Market Reaction to Potential U.S. Ban on Chinese Data‑Center Components
Reuters reported that the Trump administration is drafting rules to prohibit U.S. imports of new Chinese data‑center components, specifically optical transceivers used to move data through fiber‑optic cables inside data centres. The Federal Communications Commission is preparing the rule, intends to publish the measure within the current year, and may still modify or shelve it. The proposed restrictions are justified as a means to reduce security risks associated with AI infrastructure, including data theft, malware and service disruptions.
Investors responded swiftly, driving a sharp sell‑off in Chinese AI optical hardware stocks. Zhongji Innolight (stock codes SZ:300308 and HK:3308) fell approximately 10% in both Shenzhen and Hong Kong trading sessions, marking the largest single‑day decline among the sector. Eoptolink Technology (SZ:300502) declined more than 7%, while Suzhou TFC Optical Communication Co (SZ:300394) slipped 3.5%.
The article notes that market participants are assessing the potential impact on exporters heavily exposed to the U.S. market, reflecting concerns that the ban could curtail demand for Chinese‑made optical components in American data‑center deployments.
