Why Banks Are Building a Digital Dollar Network

John.H·Aug 19, 2026·10 min read

Twenty-five of the largest banks in the United States are building a shared tokenized deposit network through The Clearing House, targeting the first half of 2027.

In January 2026, Bank of America CEO Brian Moynihan issued a warning that rattled the banking industry. If regulators allow stablecoins to pay interest, he said, up to $6 trillion in bank deposits, roughly a third of all U.S. commercial bank deposits, could migrate on-chain. Six months later, 25 of the largest banks in the country announced they were building a shared blockchain network to make sure that does not happen.

The initiative, coordinated through The Clearing House with a target launch in the first half of 2027, is the banking industry's most significant collective response to the stablecoin threat. JPMorgan, Bank of America, Citigroup, Wells Fargo, HSBC, BNY, BMO, Citizens Financial, Fifth Third, Huntington, KeyBank, PNC, Regions, Santander, TD Bank, Truist, and U.S. Bank are all participating. The network would allow member banks to move tokenized versions of customer deposits between institutions around the clock, with instant settlement connected to the existing CHIPS and RTP payment rails.

This is not a pilot or a proof of concept. It is a coordinated industry response to a competitive threat that has grown too large to ignore.

What Tokenized Deposits Actually Are

A tokenized deposit is a blockchain-based representation of money that a customer already holds at a bank. Unlike a stablecoin, which is issued by a non-bank entity and backed by reserves held in a separate account, a tokenized deposit remains on the bank's balance sheet. It carries FDIC insurance up to the statutory $250,000 limit, just like any other bank deposit. The bank can pay interest on it, lend against it, and manage it within the same regulatory framework that governs all commercial bank operations.

The distinction matters because it determines who bears the risk and who benefits from the float. When a customer holds USDT or USDC, that money leaves the banking system. The stablecoin issuer parks the reserves in Treasury bills and earns the yield. The customer gets a digital dollar that moves quickly and works around the clock, but they give up deposit insurance, and under the GENIUS Act, they cannot receive interest from the issuer.

When a customer holds a tokenized deposit, the money stays in the bank. The bank retains access to its cheapest funding source, the customer retains FDIC protection, and both parties operate within a regulatory framework that has existed for nearly a century. The difference is that the deposit now moves on blockchain infrastructure, enabling 24/7 settlement, programmable payments, and cross-border transfers without correspondent banking delays.

Why Now

Three forces converged in 2026 to accelerate the banking industry's response.

The first is the sheer scale of the stablecoin market. Total stablecoin supply reached approximately $313 billion by mid-2026, up about 23% year over year and 99% denominated in U.S. dollars. Tether holds roughly $183 billion in market capitalization, representing 59% of the market, while Circle's USDC accounts for approximately $75 billion at 24%. Stablecoin transaction volume hit a record $4.5 trillion in the first quarter of 2026 alone, approaching the scale of Visa's annual throughput.

These are not speculative assets circulating within crypto exchanges. Stablecoins are increasingly used for B2B payments, cross-border transfers, and corporate treasury management, precisely the services that generate fee income for banks.

The second force is the GENIUS Act. Signed into law on July 18, 2025, the GENIUS Act created the first federal regulatory framework for payment stablecoins. It established three classes of permitted issuers: subsidiaries of insured depository institutions, federally qualified nonbank issuers supervised by the OCC, and state-qualified issuers. The law explicitly prohibits stablecoin issuers from paying interest on their tokens, a provision that banks lobbied for aggressively.

But the interest ban has proven porous. Coinbase pays USDC holders 3.5% APY on balances inside its app, structured as a "loyalty reward" funded through a 50/50 revenue share of Circle's reserve income. The arrangement does not technically violate the GENIUS Act because Coinbase, not Circle, makes the payment, and it is classified as a reward rather than interest. Whether this distinction survives regulatory scrutiny remains an open question, but the practical effect is that retail customers can already earn yield on stablecoins in a way that competes directly with savings accounts.

The third force is JPMorgan. The bank's Kinexys platform has processed more than $4 trillion in cumulative transaction volume and now averages roughly $7 billion per day. In early 2026, JPMorgan deployed its deposit token, JPM Coin (ticker: JPMD), on Coinbase's Base network, making it the first major bank to operate a native payment product on a public blockchain. B2C2, Coinbase, and Mastercard have all completed live transactions using the token. The euro-denominated version, JPME, is in development.

JPMorgan's move onto a public blockchain was a signal to the rest of the industry. If the largest bank in the United States is willing to put deposit tokens on the same infrastructure that stablecoins use, the interoperability barrier between bank money and crypto money is collapsing.

What the Banks Are Building

The shared network through The Clearing House is designed to solve a problem that individual bank efforts cannot address on their own: interbank settlement.

As Brookings fellow Nellie Liang observed in April 2026, interbank settlement of tokenized deposits on private blockchains currently does not exist. JPMorgan's Kinexys processes $7 billion a day, but that volume is confined to intra-bank transactions. A JPMorgan corporate client can move tokenized dollars to another JPMorgan client instantly, but transferring those same dollars to a Citigroup client requires falling back to traditional payment rails with their associated delays and costs.

