Stablecoins are rapidly becoming one of the dominant use cases linking crypto and tradfi.
Recent forecasts, institutional moves, and regulatory efforts suggest the sector is reaching an inflection point. And now, at least one analysis believes the stablecoin market cap alone could reach $4 trillion by 2030.
That’s twice the current size of the entire crypto economy in stablecoins alone.
If stablecoins were to be integrated everywhere, the analysts suggest they could support as much as $100T of annual transaction volume, a scale dwarfing today’s markets.
The biggest real opportunity is in cross-border settlement, where inefficiencies still exist. Even so, Citi highlights that tokenized bank deposits may surpass stablecoins in usage by 2030.
Bank tokens are tokenized deposits, deposit tokens, and other bank-issued tokenized assets. They provide the trust, familiarity, and regulatory safeguards of bank money, and many corporations prefer them over stablecoins.
The current stablecoin market grew from around $200B in early 2025 to nearly $280B, despite experiencing significant market swings. Governments and regulators are actively discussing how to regulate the issuance, backing, and redemption of these asset instruments.
Beyond market risk, stablecoins carry macro and geopolitical stakes.
The more stablecoins proliferate, the more issuers will likely hold U.S. Treasuries as reserve backing.
This creates a strategic vulnerability for Europe: a foreign digital currency could undermine domestic monetary control.
In response, nine European banks — including UniCredit, ING, CaixaBank, SEB, and Raiffeisen — have teamed up to launch a euro-denominated stablecoin, aiming for a debut in late 2026.
The stablecoin project aligns with the enforcement of the EU’s MiCA regulation and complements efforts by the European Central Bank to push forward a digital euro.
There’s a bit of urgency to the project – the dominance of U.S. dollar tokens could erode monetary control and expose Europe to external leverage. U.S. stablecoin incumbents like Tether ($USDT) and Circle ($USDC) already command massive network effects and liquidity.
For the European project to succeed, it must overcome regulatory barriers, build trust, and provide liquidity – and fast.
