in a five-day period in May 2026 alone) may justify persistent risk premiums.
From the economic-value perspective, custody represents one of the few segments in the blockchain economy generating genuine service revenue rather than relying on token inflation or subsidies. Unlike validator rewards or liquidity mining, custody fees are paid for a specific service — asset safekeeping — by clients willing to pay for it regardless of token price cycles. This positions custody as a structural revenue layer, albeit one that will face the same fee compression dynamics that have eroded margins across traditional financial services over the past three decades.
The digital asset custody market is undergoing a structural transformation from a crypto-native specialty into a bank-intermediated financial service. The regulatory gates opened by SAB 122 and the OCC's accelerated chartering process have compressed what might have been a decade-long migration into approximately 18 months.
The implications extend beyond custody itself. Banks that control the safekeeping layer position themselves to capture adjacent revenue streams: settlement, collateral management, securities lending, staking, and tokenized asset administration. Standard Chartered's three-pronged approach — custody, trading, and research advisory — illustrates the full-stack ambition.
For the broader blockchain economy, the institutionalization of custody is a net positive for revenue sustainability. Custody fees represent genuine economic value exchange rather than token redistribution. However, the concentration of custody among a small number of G-SIBs and OCC-chartered entities reintroduces the intermediary layer that blockchain architecture was originally designed to eliminate. Whether decentralized custody solutions — multi-signature wallets, MPC protocols, and smart-contract vaults — can compete with bank-grade custody on trust and regulatory compliance remains an open question.
The data is clear on the direction: institutional capital is entering digital assets, and it demands institutional custody. The race to build that infrastructure is no longer theoretical.
