Short-term Economic Effects of a "Brexit" on the German Economy
Many questions about Brexit remain open. It is still possible that the UK and the European Union will not be able to agree on a withdrawal agreement. In this case a so-called hard Brexit (No-Deal Brexit) would happen. We have examined the short-term effects of a hard Brexit for the German economy. In a first step, effects via the trading channel are estimated based on an input-output analysis of international and sectoral links. The result is a loss of 0.3% relative to gross domestic product. This magnitude also results from the international Halle Economic Projection Model, which takes into account macroeconomic repercussions. A hard Brexit would, in addition to the trade barriers, mean significant uncertainty for firms and households. On the demand side, this has a negative impact on investment activity and private consumption. Taken alone, these effects amount to 0.1% of gross domestic product. Overall, German gross domestic product could be dampened by several tenths of a percentage point in the one to two years following a hard Brexit. The automotive industry would probably suffer most. However, recommendations for discretionary economic policy measures aimed at dampening short-term macroeconomic effects or at individual economic sectors cannot be derived from this. The automatic stabilizers are sufficient given the expected magnitude of the effects.
