Merz bets Germany's future on a borrowed century
Friedrich Merz is borrowing more than €200 billion to fund a rearmament agenda his predecessor never dared. The bill lands long after the chancellor leaves office.
On 5 July 2026, Friedrich Merz's cabinet moved closer to approving a draft budget that would unlock more than €203 billion in new borrowing — a fiscal gesture so large that it would have been unthinkable from a Christian Democratic chancellor a decade ago. The money is meant to underwrite two parallel bets: a sustained defence build-up that Merz has pledged not to "shy away" from defending, and a continuing backstop for an economy that has spent two years flirting with stagnation.
The numbers are striking, but the politics underneath are stranger still. Merz is gambling that Germans will tolerate a structural shift in how the state finances itself, and that they will accept the price tag — higher interest costs, a stretched balance sheet — in exchange for a more muscular country. The bet is not without risk, and not without precedent. It is, in fact, the closest the Federal Republic has come to a quiet rewriting of the postwar fiscal consensus since the 2008 bank rescues.
A defence-led rewrite of the debt brake
The headline figure — over €203 billion in new borrowing in a single fiscal year — is itself a relic of the looser framework the Bundestag adopted in March 2025 to exempt defence spending above one percent of GDP from the constitutional debt brake. With the federal deficit already pushed past the original ceiling by infrastructure and climate outlays, the cabinet's draft budget amounts to a second, larger expansion on top of the first. The arithmetic is no longer a marginal adjustment; it is a regime change.
The political justification has shifted accordingly. Merz's framing — that Germany has "no reason to shy away" from a higher military footprint — has migrated from campaign rhetoric into budgetary fact. Procurement timelines, ammunition stockpiles, and the Bundeswehr's chronic readiness gaps are no longer abstractions in a white paper; they are line items against which bond markets will price German sovereign risk for years to come.
A country arguing with itself
The streets outside the conference halls tell the other half of the story. On 5 July, around 20,000 demonstrators turned out against the Alternative for Germany's annual conference — a turnout that signals not the marginalisation of the right, but its continued gravitational pull on a public conversation the governing coalition is struggling to control. The protest movement against the AfD is itself large and sustained; what is striking is that it now coexists with a parallel unease about the very defence build-up Merz is funding.
In other words, the same German electorate is being asked to accept higher borrowing for the Bundeswehr while mobilising against a party that, in its softer iterations, also demands a tougher German posture abroad. The coalition arithmetic — a Merz-led CDU working with the Greens and the SPD — has held, but the public mood it sits on top of is more brittle than the finance ministry's spreadsheets imply.
The structural read
What is unfolding is a slow convergence of three pressures that European fiscal orthodoxy used to treat as separate. The first is the war on the EU's eastern border, which has turned defence procurement from a slow bureaucratic exercise into a politically urgent supply chain. The second is an industrial slowdown that has hollowed out the tax base without hollowing out welfare commitments, leaving the state with a structural deficit the previous framework could not accommodate. The third is energy transition costs that have landed earlier than billed and on a budget that was never written to absorb them.
Taken together, these pressures are pushing Germany toward a financing model closer to France's — one in which the state borrows against strategic priorities and accepts a permanently higher debt-to-GDP ratio as the cost of remaining a continental anchor. The political cost is a coalition management problem that gets harder with every additional hundred billion, because every additional hundred billion needs a story the voters will accept.
What the critics will say — and what they won't
The obvious critique is intergenerational: today's borrowing is tomorrow's taxes, and the constituency that will repay the bill has not yet voted. A second critique, more familiar in Berlin think-tanks, holds that the spending is being decided without a hard strategic audit of what the Bundeswehr actually needs — more artillery than a navy, more drones than main battle tanks, more cyber capacity than airborne platforms. A third, more uncomfortable, asks whether a country that cannot fully staff its existing forces will see any plausible return on the marginal euro.
Each of these critiques has a partial answer. Borrowing for defence is a recognised instrument across the OECD, and the geopolitical backdrop makes the strategic case unusually clear. Procurement choices can be corrected. Manpower can be addressed with conscription variants now back on the policy menu. The harder critique — that the public has not consented to this scale of fiscal expansion — is the one without a clean answer, and it is the one the next federal election will ultimately adjudicate.
What remains genuinely uncertain is the trajectory of borrowing after this budget passes. The draft is a ceiling, not a floor, and German coalition politics has a long history of letting ceilings become floors once the political mood demands more spending. Equally uncertain is whether the bond market continues to treat Bunds as the eurozone's risk-free benchmark at the current spread, or whether investors — Italian, French, or otherwise — begin to price in a slower fiscal anchor.
For now, Merz has chosen to borrow against a Germany that does not yet exist. The bet is that, by the time the bill arrives, the country will be larger, better defended, and richer — and that voters will judge the chancellor who pulled the lever accordingly. The alternative reading is that he has simply moved an unpayable invoice forward, and that the next generation of Germans will meet it on terms they did not choose.
This publication framed the borrowing question as a structural shift rather than a one-year fiscal event, and read the AfD protest numbers as a parallel signal of political strain rather than a counter-narrative to the defence build-up.
