Germany’s lower house of parliament, the Bundestag, has approved the federal government’s 2026 budget, clearing the way for what officials describe as a historic level of public investment. The financial plan, passed on Friday, raises expenditures to 524.5 billion euros, slightly higher than the amount proposed earlier this year. Much of the increase is directed toward boosting investment as Berlin seeks to revive the country’s weakening economic momentum.
Since taking office in May, the government has made public investment the cornerstone of its strategy to stimulate growth. While the initial optimism has faded due to delays in implementation and broader economic uncertainty, coalition leaders remain confident that the measures will help lift Germany’s economy next year. The focus on investment reflects growing concerns over aging infrastructure, slow productivity growth, and the need for rapid modernization in sectors such as energy and transportation.
The budget allocates 58.4 billion euros of direct spending to public investment. When additional off-budget funds are included, such as the Climate and Transformation Fund and a new infrastructure financing mechanism, total investment is expected to reach roughly 126.7 billion euros in 2026. This would mark the second year in a row that federal investment hits a record high, following an unprecedented peak in 2025. The government’s medium-term plan projects sustained investment of about 120 billion euros annually from 2027 through 2029.
Despite the budget’s approval by a vote of 322 to 252, it has provoked strong debate in German politics. Opposition parties argue that the spending increases fail to adequately target the country’s most urgent needs. The Greens, despite being traditionally supportive of investment, criticised the budget for prioritising campaign commitments rather than channelling funds into critical upgrades, particularly in infrastructure and public services.
The Alternative for Germany party went further, calling for a substantial reduction in overall spending. The party proposed lowering expenditures to 505.8 billion euros and cutting defence spending to accelerate Germany’s return to strict debt brake rules. AfD lawmakers warned that rising debt levels and increasing interest obligations could undermine long term fiscal stability.
According to government projections, interest payments are expected to remain around 30 billion euros in both 2025 and 2026 before rising sharply to 66.5 billion euros by 2029. Analysts say this jump reflects the combination of higher borrowing costs and expanding deficits. Over the 2027 to 2029 period, cumulative fiscal gaps are forecast to reach 172 billion euros, raising concerns among economists about the sustainability of Germany’s public finances if borrowing continues to grow.
The government counters that strong investment is essential to securing future growth, arguing that infrastructure upgrades, energy transition programmes and digital transformation projects will pay long term dividends. Officials insist that cutting spending at this stage could worsen economic stagnation and delay essential reforms.
As Germany prepares for 2026, the approved budget signals a continued push toward large-scale investment while acknowledging the mounting debt challenges ahead. Balancing growth ambitions with fiscal discipline will remain one of the central debates in German politics over the coming years.
