Global Defense Spending Hits Record $2.7 Trillion: The New Arms Race in Data

In 2024, the world spent $2.72 trillion on its militaries. That figure, from SIPRI's latest yearbook, represents a 9.4% real-terms increase over 2023 — the steepest single-year rise since at least the end of the Cold War. The International Institute for Strategic Studies projects spending will surpass $2.6 trillion again in 2026, and the trajectory shows no sign of flattening. Something fundamental has shifted in the global security order, and the budget numbers tell the story more clearly than any diplomatic communiqué.

The Top 10: Where the Money Goes

The concentration of military spending at the top remains striking. The five largest spenders — the United States, China, Russia, Germany, and India — together account for 60% of the global total, spending a combined $1.64 trillion.

The United States alone accounts for 36.7% of global military spending — more than the next nine countries combined. At $997 billion, American defense expenditure in 2024 approached the psychologically significant $1 trillion mark, a threshold it is widely expected to cross in the current fiscal year. But the more revealing story is further down the list, where the fastest growth is occurring.

Europe's Awakening: From 2% to 5%

For three decades after the Cold War, European defense budgets followed a predictable downward glide path. The so-called “peace dividend” allowed governments to redirect military spending toward healthcare, pensions, and infrastructure. Russia's full-scale invasion of Ukraine in February 2022 ended that era. The data since has been remarkable.

Germany's defense budget has effectively doubled in four years — from roughly €47 billion in 2021 to €95 billion in 2025, an increase of 23% in real terms in 2024 alone. That trajectory elevated Germany from seventh to fourth in the global rankings, leapfrogging the United Kingdom, Saudi Arabia, and France. Berlin's €100 billion special fund (Sondervermögen) for the Bundeswehr, created in June 2022, accelerated procurement, but the longer-term significance lies in the structural shift: Germany now aims for €152 billion by 2029, or roughly 3.2% of GDP, which would have been unthinkable a decade ago.

France allocated €68.5 billion for defense in 2026 (2.25% of GDP), a figure that represents steady increases despite fiscal consolidation pressures. Poland, however, stands out as the most aggressive spender proportionally: at 4.7% of GDP in 2025, Warsaw's defense budget exceeds NATO's old 2% guideline by a factor of more than two. Poland's proximity to Russia and Belarus, combined with its role as a logistics hub for Ukrainian defense, partly explains this. So does a broader political consensus in Warsaw that conventional deterrence is the country's best insurance policy.

At the 2025 Hague Summit, NATO allies committed to a new headline target: 5% of GDP on defense and security-related spending by 2035, with at least 3.5% earmarked for core military requirements. In 2025, all allies meet or exceed the old 2% threshold — a dramatic change from 2014, when only three countries did. EU member states collectively reached an estimated €381 billion (2.1% of GDP) in defense spending in 2025. Explore how this compares to other fiscal priorities on our government spending by country rankings.

The Middle East: War Budgets and Structural Militarisation

The Middle East saw some of the sharpest spending increases in 2024, driven by active conflicts rather than deterrence postures. Israel's military budget surged 65% to $46.5 billion following the October 2023 Hamas attack and the subsequent operations in Gaza and southern Lebanon. At 8.8% of GDP, Israel now allocates a higher share of its economy to defense than any other OECD country — and ranks first globally in per-capita military spending at nearly $5,000 per person.

Saudi Arabia, the region's largest spender in absolute terms at an estimated $80.3 billion, maintains its position as the seventh-largest military budget worldwide. The Kingdom's spending reflects both the Yemen conflict's legacy and the broader modernization of the Saudi armed forces under Vision 2030. You can compare Israel's economy and Saudi Arabia's economy on their respective country profiles.

Ukraine and Russia: The Economics of Attrition

Ukraine's defense expenditure reached $64.7 billion in 2024 — a figure that would have been unimaginable for an economy of Ukraine's size before the war. As a share of GDP, Ukraine's military spending likely exceeds 30%, a level seen only in wartime economies. Much of this is funded by Western aid packages, but the economic strain is immense: the Ukrainian economy contracted sharply in 2022 and has only partially recovered.

