PARIS—For most of the postwar era, global power was defined by alliances, aircraft carriers, and reserve currencies. But we are now entering an era defined by critical infrastructure and those who finance, build, and operate it. Ports, power grids, rail corridors, data centers, and critical-mineral supply chains are no longer just “projects.” They are the operating system of sovereignty. Infrastructure—networks that move energy, goods, and data—is the industry of industries. Whoever shapes it through contracts, standards, currency denomination, and long-term maintenance (much of which is increasingly guided by data and AI-driven systems) will achieve enduring global influence.

Debates about “de-dollarization” often focus on reserve currencies. In the International Monetary Fund’s Currency Composition of Official Foreign Exchange Reserves data, the U.S. dollar accounted for roughly 57 percent of global reserves in 2025, with the euro a distant second. But official reserves are a lagging indicator. The more relevant shift concerns infrastructure.

China recognized this early. Between 2000 and 2023, it extended approximately $2.2 trillion in official loans and grants as part of its Belt and Road Initiative, much of which was invested in transportation and energy infrastructure. This model was never just about capital. By bundling finance, contractors, equipment, and digital systems, China was exporting state capacity and embedding long-term dependence. Projects like the Chancay mega-port in Peru—which is majority-owned by a Chinese operator and backed by billions in investment—illustrate how infrastructure can reconfigure trade routes and other dependencies. Likewise, the Addis Ababa–Djibouti Railway, financed largely by Chinese lending, dramatically reduced freight times between Ethiopia and the Red Sea.

The geopolitical implications of infrastructure investment are increasingly top of mind for policymakers. The prospect of Chinese involvement in airport construction in Greenland raised security concerns in both Denmark and the United States. The new contest is not simply between currencies but between competing infrastructure blocs.

For decades, U.S. influence rested on military power, the dollar, and multilateral institutions. But while this architecture still matters, it is rapidly being supplemented—and in some cases challenged—by infrastructure strategies.

Political tensions reflect this shift. In 2024, U.S. President-elect Donald Trump threatened severe tariffs against countries pursuing alternatives to dollar-based invoicing and payments. At the same time, Western economies have scaled up their own infrastructure initiatives. The G7’s Partnership for Global Infrastructure and Investment, for example, aims to mobilize $600 billion by 2027; the European Union’s Global Gateway pledges up to €300 billion ($353 billion); and the Blue Dot Network (launched by Australia, Japan, and the US) seeks to certify high-quality infrastructure standards.

Yet many countries perceive these efforts as slow and overly conditional. In a world facing climate shocks, demographic pressures, and urgent development needs, the ability to deliver infrastructure quickly often outweighs governance concerns.

Various middle powers are redefining their own strategies accordingly. India, for example, is pursuing “corridor diplomacy” by supporting projects like the Chabahar Port and the India–Middle East–Europe Economic Corridor. Rather than aligning exclusively with one bloc, it is leveraging infrastructure to hedge, diversify, and expand its own strategic autonomy.

There is also another critical shift underway. Far from being confined to steel and concrete, infrastructure geopolitics increasingly extends into compute, data, and AI. Corporate filings reveal the scale of this transition. Technology firms such as Microsoft, Alphabet, Meta, and Amazon are investing tens of billions of dollars annually in AI infrastructure, including data centers and specialized hardware. Their capital expenditures and associated depreciation now resemble those of traditional infrastructure sectors.

Semiconductor manufacturing has become a strategic chokepoint in this system. Facilities costing tens of billions of dollars anchor global supply chains and define access to advanced compute capabilities. But AI is not just another layer of infrastructure. It is meta-infrastructure that will shape how all other systems are planned, operated, and optimized. If infrastructure defines geopolitical power, AI is increasingly defining infrastructure. It can improve grid efficiency, extend the life of transport networks, and enable more precise climate-adaptation strategies.
