Why It Matters

South Korea’s energy and semiconductor dependencies mean the Iran war could disrupt global tech supply chains and reshape regional security calculations, forcing policymakers to rethink alliance and diversification strategies.

Key Takeaways

  • Korea hesitates on troop deployment amid US-Hormuz pressure.
  • Domestic politics split between alliance loyalty and China‑Russia‑North Korea tilt.
  • Over 70% of Korean oil imports transit the Strait of Hormuz.
  • Iranian conflict triggers 17% plunge in South Korean stock market.
  • Semiconductor giants face supply risks from energy and helium shortages.

Summary

The Capital Cable episode 132 examined how the escalating Iran‑Israel war is reshaping South Korea’s strategic calculus. Panelists highlighted Seoul’s uneasy position: the United States has asked allies to consider deploying naval forces to the Strait of Hormuz, while South Korea wrestles with a domestic debate between a traditional pro‑U.S. alliance camp and a growing faction favoring greater independence and closer ties to China, Russia, and North Korea.

Experts noted that Korea’s vulnerability stems from its heavy reliance on Middle‑East energy. Roughly 70% of its oil imports travel through Hormuz, and the country imports 84% of the fuel needed for electricity generation. The conflict has already rattled markets, with the KOSPI tumbling 17‑18% in just a few days, underscoring how quickly geopolitical shocks translate into financial volatility.

President Yoon Suk‑yeol’s televised remarks emphasized “strategic flexibility” while reassuring citizens that national security remains robust, reflecting the political tightrope the administration walks. Meanwhile, semiconductor powerhouses Samsung and SK Hynix, which supply 80% of global HBM chips and 70% of DRAM, face production risks not only from oil‑related logistics but also from shortages of critical inputs like helium, essential for chip‑fabrication environments.

The episode concluded that Korea’s exposure threatens both regional stability and global supply chains. Diversifying energy sources, accelerating renewable adoption, and clarifying alliance commitments will be crucial for mitigating the ripple effects of the Iran conflict on the world’s tech and manufacturing sectors.

Original Description

How has the ongoing Iran conflict impacted South Korea? What has the Lee Jae Myung administration done to solve this crisis? How might instability in the Middle East strain the strategic industries and energy flows that underpin South Korea’s economy? Could shifts in U.S. military focus or global force movements influence alliance coordination, extended‑deterrence signals, or even North Korea’s own strategic calculations? And what policy options might South Korea consider as it confronts simultaneous uncertainties in the Middle East and the Indo-Pacific?
Joining Mark Lippert to discuss these issues and more are Victor Cha, Darcie Draudt‑Véjares from the Carnegie Endowment for International Peace, and Jang Ji‑Hyang from the Asan Institute for Policy Studies.
Darcie Draudt‑Véjares is a fellow for Korean Studies in the Asia Program at the Carnegie Endowment for International Peace, where she examines how demographic change, industrial transformation, and geopolitical competition shape national power and state capacity, with South Korea as a leading comparative case. Her work assesses coordination across high‑tech sectors—including semiconductors, batteries, AI, and space—and explores how societal aging and workforce shifts drive strategic and economic policy choices in advanced democracies. She has previously held postdoctoral appointments at Princeton University’s School of Public and International Affairs and the George Washington University Institute for Korean Studies, and has conducted research with the National Bureau of Asian Research, the Council on Foreign Relations, the Korea Economic Institute, and Yonsei University. Dr. Draudt‑Véjares earned her Ph.D. in Political Science from Johns Hopkins University, M.A. in Korean Studies from Yonsei University, and A.B. in Anthropology from Davidson College, and is proficient in Korean after living in Seoul from 2008 to 2013. Her commentary regularly appears in policy outlets analyzing Northeast Asian politics, U.S.–Korea relations, and shifting regional dynamics.
Jang Ji‑Hyang is a Principal Fellow and Director of the Center for Regional Studies at the Asan Institute for Policy Studies, where she leads research on the Middle East and North Africa, comparative politics, political Islam, terrorism, state‑building, and the political economy of the Middle East. She has served as a policy advisor on Middle East issues to South Korea’s Ministry of Foreign Affairs (2012–2018) and continues to advise the Ministries of Industry, Justice, and Defense. Dr. Jang is the author of numerous books and reports, including The Essential Guide to the Middle East (2023) and the co‑edited volume The Arab Spring: Will It Lead to Democratic Transitions?. She has taught Middle East politics, comparative democratization, and political economy at Seoul National University, Ewha Womans University, and Hankuk University of Foreign Studies. She holds a B.A. in Turkish Studies and an M.A. in Political Science from Hankuk University of Foreign Studies and a Ph.D. in Political Science from the University of Texas at Austin. Her research is widely cited in Korean policy circles, especially on how developments in the Middle East influence Korean foreign policy, security, and energy strategy.
