What Can U.S. Banks Do with Crypto Starting July 2026? FDIC Rule and GENIUS Act Explained

The final piece of the U.S. regulatory puzzle fell into place on April 7, 2026, when the FDIC Board of Directors approved the Notice of Proposed Rulemaking (NPRM) on payment stablecoins and bank crypto custody. Published in the Federal Register on April 10, the rule closes the legal triangle that began with the CLARITY Act (market structure) and continued with the GENIUS Act (federal stablecoin framework). Starting in July 2026, an FDIC-insured bank can issue a payment stablecoin and custody Bitcoin as a standard product line, subject to the same prudential standards that govern traditional fiduciary activities. The end of the "crypto vs. banks" era. The beginning of the "crypto within banks" era.

This article explains exactly what the new Subpart A / Subpart B to Part 350 requires, how it differs from the OCC framework from February, which banks are in line for July, and why this rule — combined with existing ETF products — marks a structural shift in how Americans will access digital assets. As we previously analyzed in the series on the CLARITY and GENIUS Acts, the complete puzzle can only be understood by seeing the three pieces fitted together.

What exactly did the FDIC approve on April 7, 2026?

The Board approved a Notice of Proposed Rulemaking (NPRM) that introduces Subpart A and Subpart B to Part 350 of the FDIC Rules and Regulations. Subpart A regulates Permitted Payment Stablecoin Issuers (PPSIs) under FDIC supervision; Subpart B regulates Insured Depository Institutions (IDIs) that provide digital asset custody or safeguarding services.

The timeline is aggressive, designed for the market to be fully operational before the statutory effective date of the GENIUS Act in January 2027:

July is the critical window. This is when banks can formally submit business plans and applications to operate stablecoin-issuing subsidiaries or digital asset custody services under the new federal framework. The process is not automatic: applications will be evaluated based on the applicant's financial capacity, the integrity of directors, and operational competence to manage stablecoin programs.

What does the FDIC require regarding stablecoin reserves?

The operational core of the rule lies in the reserve asset requirements. The FDIC requires every PPSI to maintain identifiable assets with a value not less than the total nominal amount of stablecoins in circulation. The composition is strictly limited to ensure immediate liquidity.

The 40% limit deserves specific attention. It seeks to avoid the systemic concentration that would occur if a stablecoin issuer kept all its cash in a single correspondent bank. If that bank entered stress, the redemption chain would be interrupted. By forcing diversification among at least three or four custodians, the FDIC protects global stability against individual insolvencies. The argument is analogous to the one justifying concentration limits in money market funds.

The monthly certification is another regime change. Stablecoin issuers like Circle (USDC) publish voluntary monthly attestations. Tether (USDT) publishes with less regularity and traceability. For a PPSI under FDIC supervision, attestation becomes a regulatory obligation, not a marketing practice. The shift in trust this introduces is considerable.

How does this affect a bank's regulatory capital?

The FDIC has proposed a specialized capital framework for PPSIs, recognizing that their risk profile differs from that of a traditional commercial bank that performs maturity transformation through lending. For IDIs operating a PPSI via a subsidiary, the proposal introduces a "deconsolidation and deduction" method.

Under this model, the parent bank must deconsolidate PPSI assets and liabilities for regulatory capital purposes and deduct any investment in the PPSI's retained earnings from its common equity tier 1 (CET1) capital. The practical effect: double counting of capital is avoided, and it ensures that PPSI risks do not reach the main bank's balance sheet. It is a banking version of the ring-fencing that applies to insurance subsidiaries or capital market units.

In addition, an "operational backstop" (operational backstop) is added: a liquid asset reserve equivalent to a specific period of operating expenses that ensures the issuer can continue redemption functions even in administrative stress scenarios. This is functionally equivalent to an operating liquidity cushion, not a capital reserve, and is explicitly distinguished from deposit insurance.

How does the FDIC framework differ from the OCC's of February 2026?

The Office of the Comptroller of the Currency (OCC) issued its own guidance under the GENIUS Act in February 2026, applicable to national banks. Although both agencies have coordinated the substance, there are operational differences that affect which type of banking license is preferable depending on the issuer's strategy.

