The microchip, once a basic part of global trade, has become the most vital geopolitical commodity. The age of super-efficient, globally concentrated semiconductor production—developed over decades with a focus on cutting costs—has come to an end. In its place, fierce competition, backed by state resources, has emerged. This competition aims not just for economic gain but for securing technological sovereignty and national security.
For leaders and tech professionals, this situation is not just another business challenge; it’s a major restructuring of the global technology system worth trillions of dollars. The key battle—the Silicon Supply Chain War—stems from the use of export controls, large subsidies for domestic industries, and the significant risks tied to dependence on advanced manufacturing in East Asia.
The Great Decoupling: From Efficiency to Resilience
For years, the semiconductor value chain operated on a global specialization model. The US dominated research and design, while fabrication was primarily in Taiwan and South Korea, with one company, TSMC, producing more than 90% of the most advanced chips. Assembly, testing, and packaging mostly took place in Southeast Asia and China. This setup maximized efficiency and kept prices 35% to 65% lower than they might have been.
However, the COVID-19 pandemic and resulting supply disruptions cost the global automotive industry billions and revealed the weaknesses in this model. The deeper concern, though, is geopolitical: the risk of conflict in the Taiwan Strait and escalating tech restrictions between the US and China.
In response, major economic blocs have launched a wave of protectionist policies that effectively require a decoupling of the supply chain along ideological lines.

The Chokepoints: Advanced Nodes and Key Equipment
The race for independence is not about all chips, but the bleeding-edge silicon required for next-generation technologies.
1.Advanced Logic Fabrication (The Taiwan Card)
The largest chokepoint is the production of leading-edge nodes (e.g., 5nm, 3nm, 2nm and beyond). These are essential for high-performance computing, AI accelerators (like NVIDIA’s GPUs), and defense applications. TSMC’s leadership in this area gives Taiwan a strategic advantage—often termed its “Silicon Shield.”
The CHIPS Act has successfully encouraged major investments, including TSMC’s $40 billion commitment to new fabs in Arizona. Analysts predict that the US will raise its overall fab capacity share from about 10% today to 14% by 2032. This marks a significant turnaround from decades of decline and is the first step toward reducing the risk of relying on a single source.
2.Manufacturing Equipment (The Dutch-Japanese-US Troika)
Another critical chokepoint is the specialized equipment needed for photolithography. Dutch company ASML has a near-monopoly on Extreme Ultraviolet (EUV) lithography machines, which are essential for making the most advanced chips. Likewise, US and Japanese companies lead the market for other critical tools and specialized chemicals.
US-led export controls have successfully persuaded allies like the Netherlands and Japan to limit the sale of advanced equipment to China. This has created a technological “ceiling” that restricts Chinese chipmakers, particularly in advanced nodes. Consequently, China has poured resources into domestic research and alternative designs, like RISC-V, to bypass US-centric intellectual property in x86 and Arm.
AI as the Ultimate Geopolitical Accelerant
The rising demand for generative AI and its core infrastructure—large language models (LLMs) and massive data centers—has increased the strategic importance of advanced chips. The computational needs for AI training and inference can grow rapidly, making access to high-bandwidth, high-performance AI accelerators (such as HBM-enabled GPUs) a key sign of future economic and military strength.
This dependency ensures that the competition in technology is not just a temporary trade issue but a long-term national priority:
– For the West: Controlling the export of advanced AI chips and manufacturing tools is crucial for national security and aims to slow the technological progress of strategic rivals.
– For China: Gaining self-sufficiency in AI chip design and manufacturing is a top strategic goal. Despite export restrictions, Chinese firms like Huawei have shown they can improve rapidly, often by getting around barriers or exploiting loopholes.
The Cost of Independence: Inefficiency and Fragmentation
The push for regional independence comes with significant economic drawbacks. Decoupling and reshoring could eliminate the $45 billion to $125 billion in savings the integrated global supply chain generated each year. New domestic fabs are necessary for strategy, but they are extremely expensive, costing more than $20 billion each.
Moreover, this fragmentation creates new obstacles for the industry:
Overcapacity Risk: Heavy state subsidies might lead to overinvestment in certain areas, like mature nodes in China. This could create pricing pressures in the future and deter further market-based investments in allied countries.
Talent Scarcity: The rapid construction of many advanced fabs in the US and Europe runs into a significant shortage of skilled engineers and technicians, which could delay the reshoring process.
Regulatory Complexity: Companies now must deal with a confusing mix of different regional standards, subsidies, and, most challenging, export control laws. This might require them to design and make different chips for various markets.
The Path Forward: Strategic Flexibility and Allied Strategy
Global executives need to shift their focus from pure efficiency to strategic resilience.
- Mandate Multi-Regional Sourcing: Chief Technology Officers should expand their sourcing strategies beyond the traditional East Asian focus, taking advantage of the new, subsidized capacities emerging in the US, Europe, Japan, and India.
- Invest in Foundational Talent: Companies should prioritize investing in workforce development and training—especially for specialized engineering roles. This is as important as spending on new equipment to ensure long-term success in domestic manufacturing.
- Harden the Software/Design Layers: Since full self-sufficiency will take over a decade, firms must also invest in measures to protect against hardware vulnerabilities and maintain chip security, regardless of origin.
The Silicon Supply Chain War represents a lasting change in global manufacturing. While achieving microchip independence is challenging and costly, it has become a critical strategic requirement in a more divided world. Leaders who manage this shift well will secure not only market share but also the essential technology for their nations’ economic and security futures.
