When Economies Turn Inward

Across Europe and beyond, governments are recalibrating economic strategy toward continuity, control and strategic exposure, with global efficiency no longer serving as the primary organising principle. Trade continues to play a central role, and interdependence remains a defining feature of the global economy. Its terms, however, are now defined by conditions tied to security, resilience and political alignment.

From Efficiency to Endurance

For decades, economic policy prioritised scale, cost reduction and just-in-time logistics. Supply chains were designed to minimise disruption, assuming political stability as a given. That assumption has become less reliable.

In Europe, industrial strategy is now framed explicitly around resilience. Energy, food systems, semiconductors, pharmaceuticals and critical infrastructure are increasingly treated as strategic assets, no longer viewed solely as neutral market goods. The EU's Critical Raw Materials Act, adopted in 2024, reflects how acute that reassessment has become. Europe currently depends on China for 95% of its rare earth extraction. The Act's target is to bring that figure below 42%. The gap between those two numbers is the measure of the work ahead.

Industrial Policy Re-enters the Centre

In the United States, industrial policy has returned as a core instrument of economic governance. Tariffs, targeted subsidies and investment screening mechanisms are framed through the lens of national security, with trade optimisation no longer serving as the primary reference point. The objective centres on maintaining production capacity and technological capability under conditions of pressure.

The clearest illustration is TSMC's semiconductor complex in Arizona, now the largest foreign direct investment project in American history at $165 billion. What began as a straightforward reshoring initiative has become something more revealing: a shift in the logic of competition itself. The market is no longer racing for the smallest chip node. It is racing for the most resilient and politically aligned manufacturing footprint. Cost has not disappeared as a consideration. It has been subordinated to continuity.

Financial institutions increasingly factor this reality into long-term forecasts. Capital allocation is adjusting to a world in which political alignment, regulatory exposure and supply security influence returns as much as cost efficiency. Economic nationalism, in this sense, is less an ideology than a planning framework.

Strain Within the Global Market Architecture

The effects are visible even inside long-standing economic structures. The European Single Market, built on the free movement of goods, capital, services and labour, is under pressure from targeted state support and regulatory divergence. While the framework remains intact, its operation has become more discretionary.

Germany's export-driven model, long supported by stable global demand and open trade routes, is undergoing sustained reassessment. Policymakers are increasingly focused on reinforcing domestic value chains and reducing exposure to geopolitical disruption, while attempting to preserve competitiveness. Within this context, the long-term position of Germany's automotive industry, historically central to the country's economic strength, is facing growing uncertainty as global markets fragment and industrial policy priorities evolve.

These developments do not point to the end of global trade. They indicate a more selective and conditional approach to openness, shaped by strategic considerations rather than market access alone.

There is an uncomfortable irony in this moment. Europe built its postwar identity on the rejection of economic nationalism, on the conviction that open markets and shared institutions were the antidote to the conflicts that had devastated the continent. Trump's trade war has not simply disrupted that architecture. It has forced Europe into the same defensive logic it was designed to transcend. The turn inward is not a choice so much as a response, and that distinction matters.

Supply Chains as Strategic Systems

Supply chains are being redesigned with political risk as a core variable, and the consequences of ignoring that variable are no longer theoretical.In May 2025, Ford shut down its Chicago assembly plant for three weeks after China imposed export controls on rare earth materials in response to escalating trade tensions.The shortage was not of finished goods or components, but of high-powered magnets, an input so specific and so concentrated in a single country's supply that no contingency had been prepared. Export controls on strategic materials, particularly those essential for energy transition technologies, now illustrate how a single state decision can halt industrial production on another continent. Companies are responding by shortening supply lines, diversifying suppliers and accepting higher operating costs in exchange for continuity. Redundancy is now understood as a form of risk insurance, not over-engineering.

Openness, Reframed

Economic nationalism does not eliminate international cooperation, but it changes its character. Trade agreements continue to progress, including large-scale arrangements such as the EU-Mercosur framework. These agreements are now negotiated with safeguards and adjustment mechanisms built in from the outset. Openness operates within boundaries that did not previously exist, and those boundaries are being drawn by strategic priorities, not market logic alone.

Strategic Implications

The current trajectory reflects a broader reassessment of how economies function in an environment marked by geopolitical rivalry, resource competition and systemic risk.

For governments, economic policy increasingly operates as an extension of security policy. For businesses, resilience has moved to the centre of strategic decision-making. Supply chains that are slower, more costly and subject to greater regulation are now treated as baseline assumptions within long-term planning.

Economic nationalism, reasserted under external pressure, is not the same as the nationalism that preceded European integration. But it draws on the same instincts. The question for Europe is whether it can manage that tension consciously, or whether the response to one form of disruption quietly becomes a source of another.
