Asian tech stocks plunge as Middle East war hits supply chains

Asian tech stocks fell as the US-Iran war escalated, disrupting energy and logistics networks across the region.

In Seoul, the Kospi plunged more than 12% on March 4 as Samsung Electronics fell 11.7% and SK Hynix dropped 9.6%.

The conflict has directly hit tech infrastructure: Amazon Web Services said three regional data centers were damaged by drone strikes on March 3, while Nvidia temporarily closed its Dubai office.

Additionally, Baidu and WeRide suspended robotaxi services in Dubai. These disruptions signal growing risks to semiconductor and industrial supply chains as the fighting continues

🧠 Food for thought

Implications, context, and why it matters.

South Korea’s market panic is rooted in more than oil

  • Seoul’s sell-off tracks heavy energy exposure. South Korea imports about 70.7% of its oil from the Middle East, much of it shipped through the threatened Strait of Hormuz 1.
  • Japan faces a similar supply risk. More than 90% of its imported crude oil comes from the Middle East 2.
  • Panic also ties to security concerns. Washington is reportedly weighing a redeployment of missile defense systems such as Terminal High Altitude Area Defense (THAAD) from South Korea to the Middle East for its campaign against Iran 3.
  • That shift could leave a gap in South Korea’s defenses. The country regularly faces ballistic missile threats from North Korea, which adds a military risk premium on top of the economic hit 3.

Global instability could speed up China’s tech self-reliance

  • Mainland Chinese markets have stayed steadier, backed by a long-term push for “technological self-reliance.” China raised it again at the “two sessions” policy meetings, the annual sessions of the country’s top legislature and top political advisory body 4.
  • US tech spending leans toward power-hungry data centers. China has put more money into foundational tools, including advanced semiconductors, to ease chip constraints tied to restricted access to advanced chips 5.
  • To expand AI data centers while moving away from foreign chips, local governments subsidize electricity. Authorities also told state-funded data centers to stop using foreign AI chips in new projects or builds still early in construction 6.
  • Supply chain turmoil linked to the conflict supports Beijing’s approach. It can shelter domestic chipmakers while overseas rivals deal with geopolitical disruption 6.