The FDIC's flexibility on white labels is the most interesting strategic difference. It suggests that banks under FDIC supervision could issue different stablecoins for different business partners — a large retailer, a tech platform, an exchange — as long as they maintain clear protection mechanisms for each brand's holders. A bank like Citi or BNY Mellon could become an issuer of multiple B2B stablecoins simultaneously, each tailored to a use case.

Which banks are going to the July window first?

The industry response has been swift. Between late 2025 and the first quarter of 2026, eleven companies — from digital natives to Wall Street giants — have applied for or received conditional approvals for National Trust Bank charters from the OCC, positioning them for the July FDIC window. Four names stand out for their size and strategy.

JPMorgan Chase: "Smart Cash" Infrastructure

JPMorgan has moved from Dimon's public caution to active implementation of smart cash infrastructure. In his 2025 annual letter (published in April 2026), Jamie Dimon highlighted the importance of technology to move $10 trillion daily in seconds. The strategy focuses on allowing clients to automatically move funds from checking accounts to higher-yielding brokerage products, potentially including tokenized deposits or stablecoins. JPMorgan sees the FDIC framework as validation of its approach: tokenizing traditional bank deposits to improve 24/7 liquidity without creating a new type of instrument.

Citi: Making Bitcoin "Bankable"

Citi has announced plans to launch a full digital asset infrastructure in 2026. Under the leadership of Nisha Surendran, head of digital asset custody, it seeks to integrate Bitcoin into its $30 trillion traditional asset framework. Unlike previous models that offered limited access, Citi plans to hold native digital assets directly on its balance sheet, applying the same risk controls and reporting frameworks it uses for traditional securities. It is the most ambitious strategy among major U.S. banks.

BNY Mellon and State Street: The Institutional Trust Layer

BNY Mellon and State Street are positioning themselves as the custody and administration infrastructure for ETFs and institutional investors. BNY Mellon already serves as administrator and cash custodian for the Morgan Stanley Bitcoin Trust, a centerpiece of the banking ETF rollout we analyzed previously. State Street launched its Digital Asset Platform (DAP) in January 2026 and aims to enable pension funds and endowments to manage digital assets alongside stocks and bonds in a single reporting system.

How does the FDIC fit with the CLARITY Act and the GENIUS Act?

As we developed in the analysis of the CLARITY Act and GENIUS Act, the two laws define the federal architecture: CLARITY resolves SEC/CFTC jurisdiction by classifying digital assets as securities or commodities, and GENIUS establishes the framework for payment stablecoins with 1:1 reserves and a prohibition on yield to the holder. The FDIC rule is the missing piece: it brings the principles of those laws down to the concrete operational standards a bank must meet to issue or custody.

The combination allows a bank like Citi to offer Bitcoin custody — a digital commodity certified by CLARITY — settled with a stablecoin regulated by GENIUS and held in safeguard under FDIC standards. Three laws, three agencies, one coherent commercial product.

Why does the Fed insist that stablecoins do not pay interest?

The Federal Reserve does not issue the FDIC rule, but it plays a crucial coordination role through the Stablecoin Certification Review Committee (SCRC), chaired by the Secretary of the Treasury. The Fed's stance — articulated by Governor Michael Barr — focuses on financial stability and control of illicit financing.

Barr has drawn historical parallels with the "Free Banking Era" before 1860 and the Panic of 1907 to underscore the risks of allowing private payment instruments without solid liquidity backing. The Fed is particularly concerned about the potential inability to redeem stablecoins "at par" during market stress, which would trigger panic dynamics similar to those of money market funds in 2008.

Hence the prohibition on yields. If a stablecoin paid interest to the holder, it would functionally transform from a payment instrument to an investment vehicle, competing directly with bank deposits and increasing the volatility of the financial system's deposit base. The Treasury and the Fed prefer to maintain that sharp line: stablecoins serve for payment, deposits serve for saving, tokenized funds (like BUIDL) serve for yield — three categories, three regimes.

How does this connect with Bitcoin ETFs and yield funds?

