The escalation of military conflict involving the United States, Israel and Iran has sent shockwaves well beyond the Middle East. For Korea — one of Asia’s most trade-dependent, energy-hungry economies — the implications may be immediate, structural and far-reaching. From crude oil prices to export controls, Korea faces the prospect of a new era of heightened volatility.
One source of vulnerability lies in a basic structural reality: The country imports more than 80 percent of the energy it consumes, with around 70 percent of its crude oil and 20 percent of its liquified natural gas (LNG) imports sourced from the Middle East. When the Strait of Hormuz faces disruption, Korea — the world’s fourth-largest oil importer — is likely to feel it acutely.
The initial market reaction has been swift and pronounced. Korea’s leading stock index lost more than 12 percent in early March, with trading temporarily suspended, while the won weakened against the dollar as energy market fears rippled through financial markets. For refiners, petrochemical producers and heavy manufacturers, that kind of sudden price movement can translate into margin compression and cost pressures across the supply chain.
Policymakers in Seoul appear to be moving quickly. A range of emergency measures are reportedly already underway, from fuel price interventions to the release of strategic oil reserves, as the government moves to cushion the immediate economic impact. The conflict may also be accelerating longer-term diversification away from Gulf supply. While Korea has been expanding LNG sourcing from the United States, Australia and Qatar, the current crisis creates a compelling impetus to extend that diversification to new relationships and supply corridors. Energy security and the clean energy transition are increasingly aligned in this context.
Energy is only part of the story. Korea’s deep reliance on imported commodities — from the raw materials for its steel and petrochemical industries to food imports — means that any sustained disruption to Gulf supply chains could have a multiplier effect through the broader economy.
Higher commodity prices tend to squeeze corporate margins and erode household purchasing power. For Korea’s export-oriented manufacturers, rising input costs are particularly painful at a time when global demand is softening and competition is intensifying. Areas such as steel, shipbuilding and the automotive industry — cornerstones of the Korean economy — are directly exposed to energy and raw material price swings in ways that are difficult to hedge over the short term.
The Bank of Korea, like its regional peers, has been cautiously navigating an easing cycle. A sustained commodity price shock could force a pause or even a reversal of that trajectory, tightening financial conditions at precisely the moment the economy needs support.
As the Middle East conflict shows no signs of ending, countries are increasingly likely to align their trade and export control policies with their geopolitical positioning, raising the prospect of a more fragmented trade environment, so access to end markets, shipping routes and critical inputs can no longer be taken for granted.
For Korea — a major exporter of semiconductors, automobiles, steel and chemicals — this creates a new layer of compliance complexity. The risk of selective export restrictions, informal boycotts and tighter customs scrutiny is rising, not just from conflict-adjacent parties but also from major trade partners seeking to limit their own exposure to secondary sanctions or political blowback. Controls on dual-use goods will likely tighten further across multiple jurisdictions, adding compliance burdens for exporters and logistics providers. Authorities may raise expectations around transparency, including more stringent requirements to identify who ultimately owns or controls business entities, requiring greater investment in legal and compliance infrastructure.
Korea's semiconductor industry could face a more immediate supply chain threat as well. The Middle East is a significant source of critical industrial inputs used in chip manufacturing, and any sustained disruption to production or transit in the region could tighten global supplies, raise input costs and constrain output for one of the country's most strategically important export industries.
