About this report

Germany is undertaking a radical transformation of its fiscal and strategic posture, marked by a projected increase in core defence spending from €95 billion in 2025 to €162 billion by 2029—equivalent to 3.5% of GDP.

This acceleration outpaces comparable plans in France and the UK, positioning Germany as the new leader among European NATO members in meeting the proposed alliance-wide target of 5% (3.5% core military, 1.5% cyber and infrastructure). Central to this shift is a constitutional reform that allows defence expenditures exceeding 1% of GDP to be financed outside the traditional debt brake, enabling up to €1 trillion in borrowing over the next decade.

Key questions this report answers

• How does Germany's planned rise in core defence spending from €95 billion in 2025 to €162 billion by 2029 translate into its 3.5% of GDP target?
• How does the constitutional reform exempting defence spending above 1% of GDP from the debt brake enable up to €1 trillion in borrowing over the decade?
• How does Germany's trajectory compare with France and the UK in meeting NATO's proposed 5% target split into 3.5% core military and 1.5% cyber and infrastructure?
• What are the fiscal consequences of this spending surge for German borrowing, deficits, and debt service over the coming years?
