The report examines the potential economic impacts on Germany of a complete and permanent shutoff of Russian natural gas supplies to Europe. The authors consider the curtailment of flows through the Nord Stream 1 pipeline and the potential impact on Germany's industrial production, trade, and inflation. The report also discusses the potential for Germany to diversify its gas supplies and the potential for increased energy security. The authors acknowledge the potential for significant economic disruptions and recommend policy measures to mitigate the impact.
