Gilles Roth: Three percent hurdle does not have to be torn for additional military spending

Gilles Roth, Luxembourg’s Finance Minister, addressed the topic of military spending in a May 2025 interview with Luxemburger Wort, emphasizing that the “three percent hurdle” for budget deficits should not be breached to fund additional defense expenditures. This statement comes amid growing pressure on European nations, including Luxembourg, to increase military budgets in response to heightened global security concerns and U.S. demands for higher NATO contributions under President Donald Trump’s administration. Below is a detailed analysis of Roth’s position, the context of the “three percent hurdle,” and the broader implications for Luxembourg’s military spending.

Context: The Three Percent Hurdle

The “three percent hurdle” refers to the European Union’s Stability and Growth Pact (SGP) rule, which caps member states’ budget deficits at 3% of GDP to ensure fiscal discipline. Luxembourg, with a 2025 defense budget of €686 million (0.76% of GDP), faces calls to meet NATO’s 2% GDP defense spending target, a goal only 23 of 32 NATO members achieved in 2024. Roth’s statement reflects a commitment to fiscal prudence, prioritizing compliance with EU deficit limits over significantly expanding military outlays, even as global tensions—such as Russia’s invasion of Ukraine and Trump’s push for allies to spend up to 5% of GDP—intensify.

Roth’s Position

• Fiscal Responsibility: Roth argued that Luxembourg’s strong financial position, with a debt-to-GDP ratio of 27.2% (among the EU’s lowest), should not be jeopardized by exceeding the 3% deficit cap. He suggested that additional military spending could be accommodated within existing fiscal frameworks, potentially through reallocating funds or leveraging economic growth, rather than increasing borrowing.
• Defense Spending Plans: Luxembourg has increased defense spending by 67% since 2020, reaching €686 million in 2025, with plans to hit €1 billion by 2028 (1% of GDP). Projects include a military satellite (€360 million, co-funded with the U.S.) and a joint battalion with Belgium. Roth emphasized these as “targeted” investments, arguing against drastic hikes that could breach EU rules.
• Response to U.S. Pressure: Roth acknowledged Trump’s call for higher NATO contributions but noted Luxembourg’s unique constraints as a small nation with a population of 672,000 and no standing army since 1967. He advocated for “smart” spending, such as joint European defense projects, over unilateral budget increases that could destabilize public finances.

Broader European and NATO Context

• NATO Spending Trends: According to the Stockholm International Peace Research Institute (SIPRI), global military spending reached $2.4 trillion in 2023, with the U.S. leading at $916 billion (3.5% of GDP) and European NATO members increasing outlays by 16% since Russia’s 2022 invasion of Ukraine. Luxembourg’s 0.76% of GDP is among the lowest in NATO, compared to Poland (3.9%) and Germany (2% in 2024).
• Trump’s Influence: Trump’s January 2025 demand for NATO allies to spend 5% of GDP, far exceeding the 2% guideline, has strained transatlantic relations. His threats to cut U.S. NATO funding and impose tariffs on non-compliant allies, like Canada (1.37% of GDP), have pushed countries to reassess budgets. Roth’s stance aligns with Germany’s cautious approach, balancing NATO commitments with fiscal limits.
• EU Fiscal Constraints: The SGP’s 3% deficit rule, temporarily suspended during COVID-19, was reinstated in 2024, pressuring countries like France (5.5% deficit) and Italy to curb spending. Luxembourg’s 2024 budget surplus of €1.2 billion (1.5% of GDP) gives it flexibility, but Roth warned against “reckless” borrowing that could raise debt servicing costs, projected to hit 6.3% of GDP across the EU by 2054.

Critical Analysis

Roth’s position reflects Luxembourg’s dual challenge: meeting NATO expectations while maintaining its reputation as a fiscally disciplined EU member. His reluctance to breach the 3% deficit cap is pragmatic, given Luxembourg’s low debt and economic reliance on financial services, which benefit from stability. However, critics argue this underestimates the urgency of defense needs. Luxembourg’s 0.76% GDP spending, while up from 0.46% in 2020, lags behind allies like Estonia (2.73%) and risks perceptions of free-riding within NATO, especially as smaller nations face scrutiny under Trump’s “pay-to-play” rhetoric.

The claim that additional spending can fit within current budgets assumes optimistic economic growth (forecast at 2.1% for 2025) or cuts to other sectors, such as social programs, which could face domestic pushback. Studies, like one from the IMF, suggest military spending above 2% of GDP can strain developing economies but has mixed effects in advanced ones like Luxembourg, where it could stimulate technology and jobs if targeted efficiently. Roth’s focus on joint projects, like the EU’s Permanent Structured Cooperation (PESCO), is strategic but may not satisfy NATO’s demand for rapid, unilateral increases.

Public and Political Sentiment

• Luxembourg’s Perspective: X posts from Luxembourg-based users, like @Wort_LU, highlight Roth’s fiscal caution as a “sensible” response to U.S. pressure, with some praising his push for European defense collaboration. However, others, like @LuxPolitik, argue it risks Luxembourg’s NATO standing, noting that even Iceland (0% GDP) contributes via non-military support.
• European Debate: Across Europe, X sentiment is divided. Users like @EUDefence praise Germany and Luxembourg for meeting 2% targets incrementally, while @NATOwatch criticizes “laggards” for relying on U.S. protection without proportional contributions. The hashtag #NATO5Percent trended briefly, reflecting anxiety over Trump’s demands.

Conclusion

Gilles Roth’s assertion that Luxembourg can increase military spending without breaching the EU’s 3% deficit cap underscores a cautious, fiscally responsible approach amid NATO pressures. With a 2025 defense budget of €686 million (0.76% of GDP) and plans to reach 1% by 2028, Luxembourg is scaling up through targeted investments like satellites and joint battalions. However, its low spending relative to NATO’s 2% target invites criticism, especially under Trump’s aggressive stance. Roth’s strategy hinges on economic growth and EU collaboration, but risks falling short if global tensions escalate or allies demand faster progress.
