MadridDollar stablecoins hit $310bn; 2 firms hold 90% of that market.
European Central Bank chief Christine Lagarde warned US-issued stablecoins risk “digital dollarisation” of European payments if dollar rails dominate.
The bank targets a digital euro by 2029; a 12-bank consortium plans a rival private version this year.

WHAT DOLLARISATION ACTUALLY MEANS
When a foreign currency displaces the local one for everyday transactions and savings, the central bank loses its main policy lever. It can no longer set interest rates that bite, no longer print to fight a downturn, no longer earn seigniorage on the money in circulation. Ecuador, El Salvador, and Zimbabwe learned this the hard way — once dollars are entrenched, the local monetary authority becomes ceremonial.
WHY STABLECOINS ARE A NEW VECTOR
Historic dollarisation required physical dollars or dollar bank accounts — both gated by US banks. A dollar stablecoin sits on a public blockchain, transfers in seconds, and reaches anyone with a phone. The friction that protected non-dollar economies from currency substitution has effectively collapsed.
THE TWO-FIRM PROBLEM
Tether (USDT) and Circle (USDC) issue the overwhelming majority of dollar stablecoins in circulation. Their reserves are mostly short-dated US Treasuries — making the duo, in aggregate, one of the larger holders of US government debt globally. The market is not decentralised; it is a duopoly with a sovereign-debt feedback loop.
WHAT A CBDC ACTUALLY IS
A central bank digital currency is a direct liability of the central bank — like a banknote, but digital. It bypasses commercial banks for the final settlement step, which is why banks across Europe have lobbied hard against the digital euro: it threatens deposits, the cheap funding that keeps lending profitable.
THE EURO'S RESERVE-CURRENCY GAP
The dollar accounts for roughly 58% of global FX reserves; the euro sits near 20%. That gap has barely moved in two decades despite the eurozone matching the US in economic size. Network effects in payments are extraordinarily sticky — once invoicing, debt issuance, and oil pricing settle on a currency, displacing it requires a generational shock.
THE 2029 DEADLINE
The ECB has been studying a digital euro since 2020. A 2029 launch would put it years behind China's e-CNY, which has been in pilot since 2020 and processed hundreds of billions of yuan in transactions. The lag is not technical — it is political: privacy, bank disintermediation, and offline functionality are all unresolved.
