Taiwan earthquake sends shockwaves through global supply chain

In the aftermath Taiwan’s biggest earthquake in at least 25 years, several major semiconductor and electronics companies have been forced to temporarily halt operations and evacuate production facilities.

According to Jena Santoro, senior manager of global risk intelligence for Everstream Analytics, the impacts have been significant.

The earthquake has resulted in at least nine fatalities and over 900 injuries, with extensive damage to more than 100 buildings and infrastructure reported across Taiwan. More than a dozen aftershocks, some measuring above magnitude 5, have compounded the region, disrupting transportation networks, jeopardizing manufacturing operations and resulting in power outages affecting an estimated 91,000 customers. Due to rockfall and landslides, regional road and rail connections have also been disrupted.

Major players like Taiwan Semiconductor Manufacturing Co. (TSMC), United Microelectronics Corporation, and Innolux Corporation have all reported material damages, preventive shutdowns, and facility evacuations. The ripple effects are affecting global supply chains for microchips, LCD panels, integrated circuits, and more.

Authorities have closed the Suhua Highway, which connects Su’ao Township in Yilan County to Hualien City in Hualien County. Meanwhile, rail links between Yilan County and Taitung County that cross through Hualien Country remain suspended. 

With road and rail connections disrupted and power outages affecting thousands, the flow of goods and materials in and out of Taiwan face significant hurdles. As recovery efforts continue in Hualien County and assessments of damages progress, the possibility of prolonged operational halts looms. Potential aftershocks and ongoing infrastructure challenges could exacerbate supply chain disruptions in the weeks ahead.
