Compliance with the EU fiscal rules requires extensive consolidation – Medium-term projection of macroeconomic developments and public finances in Germany
Germany faces considerable structural burdens from both macroeconomic and fiscal perspectives, as potential growth is likely to be significantly lower than in past decades. A projection by the Halle Institute for Economic Research (IWH) on macroeconomic developments up to the year 2040 shows that, under unchanged fiscal policies, public debt can be expected to continue rising. The federal government's fiscal-structural plan assumes compliance with EU requirements, but this is only achievable under the assumption of high global spending cuts that have not yet been specified in detail.

Abstract
Der Beitrag untersucht die mittelfristige Entwicklung der deutschen Wirtschaft und der öffentlichen Finanzen vor dem Hintergrund der seit 2025 geltenden neuen EU-Fiskalregeln und der jüngsten Lockerung der nationalen Schuldenbremse. Im Mittelpunkt steht die Frage, ob und unter welchen Bedingungen Deutschland die europäischen Vorgaben zu Defizit, Schuldenstand und Nettoprimärausgaben einhalten kann.

Medium-term projection for the German economy and scenarios for achieving the targets of the Climate Protection Law
The potential growth rate of the German economy is declining. According to the medium-term projection of the Halle Institute for Economic Research (IWH), potential output is likely to increase by an annual average of just 0.3% in the medium term (2023-2029). The target of climate neutrality by 2045 is likely to be missed by a wide margin without further emission-reducing measures. It could be achieved by means of higher CO₂ prices at significantly lower macroeconomic costs than by means of non-market-based regulatory measures.

Green transition and the debt brake: Implications of additional investment for public finances and private consumption in Germany
The German Climate Protection Act stipulates, among other things, that greenhouse gas emissions in Germany are to be reduced by 65% by 2030 compared to 1990 levels. The green investments required to achieve this target are likely to amount to around 2.5% of gross domestic product each year. According to the medium-term projection of the Halle Institute for Economic Research (IWH), the associated additional government spending on public investment and support measures cannot be financed from projected tax revenues. It is therefore to be expected that the tax burden on households will increase and private consumption will be curbed accordingly, if both the current form of the debt brake and the greenhouse gas reduction targets are maintained.
