ECB Supervisory Chief Warns Europe Against Loosening Bank Capital Rules
nashnova research
ECB supervisory board chair Claudia Buch warned that Europe must not weaken bank capital standards for short-term gains, calling the current deregulation drift a "tail risk" — this signals a deepening internal rift over whether to follow the U.S. in easing bank rules.
What exactly is Buch worried about?
Speaking in Frankfurt, Buch said the current regulatory debate carries a risk of sliding into deregulation. She hopes it is "only a tail risk."
Tail risk — a low-probability event with severe consequences. Her word choice signals: loosening is not the base case, but if it happens, the damage is hard to reverse.
This reflects the ECB supervisory arm's wariness of political pressure: once standards are lowered, raising them again is politically near-impossible.
Why do banks want looser rules?
European banks are pushing to cut capital requirements for two reasons: to compete with U.S. and Asian peers, and to free up capital for lending.
The backdrop: the U.S. is already reviewing bank-rule rollbacks. European banks fear an unlevel playing field.
In plain terms = banks feel they are forced to keep too much cash on the sidelines and lend out too little.
How does Buch push back?
Her core argument: well-capitalised banks are actually better lenders — holding enough capital is not a constraint but a foundation.
She cited recent research showing that capital requirements across major economies are broadly comparable and are not the key drag on bank performance.
This means → the claim that "high capital requirements hurt competitiveness" does not hold up well in the data.
What really drives bank competitiveness?
Buch argued the real drivers are three structural factors: technology adoption, scale, and operational efficiency.
In plain terms = whether a bank makes money depends mainly on how well it digitises and manages costs — not on how loose the rules are.
She added that the upcoming regulatory review is "very valuable," but should aim to make the system stronger and more integrated while preserving resilience — not simply to loosen it.