The FDIC rule does not operate in isolation. It connects with the explosion of exchange-traded products and institutional yield funds that BlackRock and Morgan Stanley have deployed in 2026. The Morgan Stanley Bitcoin Trust (MSBT) launched on April 8, 2026, on NYSE Arca with a 0.14% fee, using Coinbase as the digital asset custodian and BNY Mellon as the administrator. It is the first time a major U.S. commercial bank has issued its own spot Bitcoin ETF.

In parallel, BlackRock has consolidated its institutional yield offering. ETHB (iShares Staked Ethereum Trust) was the first crypto ETF with built-in staking, launched in March 2026 with a net yield between 1.9% and 2.4% annually. BUIDL (USD Institutional Digital Liquidity Fund) integrated with UniswapX technology in February 2026 so institutional investors can trade fund shares using DeFi infrastructure while maintaining regulatory protection. As we documented when analyzing these products, BUIDL and ETHB redefine what "institutional yield" means on a fiduciary balance sheet.

The FDIC rule directly reinforces this structure: banks acting as custodians for the underlying assets of these funds must now meet the 2026 framework's segregation and security standards. Without this rule, ETFs and tokenized funds would operate with ambiguous operational risk. With it, the issuer-custodian-investor triangle is resolved.

Does a bank-issued stablecoin have FDIC insurance?

The most frequent question from retail users is also one of the rule's subtlest answers. The GENIUS Act and the FDIC proposal are explicit: payment stablecoins are not covered by deposit insurance. A stablecoin holder is not a bank depositor in the traditional sense. What they have is legal priority over the basket of reserve assets in case of issuer insolvency, with the right to redeem at par within two business days.

The difference is subtle but important. A bank deposit of up to $250,000 is insured by the FDIC: if the bank fails, the depositor is paid quickly from a public insurance fund. A payment stablecoin issued by a PPSI is a payment instrument with audited 1:1 backing: if the issuer fails, the holder has the right to be paid from the reserve basket, with priority over other creditors, but the process may be slower and the final value depends on the state of the basket.

In practice, if reserves are diversified (40% rule), liquid (10% in cash or Fed), and certified monthly, the functional difference for the average user is small. But it is worth knowing it is not the same.

View Bank Stablecoins and DeFi Self-Custody in a Single Dashboard with CleanSky

With the FDIC rule in place, users in the U.S. (and any other jurisdiction adopting comparable frameworks) will end up holding bank stablecoins issued by Citi or JPMorgan alongside existing private stablecoins (USDC, USDT) and DeFi positions in decentralized protocols. CleanSky consolidates all that visibility: you paste your wallet address, the tool is read-only — no account, no permissions, no access to your money — and it scans more than 50 networks and 484 protocols, showing every asset, every yield, and every risk exposure.

It works like a banking app for DeFi: just as your bank shows you accounts, cards, and investment products at a glance, CleanSky shows you your stablecoins (bank or private), your Bitcoin (in self-custody, tokenized ETFs, or yield products), your DeFi positions, and your associated risks in a single updated dashboard.

Conclusion: The End of "Crypto vs. Banks"

The implementation of the FDIC rule in July 2026 marks the end of the "shadow banking" era for digital assets. By making Bitcoin custody and stablecoin issuance a standard product line, regulators have achieved three simultaneous goals: reserve transparency (monthly certifications eliminate doubts about backing), consumer protection (legal priority over the reserve basket even without pass-through insurance), and operational efficiency (stablecoins and tokenized deposits enable 24/7 settlements that reduce correspondent costs).

Starting in July, the question for a U.S. bank will no longer be whether it can interact with crypto. It will be how quickly it can integrate these tools into its commercial offering without losing share to early adopters — JPMorgan, Citi, BNY Mellon, State Street. The final piece of the puzzle is in place, and the result is a financial system where the digital asset is simply another form of bank money operating under federal surveillance. As we argued in the analysis of Bitcoin as a sovereign reserve asset, institutional integration is not a passing fad: it is the way the dominant financial system is absorbing the infrastructure that operated on its periphery for 15 years.