Russia, meanwhile, spent $149 billion on defense in 2024, making it the third-largest military spender globally. More telling is the trajectory: Russian military expenditure has roughly tripled since 2021 in nominal terms, reflecting both the operational costs of the war in Ukraine and a broader industrial mobilization. Russia's defense budget consumed an estimated 6.7% of GDP in 2024, the highest share since the Soviet era. The Kremlin has effectively restructured its economy around the war effort, with defense and security accounting for roughly 40% of the 2025 federal budget — a level that economists warn is difficult to sustain without significant fiscal trade-offs in healthcare, education, and infrastructure.

Asia-Pacific: Quiet Buildups

China's officially reported defense budget of $314 billion (SIPRI's estimate, which exceeds Beijing's official figure) grew 7.0% in 2024, continuing a trajectory of above-GDP military spending growth that has persisted for more than two decades. The PLA's modernization program — encompassing naval expansion, missile forces, and space and cyber capabilities — makes China the world's second-largest military power by expenditure, though many analysts believe actual spending may be 40-60% higher than reported.

Japan's inclusion in the top 10, at $55.3 billion, reflects Tokyo's historic 2022 decision to double defense spending to 2% of GDP by 2027. For a country whose post-war constitution explicitly limits military capability, this represents a generational policy shift driven by North Korean missile tests, Chinese assertiveness in the Taiwan Strait, and deepening concerns about the reliability of American security guarantees. Japan's economic profile shows an economy that can absorb higher defense spending — but not without trade-offs, given persistent government debt exceeding 250% of GDP.

India, at $86.1 billion (fifth globally), continues to balance a modernization-intensive procurement program with the fiscal constraints of a developing economy. India's defense spending grew 1.6% in real terms in 2024 — modest compared to European growth rates, but reflective of a different strategic calculus. New Delhi faces a two-front challenge (China and Pakistan) while simultaneously trying to build an indigenous defense industrial base. India's defense expenditure as a share of GDP, at roughly 2.4%, has actually declined from 3.5% in the early 1990s — even as the absolute figure has risen substantially. Explore India's full economic profile.

The Macroeconomic Question: Guns vs. Everything Else

The IMF's April 2026 World Economic Outlook dedicates a chapter to the macroeconomic implications of defense spending booms, noting that large booms have become more frequent — particularly in emerging markets. In a typical boom, defense outlays increase by about 2.7 percentage points of GDP over two-and-a-half years. That is not a trivial reallocation.

For European economies already grappling with aging populations, slow productivity growth, and elevated government debt, the fiscal arithmetic of 5% GDP on defense is daunting. Germany's journey from 1.1% of GDP on defense in 2014 to its current trajectory toward 3.2% implies billions of euros diverted from other priorities — or, more likely, financed through additional borrowing. The Bank of Finland has questioned whether higher defense spending can actually boost euro area growth, noting that the multiplier effects depend heavily on whether the money is spent domestically or on imports.

This fiscal pressure is visible across the OECD. Compare defense allocations against healthcare spending and education spending by country to see the trade-offs in context. For the G7 economies, the challenge is managing rearmament without derailing fiscal sustainability. For developing nations, the calculus is starker: every dollar spent on arms is a dollar not spent on schools, hospitals, or infrastructure.

What Comes Next

The structural drivers of higher defense spending — the Russia-Ukraine war, US-China strategic competition, Middle Eastern instability, and the erosion of arms control agreements — show no signs of abating. NATO's 5% target, even if aspirational for many members, signals a decade-long upward ratchet. Poland and the Baltic states will likely reach 4-5% of GDP before 2030. Germany, France, and the UK will climb toward 3%. The United States, already spending 3.4% of GDP on defense, will face pressure to maintain or increase that share as it pivots military resources toward the Indo-Pacific.

The defense industrial base is also a constraint. Surging budgets do not automatically translate into more equipment: supply chains for precision munitions, advanced semiconductors, and naval vessels take years to scale. Europe's defense industry, fragmented across national champions, is only beginning to consolidate. The gap between political commitments and industrial capacity is likely to define defense economics for the rest of the decade.

What is clear from the data is that the post-Cold War era of declining defense budgets is definitively over. The world is spending more on arms than at any point in modern history, and the trajectory points upward. Whether that spending produces genuine security — or merely an arms race with diminishing returns — will be the defining fiscal question of the late 2020s.
