Germany faces massive interest payment increases through 2031

Rising interest rates are projected to impose significant financial burdens on the German federal government. According to a simulation by economist Friedrich Heinemann of the Leibniz Centre for European Economic Research (ZEW), the interest rate hikes since last year will cost taxpayers an additional 58 billion euros in interest payments over the next five years, assuming rates remain at current levels.

Heinemann warns that a further increase of 100 basis points could raise the interest burden by an additional 71 billion euros by 2031. He notes that Germany is entering a period of rising interest costs similar to the 1980s and 1990s, but suggests that current economic conditions may prevent the country from growing out of the situation, potentially necessitating spending cuts.

Furthermore, the economist cautioned that Germany risks losing its AAA credit rating. He pointed out that national debt is expected to rise to approximately 2,862 billion euros by the end of the decade, an increase of 1,000 billion euros compared to 2025. Heinemann stated that if new debt is not used for fundamental infrastructure renewal, maintaining the top-tier rating becomes unlikely.
