Merz's €203bn borrowing spree signals Germany's final turn away from austerity

Friedrich Merz has stopped apologising for German rearmament. On 4 July 2026 the chancellor publicly declared that Germany has "no reason to shy away" from defending a military-spending drive that, until two years ago, would have been politically unthinkable in Berlin. A day later, on 5 July 2026, his cabinet moved to back the rhetoric with cash: a draft budget that reportedly commits more than €203 billion in new borrowing.

That is not a budget cycle. It is a regime change inside the Bundeshaushalt. For the first time since the constitutional debt brake was tightened in 2009, the German state is preparing to borrow at a scale designed to fund a strategic pivot rather than a cyclical response to recession. The era of austerity as identity politics in Berlin is over.

What Merz is actually breaking

The Schuldenbremse — the constitutional limit that caps the federal structural deficit at roughly 0.35% of GDP — was the central ideological artefact of Germany's post-2009 fiscal compact. It was the price Berlin exacted from southern Europe during the eurozone crisis: fiscal discipline as the price of monetary union. It was also, more quietly, the instrument that kept German public investment running below depreciation in key areas — rail, hospitals, digital infrastructure, defence procurement.

Merz's €203 billion draft does not abolish the debt brake. It routes around it. The carve-outs — defence spending above 1% of NATO GDP, and a wider "security and resilience" envelope — are not new, but the scale is. Reports point to the second largest defence budget in the Bundeswehr's history, part of a broader push that has seen Berlin commit to NATO's 5% target by the middle of the decade. Borrowing to fund armaments is no longer treated as profligacy. It is treated as statecraft.

The cover story — and what is wrong with it

The official framing presents this as a Russia-driven emergency response. The full-scale invasion of Ukraine made German rearmament unavoidable, the argument runs; only the wilfully naïve still question the need for ammunition stockpiles and air defence.

The counterpoint is more interesting. Germany's defence gap has been open for at least two decades. It was visible in the 2022 Ringtausch swap deal with the Netherlands, in the empty munitions depots documented by the Bundeswehr's own reports, in the slow collapse of the Bundeswehr's operational readiness through the 2010s. Merz's accelerated schedule — and his willingness to drop the fiscal fetters — reflects a calculation that arrived in Berlin before Moscow's 2022 invasion fully transformed European threat perception: that a major EU economy on NATO's eastern flank cannot indefinitely run its defence ministry as a budgetary footnote.

What has changed is not the threat. It is Germany's willingness to pay for a credible answer.

The structural frame

Two things are happening at once, and the second is more important than the first. The first is straightforward defence catch-up. The second is the end of the austerity doctrine that has constrained European public investment since 2010.

That doctrine exacted a high price from the European periphery — Greece, Portugal, Spain, Italy — and from European public goods alike. It was always an awkward fit for a continent that allowed monetary union without fiscal union, and that relied on German demand as the implicit external balancer of the eurozone. Germany's own infrastructure — the autobahn, the rail network, the hospital estate — accumulated deferred maintenance that is now showing up in service quality and industrial competitiveness. The trade surplus that funded the surpluses of the rest of the bloc is being reassessed in Berlin and Brussels at the same time. A €203 billion draft budget, with a defence-orientation, is not a one-off. It is the first line of a new budget grammar that treats German public borrowing as a normal instrument of strategic policy, not as a sin.

The counter-narrative

The fiscally conservative critique has not disappeared. It lives on inside the CDU's own Bavarian sister party, inside the Bundesbank's regular reports, and inside the FDP's lingering insistence on a debt-brake-as-identity. The objection is the conventional one: that normalising €200bn-class borrowing will, over a five-to-ten-year horizon, push German debt-to-GDP above the 90% mark, harden the Bund's debt-service bill against future interest normalisation, and re-impose the very constraints that Berlin spent fifteen years escaping from the eurozone's periphery.

It is a serious objection. It does not, however, hold the same political weight it held in 2015. The reason is that the costs of under-investment — strategic, infrastructural, demographic — are now on the same ledger as the costs of new borrowing, and the strategic column reads larger. The Bundesbank can object; the Bundestag's coalition arithmetic no longer lets that objection set the ceiling.

Stakes

Berlin is moving from price-taker to price-maker inside European fiscal politics. If €203 billion survives the Bundestag vote and the constitutional challenge that is already being drafted, several things follow.

Inside Germany, the political ceiling on defence and infrastructure spending is gone; the binding constraint is delivery, not authorisation. Inside the eurozone, Berlin is implicitly admitting what it denied through the 2010s: that the bloc's investment needs exceed the savings rate of its largest creditor. Inside NATO, Germany becomes a backstop contributor rather than a free-rider, with corresponding expectations on force posture. And inside Brussels, the next framework on EU fiscal rules — long stalled — now has a different reference member state than it had a year ago.

The road that ends at this budget started somewhere around 2014. It took a war to make it walkable. That does not make the destination wrong. It does, however, mean the destination was chosen later than it should have been, with costs that began accruing long before the cabinet draft.
