Berlin’s Debt Fills Budget Gaps

Germany’s cabinet has approved €838 billion in new borrowing between 2027 and 2030, divided between defence, infrastructure and climate spending (BMF, DW). For Malta, the point is not only that Europe’s largest economy is borrowing heavily. It is that Berlin is doing so while keeping the legal appearance of fiscal discipline, the same discipline it has often expected smaller member states to respect.

The real question is what this debt buys. If it produces new railways, electricity grids and defence capacity, Germany’s shift may strengthen the European economy around it. If it mainly allows old spending to be moved into less visible accounts, then the headline figure is less a national investment plan than an accounting manoeuvre. The early numbers make the second reading difficult to dismiss.

Most of the Money Isn't New

The key word is additionality. In plain terms: does a borrowed euro pay for something that would not otherwise have happened, or does it replace money the government would have spent from ordinary revenue anyway?

The ifo Institute tested this against 2025 data, the first year Germany’s infrastructure special fund was active. Berlin borrowed €24.3 billion through the fund. Actual federal investment rose by only €1.3 billion compared with 2024. ifo’s conclusion was blunt: 95% of the new debt did not become additional investment. The IW Cologne institute calculated 86% displacement. On either estimate, most of the “infrastructure” borrowing was filling gaps in the normal budget.

Finance ministry economist Armin Steinbach argued that the spending was still additional because it would not have taken place under tighter financial conditions. That may be politically true, but it cannot be verified from the accounts. What the accounts show is borrowing rising much faster than measured investment.

How the Debt Brake Stays Intact on Paper

Germany’s debt brake, the constitutional rule that limits structural borrowing to 0.35% of GDP, remains in place. But Berlin is moving most of the new spending around it through two routes.

The first is defence. Spending on defence and security above a set threshold is exempt from the cap entirely. In 2027, that exemption covers €85.4 billion of the core budget’s €118.7 billion in new debt. The brake still applies, but not where the biggest increase is happening.

The second route is the Sondervermögen, special off-budget funds with their own borrowing powers. The debt does not sit inside the annual budgets of individual ministries, but it still ends up on the public balance sheet. Taken together, Germany will borrow more than €200 billion in 2027 alone (BMF, Reuters via Marketscreener). At the same time, every non-defence ministry faces a 1% spending cut. The transport budget falls from €27.9 billion to €26.4 billion (vergabeblog.de).

The Eurobond Contradiction

Germany can borrow on this scale because its debt-to-GDP ratio is around 62.5% (Eurostat). Italy, at 135.3% and under an excessive-deficit procedure, has no comparable room. That procedure is the EU’s formal process for governments that breach deficit or debt rules.

This is where Berlin’s European position becomes harder to defend. Germany is borrowing at record scale nationally while still blocking eurobonds, the common EU debt instruments that would give other member states wider fiscal space. Italy and Spain are now jointly pushing for shared European debt. For a small eurozone state like Malta, the issue is familiar: EU rules often look neutral until one asks which countries have the balance sheets to work around them.

Delivery Is the Binding Constraint

German taxpayers will carry higher interest costs. Planned debt service rises from €33.6 billion in 2026 to €82.1 billion by 2030 (Surplus Magazin). Scope Ratings estimates that the programme could add 0.3–0.4 percentage points to annual growth, but only if the projects are actually built. Bruegel warns that larger defence budgets, without coordinated procurement, will not automatically create efficient production lines.

The main constraint is not the availability of money. 36% of the 2025 modernisation budget went unspent because planning capacity and procurement systems could not move fast enough. The test for the €838 billion is not whether Berlin can borrow it. It is whether Germans, and the rest of Europe, see the result in working railways, stronger grids and usable military capacity. Budget arithmetic alone does not deliver any of that.
