Central banks split over stablecoin risks

TLDR

Central bankers increasingly disagree on whether stablecoins are a useful payment innovation or a structural threat to money and banks.

1. U.S. Federal Reserve voices highlight potential benefits and dollar reach, while European officials warn of stability and policy risks.
2. Key concerns focus on bank runs, loss of deposits, weaker monetary policy tools, and reinforcing U.S. dollar dominance via dollar-pegged stablecoins.
3. This split is shaping very different rulebooks, from U.S. stablecoin bills to Europes digital euro and strict MiCA-style regimes.

Deep Dive

1. Who Is On Each Side

At a recent Dubrovnik conference, Fed governor Christopher Waller called stablecoins a payment instrument with nothing evil about them and argued they add competition and can lower costs in payments. He also said widespread use of dollar-backed stablecoins could extend the reach of U.S. monetary policy abroad, as other countries import U.S. conditions through these tokens.

By contrast, Bank of England policymaker Megan Greene said she expects tokenized bank deposits to overtake stablecoins within about five years, arguing that banks will push their own digital deposits once fee income comes under pressure. She warned that stablecoins are not so stable, face regulatory gaps, and can facilitate illicit activity.

European Central Bank board member Isabel Schnabel has gone further, saying stablecoins pose significant risks to financial stability and monetary policy and that the best response is to ensure public money and a digital euro remain the anchor of the system.

2. What Risks And Tradeoffs They See

Schnabel and other European officials warn that stablecoins can:

1. Speed up bank runs by letting deposits flee banks instantly in a stress event.
2. Weaken the main central bank tool, the interest rate channel, if deposits shift into stablecoins outside traditional banking.
3. Reinforce U.S. dollar dominance because most major stablecoins are dollar-pegged, potentially eroding the role of the euro and other currencies.

Greene adds worries about regulatory uncertainty and illicit finance, and notes that stablecoins can drain deposits that currently support bank lending. Waller accepts some of these issues but emphasizes competition and innovation in payments and sees regulated stablecoins as compatible with dollar leadership.

3. How This Shapes Rules And Markets

In the U.S., this debate feeds directly into legislation such as the CLARITY Act, where a major fight is whether stablecoin issuers can offer yield-like rewards on balances, something bank lobbyists say could destabilize deposits. Outcomes here will decide if stablecoins look more like bank deposits or narrow payment tokens.

In Europe, the ECB and EU lawmakers are building a digital euro and MiCA-style regimes that place strict reserve, redemption and usage rules on stablecoins, and may cap their scale to protect banks and policy transmission. Some officials even see large dollar stablecoins as a strategic risk to European monetary sovereignty.

Conclusion

Central banks are converging on the idea that stablecoins matter for the core plumbing of money, but they disagree on whether they are mostly useful competition or mostly systemic risk. That split is producing diverging regimes, with the U.S. flirting with stablecoin-friendly rules and Europe prioritizing control, bank stability, and a digital euro. For crypto participants, tracking which jurisdictions land on which side of this debate will be key to understanding where stablecoin growth, and related crypto activity, can scale most easily.
