Germany is embarking on a significant spending increase, particularly in infrastructure investment and defense, which is poised to drive its debt-to-GDP ratio from an expected 62.8% at the end of 2025 to approximately 71% by 2030. This projection, made by Scope Ratings, comes after amendments to Germany's constitutional debt brake. Despite this rise, the projected 2030 debt level remains well below the 81% peak observed in 2010 following the global financial crisis, indicating that Germany has built up fiscal space over previous years.
However, Scope Ratings highlights that sustaining its AAA credit rating in the long term will necessitate structural reforms beyond merely increasing borrowing. The current fiscal framework, anchored by the constitutional debt brake, has historically contributed to Germany's strong credit profile. Yet, increasing expenditures on interest payments, social security, pensions, and healthcare are expected to reduce fiscal flexibility over time. Scope analyst Julian Zimmermann noted that despite rising borrowing, pressure to consolidate the government's core budget will increase.
Germany's medium-run growth potential is also a concern, estimated at around 0.8%, falling short of its AAA-rated peers and other large economies. While an infrastructure fund of EUR 500 billion could boost growth potential to 1% from the current 0.7%, the growth impact from increased defense spending is expected to be more moderate. To maintain fiscal maneuverability, particularly as the proportion of available funds in the federal budget is projected to drastically fall, structural reforms in areas like pensions and the labor market are deemed necessary. Challenges also include an aging population, transition risks related to carbon neutrality, and increased competitiveness for German exporters in global markets.
Proposed reforms to the debt brake, such as excluding net investments or establishing a constitutionally anchored special fund for green and digital transformation, are being discussed. These changes aim to encourage long-term investments that could support future growth and competitiveness. However, any amendment requires cross-party political support, as it involves changing the German Basic Law. The stable outlook on Germany's AAA rating reflects Scope's assessment that risks over the next 12 to 18 months are well balanced, provided the country addresses these long-term fiscal and structural challenges.
