"The OCC's decision to allow companies to obtain national trust bank charters to conduct substantial non-fiduciary activities exceeds authority Congress granted." — Rebeca Romero Rainey, President, Independent Community Bankers of America
Three distinct regulatory paths for institutional crypto custody are now open in the United States. Each carries different compliance costs, supervisory obligations, and legal risks. The Office of the Comptroller of the Currency has approved or conditionally approved 21 national trust bank charters since December 2025, at least 13 to crypto-native firms — a pace of 11 approvals in 83 days that triggered a federal lawsuit from the community banking lobby on October 2, 2026. The SEC proposed Rule 223-1 on October 1, creating a parallel custody framework that elevates state trust companies to qualified custodian status and permits adviser self-custody under narrow conditions. Meanwhile, traditional banks — Deutsche Bank, BNY Mellon, Morgan Stanley, Charles Schwab — are building crypto custody capacity through existing charters, bypassing both new frameworks entirely.
The custody provider market generates an estimated $3.5–3.7 billion in revenue in 2026, according to The Business Research Company. Total digital assets under institutional custody exceed $400 billion. The question now is which regulatory model captures the next increment of institutional flow — and whether the ICBA's lawsuit collapses the OCC path before most conditional approvals convert to operational charters.
The OCC approved or conditionally approved 21 national trust bank charters between December 2025 and October 2026, at least 13 involving crypto-native companies. The acceleration was unprecedented. On December 12, 2025, the OCC granted five conditional approvals simultaneously — Circle, Ripple, BitGo, Paxos, and Fidelity Digital Assets — the first time the agency had approved multiple crypto charters in a single day. By March 2026, Bridge/Stripe, Protego, and Crypto.com had received conditional approvals. Block filed its application for Builders Bank & Trust, N.A. on September 4, 2026. Coinbase and World Liberty Financial applications remain pending.
The OCC currently supervises approximately 60 national trust banks holding nearly $2 trillion in custody and safekeeping accounts. Adding 21 new charters in under a year represents a 35% increase in the supervised population.
The charter structure carries specific regulatory characteristics:
What it includes: Federal preemption of state money-transmitter licensing. A single national charter replacing the 50-state patchwork. Direct OCC supervision. Access to the Federal Reserve's payment systems.
What it excludes: No FDIC deposit insurance (these entities do not accept deposits). No Community Reinvestment Act obligations. No consolidated supervision by the Federal Reserve. No capital and liquidity requirements comparable to deposit-taking banks.
The asymmetry is the core of the ICBA's complaint. Community banks under $2.5 billion in assets report spending approximately $1.5 million annually on regulatory compliance that includes CRA reporting, FDIC assessments, and Fed supervisory requirements. National trust banks chartered for crypto custody face none of these costs.
Only one entity — Anchorage Digital Bank, chartered in January 2021 — has converted from conditional approval to fully operational status. Every other conditional approval remains in process, subject to the OCC's operational requirements and, now, the outcome of ICBA litigation.
Comptroller Jonathan Gould has publicly stated the OCC aims to process charter applications within 120 days. The agency's March 2026 final rule codified its interpretation that the National Bank Act authorizes trust banks performing custodial services that are not strictly fiduciary in nature.
On October 1, 2026, the SEC proposed replacing the existing custody framework (Rule 206(4)-2 under the Investment Advisers Act) with Rule 223-1 — a structural overhaul that addresses crypto for the first time. Comments are due December 7, 2026.
SEC Chairman Paul Atkins stated the proposal would "replace the grey of uncertainty created by custody rules crafted for a bygone era" with a clear framework.
The proposal creates two crypto custody pathways:
State trust companies as qualified custodians. State-chartered trust companies authorized by state banking regulators to custody crypto would qualify as permitted custodians under both the Advisers Act and the Investment Company Act. Requirements include written safeguarding policies, audited financial statements, internal control reports (SOC 2 or equivalent), and segregation of client assets. Advisers must conduct initial and annual due diligence before engaging any state trust company.
Conditional self-custody. An adviser may hold client crypto assets directly only when no qualified custodian will maintain the asset. Before taking self-custody, the adviser must: determine in writing that no qualified custodian is available; reaffirm that determination at least quarterly; demonstrate expertise in safeguarding the specific asset; implement joint authorization requiring at least two individuals for key management; maintain segregated client addresses; conduct annual cybersecurity risk assessments; obtain annual internal control reports from independent accountants; and deliver quarterly client statements showing wallet addresses, networks, balances, and transaction history.
The self-custody path is explicitly a fallback. It exists only for assets no qualified custodian will hold — not for assets the adviser prefers to custody itself.
Form ADV updates. Advisers engaging in crypto self-custody or tokenized private fund involvement must disclose these activities in Form ADV Item 9.
Legal basis shift. The current custody rule operates as an anti-fraud provision under Section 206(4). Proposed Rule 223-1 draws authority from Section 223 of the Advisers Act, added by the Dodd-Frank Act. This changes the legal foundation from fraud prevention to direct custody regulation — a distinction that affects enforcement posture and judicial review standards.
The proposal includes no transition period. If finalized as proposed, compliance would be required upon the effective date, though the SEC has requested comment on whether additional implementation time is needed.
The third path involves no new charter and no new rule. Existing bank holding companies and broker-dealers are adding crypto custody to their established operations:
Deutsche Bank activated crypto custody services in October 2026, offering institutional clients custody through its existing European banking license. Deutsche Bank holds approximately $1.7 trillion in assets on its balance sheet.
