A recent analysis on a YouTube channel questions the resilience of Taiwan's "silicon shield" — a term describing the island's dominant position in semiconductor chip manufacturing, seen as a strategic bulwark protecting it from geopolitical pressures.
The video emphasizes that although Taiwan currently accounts for over 60% of global advanced chip production and holds nearly 90% of the market for sub-7 nanometer processors, these advantages are being challenged by factors such as the US-China trade war, diversification demands from Western governments, and the forced expansion of major corporations like TSMC abroad.
Meanwhile, the rise of new chip manufacturing centers in the US, Japan, and Europe — backed by massive subsidies — is gradually eroding Taiwan's monopoly, especially amid growing risks of supply chain disruptions due to tensions in the Taiwan Strait.
The video concludes that Taiwan's "silicon shield," while still a valuable strategic asset, must adapt to a new reality where major powers view chip security as a survival issue, forcing Taiwan's semiconductor industry to face both opportunities and challenges in the global supply chain restructuring process.
