Germany Defense Spending

---

SITUATIONAL SUMMARY

Approximately 10 months ago — in late winter and spring of 2025 — Germany underwent what many analysts described as the most consequential shift in its defense and fiscal policy since reunification. The events unfolded rapidly across several interconnected fronts.

The Political Trigger

Germany's coalition government under Chancellor Olaf Scholz collapsed in late 2024, triggering snap elections held on February 23, 2025. Friedrich Merz's center-right CDU/CSU conservatives won, and Merz moved quickly to form a coalition with the center-left Social Democrats (SPD). The election occurred against a backdrop of two consecutive years of economic contraction (-0.9% in 2023, -0.5% in 2024), rising security anxieties following Russia's continued war in Ukraine, and a dramatically changed transatlantic relationship under the returning Trump administration.

The Debt Brake Reform — Germany's Fiscal Rubicon

The single most structurally significant development was the agreement, announced March 4-5, 2025, to reform Germany's constitutionally enshrined "debt brake" (*Schuldenbremse*). This rule, embedded in Germany's Basic Law since 2009, limits new government borrowing to just 0.35% of GDP annually — one of the most restrictive fiscal constraints of any major economy in the world. Merz and the SPD agreed to exempt defense spending above 1% of GDP from this constraint entirely, and to create a separate €500 billion ($533-591 billion) off-budget infrastructure fund for transport, digital, and energy investment over ten years.

Critically, the coalition rushed this constitutional amendment through the *outgoing* parliament before the new Bundestag was seated — a deliberate maneuver because the incoming parliament would include larger blocs of the far-right Alternative für Deutschland (AfD) and far-left parties, which together would have held a blocking minority sufficient to prevent the two-thirds majority required for constitutional change. Berenberg economist Holger Schmieding called it "a really big bazooka" and "a fiscal sea change for Germany."

The Defense Spending Numbers

The scale of the commitment is historically unprecedented for postwar Germany. By June 2025, the new government had approved a five-year defense spending plan totaling €649 billion ($761 billion), with annual allocations rising from €86 billion (2.4% of GDP) in 2025 to €162 billion by 2029 — explicitly targeting NATO's newly elevated 3.5% GDP spending benchmark (with an additional 1.5% for broader security matters, reaching the 5% figure backed by Trump). Germany's Foreign Minister Johann Wadephul publicly endorsed the 5% framework at a NATO foreign ministers meeting in Turkey in May 2025.

The financing mechanism involves €400 billion in new borrowing over five years — a dramatic departure from Germany's postwar fiscal conservatism. Net government borrowing jumped to €81.8 billion in 2025 alone, up from €33.3 billion the prior year. The existing €100 billion special military fund created by Scholz after Russia's 2022 invasion was expected to be depleted by 2027.

Chancellor Merz framed the spending explicitly in terms of European sovereignty rather than American appeasement: "Not to do the United States a favor — but because Russia actively threatens the freedom of the entire Euro-Atlantic area."

The Execution Gap

Even as the political commitments were made, Goldman Sachs analyst Niklas Garnadt warned in February 2026 that actual defense spending execution would fall short of the ambitious budget targets in the near term. While Germany's defense budget surged by 25 billion euros to 119 billion euros on paper, Goldman estimated actual spend would reach approximately 109 billion euros (2.4% of GDP) — still a substantial 21 billion euro increase over the prior year, but below headline targets. The constraint is not political will but industrial and bureaucratic capacity: procurement pipelines, contracting processes, and manufacturing capacity cannot be scaled overnight.

The Broader Strategic Context

Germany's shift occurred within a wider European rearmament movement. NATO's 32 members were on track to collectively meet the 2% GDP target for the first time by end-2025, though only three nations had met the new 3.5% target. Germany and the UK's defense chiefs published a joint op-ed in February 2026 warning that "Moscow's intentions range wider than the current conflict" and calling for a "whole-of-society approach" to defense — acknowledging that public opinion in both countries remained skeptical, with only 24% of Germans favoring increased defense spending if it meant cuts to other programs.

