Berlin borrows €203 billion for defence

Germany is preparing to borrow €203 billion in 2027, spread across the federal budget, a defence fund and an infrastructure fund (Tagesschau, ZEIT). For a country that spent years treating public debt almost as a moral failing, the number is striking. The markets, though, are not panicking. Berlin is still borrowing at roughly 2.98% on 10-year bonds, against about 3.68% for France on the same maturity (Boursorama).

The question, then, is not whether Germany can finance the debt. It can. The harder issue is what happens when defence moves to the top of the German state’s spending list, and whether the rest of Europe can afford to follow at the same speed.

Three borrowing buckets, one shrinking middle

Germany’s constitution contains the Schuldenbremse, or debt brake, which limits ordinary federal borrowing to a narrow slice of economic output after adjusting for the cycle. Berlin has not abolished the rule. It has built a route around it. Defence spending above 1% of GDP can now sit outside the cap, while two special funds borrow separately from the main budget (ZEIT, taz).

The draft budget puts €118.7 billion of new borrowing in the core federal budget, €54.9 billion in the infrastructure fund and €30 billion in the Bundeswehr fund (ZEIT, Reuters).

Defence spending alone rises to roughly €109.8 billion. Add Ukraine aid and other security-related lines, and the total comes to about €130 billion (ZEIT). Those lines are politically protected. The pressure falls on the rest.

Finance Minister Lars Klingbeil closed a €21 billion gap through one-percent cuts across ministries, a higher tobacco tax, a new plastics levy, lower subsidies for social insurance and drawdowns from reserves built up before 2019 (Deutschlandfunk). The reserve drawdown accounts for €6.8 billion, leaving just €3.9 billion for future years (Süddeutsche Zeitung). The rainy-day money is nearly spent.

Who actually pays

The largest single budget item is the federal transfer to the pension system, at about €132 billion (Süddeutsche Zeitung). No German coalition is going to pick a fight with pensioners on this scale. So the squeeze moves elsewhere: households losing heating support, poorer countries receiving less development aid, and ministries told to make do with smaller subsidy envelopes.

Germany’s ODA, or official development assistance, is now on course to fall to 0.43% of national income by 2029 (DonorTracker). That is the money a government spends supporting poorer countries, and it is usually one of the first places to show whether a richer state’s global ambition survives contact with domestic politics.

Interest is the other bill. Federal debt-service costs are projected to rise from €41.9 billion in 2027 to €80.7 billion by 2030 (taz, Süddeutsche Zeitung). Money paid to bondholders cannot repair railways, refurbish schools or fund later tax cuts. BNP Paribas estimates German debt could reach 71% of GDP by 2030, with 10-year yields around 3.3% by late 2026 (BNP Paribas). The German state is becoming more expensive to run, and not just for one budget cycle.

The European gap this opens

Germany’s borrowing advantage over France, that 0.7-percentage-point gap in 10-year yields, matters because defence is capital-intensive. The same euro of military readiness costs Paris more than Berlin. Countries with cheaper borrowing can rearm faster. Countries with higher yields must either borrow at a steeper price, cut deeper elsewhere, or wait for EU joint financing that may not come quickly enough.

Italy has an approved EU SAFE loan line of up to €14.9 billion for defence procurement, but has not yet signed the agreement with the Commission (Quotidiano Nazionale). The Fondation Robert Schuman has warned that a defence build-up based only on national balance sheets risks splitting Europe between countries that can arm and countries that cannot (Fondation Robert Schuman).

For Ireland, with its tradition of military neutrality, the German shift lands differently than it does in Warsaw or Vilnius. But it still matters. If EU defence becomes a question of who can borrow cheaply enough to buy capacity, smaller and more fiscally constrained member states will have less say over the shape of European security, even when they are asked to live with the consequences.

On the eastern flank, the immediate test is whether German money becomes usable capability. The Bundeswehr exercised in Lithuania with 2,900 soldiers, tanks and combat helicopters (Bundeswehr). But Berlin still plans to buy some weapons from the United States, limiting the industrial gain for European supply chains (RMF24).

This budget makes German rearmament financially possible. It does not yet show whether Germany is building European defence capacity, or simply buying its own security while neighbours with dearer debt fall behind.
