Banks Crash the Stablecoin Party as GENIUS Act Reshapes a $323B Market

The total stablecoin market cap crossed $323 billion under the GENIUS Act, and the same dollar-rail is now being chased by Tether, Circle, JPMorgan, Bank of America, Stripe, Klarna, and PayPal at the same time. What used to be a crypto-native corner of finance is becoming a payment rail that every major U.S. bank and fintech is trying to own. The crowded bandwagon rewards distribution, and the losers in a zero-sum reshuffle will not be named in any launch announcement.

The 2026 stablecoin market is the first dollar-denominated financial rail where the issuer, the custodian, the bank, and the checkout button can all sit on the same balance sheet. The question is who collects the float, who keeps the customer, and whose deposits stop growing because the corporate treasury moved.

The GENIUS Act Built the Track

President Donald Trump signed the Guiding and Establishing National Innovation for U.S. Stablecoins Act on July 18, 2025, creating the first federal framework for payment stablecoins. The law splits oversight by size: issuers with less than $10 billion in circulation answer to state regulators, and issuers above $10 billion fall under the Office of the Comptroller of the Currency. Banks, credit unions, and licensed non-bank firms can all apply.

Every issuer must hold 1:1 reserves in cash or short-term Treasuries, submit to monthly audits, and obtain a license. The act carves payment stablecoins out of SEC and CFTC jurisdiction entirely, a legal clarity that is what attracted the banks in the first place.

On April 7, 2026, the FDIC Board of Directors approved a notice of proposed rulemaking implementing those requirements, a prudential framework covering reserve assets, redemption, capital, and risk management for FDIC-supervised permitted payment stablecoin issuers. The FDIC’s April 7 GENIUS Act implementing proposal was the agency’s second rulemaking under the act, following a December 19, 2025 proposed rule on application procedures for insured depository institutions that want to issue through a subsidiary. Comments on the latest proposal run for 60 days after Federal Register publication.

Tether’s USDT and Circle’s USDC each clear the $10 billion threshold, according to Forbes’ April 2026 reporting, and now sit under the same OCC regime as any bank-issued competitor. The race is no longer a regulatory gray area. It is a federal permission slip to compete for the same customers.

Wall Street Pulls Up a Chair

JPMorgan put JPMD, its USD deposit token, on Coinbase’s Base public blockchain on November 12, 2025, making it the first major U.S. bank to operate on a public chain. The token is technically a deposit token rather than a GENIUS-Act payment stablecoin, but the institutional on-chain rails are already live, and JPMorgan had been running deposit tokens through its Kinexys platform since June 2025.

Bank of America, Citigroup, and Wells Fargo explored a joint stablecoin project as early as May 2025, according to The Wall Street Journal. Wells Fargo has separately piloted its own digital cash token for internal settlement. Bank of America’s Brian Moynihan was blunt about the bank-issued case. After the law passed, Moynihan said, “If they make that legal, we will go into that business.” By January 2026 he was warning that up to $6 trillion in deposits, roughly a third of all U.S. commercial bank deposits, could eventually shift to stablecoins if regulators permitted yield.

The block on bank-issued stablecoins is the GENIUS Act’s strict yield ban. The OCC and FDIC have interpreted the prohibition strictly, barring even third-party yield arrangements. Bank savings accounts pay interest; bank-issued stablecoins cannot, under the current rules. A Forbes account of Wall Street’s stablecoin entry frames Moynihan’s $6 trillion warning as conditional on that yield rule loosening.

Tether Storms Back with USAT

Tether launched USA₮ on January 27, 2026, the first stablecoin purpose-built for the GENIUS Act’s federal regime. The issuer is Anchorage Digital Bank, N.A., America’s first federally chartered digital asset bank. Tether framed the launch as a direct answer to the U.S. market’s compliance demand, and the token is now available to U.S. users seeking a dollar-backed product built to operate inside the federal framework.

Cantor Fitzgerald serves as designated reserve custodian and preferred primary dealer for USA₮, with monthly audits designed to address the transparency criticisms that have hung over USDT for a decade. During the first phase, USA₮ is listed on Bybit, Crypto.com, Kraken, OKX, and Moonpay. CEO Paolo Ardoino positioned the new token as additive, not a replacement for USDT. “USA₮ offers institutions an additional option: a dollar-backed token made in America,” Ardoino said in the company’s January 27 USA₮ launch announcement. Bo Hines, former White House Crypto Council executive director and now CEO of Tether USA₮, called the token “a digital dollar that is designed to meet federal regulatory expectations.”

The launch reorders the competitive map. Tether Group ranks as the 17th-largest holder of U.S. Treasuries globally, ahead of sovereign holders including Germany, South Korea, and Australia, per the same announcement. USA₮ is aimed at the U.S. institutional market for settlement and treasury operations. USDT continues to anchor offshore liquidity and trading depth. Tether is now meeting the U.S. market on U.S. terms.

Stripe, Klarna, and the Fintech Stack

Stripe closed its $1.1 billion acquisition of stablecoin-orchestration platform Bridge in February 2025, the largest acquisition in the company’s history. With crypto investor Paradigm, Stripe incubated Tempo, a Layer-1 blockchain purpose-built for stablecoin payments, announced September 4, 2025, and live since March 2026 with a machine-payments protocol designed for AI agents to settle in stablecoins.

