For much of the past three decades, globalization emphasized efficiency, cost reduction, and the expansion of cross-border production networks. In recent years, however, disruptions — including geopolitical tensions, supply chain shocks, and intensifying technological competition — have exposed vulnerabilities within these highly interconnected systems. As a result, economic security is increasingly viewed as a framework for strengthening resilience in the global economy.

What is economic security?

Economic security refers to a country’s ability to sustain reliable access to essential goods, technologies, and infrastructure while limiting exposure to systemic disruptions or external pressure.

The concept reflects the reality that economic interdependence can generate both benefits and vulnerabilities. Global trade and investment enable countries to specialize, innovate, and grow more efficiently. At the same time, heavy reliance on a small number of suppliers, markets, or technologies can create risks if those relationships are disrupted by conflict, political tension, or supply shocks.

Economic security therefore sits at the intersection of trade policy, industrial strategy, and national security. Rather than seeking complete economic self-sufficiency, governments increasingly focus on managing risk within an interconnected global economy.

Core dimensions of economic security

In practice, economic security policies tend to focus on three areas: protecting critical infrastructure, safeguarding strategic technologies, and strengthening supply chain resilience.

Critical infrastructure

Modern economies depend on complex physical and digital infrastructure systems. Energy networks, transportation corridors, telecommunications systems, financial infrastructure, and data networks all support the functioning of economic activity.

Disruptions to these systems — whether caused by cyberattacks, geopolitical conflict, natural disasters, or supply shortages — can quickly cascade across the wider economy. Interruptions to energy supply, port operations, or digital communications can halt production, disrupt trade flows, and affect multiple industries simultaneously.

Governments therefore increasingly treat certain infrastructure sectors as strategically sensitive. Policies aimed at protecting these systems often include regulatory oversight, foreign investment screening, cybersecurity requirements, and cooperation with trusted international partners.

Strategic technologies

Technological capability has become a central element of both economic competitiveness and national security. Advanced semiconductors, artificial intelligence systems, quantum computing, and biotechnology are frequently described as dual-use technologies because they have both commercial and military applications.

Access to these technologies can influence industrial competitiveness, innovation capacity, and defense capabilities. As a result, governments increasingly seek to maintain leadership or secure access in strategically important technological sectors.

Policy tools used to manage technological security include export controls, public investment in research and development, industrial policy programs, and collaboration with allied countries on technology governance and standards.

Supply chain resilience

Global value chains have enabled firms to reduce costs and specialize production across multiple locations. While these networks have delivered significant efficiency gains, they can also create vulnerabilities when production is concentrated in a limited number of countries or firms.

The COVID-19 pandemic demonstrated how disruptions in one part of the world can ripple through global supply chains. Shortages of semiconductors, medical equipment, and other intermediate inputs affected production across multiple industries.

Geopolitical tensions have reinforced concerns about similar vulnerabilities in areas such as critical minerals, energy supplies, and advanced manufacturing inputs.

In response, policymakers and firms increasingly emphasize supply chain resilience. Strategies include diversifying suppliers, expanding production in multiple locations, building strategic stockpiles of key inputs, and strengthening regional production networks.

One analytical tool used to evaluate supply concentration is the Herfindahl-Hirschman Index (HHI), which measures the degree of market concentration among suppliers. Highly concentrated supply structures may indicate greater vulnerability in sectors considered strategically important.

How economic security is shaping trade policy

The growing emphasis on economic security is reshaping the international trade policy landscape.

Policies designed to manage economic risks — such as export controls, investment screening mechanisms, technology restrictions, and industrial subsidies — can influence global competition and market access. At the same time, policymakers continue to recognize the importance of open trade for economic growth, innovation, and development.

Balancing these objectives has become a central challenge for governments. Strengthening resilience requires managing strategic dependencies without undermining the international cooperation that enables global trade to function.

As a result, economic security increasingly shapes debates surrounding:

Supply chain diversification
Strategic industrial policy
International technology governance
Trade rules addressing subsidies and state support

These discussions reflect a broader shift in how policymakers evaluate globalization: resilience and strategic stability are now considered alongside efficiency and cost reduction.

Why economic security matters

Economic security reflects a changing perspective on globalization and economic interdependence. While open trade and global supply chains continue to generate significant economic benefits, recent disruptions have underscored the importance of managing strategic vulnerabilities.

Governments are therefore placing greater emphasis on protecting critical infrastructure, maintaining technological capabilities, and strengthening supply chain resilience.

Understanding economic security requires recognizing how economic relationships intersect with strategic considerations. The concept highlights the need to manage risks within an interconnected global economy while preserving the benefits of an open and rules-based trading system.
