From the very beginning, the Schoeller wholesale business carried out banking transactions, initially for its own purposes and its own companies, but soon also for third parties.

[3] Alexander von Schoeller used his banking profits to invest in industrial activities which quickly became extensive.

The main task of the banking department was to finance industrial operations, handle the group's commercial relations and payment transactions.

The group and its industrial holdings were always geared towards the monarchy as a whole, and the domestic market was fragmented into a number of protectionist countries.

[4] The wholesale business, which had been very important until the end of the Danube Monarchy, could not continue to operate after 1938 due to the National Socialist Banking Act.

When the Battle of Vienna was won in mid-April 1945, the Red Army occupied the city and the bank was placed under public administration, which was lifted on April 1, 1948.

[4] After the end of World War II, the bank had to change its business policies because its partners in Germany were temporarily unable to act due to strict foreign exchange control and interruptions in business relations with the countries behind the Iron Curtain.
