Taiwan Is Facing Its Worst Rainfall in 75 Years, and the Hardest-Hit Area Is Exactly Where TSMC’s Most Advanced Fabs Are

On top of the gigantic semiconductor demand Taiwan is witnessing, the nation is experiencing a tough period with water supply, as local authorities report a 75-year low in rainfall.

Taiwan's Water Shortages Are Influencing TSMC's Largest Fab Network, But There Are No Production Concerns For Now

Taiwan is the world's semiconductor hub and is likely a chokepoint for the modern AI infrastructure buildout, given that the region hosts one of the world's most advanced fab networks and is also under consistent geopolitical pressure. At the same time, a new report by the Taiwanese media outlet Liberty Times has disclosed that the nation's western part, where the entire semiconductor industry is located, faces severe water shortages, prompting the local government to take measures to ensure a consistent supply.

The report notes that areas like Hsinchu, known for hosting TSMC's advanced fabs, are under greater pressure and have been given a "yellow" warning, as the severity there is higher than in other districts. For now, it is reported that there is no threat to the water supply to the industrial areas, but as we enter the intense heat months, the local government is eager to implement drought-resistant measures to ensure production isn't compromised. At the same time, efficiency measures are being implemented across water-dependent industries to ensure optimal resource utilization.

Water isn't the only concern for Taiwan's industrial production; another emerging threat comes from supply chain disruptions from the Middle East conflict. Asian nations are heavily dependent on the Strait of Hormuz for their LNG supply, and right now they have had to fall back on national reserves, which are only enough for 'just a few days'. Taiwan's electricity generation is currently completely dependent on LNG, and given TSMC's huge share, the situation is also brewing new trouble for the broader AI supply chain.

Given that the entire world depends on chips from Taiwan, any emerging threat to industrial production will have a much larger impact on the AI industry. For now, the local government is confident in its ability to manage supply, but considering the severity of shortages, whether water or LNG, deepens, this could disrupt production, not just at TSMC's fabs, but also other players in the supply chain.
