Global Semiconductor Supply Chains and Competition

Key Insight

The COVID-19 pandemic starkly exposed the world's deep reliance on semiconductors, triggering a 'second chip choke' that severely impacted various sectors, particularly the automotive industry. This disruption was partly due to Chinese firms stockpiling chips in anticipation of potential U.S. sanctions, but the predominant cause was massive fluctuations in demand. In 2020, as remote work became widespread, PC and data center demand surged, while car manufacturers, forecasting an economic downturn, drastically curtailed their chip orders. When automotive demand rapidly rebounded, chipmakers had already reallocated their capacity, leaving carmakers struggling to procure the hundreds of chips required per vehicle. This resulted in an estimated 7.7 million fewer cars produced in 2021 and a collective revenue loss of $210 billion for the auto industry.

Despite prevalent political and media narratives portraying the chip shortage as a crisis of supply chain fragility, the semiconductor industry exhibited remarkable resilience. In 2021, global production surpassed 1.1 trillion semiconductor devices, marking a 13% increase from 2020, indicative of robust supply rather than breakdown. The 'shortage' was primarily a demand-side phenomenon, driven by an insatiable global appetite for computing power and the carmakers' 'ill-advised cancellation of chip orders,' compounded by their just-in-time manufacturing practices that offered little buffer. The key lesson from this period is not the fragility of supply chains, but the significant concentration of profits and power within the industry's critical choke points.

Global competition for semiconductor manufacturing capacity is intensifying, with nations including the U.S., Europe, Japan, and Singapore actively seeking new investments. South Korea, through its giants Samsung and SK Hynix, aims to solidify its leading position in memory chips while expanding its role in logic chip production. President Moon Jae-in has declared a national commitment to remain a 'semiconductor powerhouse,' backed by Samsung's ambitious plans to invest over $100 billion by 2030 in logic chips, alongside comparable sums in memory production. Intel, under CEO Pat Gelsinger, has launched an aggressive multi-pronged strategy: regaining manufacturing leadership with next-generation EUV machines, establishing a foundry business to rival TSMC and Samsung, and publicly advocating for a 'balanced supply chain' through government subsidies for domestic fabs, even while paradoxically outsourcing a growing portion of its advanced chip designs to TSMC in Taiwan. This global dynamic highlights a fundamental challenge: if the U.S. increases its market share, it inherently means a decrease for another ally, as most advanced chip fabs outside China are located in U.S.-allied nations.
