Three days ago, the stablecoin market changed. Not gradually. Not incrementally. Tuesday’s announcement hit Circle’s stock for 17% in a single session and exposed something the financial press is mostly describing wrong.
Here’s what actually happened.
The Real Story Behind Open USD
A coalition of more than 140 companies — including Visa, Mastercard, Stripe, Coinbase, BlackRock, BNY, Standard Chartered, Google, Shopify, and Ripple — announced the formation of Open Standard and a new dollar-pegged stablecoin called Open USD, or OUSD. The stablecoin market has grown to more than $300 billion, and Citi projected it could reach $4 trillion by 2030. That’s the number Wall Street is citing. The number they’re skipping is more interesting.
Both Circle and Tether park stablecoin backing in short-term U.S. Treasuries and keep the yield themselves. Open USD proposes to share that yield with its distribution network instead. That’s not just a competitive product. That’s a direct attack on the entire economics of the existing business model.
Slight tangent, but it matters: stablecoin aggregate transaction volume hit $33 trillion in 2025, a 72% year-over-year increase — with USDC alone processing $18.3 trillion, more than Visa’s $15.7 trillion in payment volume over a comparable period. The infrastructure already works at scale. The question has always been who captures the economics. Tuesday was the answer.
What People Are Missing
Stripe has committed to making OUSD the default stablecoin for businesses on its platform. Visa and Mastercard together touch the majority of global card-based transactions. That’s not a typical competitive threat. Tether and Circle solved the engineering years ago. Their problem was always distribution — getting into the checkout, into the bank’s payment stack, into the merchant’s settlement flow.
That’s precisely what Visa and Mastercard own outright. Visa already runs more than 130 stablecoin-linked card programs across over 50 countries and settles across nine blockchains. They don’t need to build trust. They already are the trust layer.
The part that’s quietly buried: Coinbase, Circle’s single most important distribution partner, is on the OUSD partner list — while its $908 million-per-year commercial agreement with Circle comes up for renewal in approximately August 2026, as Circle’s IPO filing disclosed. Think about the timing there.
Who Benefits. Who Doesn’t.
Circle is the obvious loser in the headline read. The stock closed below $63, down 55% from its mid-May peak. Some analysts called the selloff an overreaction — and they may have a point about timing, since OUSD won’t launch until later in 2026 and the reserve-yield routing model may face legal friction under the OCC’s proposed GENIUS Act implementation rules.
The less obvious winners are the ones nobody is watching yet. JPMorgan, Bank of America, Citigroup, and Wells Fargo have begun exploring a joint stablecoin initiative routed through Early Warning Services, the operator of Zelle, and The Clearing House, which powers real-time payment networks. If OUSD normalizes the consortium model, the major banks get their entry point without the reputational overhang of going it alone.
The deeper implication for traditional finance may be the one that takes longest to price. Standard Chartered’s global head of digital assets research estimated that stablecoins could drain roughly $100 billion from U.S. bank deposits, with Citigroup’s analysis projecting between $182 billion and $908 billion in deposit displacement by 2030. That’s not a digital asset story. That’s a banking system restructuring story wearing a crypto headline.
The $300 billion market is just the opening bid.
