Fragile Supply Lines: What a Hormuz Disruption Reveals About India’s Semiconductor Ambitions

Key Highlights

A potential disruption in the strait of Hormuz has drawn attention to hidden vulnerabilities in India’s semiconductor ecosystem, especially in critical inputs like industrial gases, petrochemicals, and stable power supply. This article explains how global energy routes intersect with chip manufacturing, why India’s supply chain remains exposed despite policy efforts, and what risks and opportunities lie ahead as the country works to build a resilient semiconductor industry.

Understanding the Issue

India’s push to become a global semiconductor manufacturing hub is facing an unexpected stress test: the fragility of global supply chains tied to energy routes. The Strait of Hormuz, a narrow but strategically vital passage in the Middle East, handles a significant share of the world’s oil and liquefied natural gas (LNG) shipments. Any disruption here can ripple across industries far beyond energy—including semiconductors.

While chips are often associated with cutting-edge technology, their production depends heavily on foundational sectors like petrochemicals, industrial gases, and uninterrupted electricity. A disruption in Hormuz threatens these inputs, exposing weak links in India’s evolving semiconductor ecosystem.

Why This Matters Now

India has made strong policy moves in recent years to establish domestic semiconductor manufacturing. Incentives, partnerships, and infrastructure projects aim to reduce reliance on imports and position India as an alternative to established hubs in East Asia.

However, semiconductor fabrication (fab) facilities are among the most resource-intensive industrial operations in the world. They require:

• Ultra-pure gases such as neon, argon, and nitrogen
• Petrochemical derivatives used in photoresists and chip processing
• Continuous, high-quality power with minimal interruptions

Many of these inputs are either imported directly or indirectly depend on global energy markets. This is where the Strait of Hormuz becomes critical.

How the Semiconductor Supply Chain Connects to Energy Routes

To understand the risk, it helps to look at how deeply interconnected these sectors are.

1. Industrial Gases

Semiconductor manufacturing relies on specialty gases for etching, deposition, and cleaning processes. These gases are often derived from energy-intensive production methods. Rising energy costs or supply disruptions can directly affect availability and pricing.

2. Petrochemicals

Chip fabrication uses a range of petrochemical-based materials. These originate from crude oil refining and chemical processing industries—both heavily dependent on stable oil supply chains.

3. Electricity

A semiconductor fab cannot tolerate even brief power fluctuations. Stable electricity often depends on natural gas and coal, both influenced by global energy prices.

When oil and gas flows through the Strait of Hormuz are disrupted, it can lead to:

• Higher fuel costs
• Supply shortages
• Increased input costs for chip manufacturing

Historical Context: India’s Semiconductor Journey

India’s semiconductor ambitions are not new. Efforts date back decades, but multiple challenges stalled progress:

• High capital costs
• Lack of ecosystem support
• Dependence on imports for raw materials

In recent years, geopolitical shifts and supply chain disruptions—especially during the COVID-19 pandemic—have revived interest in domestic chip production.

Government initiatives have aimed to address these gaps by:

• Offering financial incentives to manufacturers
• Encouraging global partnerships
• Investing in infrastructure and research

Despite these efforts, the supply chain remains globally intertwined.

A Closer Look at the Weak Links

The current situation highlights three key vulnerabilities:

Industrial Gases: Limited Domestic Capacity

India produces some industrial gases, but high-purity semiconductor-grade gases often require advanced processing and infrastructure. A large portion still depends on imports or energy-intensive production.

Petrochemicals: Import Dependence

India imports a significant share of crude oil. This dependency extends to petrochemical derivatives used in chip manufacturing.

Power Supply: Reliability Challenges

Although India has made progress in expanding electricity access, ensuring uninterrupted, high-quality power for semiconductor fabs remains a challenge. Energy price volatility can further complicate this.

Who Is Affected—and How

Semiconductor Manufacturers

Companies planning to set up fabs in India face uncertainty around input costs and supply reliability. This can influence investment decisions and timelines.

Electronics Industry

India’s growing electronics manufacturing sector depends on steady chip supplies. Any disruption can affect production of smartphones, consumer electronics, and automotive components.

Consumers

Higher production costs may eventually translate into increased prices for electronic goods.

Government and Policymakers

Efforts to build a self-reliant semiconductor ecosystem could be slowed, requiring policy adjustments and additional investments.

---

Broader Economic and Strategic Impact

The semiconductor industry is often described as the backbone of the digital economy. Disruptions in this sector can have wide-ranging effects:

• Slower growth in technology manufacturing
• Increased import bills
• Reduced competitiveness in global markets

From a strategic perspective, dependence on external supply chains can limit a country’s ability to respond to global shocks.

---

How the Situation Developed

The current vulnerability is the result of several overlapping factors:

Globalization of Supply Chains

Over decades, semiconductor production has become highly specialized and geographically concentrated. Different regions handle different parts of the value chain.

Energy Dependence

Industrial processes rely heavily on fossil fuels. Even as renewable energy grows, oil and gas remain central to many sectors.

Limited Domestic Ecosystem

India’s semiconductor push is relatively recent. Supporting industries—such as specialty chemicals and high-purity gas production—are still developing.

Risks Ahead

If disruptions in the Strait of Hormuz were to intensify or persist, several risks could emerge:

• Rising input costs for semiconductor production
• Delays in fab construction and operations
• Increased reliance on imports of finished chips
• Pressure on government budgets due to higher energy costs

---

Possible Solutions and Policy Responses

Addressing these vulnerabilities requires a multi-layered approach.

Diversifying Energy Sources

Reducing dependence on imported oil by expanding renewable energy and alternative fuels can help stabilize input costs.

Building Domestic Capabilities

Investing in local production of industrial gases and petrochemicals can reduce reliance on global supply chains.

Strengthening Infrastructure

Reliable power supply and advanced industrial infrastructure are critical for semiconductor manufacturing.

Strategic Reserves

Maintaining reserves of critical materials can provide a buffer during disruptions.

Global Partnerships

Collaborating with other countries can help secure supply chains and share technological expertise.

What Happens Next?

India’s semiconductor journey is still in its early stages. The current situation serves as a reminder that building a resilient ecosystem requires more than just setting up fabs.

In the coming years, the focus is likely to shift toward:

• Strengthening upstream supply chains
• Reducing exposure to global disruptions
• Integrating energy and industrial policy

While challenges remain, they also offer an opportunity to build a more robust and self-sufficient system.

---

A Balanced Outlook

The risks posed by potential disruptions in the Strait of Hormuz are real, but they are not insurmountable. Many countries face similar challenges, and solutions are already being explored globally.

For India, the path forward involves careful planning, sustained investment, and coordination across sectors. The semiconductor industry is complex, but with the right strategies, it can become more resilient over time.

Conclusion

The intersection of global energy routes and semiconductor manufacturing highlights how interconnected modern industries have become. A disruption in one part of the world can have far-reaching effects on technology production elsewhere.

India’s ambitions in semiconductors are significant, but achieving them will require addressing foundational vulnerabilities in gases, petrochemicals, and power. The current situation is less a setback and more a wake-up call—one that could ultimately lead to stronger, more resilient systems if addressed thoughtfully.
