The international political environment has fundamentally changed with looming trade wars and a deteriorating security situation in Europe. The leading parties in Germany are setting the stage for debt-financed additional defence tasks with far-reaching changes to the debt brake. This entails major risks for the German economy, but also opportunities.
Meanwhile, the economy continues to be in a downturn. According to the spring forecast of the Halle Institute for Economic Research (IWH), gross domestic product (GDP) in 2025 is likely to be roughly the same as in the previous year, and it will not increase significantly until 2026, partly because uncertainty about German economic policy is likely to decrease after the new government is established, meaning that the savings rate of private households will fall again somewhat and the debt-financed additional government spending will gradually have an impact on demand.
The IWH economists are forecasting an increase in GDP of 0.1% for 2025. In December, they were still forecasting growth of 0.4% for 2025. The outlook is similar for East Germany, where production is likely to have increased slightly in 2024, unlike in Germany as a whole.

The announcements and decisions made by the new US administration, particularly regarding its position in the Russia-Ukraine conflict and its tariff policy, have led to high uncertainty worldwide and recently caused US share prices to fall significantly. Meanwhile, the global economy is likely to have continued expanding moderately during winter. The economy remained robust in the US, but weak in the euro area. In the US, the negative effects of economic policy uncertainty and higher tariffs are likely to roughly balance out the short-term positive effects of deregulation. In China, the property crisis is continuing for the time being, while the success of the DeepSeek chatbot app has improved the outlook for the Chinese tech sector. In the euro area, the economy will remain weak in 2025.

In Germany, CDU/CSU and SPD have agreed to de facto suspend the debt brake in order to finance rearmament and additional public infrastructure investments. “The additional public spending should gradually have a stimulating effect on the economy,” says Oliver Holtemöller, head of the Macroeconomics Department and Vice President at the IWH.
Private households are adapting to the economic crisis by being more cautious with their spending: their savings rate is at present significantly higher than the long-term average. In this forecast, we assume that the infrastructure fund will indeed be set up and that military spending will be significantly higher. However, all this will hardly have any real economic impact in the current year, but only in later years. In addition, the sharp rise in social security contributions has a negative impact on disposable income. “All in all, gross domestic product in Germany is likely to stagnate in 2025, as will the number of employed persons,” says Oliver Holtemöller. The general government budget deficit is likely to amount to 2.7% in 2025 and rise to 3.2% in 2026.
