Warum der Baseler Ausschluss für Bankenaufsicht mit seinem antizyklischen Kapitalpuffer falsch liegt


  • Ludwig, Björn


Das Basel III Rahmenwerk führt einen antizyklischen Kapitalpuffer, um das durch die Krise eindrucksvoll bestätigte Problem der Prozyklizität der Eigenkapitalanforderungen zu lösen. Das Entscheidungskriterium zu Abgrenzung der konjunkturell guten Phase von der schlechten Phase, das den Kapitalaufbau beziehungsweise Kapitalabbau begründen soll, basiert auf dem Verhältnis vom nominellen Kreditvolumen zum nominalen BIP. Anstelle das Problem der Prozyklizität zu lösen, wird der in dieser Form von der Bankenaufsicht konzipierte antizyklische Kapitalpuffer bei einer regelgebundenen Anwendung das Problem eher verschärfen, denn in konjunkturell schlechten Zeiten mit niedrigem BIP Wachstum signalisiert der Indikator die Erhebung des zusätzlichen Kapitalpuffers und in konjunkturell guten Zeiten mit einem hohen BIP Wachstum nicht. Anstelle dieser Konzeption sollte besser das Kreditwachstum und der Kreditimpuls als Entscheidungskriterium verwendet werden, da bei diesen Größen ein hinreichend guter Zusammenhang zum Wachstum des realen BIP besteht.