Economic Context

Germany's economy returned to modest growth of 0.2% in 2025 after two years of contraction, driven by consumer and government spending even as exports sagged under US tariffs and Chinese competition. A group of leading economists projected 0.9% growth for 2026, contingent on the fiscal stimulus flowing through at the expected pace. Bank of America data from early 2026 showed a 40% surge in German factory orders on a three-month annualized basis, including heavy machinery and defense-related equipment — early evidence the spending was beginning to materialize in the real economy.

Points of Tension

Internal coalition friction was visible from the start. Left-leaning SPD members called percentage-based military targets "irrational," while the Greens accused the government of budget "tricks." Public opinion remained divided, with polls showing roughly half of Germans supporting the debt brake reform but only a quarter willing to accept cuts to social programs to fund defense. The Washington Examiner (a conservative American outlet) framed Germany's prior spending as "outrageous" inadequacy, reflecting longstanding American frustration — a notably more critical framing than German domestic coverage, which emphasized the historic nature of the shift.

SINCE THEN

Between approximately May 2025 and March 2026, the following developments occurred or can be assessed:

What Was Implemented

The constitutional debt brake reform was successfully passed through the outgoing Bundestag in March 2025, clearing the two-thirds threshold before the new parliament seated. This was the critical legal foundation for everything that followed. The Merz-SPD coalition was formally established and the five-year €649 billion defense plan was approved by June 2025. Germany's defense budget for 2025 was set at €86 billion (2.4% of GDP), with Ukraine aid bringing the effective total to €95 billion. NATO confirmed by late August 2025 that its members were collectively on track to meet the 2% GDP target for the first time.

What Remains Incomplete

The Goldman Sachs execution warning has proven prescient. As of early 2026, actual defense spending is running below the headline budget allocation — Goldman estimated a roughly 10 billion euro shortfall between the budgeted 119 billion euros and the likely actual spend of 109 billion euros. The gap reflects structural bottlenecks: Germany's defense procurement bureaucracy, the Bundeswehr's historically underdeveloped contracting infrastructure, and European defense industry capacity constraints. Rheinmetall and other manufacturers are ramping up, but production timelines for major systems (artillery, armored vehicles, air defense) extend years into the future.

The Bundeswehr's readiness problems — described in a 2022 parliamentary commissioner report as having roughly half its equipment non-operational — cannot be resolved by budget allocations alone. Training pipelines, personnel shortfalls, and maintenance backlogs persist.

Public opinion remains a structural constraint. The joint German-UK defense chiefs op-ed in February 2026 was itself an acknowledgment that the "whole-of-society" buy-in needed to sustain multi-decade rearmament has not been achieved. With only 24% of Germans willing to accept social program cuts for defense, any future economic downturn could generate significant political pressure to slow the spending trajectory.

Changed Conditions

The geopolitical environment has, if anything, intensified the urgency. The Trump administration's posture toward NATO and Ukraine remained transactional and uncertain through 2025-2026, reinforcing European calculations that US security guarantees cannot be assumed. Russia's continued offensive operations in Ukraine, combined with Moscow's broader signaling about Western Europe, have kept threat perceptions elevated. Germany's decision to allocate €9 billion annually for Ukraine aid — cementing its role as Kyiv's leading European backer in the absence of reliable US support — represents a significant strategic commitment with long-term fiscal implications.

HISTORICAL PARALLELS

Parallel 1: West Germany's Rearmament and the Bundeswehr's Creation (1950-1956)

Following World War II, West Germany was prohibited from maintaining any military forces under the terms of its occupation. The outbreak of the Korean War in 1950 and the perceived Soviet threat to Western Europe prompted a dramatic reversal: within six years, West Germany had rearmed, created the Bundeswehr, and joined NATO (1955). Chancellor Konrad Adenauer navigated intense domestic opposition — many Germans, haunted by the Nazi Wehrmacht, were deeply hostile to any German military — while simultaneously using rearmament as leverage to accelerate West Germany's sovereignty and integration into Western institutions.

