Germany Breaks Its Debt Brake as NATO Defense Spending Hits Record $574 Billion
European allies reached a combined $574 billion in defense spending in 2025, with Germany's constitutional constraint shattered and US contractors racing to capture a market analysts value at $1.14 trillion by 2035.
Germany abandoned a constitutional constraint that had capped federal borrowing for more than a decade, unlocking $114 billion for defense investment in 2025. The move came as NATO's European members and Canada collectively raised military spending by 20 percent in real terms to a combined $574 billion — the largest single-year increase in the alliance's history, according to data cited in Foreign Policy.5
The surge marks a structural break from a decade of European defence underfunding that followed the 2014 Wales summit, when allies pledged to reach 2 percent of GDP. That target went largely unmet for years. Now the arithmetic has shifted: the 2 percent threshold is becoming a floor rather than a ceiling, with Eastern European nations pushing further.2
Poland illustrates the shift most sharply. Warsaw may spend close to 4 percent of GDP on defence in 2026, according to projections cited by The Economist. Its purchases from US contractors include $4.7 billion for helicopters, $4.6 billion for F-35 fighter jets, and an estimated $10 billion in HIMARS rocket launch systems. Beyond hardware, Poland has signed a deal worth more than $25 billion with a consortium of American companies to build a nuclear power plant — a transaction that blurs the line between defence patronage and energy policy.4,2
US defense firms are not waiting to see whether European spending holds. They are positioning in a market that analysts say could be worth roughly $1.14 trillion by 2035, with the broader trans-Atlantic commercial relationship — $7.4 trillion in cross-border investment and roughly $2 trillion in annual trade — showing no sign of contraction despite sweeping US tariff increases in 2025.5
Germany's fiscal decision carries particular weight. For years, the debt brake served as the binding constraint on Berlin's public investment, limiting its ability to spend on both military capability and energy infrastructure. Breaking it to fund defence — rather than to accelerate the energy transition — reflects a political judgement about which security threats are most immediate. Germany's defence strategy, as reviewed by War on the Rocks, aims to build the strongest land force in Europe while deploying that capability only in collective European interests.3
The timing is not coincidental. Russia's natural gas exports to EU member states have fallen by more than two-thirds since 2020, from 14.7 billion cubic feet per day to a fraction of that, as European sanctions and market forces redirected supply chains. The energy dependency that once constrained European foreign policy no longer exists in the same form. The severing of those ties changed the political calculus for countries that had long balanced security and commercial relationships with Moscow.1
Whether the spending surge translates into actual capability is a different question. A German NATO commander, speaking to The Economist, put the institutional problem plainly: "We are champions in announcing things, not in implementing." At the Wales summit in 2014, allies made commitments that took years to fund and longer still to field.2
Several NATO members are already testing whether political will matches fiscal room. Canada, one of the largest economies in the alliance, has consistently spent below the 2 percent threshold and is widely seen as the hardest case for sustained increases. Ben Wallace, Britain's former defence secretary, has warned of backsliding among members who reach 2 percent briefly before easing back.2
The $114 billion Germany committed in 2025 is a statement of intent. How quickly those funds flow into procurement contracts, training, and operational readiness will determine whether the trans-Atlantic renegotiation produces a more capable European defence posture — or simply a larger line item on European balance sheets for US contractors to capture.
