In the UK the central bank acts through a certain small number of money centers which are large systemic banks, which act as primary dealers, while in the case of Germany the central bank has contacts with every single small bank and every single small bank feels also entitled to be part of this national framework.
When we defined European monetary policy, we had to bridge these differences and invent compromises between the two. As a result we have centralized decision-making, but decentralized preparatory work and also decentralized implementation of decisions. The different views of the role of the individual and the collectivity are also reflected in our legal systems, which are very different.
