The long-term economic impact of the United Kingdom's withdrawal from the EU on German companies will largely depend on what the future relationship between the United Kingdom and the EU looks like.

A study by the Ifo-Institute commissioned by the Economic Affairs Ministry is examining a total of eight different scenarios of what future relations between the EU and the United Kingdom could look like, and their impact on the German and European economy. The findings of the study show that Brexit will have economic repercussions for the EU Member States and especially for the United Kingdom. However, even in the most unfavourable scenario, the overall impact of Brexit on the EU economy and the German economy in particular, ought to be manageable. You can find the study (in German) here.
