When Trade Becomes a Battlefield
For much of the postwar era, economic interdependence was sold as a guarantor of peace. The logic was straightforward: nations deeply enmeshed in each other's supply chains, financial systems, and trade flows would have too much to lose from open conflict. That assumption is now under serious strain. Across multiple continents, governments are wielding tariffs, sanctions, export controls, and investment restrictions not as tools of economic management, but as instruments of strategic coercion.
The Mechanics of Economic Coercion
The shift did not happen overnight. Sanctions regimes — long a feature of foreign policy — expanded dramatically following the post-2001 security environment, and then again after Russia's annexation of Crimea in 2014. By the time Western governments imposed sweeping financial and energy sanctions on Russia following the full-scale invasion of Ukraine in 2022, the infrastructure for economic warfare was already mature and well-tested.
What changed was the scale and ambition of these tools. Blocking a country from the SWIFT international payments system, restricting access to advanced semiconductor technology, or threatening secondary sanctions against third-party nations — these are not marginal policy adjustments. They are designed to restructure the economic environment around a targeted state, forcing painful choices between geopolitical alignment and economic access.
The United States has been the most prominent practitioner of this approach, but it is far from alone. China has deployed informal trade boycotts against countries that have made political decisions Beijing dislikes — restricting imports from Australia following calls for a COVID-19 inquiry, and applying pressure on Lithuania after Vilnius allowed Taiwan to open a representative office under its own name. The European Union, historically reluctant to use economic leverage aggressively, has moved toward greater use of trade defense instruments and is developing an anti-coercion mechanism specifically designed to push back against such pressure.
The Structural Consequences
The consequences of this shift extend well beyond the targeted states. When economic relationships are perceived as potential vulnerabilities rather than mutual benefits, governments and corporations begin to restructure accordingly. Supply chain diversification — or "de-risking," as policymakers have taken to calling it — accelerates. Investment decisions factor in geopolitical risk in ways that would have seemed excessive a generation ago.
This restructuring carries real costs. Efficiency losses from duplicated supply chains, the price premium of sourcing from politically aligned partners rather than the cheapest available supplier, and the administrative burden of navigating an increasingly complex web of export controls all weigh on economies. The global trading system, built painstakingly through the GATT and WTO frameworks over decades, was premised on separating commerce from politics as far as possible. That separation is dissolving.
Smaller and middle-income economies face a particular dilemma. Many lack the leverage to resist pressure from larger powers, yet face demands — explicit or implicit — to choose sides in economic disputes that originate far from their borders. Nations in Southeast Asia, Africa, and Latin America have found themselves navigating competing pressures from Washington and Beijing simultaneously, with economic access dangled as both incentive and threat.
A New Kind of Deterrence
What is emerging resembles a new doctrine of economic deterrence — parallel to but distinct from military deterrence. States accumulate economic leverage the way they once accumulated arms: not necessarily intending to use it, but ensuring that adversaries understand the cost of confrontation. The possession of dominant positions in critical supply chains, reserve currencies, or advanced technology becomes a form of strategic power in itself.
The danger in this doctrine is that economic weapons, unlike military ones, are harder to keep contained. Sanctions spread their effects through global markets unpredictably. Export controls on one technology ripple into sectors far removed from the original target. A world in which economic interdependence functions primarily as a system of mutual hostages is a less stable one — and one that serves the interests of ordinary citizens poorly.
Whether the international community can develop norms to govern the use of economic coercion — as it has, imperfectly, for military force — remains an open question. The architecture for doing so does not yet exist.
Remaining Questions
Can multilateral institutions such as the WTO be reformed to adjudicate economic coercion disputes effectively? How will non-aligned nations build collective leverage against pressure from major powers? And at what point does the fragmentation of the global trading system become self-reinforcing and irreversible?
