The dollar-pegged token market has entered its most contested phase since the sector’s inception, and the first week of July 2026 has crystallized the battle lines. A consortium of more than 140 companies — including BlackRock, Ripple, Visa, Mastercard, Stripe, and Coinbase — has unveiled Open USD (OUSD), a token aimed squarely at the revenue model that made Circle a public-market darling, and Circle’s stock fell sharply on the news. At the same time, Ripple’s RLUSD has pushed XRP Ledger settlement activity past $2.5 billion, and a coalition of banks is lobbying Washington to close what it calls the interest “loophole” in the GENIUS Act. Together, these threads describe a stablecoin market being reshaped simultaneously by new entrants, new rails, and a regulatory framework whose final contours are still being fought over.

A 140-Company Consortium Fires the Opening Shot

On June 30, 2026, a group calling itself Open Standard announced Open USD, pitched as the first major dollar token governed by the businesses that use it rather than owned by a single issuer. According to Yahoo Finance, the consortium spans payments giants Visa and Mastercard, asset manager BlackRock, banks including BNY Mellon and Standard Chartered, technology firms such as Google, IBM, and Samsung, and crypto-native platforms including Coinbase and Ripple. The Next Web reported that more than 140 firms have lined up behind the project, which remains pre-launch with an expected go-live later in 2026.

The structural innovation is economic rather than technical. A traditional issuer keeps the interest earned on the Treasury bills and cash backing its coin — the model that generates the bulk of Circle’s and Tether’s revenue. Open USD is instead designed to hand nearly all of that reserve yield back to the businesses that adopt it, according to Bitrue’s breakdown of the launch. For a merchant, exchange, or fintech deciding which token to hold on its balance sheet, the difference between earning a share of roughly 4-5% on reserves and earning nothing is not a rounding error; at scale it is a treasury-management decision.

That is why the announcement landed as a direct attack on incumbents. The Coin Republic framed OUSD as an emerging rival to USDC specifically, and the market agreed: Circle shares dropped between 15% and 17% on the day of the announcement, per Cryptonews. The awkward twist is that several OUSD backers — BlackRock, which manages the Circle Reserve Fund, and BNY, Circle’s primary custodian — are also core partners in Circle’s own ecosystem, meaning the consortium effectively pulls familiar institutional names onto a rival platform.

Circle’s Position: Strong Fundamentals, Shaken Stock

None of this means Circle is losing on current numbers. According to Circle’s Q1 2026 filing cited by CoinLaw, USDC in circulation grew 28% year-over-year to $77.0 billion as of March 31, 2026, while on-chain transaction volume grew 263% to $21.5 trillion. DefiLlama data from late June 2026 puts USDC’s on-chain supply at roughly $74.9 billion, good for about 23.8% of a total market that has swelled to approximately $315 billion. Tether’s USDT remains the leader at around $186 billion and 59% dominance, and the two coins together control roughly 83% of the market.

The broader market backdrop is one of rapid expansion: total supply has nearly doubled from $161.5 billion in mid-2024 to about $315 billion in mid-2026, per CoinLaw, with Ethereum and Tron together hosting roughly 80% of all value. Growth, in other words, is not the problem. The problem OUSD poses is margin. Circle’s business is built on keeping reserve interest; a consortium stablecoin that redistributes that interest to adopters attacks the exact mechanism that converts circulating scale into Circle’s earnings. Whether Open Standard can execute — coordinating 140-plus companies is famously harder than announcing them, and prior consortium efforts such as Facebook’s Diem collapsed before launch — remains an open question. But the market’s immediate repricing of Circle suggests investors view the threat as credible enough to discount now, per The Crypto Times.

Circle is not without responses. The company could deepen its own revenue-sharing arrangements with distribution partners, lean on its first-mover regulatory position, or compete on the infrastructure layer — cross-chain transfer protocols, developer tooling, and banking integrations built over nearly a decade — where a not-yet-launched consortium has nothing to show. Incumbency in the stablecoin business has historically proven sticky: liquidity attracts liquidity, and the coin with the deepest order books and the most exchange listings tends to keep them. What has changed is that, for the first time, the challenger is not a scrappy startup but a coalition that includes Circle’s own custodian and reserve manager, several of the largest payment networks on earth, and the world’s largest asset manager. Stickiness has never been tested against that.

Ripple’s RLUSD Quietly Builds Settlement Muscle

While the OUSD announcement grabbed headlines, Ripple’s own dollar token has been compounding more quietly. Research published June 30 by Evernorth, a Ripple-backed XRP treasury firm, found that RLUSD activity has driven XRP Ledger settlement volume above $2.5 billion, as reported by Bitcoinist and crypto.news. The growth curve behind that headline number is steep:

• RLUSD in circulation on the XRP Ledger grew from about $20 million at the end of 2024 to roughly $800 million by late June 2026, per CoinGape’s coverage of the Evernorth report.
• Monthly RLUSD-related transactions rose from about 54,000 in December 2024 to between 600,000 and 1.1 million per month in 2026.
• RLUSD’s share of all on-chain XRPL trading climbed from under 1% to about 12%, with the RLUSD/XRP pair alone approaching $900 million in volume, according to Bitcoin.com News.