The parallel to today is striking. Then as now, an external security shock (Korea/Soviet threat vs. Ukraine/Russian aggression) overcame deep German domestic resistance to military spending. Then as now, the political window for action was narrow and required decisive maneuvering — Adenauer had to overcome opposition from his own public and from France; Merz had to rush constitutional changes through an outgoing parliament. Then as now, the stated goal was European security architecture rather than purely national interest.

The resolution of the 1950s parallel is instructive: West Germany did successfully rearm, but the process took longer than anticipated, faced persistent capability gaps, and required sustained political management over decades. The Bundeswehr that emerged was a capable force, but it took until the 1970s-80s to reach its full Cold War strength. This suggests Germany's current trajectory is sustainable but should be measured in decades, not years.

Where the parallel breaks down: Today's Germany is rearming within an existing NATO framework with established procurement relationships, rather than building from zero. The fiscal tools available (bond markets, EU frameworks) are more sophisticated. But the cultural resistance may be comparably deep.

Parallel 2: Japan's Post-2022 Defense Spending Shift Under Kishida and Takaichi

Japan's trajectory offers a more recent and structurally analogous case. For decades, Japan maintained a self-imposed cap of approximately 1% of GDP on defense spending — a norm rooted in post-WWII pacifist constitutional interpretation, much as Germany's debt brake reflected postwar fiscal conservatism. In December 2022, Prime Minister Kishida announced Japan would double defense spending to 2% of GDP over five years, financed partly by tax increases and debt — a decision that required overcoming deep public skepticism and coalition friction. By 2026, PM Takaichi has gone further, formally breaking with fiscal austerity as a core policy pillar.

The structural similarities to Germany are direct: both are major postwar democracies with constitutionally or normatively embedded constraints on military spending; both faced a specific geopolitical shock (China/North Korea for Japan, Russia/Ukraine for Germany) that created political space for historic reversals; both face the challenge of translating budget commitments into actual capability within defense industries that had atrophied under decades of underinvestment.

Japan's experience highlights the execution challenge Germany now faces. Japanese defense procurement has been chronically slow — the country's defense industry, while technologically sophisticated, lacks the surge capacity to absorb rapid budget increases efficiently. Early reports from Japan's rearmament effort showed significant underspending relative to allocations in the first two years, closely mirroring Goldman Sachs's warning about Germany. The lesson: announcing historic spending commitments is the easy part; building the institutional and industrial infrastructure to spend money effectively on defense takes years longer than the political announcements suggest.

SCENARIO ANALYSIS

MOST LIKELY: Sustained But Uneven Ramp-Up — Capability Lags Commitments by 3-5 Years

Germany's defense spending trajectory is now legally locked in through the constitutional debt brake reform and politically sustained by a durable CDU/CSU-SPD coalition with strong incentives to maintain the course. The fiscal architecture — the €500 billion infrastructure fund, the defense exemption from borrowing limits, the five-year €649 billion plan — is real and binding in ways that Scholz's 2022 Zeitenwende promises were not. Factory order data and Rheinmetall's production ramp-up confirm the spending is beginning to flow into the real economy.

However, the Goldman Sachs execution gap will persist and likely widen before it narrows. Germany's defense procurement bureaucracy, the Bundeswehr's institutional inertia, and European defense industry bottlenecks (particularly in artillery ammunition, armored vehicles, and air defense systems) mean that actual military capability will lag budget commitments by three to five years. The 2.4% of GDP actually spent in 2025-2026 will gradually close toward the 3.5% target by 2028-2029, but the Bundeswehr Merz envisions as "the strongest conventional army in Europe" will not exist in that form until the early 2030s at the earliest.

