From COVID-19 to the Russia-Ukraine War and Middle East tensions, global conflicts have exposed the fragility of semiconductor supply chains. This article analyses how wars disrupt chips, AI, automobiles, cloud computing and the global digital economy.

Why Semiconductor Supply Chains Have Become a Geopolitical Battlefield

Semiconductors are no longer merely industrial components. They have become the foundational infrastructure of the modern economy. Smartphones, artificial intelligence systems, electric vehicles, cloud computing, defence technologies, telecommunications equipment, medical devices and industrial machinery all depend on advanced semiconductor chips. As a result, the semiconductor industry today sits at the intersection of technology, economics, trade and national security.

The global semiconductor market exceeded US$600 billion in 2024, while the broader semiconductor-enabled digital economy runs into trillions of dollars annually. Yet the industry operates through one of the most geographically concentrated and globally interdependent supply chains in the world. Design may occur in the United States, manufacturing in Taiwan or South Korea, raw material processing in China, equipment production in Japan and Europe, and assembly across Southeast Asia.

This high degree of interdependence has made the semiconductor industry extremely vulnerable to geopolitical shocks. Over the past few years, three major disruptions have fundamentally altered the global semiconductor landscape:

• the COVID-19 pandemic,
• the Russia-Ukraine War, and
• the escalation of geopolitical tensions in the Middle East affecting global shipping and energy markets.

These crises demonstrated that semiconductor supply chains are no longer purely economic systems. They have become strategic geopolitical assets. This article analyses how wars and global conflicts affect semiconductor industries, why these disruptions occur, which sectors are most exposed, and what lessons governments and businesses must learn from recent crises.

The Semiconductor Industry: A Highly Concentrated Global Network

The semiconductor supply chain is structurally fragile because no single country controls the entire ecosystem.

Table 1: Global Semiconductor Ecosystem Concentration

One of the most important structural vulnerabilities is manufacturing concentration. Taiwan Semiconductor Manufacturing Company alone produces over 90% of the world’s most advanced semiconductor chips. Meanwhile, South Korea dominates memory chips through Samsung Electronics and SK Hynix.

This concentration means that disruptions in even one region can affect industries worldwide.

COVID-19: The Shock That Exposed Global Dependence

The first major semiconductor disruption emerged during the COVID-19 pandemic.

Lockdowns across Asia, Europe and North America temporarily shut semiconductor fabrication facilities, logistics networks and electronics manufacturing plants. At the same time, global demand for digital devices surged dramatically as economies shifted toward remote work, online education and digital communication.

The automotive industry became one of the biggest casualties. Modern vehicles rely heavily on semiconductors for:

• GPS systems
• airbags
• sensors
• infotainment systems
• battery management systems in EVs

When semiconductor supplies tightened, major automakers including Toyota, Ford Motor Company and Volkswagen had to cut production or temporarily halt operations.

Table 2: Semiconductor Shortage Impact During COVID

The semiconductor shortage highlighted a critical structural problem: the world had prioritised efficiency over resilience. Supply chains were optimised for low cost and just-in-time production rather than geopolitical stability.

Russia–Ukraine War: The Raw Material Crisis

Before semiconductor supply chains could fully recover, the Russia-Ukraine War created another major disruption.

Ukraine supplied a significant share of the world’s purified neon gas, a critical input used in semiconductor lithography lasers. Russia, meanwhile, was a major exporter of palladium, another essential semiconductor material.

Table 3: Strategic Semiconductor Materials Affected by War

As the war disrupted production facilities, logistics and exports, semiconductor manufacturers faced:

• rising material costs
• delivery delays
• supply uncertainty
• increased inventory expenses

This worsened inflationary pressure across electronics markets globally.

The conflict also accelerated a broader geopolitical shift: governments increasingly began treating semiconductors as strategic national-security infrastructure rather than merely commercial products.

The Middle East and the Semiconductor Energy Problem

Recent geopolitical tensions in the Middle East further exposed another semiconductor vulnerability: energy dependence.

Semiconductor fabrication plants are among the most energy-intensive industrial facilities in the world. Advanced chip manufacturing requires:

• uninterrupted electricity
• ultra-pure water
• specialised industrial gases
• precision climate control systems

When geopolitical tensions affect oil and gas shipping routes such as the Strait of Hormuz, energy prices and shipping costs rise globally.