Evernorth’s research argues that rather than cannibalizing XRP, RLUSD has deepened liquidity across the ledger and pulled regulated payment flows — including U.S.-Mexico settlement corridors paired with the peso-pegged MXNB — onto XRPL rails. Yahoo Finance separately reported that XRPL-based supply of Ripple’s token surged 22% in a recent stretch to $762 million. It is worth flagging the obvious caveat: Evernorth is Ripple-backed, so its framing serves Ripple’s interests, even if the underlying on-chain figures are independently observable. Ripple’s simultaneous participation in the OUSD consortium also suggests the company is hedging — building its own branded stablecoin while buying a seat at the table of the industry-wide alternative. If the settlement-volume trend holds, RLUSD’s significance may lie less in its absolute size than in demonstrating that a compliance-first token can win institutional payment flows that neither USDT’s offshore model nor a retail-facing coin was built to serve.

The GENIUS Act: The Rulebook Behind the War

All of this competition is unfolding inside a legal framework that did not exist two years ago. The GENIUS Act, signed into law in July 2025, created the first comprehensive U.S. federal regime for payment stablecoins. Its core requirements are straightforward: issuers must back tokens 1:1 with high-quality liquid reserves such as cash, insured deposits, and short-term Treasuries; they must publish regular reserve disclosures; only “permitted payment stablecoin issuers” — federally or state-qualified entities under bank-style supervision — may issue in the U.S. market; and, critically, issuers are prohibited from paying interest or yield to holders.

Implementation is now in full swing. The Office of the Comptroller of the Currency issued a notice of proposed rulemaking on February 25, 2026 to operationalize the statute, covering applications for federal issuer charters and the supervisory regime that comes with them, as analyzed by Latham & Watkins. The law’s architecture has had a clarifying effect on the market: it legitimized the asset class for institutions that previously could not touch it — arguably a precondition for a consortium like Open Standard attracting Visa, Mastercard, and BlackRock — while simultaneously hard-coding the question that now dominates the policy fight: if issuers cannot pay yield, who gets to capture the interest on more than $300 billion of reserves?

The “permitted issuer” gate is arguably the framework’s most consequential feature for the competitive landscape. Under the statute’s structure, a would-be stablecoin issuer must either obtain federal approval through the OCC or qualify under a state regime certified as substantially similar, and the law contemplates restrictions on foreign-issued tokens accessing the U.S. market absent comparable home-country regulation. For the OUSD consortium, that means the project cannot simply launch; it must route issuance through an entity that clears the same regulatory bar Circle already clears. For Ripple, which has publicly pursued banking-adjacent licensure, RLUSD’s positioning as a regulated, enterprise-grade stablecoin is itself a bet that the GENIUS Act framework rewards compliance-first design. The rulebook, in short, does not just constrain the players — it defines who is allowed on the field.

Banks vs. Exchanges: The Fight Over the Yield Loophole

The GENIUS Act’s interest ban applies to issuers — but not, on its face, to the exchanges and platforms that distribute the tokens. That gap is what the banking industry calls the loophole. Coinbase, for example, pays rewards to customers holding USDC on its platform, funded through its revenue-sharing arrangement with Circle rather than by Circle directly — an arrangement Forbes described as a “Coinbase-shaped hole” in the yield ban. A Congressional Research Service brief on the stablecoin yield debate notes that such issuer-platform arrangements have effectively circumvented the legislative prohibition in practice.

The banking lobby’s response has been forceful. The Bank Policy Institute has argued that Congress and regulators must close the payment-of-interest gap, and the American Bankers Association organized a letter from more than 3,200 bankers urging the Senate to act. The commercial logic is transparent on both sides: yield-bearing dollar tokens pull retail deposits off bank balance sheets, while for exchanges, per the CRS analysis, distributing that yield has become one of the largest growth lines in the business. In its proposed rule, the OCC included a rebuttable presumption that any coordinated arrangement between an issuer and an affiliate or related third party to pay holders yield is itself a prohibited yield arrangement — a formulation that, according to the CRS brief, reflects banking-side lobbying outweighing exchange-side lobbying at the agency. The comment period closed May 1, 2026; banking trade groups requested an extension and the OCC declined.

The outcome matters enormously for the competitive map. If the yield loophole closes entirely, OUSD’s model of routing reserve earnings to business adopters — rather than to retail holders — may become the only compliant way to share economics, strengthening the consortium’s pitch. If the loophole survives, Coinbase’s USDC rewards program remains a powerful distribution weapon for Circle. Either way, the rule-writing now underway in Washington will pick winners.

What Comes Next: A Market Redrawn, Not Yet Decided

It is tempting to read this week’s headlines as the beginning of the end for Circle’s model, but the honest assessment is more conditional. OUSD is still pre-launch; consortium projects have a long history of dying between announcement and issuance, and 140 partners means 140 sets of competing incentives. USDC retains deep integrations, regulatory standing, and a still-growing $75-77 billion float. Tether’s dominance has survived every previous challenger. RLUSD’s rise is real but starts from a base — under $1 billion — that is a rounding error next to the majors, and its most impressive statistics come from Ripple-aligned research.

The variables to watch over the next two quarters are concrete: whether Open Standard actually ships a live token and discloses who will serve as its permitted issuer under the GENIUS Act; whether the OCC’s final rule adopts, softens, or expands the rebuttable presumption against third-party yield arrangements; whether Congress moves separately to amend the statute as bank lobbyists want; and whether Circle responds by restructuring how it shares reserve economics with partners. If the past two years are any guide — a market that nearly doubled to $315 billion while its legal foundation was rewritten — the only safe prediction is that the stablecoin wars will not be settled by a single announcement, however many logos are attached to it. The prize, a share of the interest on hundreds of billions of reserve dollars and a claim on the future of dollar payments, is large enough that every incumbent and every challenger will keep fighting for it.
