Shares of handset chip designer MediaTek Inc (聯發科) tumbled nearly 10 percent in Taipei yesterday, as Washington’s expanded ban on Huawei Technologies Co’s (華為) access to US technology and software affected its suppliers.
The sell-off was sparked by the US Department of Commerce’s announcement on Monday of changes that build on restrictions announced in May, adding 38 Huawei affiliates to an economic blacklist and imposing license requirements on any chip procurement transactions.
The new regulations aim to further limit Huawei from obtaining foreign-made chips developed or produced from US software or technology, the department said.

The new rules also “prevent Huawei’s attempts to circumvent US export controls to obtain electronic components developed or produced using US technology,” it said.
Investors were concerned that the latest restrictions would prevent Huawei from obtaining chips from MediaTek and other suppliers that use US technology, software and even equipment for designing and manufacturing chips.
MediaTek said in a regulatory filing yesterday that the US’ latest rules “should not have a significant impact on the company’s operation in the short term.”
“The company is closely monitoring any changes in the US’ export restrictions,” it said.
MediaTek shares dipped 9.93 percent to close at NT$617, with a record-high daily turnover of 42.33 million shares.
Shares of Novatek Microelectronics Corp (聯詠) and Realtek Semiconductor Corp (瑞昱), whose chip designs are also used by Huawei, dropped 8.13 percent and 5.24 percent respectively.
“The Chinese firm has tended to use more MediaTek chips over the past six or nine months due to the US-China trade friction,” Eric Chen (陳慧明), managing partner at Cornucopia Capital Partner Ltd (聚芯資本), said by telephone.
“However, the US’ export controls deprive MediaTek of such advantages over US rival Qualcomm Inc, as any chips shipped from either MediaTek or Qualcomm would be subject to the [US] commerce department’s review,” Chen said.
Yuanta Securities Investment Consulting Co (元大投顧) said in a research note that the latest US ban might only affect MediaTek negatively in the short term, if China’s de-Americanization policy regarding its supply chains continues.
The US ban could result in a reduction of shipments in the fourth quarter, Taiwan Institute of Economic Research (台灣經濟研究院) researcher Arisa Liu (劉佩真) said by telephone.
“The stock price of MediaTek has inflated significantly over the past months on speculation that MediaTek would benefit from the US’ ban on Huawei’s access to US technology in May,” Liu said, adding that MediaTek was originally expected to supply high-end 5G chips for Huawei’s smartphones after the Chinese technology giant ran out of chips designed by its semiconductor arm, HiSilicon Technologies Co (海思半導體).
As of yesterday, MediaTek shares had surged more than 50 percent since the commerce department announced restrictions on Huawei in May.
In the long term, MediaTek might fill the loss of orders from Huawei by securing new orders from Chinese smartphone makers, including OPPO Mobile Telecommunications Corp (歐珀移動), Vivo Communication Technology Co (維沃移動通信) and Xiaomi Inc (小米), Liu said.
OPTIMISTIC: The DGBAS sharply upgraded its GDP growth estimate from 3.54 percent to 7.71 percent after the Taiwan-US trade agreement signing and given AI optimism The US imported more from Taiwan than China for the first time in decades, as US President Donald Trump’s tariffs reshape trade flows while a global boom in artificial intelligence (AI) fuels demand for tech products. US purchases of goods from China plunged almost 44 percent in December last year from 2024 to US$21.1 billion, US Department of Commerce data showed on Thursday. By contrast, shipments from Taiwan more than doubled during the same period to US$24.7 billion. The soaring Taiwanese shipments to the US reflect the huge expansion in supplies of chips and servers for AI companies, which has completely changed
NON-NEGOTIABLE: The US president’s action ran counter to one of the US’ ‘six assurances’ on not consulting China about arms sales to Taiwan, US lawmakers said US President Donald Trump’s admission that he is discussing arms sales to Taiwan with Chinese President Xi Jinping (習近平) is “alarming and a blatant violation of US policy and the six assurances,” US Representative Ro Khanna said on Tuesday. Trump on Monday said he would decide soon on whether to send more weapons to Taiwan, after Xi warned him not to do so. “I’m talking to him about it. We had a good conversation, and we’ll make a determination pretty soon,” Trump told reporters aboard Air Force One when asked about warnings raised by Beijing during a phone call with Xi over
US and Chinese fighter jets briefly faced off above waters near the Korean Peninsula this week, Yonhap News agency reported, marking a rare confrontation in that area between the two superpowers. About 10 US fighter jets on Wednesday departed an airbase in Pyeongtaek, South Korea, for drills above international waters off South Korea’s western coast, the news outlet cited unidentified military sources as saying. While the US planes did not enter China’s air defense identification zone, Beijing scrambled planes as they neared that region, the report said. “The Chinese People’s Liberation Army organized naval and air forces to monitor and effectively respond
The Central Election Commission has amended election and recall regulations to require elected office candidates to provide proof that they have no Chinese citizenship, a Cabinet report said. The commission on Oct. 29 last year revised the Measures for the Permission of Family-based Residence, Long-term Residence and Settlement of People from the Mainland Area in the Taiwan Area (大陸地區人民在台灣地區依親居留長期居留或定居許可辦法), the Executive Yuan said in a report it submitted to the legislature for review. The revision requires Chinese citizens applying for permanent residency to submit notarial documents showing that they have lost their Chinese household record and have renounced — or have never
