The Story

Why Now

On 16 September 2025, the European Commission endorsed Germany's medium-term fiscal-structural plan (MTFSP). The endorsement came five months after Germany amended its constitution to allow unlimited debt financing for defence spending above 1% of GDP and created a €500 billion (11% of annual GDP) extrabudgetary infrastructure fund. The Commission's approval was supposed to close the book on a contentious process. Instead, Bruegel's analysis published on 20 May 2026 shows the endorsement rests on assumptions so optimistic that Germany's debt — already at 66% of GDP — will likely continue rising past the end of the seven-year adjustment period.

The timing matters because the EU's reformed fiscal rules, adopted in 2024, are facing their first real test. Poland has already demanded an "escape clause" to exempt its defence spending from the 3% deficit ceiling, citing the same geopolitical logic that drove Germany's constitutional reform. France, Italy and other high-debt states are watching closely. If Germany — the EU's benchmark for fiscal discipline — can get away with backloaded adjustments and inflated growth assumptions, the entire framework loses credibility before it has been fully implemented.

The Actors

Germany's coalition government (CDU/SPD): Chancellor Friedrich Merz needs to deliver on rearmament promises while keeping the SPD onside after two state election defeats severely weakened the junior partner. The MTFSP is a political compromise: it allows higher spending now in exchange for a sharp fiscal brake after 2026. Bruegel's Zettelmeyer calls this adjustment "not credible" — the required cuts to non-defence spending would amount to roughly 2% of GDP between 2028 and 2031, a scale of retrenchment Germany has never delivered in peacetime.

The European Commission: By endorsing Germany's plan and its "national escape clause" application — which allows spending up to 1.5% of GDP above the baseline path — the Commission set a precedent. Finland was the only other country to receive a comparable deviation, and only for very specific reasons. For Germany, the Commission accepted assumptions about nominal GDP growth that Bruegel's stress-testing shows are 0.5–1.0 percentage points too high. The Commission's leniency is not accidental. It reflects a political reality: with war in Ukraine and Trump threatening 25% tariffs on EU autos (announced 1 May 2026), nobody in Brussels wants to pick a fight with Berlin over spreadsheet assumptions.

Poland: Defence minister Andrzej Domański has been the most vocal critic of the fiscal rules, with defence spending nearly doubling from 2.5% of GDP in 2022 to almost 5% in 2025. Poland is already subject to an excessive deficit procedure (EDP) for running a 5.7% fiscal gap. Domański's push for a "golden rule" — exempting military investment from debt calculations — has been rejected by Bruegel and other economists on sustainability grounds. But if Germany's plan effectively achieves the same outcome through creative accounting, Poland will demand equal treatment.

The Stakes

The stakes are institutional, not just fiscal. The EU's reformed Stability and Growth Pact was designed to replace the arbitrary enforcement of the 2010s with a rules-based debt sustainability analysis (DSA). Germany's MTFSP exposes a flaw: the DSA is only as credible as the growth assumptions plugged into it. If low-risk countries can assume away their debt trajectories, high-risk countries will follow. As Bruegel's Zettelmeyer and Welslau write: "The Commission's approval of the German plan establishes a precedent that could undermine the credibility of the EU's fiscal framework."

The economic stakes are also significant. Germany's planned expenditure deceleration after 2026 — if it happens — will be deeply contractionary. Bruegel estimates the required non-defence cuts at 2% of GDP over three years. That is larger than the 2010–2012 austerity that helped push the Eurozone into a double-dip recession. If Germany instead ignores the EU rules and lets debt drift higher, it risks a collision with the Commission that could trigger financial market volatility.

The Context

Background

The current tension traces back to March 2025, when Germany amended its constitutional "debt brake" to exempt defence spending above 1% of GDP from borrowing limits. The change was a response to Russia's full-scale invasion of Ukraine and Trump's increasingly hostile trade posture. The amendment also created a €500 billion infrastructure fund, financed over twelve years, for transport, digital and energy investment.

The constitutional reform was hailed as a "game changer" for European rearmament. But it created a direct conflict with EU fiscal rules, which require Germany to put its debt-to-GDP ratio — currently above 60% — on a declining trajectory over the medium term. The MTFSP was Berlin's attempt to square this circle: it projects an initial widening of the structural primary balance (from -0.9% in 2024 to -1.8% in 2026) followed by a sharp reversal to +1.1% by 2031.

