Double Crisis of Cost and Delivery: 5 Shocks the Iran War-Driven 80% Freight Rate Surge Poses for Hyundai, Samsung & LG's Export Operations
Following the U.S.-Israeli strikes on Iran, the risk of a Strait of Hormuz blockade has become real, with warnings that maritime freight rates could surge by up to 80%. Korea's key export industries — automobiles, home appliances, and semiconductors — now face a double crisis of rising costs and delivery delays.
Why you need to read this now: Five days into the war, gasoline in Seoul has crossed ₩1,800 per liter — and this is not just a gas station problem. Ships and goods exported by Hyundai, Samsung, and LG are beginning to stall.
TL;DR
- Rerouting around the Hormuz Strait could push freight rates up by as much as 80%, extending shipping routes by 10–14 days
- Hyundai, Samsung, and LG face surging logistics costs and potential shipment delays on Middle East and European exports
- Semiconductors and display components face a separate risk from soaring air freight rates
- 65% of Korea's imported crude oil passes through the Hormuz Strait → a compound energy and logistics crisis
- Uncertainty grows over Hyundai's Saudi Arabian plant HMMME, planned to begin operations this year
The Facts: What Happened
Immediately after the U.S.-Israeli joint strikes on Iran began on March 3, 2026 (local time), Iran publicly raised the prospect of blocking the Strait of Hormuz, through which approximately 20% of the world's crude oil shipments pass. Global shipping companies immediately began reviewing expanded rerouting via the Red Sea and Suez Canal, and started imposing Emergency Conflict Surcharges (ECS) of several thousand dollars per container.
The Korea International Trade Association and industry experts have analyzed that full use of alternative routes could push maritime freight rates 50–80% higher than before, with shipping times increasing by 3–5 days. If major carriers like Maersk expand Cape of Good Hope rerouting, shipping routes could be extended by 10–14 days.
Why Korean Manufacturing Is Especially Vulnerable
① Home Appliances: Structural Dependence on Sea Freight
Large home appliances such as TVs, refrigerators, and washing machines are virtually impossible to ship by air, making them over 90% dependent on sea containers. Samsung Electronics and LG Electronics export almost all large appliances bound for the Middle East and Europe by sea. Margin pressure is expected to intensify, particularly for TVs, which carry a high logistics cost ratio.
② Automobiles: Delivery Delays and Local Sales Disruption
Hyundai Motor Group is concerned about rapidly rising logistics costs for complete vehicle and parts exports to the Middle East. In particular, Hyundai is building HMMME (50,000 units per year), its first regional production base in Saudi Arabia, targeting Q4 this year — and the spread of regional conflict could disrupt local production and sales strategies.
③ Semiconductors & Displays: Separate Risk from Soaring Air Freight
Semiconductors and high-value display components are primarily shipped by air, but Middle East airspace closures and rerouting are driving air freight rates sharply higher as well. This is a separate supply chain shock from the maritime risk.
④ Double Energy Shock
About 65% of Korea's imported crude oil passes through the Strait of Hormuz. Energy supply instability is adding upward pressure to overall manufacturing costs while also threatening to drive up wholesale electricity prices. Public and private strategic oil reserves stand at roughly seven months' worth, but if the situation drags on, LNG supplies could also come under threat.
Context: A Déjà Vu of the 2024–2025 Red Sea Crisis
This shock bears similarities to the 2024 Red Sea crisis, but is far larger in scale and impact. At that time, container freight rates rose and fell over several months — but this time, the direct military factor of the Iran War creates far greater uncertainty.
As the Red Sea situation stabilized in the first half of 2025, Samsung and LG had briefly enjoyed some relief from lower logistics costs. The current crisis could reverse that in an instant.
Outlook: How Long Could This Last?
| Scenario | Description | Freight Impact |
|---|---|---|
| Short-term blockade threat → Negotiation | Iran uses blockade only as a bargaining chip | +20–30%, stabilizes within weeks |
| Partial blockade | Iran inspects ships, threatens civilian vessels | +50–60%, persists for months |
| Full blockade & prolonged conflict | Effective closure of the Hormuz Strait | +80%+, global logistics paralysis |
JP Morgan has previously warned that a full blockade could push international oil prices to $120–$130 per barrel.
