Economic interdependence is increasingly becoming a source of strategic leverage. Governments can exploit concentrated supply chains, critical maritime routes and financial networks to impose costs on rivals. China’s dominance in rare-earth processing gives Beijing influence over industries that depend on specialised minerals, while Iran’s position near the Strait of Hormuz creates risks for international energy transport.
These vulnerabilities are encouraging governments to diversify supply routes, expand domestic production and build alternative sources of critical materials. Saudi Arabia and the United Arab Emirates have invested in infrastructure that can move some oil exports without transiting the Strait of Hormuz. The United States has also pursued policies intended to strengthen domestic critical-mineral supply chains and reduce dependence on Chinese processing.
Financial interdependence presents a different challenge. The US dollar remains the leading global reserve currency, although its share of reported foreign-exchange reserves has fluctuated. The International Monetary Fund reported a dollar share of 56.70 per cent in the second quarter of 2026. These developments illustrate the broader strategic problem: countries can reduce individual vulnerabilities, but replacing deeply established supply chains and financial networks takes time.
Economic coercion exposes the difference between announcing strategic independence and developing the industrial capacity needed to achieve it. Governments can subsidise domestic mining, finance alternative processing facilities and encourage allied production. However, complex refining processes require specialised equipment, skilled personnel, environmental approvals and reliable commercial demand.
Rare-earth processing illustrates this challenge. Establishing alternative capacity involves more than extracting minerals; manufacturers also need dependable separation, refining and component-production facilities. Defence contractors may therefore remain exposed to supply disruptions even when alternative mines or procurement agreements exist. Rare-earth processing illustrates this challenge.

Stockpiling can provide temporary resilience, but its effectiveness depends on inventory levels, consumption rates, material specifications and the duration of a disruption. Without reliable data, predicting when shortages would force ammunition-production cuts is speculative. A more robust strategy would combine carefully targeted reserves with diversified suppliers, domestic processing and recycling.
For India, the lesson extends beyond rare earths. Energy imports, semiconductor components, specialised chemicals and maritime transport can all create strategic vulnerabilities. Resilience requires identifying critical dependencies and building credible alternatives before a crisis occurs.
