€3,000 Digital Euro Cap Spares Banks From Deposit Drain, Bundesbank Says

Germany's Bundesbank has a number for the digital euro debate: €3,000 per person. A holding limit at that level would inflict only minimal damage on European banks' long-term health, according to a study the central bank published this month.

The core worry around any central bank digital currency has always been bank deposits. If households shift savings from commercial banks into a state-backed digital wallet, lenders lose the funding they use for mortgages and corporate loans. The Bundesbank ran the numbers and concluded a €3,000 cap keeps that risk small. The paper calls the expected effect on bank funding "muted." The analysis found the limit would prevent any large-scale deposit migration, letting institutions adjust gradually rather than scrambling to plug a funding hole overnight.

The cap targets small savers by design. At €3,000 per individual, the digital euro won't attract the kind of money that funds lending. Businesses and wealthier households park far more than that in bank accounts. The limit walls off the digital euro from becoming a direct substitute for deposits banks actually depend on. The Bundesbank's analysis frames that as the whole point: keep adoption manageable, protect lending capacity, and let the European Central Bank introduce the currency without destabilizing the financial system.

A trade-off exists, and the study acknowledges it. A €3,000 ceiling limits how disruptive the digital euro can be to banks – it also limits how widely the currency gets used. The Bundesbank's researchers say the overall impact depends heavily on adoption rates and public perception. If uptake is slow, the cap barely matters. If uptake is fast and enthusiastic, the cap does real work keeping deposit outflows in check. Either way, the ECB will need to monitor closely and stay ready to adjust, the researchers said.
