The World Is Spending More on Defence, But Who Is Paying the Price for Peace? 

There’s a strange kind of math happening around the world right now. Governments keep saying they can’t afford better hospitals, cheaper food, or stronger safety nets. Yet somehow, there’s always money for tanks, missiles, and fighter jets.

In 2025, the world spent almost $2.9 trillion on its militaries, the highest figure ever recorded, and the eleventh year in a row that number has gone up. That’s not a typo. Eleven straight years of growth, even through pandemics, inflation crises, and cost-of-living protests on nearly every continent. So here’s the real question nobody in power wants to answer directly: if this is what it costs to buy “peace,” who’s actually paying for it?

Why Global Defence Spending Is Exploding

According to the Stockholm International Peace Research Institute (SIPRI), the world’s most trusted tracker of military budgets, global military expenditure climbed to $2,887 billion in 2025, pushing military spending as a share of global GDP to 2.5 percent, its highest level since 2009. 

Europe is the biggest driver of this surge. The continent’s defence spending jumped 14 percent to $864 billion, the fastest annual increase among NATO’s European members since 1953. Germany, once famously cautious about military budgets, crossed the 2 percent of GDP threshold for the first time since 1990. The reasons aren’t mysterious. The war in Ukraine hasn’t ended. Tensions between the US and China over Taiwan and the Indo-Pacific keep simmering. Instability in the Middle East hasn’t gone away. Every government now points to “the current moment” as justification for bigger budgets. Even the United States, which pulled back slightly in 2025 after cutting aid to Ukraine, isn’t stepping away from the trend. Congress has already approved over $1 trillion in defence spending for 2026, with a possible rise to $1.5 trillion in 2027 if new budget proposals go through. 

The Arms Race Nobody Voted For

SIPRI researchers don’t sugarcoat it. Xiao Liang, a researcher with SIPRI’s military expenditure programme, said this growth will “probably continue through 2026 and beyond” given ongoing crises and long-term military targets many countries have already locked in. 

It’s worth pausing on that phrase “long-term targets.” NATO’s 2025 summit didn’t just approve current spending; it raised the alliance’s target to 5 percent of GDP by 2035. That’s not a temporary emergency measure. That’s a permanent shift in national priorities, written into policy for the next decade. And there’s a transparency problem baked into it too. SIPRI researchers flagged that vague definitions of “defence-related” spending risk encouraging creative accounting pointing to Italy’s attempt to count a bridge construction project as military expenditure. If a bridge can be a warship on paper, how much of this spending is really about security, and how much is bureaucratic sleight of hand?

So Who’s Actually Footing the Bill?

Here’s where it gets personal. Defence budgets don’t materialise out of thin air; they come from the same pot of money that funds hospitals, schools, pensions, and roads. When a government decides billions more will go toward missiles and personnel, something else usually gets quietly trimmed. Public healthcare waits get longer. University grants shrink. Infrastructure projects get delayed “for now.” Inflation-hit families are told to tighten their belts, even as defence contractors report record profits.

Global spending per person on the military reached $352 in 2025 money that, in another world, could have gone toward clean water systems, teacher salaries, or disaster relief for the communities that actually need it. This isn’t unique to wealthy nations either. Brazil raised its military spending by 13 percent to $23.9 billion in 2025, and South Korea increased its defence budget to $47.8 billion. Developing economies with genuine poverty and infrastructure gaps are being pulled into the same spending spiral as the world’s richest nations. 

The Human and Economic Fallout

Economists have long warned that heavy defence spending, unlike investment in health or education, tends to create fewer long-term jobs and less broad economic benefit per dollar spent. It boosts specific industries, arms manufacturers, defence contractors, shipbuilders but doesn’t necessarily lift wages or living standards for the average household. Meanwhile, public frustration is growing. Across Europe, cost-of-living protests have collided with headlines about record defence budgets, creating an uncomfortable optics problem for governments: how do you ask citizens to accept austerity while simultaneously funding the biggest military buildup since the Cold War?

There’s also a psychological cost. Constant talk of rearmament, war readiness, and “5 percent of GDP by 2035” targets doesn’t exactly inspire calm. It normalises the idea that conflict is inevitable, rather than something to actively prevent through diplomacy.
