The Ukraine war and geopolitical tensions pose major challenges for supply chains. Whereas shortages of microchips became a symbol of supply chain disruptions during Covid-19, a survey from June 2022 from the ifo Institute shows that over 74% of German manufacturing firms report production disruptions due to shortages of different types of inputs and raw materials. The production of key technologies that are necessary, for instance for the energy transition, often depends on imported raw materials. Therefore, it is important to evaluate Germany’s raw material dependencies at the product level to identify the risk of future supply chain disruptions. This paper identifies nine critical raw materials, which have a high degree of supplier concentration and are used in more than half of the key technologies. For these raw materials, we provide a detailed analysis on Germany’s dependency on imports.

This article discusses the economic effects of a potential cut-off of the German economy from Russian energy imports. We show that the effects are likely to be substantial but manageable. In the short run, a stop of Russian energy imports would lead to a GDP decline in range between 0.5% and 3% (cf. the GDP decline in 2020 during the pandemic was 4.5%).

The Great Financial Crisis caused a deep recession and led to very large public deficits. When financial market tensions erupted, many European countries were forced to reduce their deficits. This ‘austerity’ is often credited with the disappointingly slow recovery during the years after the financial crisis. One reason for such a slow recovery could have been that the impact of a reduction in the fiscal deficits is larger than anticipated during a recession, especially if it is accompanied by financial market tensions. At the height of the financial crisis and in its immediate aftermath, this might not have been properly taken into account.