KlarnaUSD, the buy-now-pay-later giant’s dollar-pegged stablecoin, debuts on Tempo, issued by Bridge, with mainnet launch set for 2026. PayPal, the established incumbent on the consumer side, scaled PYUSD to 70 markets in March 2026. The fintech stack’s combined moves on the rail since early 2025:

• Stripe closed its $1.1 billion acquisition of Bridge in February 2025.
• Stripe and Paradigm incubated the Tempo Layer-1 blockchain, announced September 4, 2025, and live since March 2026.
• KlarnaUSD launches on Tempo, issued by Bridge, first bank-issued stablecoin on the network, set for mainnet in 2026.
• Stripe’s Link now accepts stablecoins, and PayPal’s PYUSD scaled to 70 markets in March 2026.

Tempo’s design and Stripe’s checkout layer, including the agent wallet inside Link, point to where the next volume is expected to come from. Solana and Google Cloud already shipped Pay.sh letting AI agents settle in USDC, and Animoca’s investment in AllScale extends stablecoin rails to more than 600 portfolio firms. Stripe’s announcement at Sessions 2026 included 288 product launches in one morning. The detail of everything Stripe unveiled at Sessions 2026 runs from a Stripe Reader T600 countertop device to the Machine Payments Protocol co-authored with Tempo, with stablecoin acceptance threaded through both consumer checkout and agentic flows.

Forecasters Disagree by Trillions

Standard Chartered’s April 2025 forecast, written before GENIUS passed, called for stablecoin supply to rise from roughly $230 billion at the time to $2 trillion by the end of 2028. The drivers were U.S. legislation and the implied $1.6 trillion in T-bill buying from reserves, enough, in Standard Chartered’s view, to absorb all new issuance during Trump’s second term.

JPMorgan’s research team cut its own stablecoin market forecast by half in mid-2025, calling predictions of $1 to $2 trillion by 2028 highly unlikely. The disagreement is attributed. Standard Chartered holds to its $2 trillion by 2028 call in subsequent commentary. Two of the largest research desks in U.S. bank finance sit on opposite sides of a trillion-dollar question. The detail of Standard Chartered’s $2 trillion by 2028 forecast runs through reserve composition, T-bill duration, and dollar hegemony. The market cap itself, as of April 2026 per DefiLlama data cited in Forbes’ reporting, sits at $323 billion.

• $323 billion – total stablecoin market cap (DefiLlama, April 2026).
• $184 billion – Tether’s USDT in circulation (Forbes, April 2026).
• $77 billion – Circle’s USDC in circulation (Forbes, April 2026).
• $2 trillion – Standard Chartered’s forecast for end-2028.
• $6 trillion – BofA’s deposit-shift scenario if yield payments are permitted.

21Shares forecasts the stablecoin market will exceed $1 trillion by the end of 2026, more than tripling its current size, driven partly by bank entry. Galaxy Digital predicts stablecoins will overtake ACH transaction volume this year. The bull case and the bear case both fit inside the GENIUS Act’s text.

Who Pays When the Banks Win

The crowded bandwagon rewards distribution. Banks bring corporate-treasury accounts and custody relationships; Stripe brings the checkout layer; Klarna brings buy-now-pay-later merchants; PayPal brings Venmo and hundreds of millions of consumer accounts. Tether and Circle bring offshore liquidity, trading depth, and the issuer-of-record status that pre-dates the GENIUS Act by a decade. The platform-native and crypto-native issuers are now competing on the same distribution map.

The counter-party is the deposit base, and the stakes for the losers are concrete:

1. Commercial bank deposits, if bank-issued tokens win the corporate-treasury use case and GENIUS Act rules later loosen on yield.
2. Crypto-native issuer margins, as the GENIUS Act’s reserve rules compress yield on float and force shorter-duration holdings.
3. Smaller fintech stablecoins, if a handful of bank- and platform-native issuers consolidate distribution.

On the issuer-margin question, the multi-issuer Stablecoin FX Layer on Uniswap v4 is one of the first concrete attempts to share liquidity across competing issuers. The bigger gatekeeper is the yield ban. If it loosens, Moynihan’s $6 trillion scenario comes closer. If it doesn’t, the bank-issued stablecoin ends up looking like a wholesale payment rail rather than a deposit substitute, and the crowded bandwagon turns into a payment-rail merger wave.

Frequently Asked Questions

What is the GENIUS Act?

The Guiding and Establishing National Innovation for U.S. Stablecoins Act is the first federal law covering payment stablecoins. It was signed on July 18, 2025. It requires 1:1 reserves in cash or short-term Treasuries, monthly audits, and OCC oversight for issuers above $10 billion in circulation. The law carves payment stablecoins out of SEC and CFTC jurisdiction.

Who can issue a stablecoin in the U.S. now?

Permitted payment stablecoin issuers under state or federal oversight, plus insured depository institutions operating under FDIC rules. The FDIC issued an application-procedures proposed rule on December 19, 2025, and a prudential-standards proposed rule on April 7, 2026.

Is USDT still the biggest stablecoin?

USDT was reported at roughly $184 billion in circulation in Forbes’ April 2026 coverage, ahead of USDC at roughly $77 billion. Both clear the $10 billion OCC threshold and face federal oversight.

What is USA₮ / USAT?

USA₮ is Tether’s GENIUS-Act-compliant U.S. stablecoin, launched January 27, 2026. It is issued by Anchorage Digital Bank, with Cantor Fitzgerald as reserve custodian.

How big will the stablecoin market get?

Forecasts diverge. Standard Chartered’s April 2025 call is $2 trillion by end-2028. JPMorgan’s research team cut its prior view by half. 21Shares projects the market will exceed $1 trillion by the end of 2026.