The problem is arithmetic. Under the plan's own assumptions, Germany's debt starts falling before 2031. Under Bruegel's more realistic nominal growth assumptions, it does not.

The Bigger Picture

This is not just a German story. The EU is undergoing what Bruegel calls a "defence transition" — a structural shift from post-Cold War disinvestment to peacetime rearmament unprecedented in scale. The IMF, in its April 2026 World Economic Outlook, warned that defence spending creates macroeconomic trade-offs: it boosts growth short-term but crowds out other investment and, under rigid fiscal rules, forces painful adjustment elsewhere.

The bigger question is whether the EU's fiscal framework can survive the defence transition without reform. Bruegel proposes two options: first, allow low-risk countries with credible investment plans longer than the current seven-year maximum adjustment period; second, raise the Treaty's debt reference value from 60% to 90% of GDP. Neither requires treaty change immediately, but both face political resistance from fiscal hawks in the Netherlands, Austria and the Nordic states.

The transatlantic dimension adds urgency. Trump's 25% auto tariff announcement on 1 May 2026 hit German exports directly. Merz's government faces simultaneous pressure to spend more on defence, absorb trade shocks, and comply with fiscal rules that were designed for a different era. Something has to give.

The Data

Market Impact

German bund yields retreated from their 15-year peak of 3.20% (mid-May) to 3.06% by 22 May, partly on signs of easing Hormuz tensions. But the fiscal story is keeping term premia elevated. Investors are pricing in two risks: first, that Germany will not deliver the promised post-2026 consolidation, leading to higher supply; second, that the EU fiscal framework will be progressively eroded as more countries seek exemptions.

The ECB's June 11 rate decision is the next major event. Markets price an 85% probability of a hike to 2.25% (ECB-Watch.eu, 24 May). If Lagarde follows through, the euro could strengthen against the dollar — but the fiscal divergence between Germany's loose stance and the ECB's tightening creates a policy mix that historically weakens the currency.

What's Priced In

Futures markets show limited conviction on German fiscal policy. The bund curve is steepening, suggesting investors expect either higher issuance or higher rates, but not both simultaneously. The 2s10s spread widened to +85bp, the steepest since February 2026. This is consistent with a "no default, no discipline" equilibrium: markets trust Germany will never default, but no longer believe it will strictly follow EU rules.

Scenarios

Base Case (60% probability): Germany implements its MTFSP superficially — meeting the letter of the rules while missing the debt trajectory target. The Commission issues mild warnings but no penalties, citing geopolitical exigencies. Poland receives a similar leniency on its EDP. EU fiscal rules are gradually hollowed out but not formally amended.

Upside Case (25% probability): The Commission revises its assessment after Bruegel's critique gains traction in the European Parliament. Germany agrees to a technical adjustment extending the adjustment timeline to ten years for low-risk countries with credible investment plans. Poland's deficit is brought into compliance by 2028 through a combination of growth and modest cuts. The fiscal framework gains credibility.

Downside Case (15% probability): A coalition crisis in Berlin — triggered by SPD resistance to welfare cuts — forces early elections. A new government abandons the MTFSP commitment entirely, letting debt rise unchecked. The Commission, paralysed by political divisions, fails to act. Market spreads on Italian and French debt widen as investors price in moral hazard.

The Trigger

The specific event that would flip the probabilities: a downgrades of Germany's sovereign credit outlook by S&P or Moody's citing fiscal slippage. Germany has held a stable AAA/AAA rating since reunification. Even an outlook revision to "negative" would shock European bond markets and force Berlin to choose between rearmament and credibility.

The Question

If the EU's fiscal rules cannot accommodate Germany's defence transition without breaking, does the framework survive at all — or does it get replaced by ad hoc national exemptions until the next crisis forces a complete rewrite?

Watch For

• German coalition negotiations on welfare reform by 15 June 2026 — SPD resistance could collapse the MTFSP consensus • European Commission mid-term review of Germany's plan, expected July 2026 — first formal test of the DSA's credibility • ECB Governing Council decision, 11 June 2026 — rate hike to 2.25% would tighten financial conditions just as Germany needs fiscal space • Polish EDP ruling by the Council, expected Q3 2026 — if Poland gets leniency, the precedent is set for all high-defence states
