The ECB may wish to exercise its supervisory discretion and require more capital even when minimum pillar 1 requirements are met, such as through Pillar 2 charges, stress test results or maybe even accelerated CRDIV implementation.
Overall, I do not see any risk of "excessive tightening" at the moment: transmission is running smoothly and monetary policy is having the right impact. So, this brings the "inspection" that I mentioned at the start of my speech to a close.
