It is in the nature of things that bankers and their supervisors do not always agree.
But the two sides have seldom expressed their displeasure with one another as openly as these days.
The bankers are happy that they can finally record bubbling profits again in view of the rising interest rates all over the world and do not want to let their mood be spoiled by overly cautious supervisors.
Once before, namely during the Corona crisis, the regulators made life unnecessarily difficult for the banks with their fear of the next financial crisis, they think.
And at the same time warn that stricter requirements, for example on capital resources, could make lending more difficult in a troubled economy.
From today's perspective, we know that the fear was exaggerated back then - but afterwards we are always smarter.
The fact that the Corona crisis ultimately hardly affected the banks was mainly due to the lavish state aid for their customers, from short-time work benefits to emergency loans and special regulations for filing for bankruptcy.
Banking supervisors have the difficult task of recognizing and eliminating their weaknesses as early as possible and, if possible, together with the banks.
The fact that the supervisors are now warning with increasing frequency that the banks are not taking the potential dangers of the crises seriously enough does not exactly inspire confidence.
