A conflict over Taiwan would shock the global semiconductor industry, with Japan, South Korea and the Philippines being the hardest hit, the Economist Intelligence Unit (EIU) said in its latest report.
The Economist Group’s analysis unit — which warned of “devastation” to Asia’s economy in the event of conflict across the Taiwan Strait — said that it was assuming a hypothetical full-conflict scenario, involving direct military participation by Taiwan, China and the US, with the escalation initiated by China and the US’ participation activating its regional security alliances.
The report said that the risk of a direct Chinese military assault on Taiwan was “very unlikely.”

However, Asian economies have significant vulnerabilities tied to Taiwan, especially with regard to advanced chip manufacturing, it said.
A previous EIU report in March said that Taiwan makes 60 percent of the world’s semiconductors and 90 percent of advanced chips.
At best, a conflict would disrupt air and maritime links needed to import items necessary for chip fabrication and exporting chips, the report released this week said.
“At worst, a war would result in the complete destruction of Taiwan’s chipmaking facilities,” it added.
Either outcome would hinder swathes of the global economy, affecting the production of smartphones, computers, home appliances and vehicles, and limiting other sectors, including financial services, it said.
Taiwan is critical to the chip industry, as it is the only place that makes the most advanced semiconductors — those using process technologies of less than 10 nanometers, the report said.
South Korea and Japan would be the obvious alternatives to replace Taiwan’s advanced chipmaking operations, but that would require an effort spanning years and massive investments, it said.
“China is a major exporter of semiconductors, but in the event of a cross-strait conflict we would expect sourcing from the Chinese market to be difficult, not only as a result of disrupted factory production and logistics, but also as a consequence of likely trade and financial prohibitions by the US and others,” the EIU report said. “China could also impose export bans on countries judged to be hostile towards its role in the conflict.”
Japan, South Korea and the Philippines would be the most exposed in the event of a war, while Australia, Hong Kong, Malaysia, Thailand and Vietnam would face “severe exposure,” it said.
It excluded Taiwan and China from its risk of exposure analysis.
The countries most exposed to the economic consequences of war are generally those that might face direct military action due to being members of US-led security alliances and hosting US military bases, it said, adding that heavy reliance on Taiwanese chips was a secondary factor.
“We view the Philippines, Japan and South Korea as the countries most exposed to a conflict over Taiwan,” the report said. “Our assessments for these three countries reflect geopolitical realities, as well as heavy reliance on trade with China. Their geographic proximity to the Taiwan Strait, alongside their roles as important US treaty allies, suggests a high risk that they will be drawn into a conflict.”
“The hosting of US military bases in all three of these countries, in particular, also highlights their vulnerability to a pre-emptive Chinese attack,” it said.
Hong Kong’s vulnerability stems from damaging economic sanctions that the West would likely impose on China and its territories should Beijing invade Taiwan, it said.
A Chinese freighter that allegedly snapped an undersea cable linking Taiwan proper to Penghu County is suspected of being owned by a Chinese state-run company and had docked at the ports of Kaohsiung and Keelung for three months using different names. On Tuesday last week, the Togo-flagged freighter Hong Tai 58 (宏泰58號) and its Chinese crew were detained after the Taipei-Penghu No. 3 submarine cable was severed. When the Coast Guard Administration (CGA) first attempted to detain the ship on grounds of possible sabotage, its crew said the ship’s name was Hong Tai 168, although the Automatic Identification System (AIS)
An Akizuki-class destroyer last month made the first-ever solo transit of a Japan Maritime Self-Defense Force ship through the Taiwan Strait, Japanese government officials with knowledge of the matter said yesterday. The JS Akizuki carried out a north-to-south transit through the Taiwan Strait on Feb. 5 as it sailed to the South China Sea to participate in a joint exercise with US, Australian and Philippine forces that day. The Japanese destroyer JS Sazanami in September last year made the Japan Maritime Self-Defense Force’s first-ever transit through the Taiwan Strait, but it was joined by vessels from New Zealand and Australia,
SECURITY: The purpose for giving Hong Kong and Macau residents more lenient paths to permanent residency no longer applies due to China’s policies, a source said The government is considering removing an optional path to citizenship for residents from Hong Kong and Macau, and lengthening the terms for permanent residence eligibility, a source said yesterday. In a bid to prevent the Chinese Communist Party (CCP) from infiltrating Taiwan through immigration from Hong Kong and Macau, the government could amend immigration laws for residents of the territories who currently receive preferential treatment, an official familiar with the matter speaking on condition of anonymity said. The move was part of “national security-related legislative reform,” they added. Under the amendments, arrivals from the Chinese territories would have to reside in Taiwan for
CRITICAL MOVE: TSMC’s plan to invest another US$100 billion in US chipmaking would boost Taiwan’s competitive edge in the global market, the premier said The government would ensure that the most advanced chipmaking technology stays in Taiwan while assisting Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) in investing overseas, the Presidential Office said yesterday. The statement follows a joint announcement by the world’s largest contract chipmaker and US President Donald Trump on Monday that TSMC would invest an additional US$100 billion over the next four years to expand its semiconductor manufacturing operations in the US, which would include construction of three new chip fabrication plants, two advanced packaging facilities, and a research and development center. The government knew about the deal in advance and would assist, Presidential