The Clearing House network would eliminate that limitation. Member banks would issue tokenized deposits on shared infrastructure, enabling 24/7 interbank transfers with instant finality. The network connects to CHIPS, which settles approximately $1.8 trillion in interbank payments daily, and RTP, the real-time payment system that The Clearing House already operates. The result would be a programmable settlement layer that keeps deposits within the regulated banking system while matching the speed and availability that stablecoins offer.

For corporate treasurers, the appeal is programmability. Wells Fargo, which announced its own tokenized deposit platform on August 4, 2026, with a Fall 2026 launch for corporate and commercial clients, has built its system around smart contract-based conditional logic. Corporate users can set delivery-versus-payment triggers, time-based fund releases, and counterparty-specific routing rules. The system executes these conditions automatically, removing manual processes from treasury operations. The initial capability is USD-GBP cross-border payments that settle around the clock, with expansion to additional currencies planned through 2027.

What the Banks Have That Stablecoins Do Not

The banking industry's pitch rests on three structural advantages that stablecoins cannot replicate under current law.

The first is FDIC insurance. A tokenized deposit carries the same $250,000 coverage as a deposit recorded in a traditional core banking system. The FDIC has confirmed that its statutory definition of a deposit is technology-neutral, meaning that the blockchain representation does not alter the insurance treatment. Stablecoins have no equivalent protection. If a stablecoin issuer fails, holders are general creditors with no guaranteed recovery.

The second is interest payments. Banks can pay interest on tokenized deposits just as they pay interest on any other deposit. The GENIUS Act bars stablecoin issuers from paying interest directly. While platforms like Coinbase have found workarounds through loyalty programs, the regulatory distinction gives banks a potential pricing advantage if they choose to compete for deposits on yield.

The third is the Federal Reserve's discount window. Banks with deposits on their balance sheets can access emergency liquidity from the Fed. Stablecoin issuers cannot. This matters during periods of market stress, when the ability to borrow against deposit liabilities provides a stability buffer that non-bank issuers lack.

What Stablecoins Have That Banks Do Not

The advantages do not all flow in one direction. Stablecoins have built a global payment network that banks are still trying to replicate.

Stablecoins work across borders without correspondent banking relationships. A USDC transfer from New York to Lagos settles in minutes at near-zero cost. The equivalent bank wire requires multiple intermediaries, compliance checks at each step, and settlement times measured in days. For remittances, trade finance, and emerging market payments, stablecoins have a structural advantage that tokenized deposits will not match until the shared banking network expands beyond domestic settlement.

Stablecoins are also composable with decentralized finance. A tokenized deposit on a private bank network cannot be used as collateral in a DeFi lending protocol or deposited into an automated market maker. The deposit remains within the bank's controlled environment, which limits its utility for users who want to interact with the broader on-chain economy.

The open question is whether composability matters for the customers that banks care about most. Multinational corporations managing treasury operations are not looking to provide liquidity on decentralized exchanges. They want programmable payments, real-time settlement, and regulatory clarity, all of which the tokenized deposit network is designed to provide. The battle for retail deposits and cross-border payments is more contested.

The Yield Loophole

The most contentious issue in the banks-versus-stablecoins competition is yield.

The GENIUS Act banned interest payments by stablecoin issuers to protect bank deposits. But the ban created an arbitrage opportunity. Coinbase's 3.5% APY on USDC balances is funded by Circle's reserve income, which is generated by investing stablecoin reserves in Treasury bills yielding approximately 4.5% to 5%. The payment is structured as a loyalty reward from the exchange, not interest from the issuer, placing it in a legal gray zone that regulators have not yet resolved.

The debate has become a central feature of the comment period for Treasury's GENIUS Act implementation rules. Banks argue that any mechanism that routes reserve income to stablecoin holders, regardless of the legal label, constitutes a de facto interest payment and violates the statute's intent. Exchanges counter that the GENIUS Act regulates issuers, not platforms, and that exchange-based rewards are no different from credit card cashback programs.

The outcome of this debate will shape the competitive landscape. If regulators close the loophole, stablecoins lose their most powerful tool for attracting and retaining retail capital. If the loophole survives, banks will need to compete on yield, which means paying more for deposits and accepting lower margins on their lending books.

What This Means for the Market

The tokenized deposit network is not a replacement for stablecoins. It is a parallel system built to serve a different set of customers with a different set of guarantees. Stablecoins will continue to dominate cross-border payments, DeFi, and markets where banking infrastructure is limited or unreliable. Tokenized deposits will serve institutional and corporate users who need the regulatory protections, insurance coverage, and interest-bearing capabilities that only bank money can provide.

The competitive dynamic is less about which system wins and more about where the boundary settles. Every dollar that moves through a tokenized deposit network is a dollar that stays on a bank's balance sheet, available to fund lending and generate interest income. Every dollar that moves into a stablecoin is a dollar that leaves the banking system, with its yield captured by the issuer rather than the bank.

With 24 of the 50 largest U.S. banks now actively tracking tokenized deposit technology and four already operating live products, the infrastructure race is well under way. The shared network through The Clearing House, if it launches on schedule in the first half of 2027, will represent the first time that the banking industry has collectively deployed blockchain infrastructure at scale. Whether it arrives quickly enough to blunt the stablecoin market's momentum is the question that the next 12 months will answer.
