The ECB warned EU finance ministers that proposals to issue more euro stablecoins could reduce bank lending and make controlling interest rates harder

The European Central Bank just threw cold water on euro stablecoin ambitions. In a warning delivered to EU finance ministers on Friday, the ECB flagged serious concerns about proposals to ramp up euro-denominated stablecoin issuance.

The core worry: more euro stablecoins circulating in the wild could siphon deposits away from traditional banks, shrinking their capacity to lend. That's a problem. Less bank lending means less transmission of monetary policy decisions into the real economy.

It gets worse. The ECB also warned that a surge in stablecoin usage could make controlling interest rates significantly harder — essentially blunting one of the central bank's most important tools.

The warning lands as EU policymakers weigh how aggressively to support homegrown stablecoin projects, partly to counter dollar-pegged tokens dominating the market. The ECB's message is clear: move carefully, or risk breaking the plumbing.