BNY Mellon holds $59.4 trillion in assets under custody as of March 2026. The bank added digital asset custody to its platform in 2022 and has expanded the service to include tokenized securities. BNY and Citadel Securities completed a tokenized Treasury triparty repo transaction in October 2026.
Morgan Stanley filed an OCC national trust charter application on February 18, 2026, while simultaneously building crypto capabilities through its E*TRADE platform for 8.6 million clients.
Charles Schwab opened crypto trading to 40.3 million brokerage accounts in October 2026.
Interactive Brokers launched Ethereum staking for eligible LLC clients on October 13, 2026.
These institutions operate under existing bank and broker-dealer regulatory frameworks — Federal Reserve supervision, FDIC insurance (where applicable), SEC registration, and decades of compliance infrastructure. They do not need OCC trust charters or SEC custody rule changes to offer crypto services. Their existing licenses are sufficient.
The competitive advantage is trust and distribution. BNY Mellon does not need to explain what a "qualified custodian" is to its clients — it has been one for 240 years. The disadvantage is speed. Traditional bank compliance processes, board approvals, and risk committee reviews typically extend product launch timelines by 12–18 months compared to crypto-native competitors.

The Independent Community Bankers of America filed suit on October 2, 2026, in the U.S. District Court for the District of Columbia against the OCC and Comptroller Jonathan Gould. The complaint challenges three distinct agency actions:
ICBA's central legal argument: the National Bank Act authorizes three categories of national banks — traditional depository banks, bankers' banks, and trust banks exercising fiduciary powers. The OCC, ICBA contends, has "effectively created a fourth category — a national bank that neither accepts deposits nor exercises fiduciary powers." ICBA relies on the Third Circuit's 1979 decision in National State Bank of Elizabeth v. Smith, arguing the 1978 statutory amendment merely confirmed the OCC's authority to limit bank activities to trust operations, not to expand trust bank authority to non-fiduciary services.
The relief sought is comprehensive: vacatur of the March 2026 rule, Interpretive Letter 1176, and Protego's conditional approval, plus an injunction preventing the OCC from using either policy to grant future charters.
The Bank Policy Institute, representing large banks, has expressed support for the principle that "entities should face the same rules and responsibilities as every other chartered institution," according to BPI executive Paige Pidano Paridon.
If the court grants ICBA's requested relief, the consequences propagate immediately. All 21 conditional approvals rest on the legal framework the lawsuit targets. Vacatur of the March 2026 rule and IL 1176 would remove the legal basis for every pending and conditionally approved crypto trust charter except Anchorage Digital Bank, which received its charter under different procedural circumstances in 2021.
Block's Builders Bank application, filed September 4, 2026, would be directly affected. Coinbase's pending application would face the same outcome. The OCC's 120-day processing target becomes irrelevant if the underlying authority is invalidated.
Each model creates different fee structures and captures different slices of the custody value chain.
OCC trust charter entities charge custody fees directly — typically 5–50 basis points annually on assets under custody, plus transaction fees for on-chain movements. Revenue accrues entirely to the charter holder. Without FDIC insurance or CRA costs, operating margins are structurally higher than traditional banks. The tradeoff: no deposit-funded balance sheet means no net interest income.
SEC Rule 223-1 participants operate in two tiers. State trust companies earn custody fees comparable to OCC trust banks. Advisers using self-custody capture the custody fee internally but bear full liability for key management, cybersecurity, and regulatory compliance — including annual accountant reports and quarterly client statements. The compliance cost of self-custody may exceed the fee savings for advisers with smaller crypto allocations.
Traditional banks layer crypto custody onto existing fee structures. BNY Mellon charges custody fees as part of its broader asset servicing relationships. Deutsche Bank integrates crypto into its prime brokerage and custody platform. The incremental cost of adding crypto to an existing $59.4 trillion custody operation is lower per unit than building standalone crypto custody from zero. The economic value flows through existing relationship pricing, where crypto is one product among many.
The market is segmented by client type. Crypto-native protocols and token issuers gravitate toward OCC trust charter holders that understand blockchain infrastructure. Registered investment advisers and regulated funds will likely follow the SEC Rule 223-1 path, using state trust companies or self-custody within the proposed framework. Pension funds, sovereign wealth funds, and large asset managers will default to traditional bank custody, where the operational and counterparty risk profiles match their existing compliance frameworks.
The United States now has three simultaneous pathways to institutional crypto custody, each governed by a different federal regulator with different requirements, different costs, and different legal risks. The OCC's trust charter path offers the fastest route for crypto-native firms but faces an existential legal challenge from an industry group representing 5,000 community banks. The SEC's Rule 223-1 offers the broadest potential reach — every registered investment adviser and regulated fund — but remains a proposal, not a rule. Traditional banks offer the deepest trust and the largest existing custody bases, but move at institutional speed.
The ICBA lawsuit introduces a binary variable into what was otherwise a gradual convergence. If the court upholds the OCC's chartering authority, the 21 conditional approvals proceed toward operational status, and the crypto-native custody sector gains permanent federal legitimacy. If the court vacates the underlying rule and guidance, the OCC path closes, and crypto-native firms must either obtain state trust charters (Model 2), partner with traditional banks (Model 3), or wait for Congress to act.
The economic stakes are measurable. Custody fees, transaction charges, and associated service revenue from institutional digital asset holdings represent a growing share of financial infrastructure revenue. Which model prevails determines not just who holds the keys, but who earns the fees.
