25th June 2025 At this week’s NATO summit in The Hague, a once-dismissed proposition is gaining real traction: that member states should work towards allocating 5% of GDP to defence. What began as a controversial demand from Donald Trump — decried at the time as antagonistic and outlandish — is now being seriously discussed as a necessary strategic shift in an increasingly fragmented world order. The proposal, broken down into 3.5% for core defence and 1.5% for critical infrastructure and resilience, reflects the growing realisation that conventional deterrence, cyber-security, and supply chain security are no longer optional. They are essential to political and economic stability. As Trump often argued, NATO could not rely indefinitely on disproportionate American support. Today, many of his critics now echo the same logic — albeit through gritted teeth. Yet the story is not as simple as it first appears. Economic Implications and Commodities Impact From a market perspective, the macroeconomic effects of this shift are both vast and contradictory. On the one hand, a coordinated increase in defence budgets across NATO members would inject enormous stimulus into R&D, manufacturing, and logistics, particularly if procurement is channelled into domestic industries. For commodity-focused firms, including Gapuma, a surge in infrastructure and defence-linked investment may well create more predictable demand, greater state-backed contract certainty, and more stable long-term relationships. Critically, a better-funded defence-industrial base also strengthens the resilience of strategic supply chains, including those for energy, rare earth minerals, and base metals. In other words, defence spending can act as a structural support for the commodities sector, ensuring that supply chains remain operational even during geopolitical stress or disruption. However, not all the consequences are positive. As J.P. Morgan recently warned, heightened tensions or renewed conflict in the Middle East could push oil prices to $130 per barrel, reigniting inflationary pressures already straining global economies. In a world of finite resources, increased defence and infrastructure demand may also exacerbate competition for commodities like lithium, cobalt, and copper — materials essential for both military and green technologies. This will likely drive up prices, fuel protectionism, and intensify environmental degradation as nations push harder into fragile ecosystems. Strategic Realignment or Strategic Drift? For the United States, a 5% commitment across NATO could provide the long-sought opportunity to rebalance towards the Indo-Pacific, while empowering European allies to shoulder more of their regional defence burden. But as Europe spends more, it may also demand more autonomy, and Washington’s status as prima inter pares within NATO may face growing challenges. The wider geopolitical effects remain uncertain. Greater defence spending may deter aggression — or provoke countermeasures. It may strengthen alliances — or expose fractures. Much will depend on execution, coordination, and whether 5% becomes more than just a headline figure. At Gapuma, we recognise that defence economics are increasingly central to global trade dynamics. The convergence of military preparedness and commercial resilience is not merely theoretical. It is a tangible and urgent challenge — and for forward-looking enterprises, also an opportunity.
