This sector can be subdivided into the banking, insurance and finance sectors.

The banking, insurance and financial sectors have in common the daily handling of numbers and money. Similar to other industries, a distinction is made here between activities with direct customer contact (B2C) and contact only with business customers (B2B). In addition, there is a large proportion of purely administrative activities in this sector, i.e. without direct customer contact.

While in the banking sector the primary focus is on money management and investment, in the insurance sector there is also the active sale of insurance policies to private individuals and companies. The financial sector in general consists mainly of service providers with special specialisations, such as individual financial optimisation.

Since banks and insurance companies in particular have high government requirements, there are correspondingly many public control bodies that also fall into this sector in a certain way, since they employ employees with similar qualifications.

There are, for example, bank clerks or insurance clerks as training courses; dual courses of study, e.g. banking business administration, are becoming more and more popular. Possible courses of study are economics, finance and business administration, business mathematics or other economic sciences.