Public opinion remains the key political vulnerability. With only 24% of Germans willing to accept social program cuts for defense, any significant economic downturn — particularly if US tariffs deepen or the Ukraine war produces a settlement that reduces perceived threat levels — could generate coalition pressure to slow the trajectory. The SPD's left flank, already vocal about "irrational" percentage targets, would be the most likely vector for such pressure.

KEY CLAIM: Germany will meet its 3.5% GDP defense spending target by 2029 on paper, but actual Bundeswehr operational readiness will remain significantly below stated capability goals through at least 2031, with procurement execution running 15-20% below annual budget allocations.

FORECAST HORIZON: Long-term (1-3 years)

KEY INDICATORS:

1. Annual Bundeswehr readiness reports showing the percentage of major equipment systems operational — if this figure fails to rise above 60% by end-2026 (from the roughly 50% baseline described in 2022 parliamentary reports), it signals the execution gap is structural rather than transitional.

2. SPD internal party votes or public statements from SPD Bundestag members explicitly calling for defense spending reductions or caps — this would signal the coalition's political sustainability on this issue is eroding ahead of the next federal election cycle.

WILDCARD: A Ukraine Settlement Triggers European Security Fragmentation and German Retrenchment

The entire architecture of Germany's rearmament rests on a sustained, shared threat perception anchored in Russia's war in Ukraine. If the Trump administration brokers a ceasefire or settlement in Ukraine — particularly one that leaves Russia in control of significant Ukrainian territory and is framed by Washington as a "success" — the political calculus in Germany could shift rapidly. A settlement, even an imperfect one, would reduce the immediate visceral urgency that drove the March 2025 constitutional reforms through parliament in days rather than months.

In this scenario, the SPD's left flank and the broader German public (74% of whom were already skeptical of defense spending increases at the expense of social programs) would have political cover to demand a "peace dividend" — slowing the spending ramp-up, redirecting infrastructure funds toward social priorities, and questioning whether the full €649 billion commitment remains necessary. The AfD, which has consistently opposed NATO spending targets and expressed sympathy for Russian positions, would amplify this pressure from the right. The coalition could fracture or be forced to renegotiate its defense commitments.

This scenario would have consequences far beyond Germany: it would undermine the broader European rearmament momentum, call into question NATO's new 3.5% target, and potentially leave Eastern European members — Poland, the Baltic states — strategically exposed if both US and German commitments soften simultaneously.

KEY CLAIM: If a US-brokered Ukraine ceasefire is announced before the end of 2026, Germany's actual defense spending growth rate will slow by at least 20% relative to the five-year plan within 18 months of the announcement, as coalition politics shift toward social spending priorities.

FORECAST HORIZON: Medium-term (3-12 months) for the trigger; long-term (1-3 years) for the full retrenchment dynamic to play out.

KEY INDICATORS:

1. A formal US-Russia-Ukraine ceasefire announcement or framework agreement — this is the primary trigger event that would activate the political dynamics described.

2. German opinion polling showing a shift in public support for defense spending below 40% approval (from the current ~49% who support the debt brake reform) — this would signal the political foundation for sustained rearmament is eroding.

KEY TAKEAWAY

Germany's defense transformation is real, legally entrenched, and historically significant — but the gap between budgetary commitment and actual military capability is the defining story that most single-source coverage misses. The constitutional debt brake reform and the €649 billion five-year plan represent a genuine structural break from postwar German fiscal and strategic norms, comparable in significance to the 1955 rearmament; yet Goldman Sachs's execution warning, the Bundeswehr's documented readiness deficits, and the persistent public skepticism (only 24% of Germans support defense increases at the cost of social programs) collectively suggest that the Bundeswehr Merz envisions will not exist in operational form for at least a decade. The most important variable is not whether Germany will spend the money — the legal architecture makes reversal difficult — but whether European threat perceptions remain elevated long enough for the industrial and institutional infrastructure to catch up with the political ambition.
