2025 debt brake reform and the €500bn infrastructure and climate neutrality fund
The constitutional amendment of 22 March 2025 exempts from the debt brake the defence and security spending above 1% of GDP, gives the Länder as a whole a structural borrowing margin of 0.35% of GDP and allows a special fund of up to €500bn, financed by borrowing outside the debt brake, for additional investment in infrastructure and climate neutrality by 2045. The SVIKG act set up the fund from 1 January 2025: €100bn for the Länder, €100bn for the Climate and Transformation Fund, investments approved until the end of 2036.

Implementation
- Federal Ministry of Finance — manages the special fund
- Bundestag — yearly federal budget and the fund’s economic plan
- The 16 Länder and their municipalities — €100bn share and structural borrowing margin
Stated objective
Finance a lasting build-up of the Bundeswehr in response to a « fundamental change in the security architecture », catch up on the investment backlog in infrastructure through an « investment offensive » meant to strengthen medium-term growth, finance additional investment towards climate neutrality by 2045, and give the Länder room to borrow in view of the « challenging financial situation of the Länder and municipalities ».[5]
According to the explanatory statement of the SPD and CDU/CSU bill and the amendment adopted in the Budget Committee
Maximum volume of the special fund
€500bn
investments approved over 12 years · according to Article 143h of the Basic Law and the SVIKG act[4][17]
Structural borrowing margin of the Länder as a whole
0.35% of GDP
each year, from 2025 · according to Article 109 of the Basic Law; before the reform, the Länder could not borrow structurally[2][21][11]
Main measures
- Defence and security exemption: the federal borrowing counted under the debt brake is reduced by the amount by which spending on defence, civil protection, intelligence services, the protection of IT systems and aid to states attacked in breach of international law exceeds 1% of nominal GDP. No ceiling and no time limit.[3][1][11]
- The ordinary federal rule is unchanged: structural borrowing up to 0.35% of GDP plus the cyclical component; the emergency clause remains.[3]
- Special fund « Infrastructure and Climate Neutrality » with its own borrowing authority of up to €500bn, outside the debt brake: €100bn for the Länder, €100bn paid to the Climate and Transformation Fund in ten equal yearly tranches until 2034, the rest for federal investment in civil protection, transport, hospitals, energy, education and childcare, research, digitalisation, housing and sport.[4][17][23]
- Additionality: fund money counts as additional only when federal investment in the core budget exceeds 10% of its spending (both adjusted for financial transactions, total spending also for the defence exemption).[17][4]
- Länder: €100bn shared out by fixed percentages (21.1% for North Rhine-Westphalia, 15.7% for Bavaria…), for investments of at least €50,000 approved by the end of 2036; each Land decides the municipal share, giving particular weight to financially weak municipalities. Their 0.35% borrowing margin is divided two thirds by tax revenue and one third by population.[20][21]

The debate
Citoyen takes no position: arguments are reported as their authors put them.
According to its supporters
- The CDU/CSU and SPD argue that deterrence must quickly be « credibly backed militarily » and that Germany must take on leadership in Europe; Defence Minister Boris Pistorius summed it up: « the threat situation comes before the state of the coffers ».[5]
- For the authors, the investment backlog is « palpable everywhere »: the fund secures a long-term financing basis for modernising the country and can « noticeably strengthen » medium-term growth. The Association of German Cities « very much » welcomed the bill, municipalities expecting a deficit of more than €13bn for 2024.[5][12]
- Thiess Büttner, chair of the independent advisory board of the Stability Council, found the 1% of GDP threshold « understandable » given the goal of raising security capacity quickly, and judged that raising defence spending by 1% of GDP would not overstretch the sustainability of public finances in the medium term.[11]
According to its opponents
- The FDP group chair Christian Dürr argued that the debt brake was being turned into « waste paper », starting « unrestrained debt-making », and that the unlimited defence exemption softens responsible fiscal policy; the FDP proposed instead a one-off Bundeswehr fund of up to €300bn, rejected.[5]
- The AfD, Die Linke and the BSW contested the procedure: a Bundestag already voted out was amending the Constitution days before the new one met. Die Linke denounced a « blank cheque for rearmament »; the AfD spoke of a « gigantic mortgage » on future generations. The Constitutional Court rejected their urgent applications.[5][8]
- Thiess Büttner warned that €50bn a year of extra deficits from the fund would raise the debt ratio by about 4 points by 2028, that the growth needed to offset it appears « unrealistic », and that its use must stay within EU fiscal rules — or be offset by consolidation elsewhere.[11]
- Having voted for the amendment, the Greens accused the government in September 2025 of relabelling spending as investment (« IT posts suddenly count as investment ») and warned of a « flash in the pan on credit », with a debt ratio rising above 80%.[14]