The semiconductor industry is therefore indirectly vulnerable to energy wars, shipping disruptions and commodity inflation.

Industries affected include:

• artificial intelligence infrastructure
• cloud computing
• smartphones
• gaming hardware
• electric vehicles
• telecommunications equipment

Because semiconductors are embedded in nearly every advanced industry, disruptions spread rapidly across the global economy.

Why Semiconductor Wars Are Different from Traditional Industrial Crises

Historically, industrial disruptions were often regional. Semiconductor disruptions are global because chips sit at the centre of interconnected supply chains.

Three factors make semiconductor conflicts structurally unique:

1. High Geographic Concentration

A large share of advanced chip production is concentrated in Taiwan and South Korea.

2. Technological Complexity

Advanced semiconductor fabrication requires:

• billions of dollars in investment
• highly specialised equipment
• extremely skilled labour
• years of technological development

This makes rapid supply-chain replacement nearly impossible.

3. Strategic Military Importance

Semiconductors power:

• AI systems
• missile guidance
• satellites
• cybersecurity infrastructure
• advanced defence systems

As a result, semiconductor policy increasingly overlaps with national security strategy.

The Rise of Semiconductor Nationalism

Recent crises have triggered a global wave of semiconductor industrial policy.

Table 4: Major Semiconductor Policy Responses

The United States introduced the CHIPS and Science Act to reduce dependence on Asian manufacturing and strengthen domestic chip production.

China accelerated investment into semiconductor self-sufficiency after facing export controls from the US.

India launched semiconductor incentive schemes to attract fabrication and packaging facilities.

The strategic shift is clear:

Countries no longer view semiconductors purely as market commodities. They now view them as strategic infrastructure.

Economic Consequences Across Industries

Semiconductor disruptions have broader economic consequences than many traditional industrial shocks because chips are deeply embedded in production systems.

Table 5: Industries Most Vulnerable to Semiconductor Disruptions

For example:

• AI data centres require advanced GPUs
• EVs require hundreds to thousands of chips per vehicle
• Cloud infrastructure depends on advanced processors and memory chips

A semiconductor shortage therefore affects productivity, prices and technological innovation simultaneously.

Lessons for Governments and Businesses

The semiconductor crises of the past five years provide several major policy lessons.

Governments Must Prioritise Supply-Chain Resilience

Efficiency alone is no longer sufficient. Countries need:

• diversified sourcing
• strategic reserves of materials
• domestic manufacturing capability
• trusted supply-chain partnerships

Businesses Must Shift Beyond Just-in-Time Models

Firms increasingly need:

• multi-country sourcing strategies
• inventory buffers
• geopolitical risk analysis
• supplier diversification

Energy Security Matters for Technology Security

Semiconductor competitiveness depends heavily on:

• stable electricity
• energy affordability
• water availability
• infrastructure resilience

Semiconductors Have Become the Oil of the Digital Era

The global semiconductor industry today resembles the oil economy of the 20th century.

In the past:

• oil shaped geopolitics
• shipping routes mattered strategically
• energy security influenced foreign policy

Today:

• semiconductors shape technological power
• chip supply chains influence industrial policy
• advanced manufacturing determines geopolitical leverage

This transformation explains why semiconductor industries are increasingly central to:

• trade wars
• export controls
• alliance systems
• industrial subsidies
• national-security doctrines

The semiconductor crises triggered by the COVID-19 pandemic, the Russia–Ukraine war and Middle East geopolitical tensions revealed a fundamental reality: the global digital economy rests on highly fragile supply chains.

Semiconductors are no longer just industrial inputs. They are strategic assets tied directly to economic stability, technological leadership and national security.

The past few years demonstrated how:

• pandemics can disrupt production
• wars can interrupt raw materials
• energy conflicts can increase manufacturing costs
• shipping tensions can destabilise supply chains

The future of the semiconductor industry will therefore depend not only on innovation, but also on resilience.

Countries that successfully combine:

• domestic manufacturing capability,
• diversified sourcing,
• energy security, and
• geopolitical risk management

will likely emerge as the technology powers of the next economic era.
