The European Union is considering walking away from a key piece of post-crisis banking regulation, and the former head of the Basel Committee on Banking Supervision isn't mincing words. He calls the potential move a disaster.
The output floor, explained
At the center of the fight is the output floor, a rule that sets a minimum capital level for banks regardless of what their internal risk models say. After the 2008 financial crisis, regulators wanted to stop banks from using those models to shrink their capital requirements to dangerously low levels. The output floor was meant to be a backstop—a way to ensure that even the most optimistic bank still holds enough money to absorb losses.
The rule was part of the Basel III framework, a global set of standards that took years to negotiate. The EU signed on, but now it's reportedly having second thoughts. The bloc hasn't formally announced a decision, but the possibility that it might relax or abandon the output floor has already drawn sharp criticism.
Why the EU's retreat matters
The former Basel chief didn't just call the move a disaster. He warned that relaxing the output floor could undermine global regulatory cohesion. That's not a small concern. If the EU goes its own way, other jurisdictions might follow, and the carefully aligned rules that govern international banks could start to fray.
That would complicate things for banks that operate across borders. They'd face different capital requirements in different markets, making it harder to plan and manage risk. It could also open the door to regulatory arbitrage—banks shifting activities to places with looser rules. Over time, that could build up hidden risks in the system, the kind that tend to surface all at once.
A break from global consensus
The EU's potential move is a test of whether the post-crisis consensus holds. The Basel framework was built on the idea that banks everywhere should play by roughly the same rules. If the EU, one of the biggest banking markets in the world, decides the output floor is too burdensome, it sends a signal that the global standard isn't as solid as it seemed.
The former Basel chief's warning is a direct challenge to that thinking. He's not alone in worrying about the consequences, but he's the one who said it plainly: this would be a disaster. The EU hasn't responded publicly, and it's unclear when a final decision will come. What's certain is that the stakes are high, and the clock is ticking.
