Can East Asian economies absorb a Gulf supply shock if the Strait of Hormuz closes?
Latest on East Asia
- What is East Asia's role in the Iran conflict?
- East Asia is not a direct combatant but is among the most economically exposed regions. South Korea and Japan are the world's largest Gulf oil and LNG importers; the conflict has already triggered record stock-market falls and surging shipping costs for tankers serving the region.Source: Lowdown
- How did East Asian stock markets react to the Iran war?
- South Korea's KOSPI fell 12% in its worst single session on record and Japan's Nikkei dropped 3.9% as the Iran-Israel-US conflict escalated, reflecting fears over Gulf oil supply disruption.Source: Lowdown
- How much have tanker rates risen due to the Iran war?
- Charter rates for tankers on Gulf routes quadrupled to $800,000 per day, with war-risk premiums on very large crude carriers running between $3.6 million and $6 million per voyage, hitting East Asian importers hardest.Source: Lowdown
- Is the Strait of Hormuz still open to East Asian tankers?
- The Strait of Hormuz has not been closed, but the Iran conflict has sharply raised war-risk insurance and charter costs for tankers serving East Asian ports, with Iran also demonstrating naval reach as far as Sri Lanka.Source: Lowdown
- How does East Asia's energy dependence compare to Europe's?
- East Asia accounts for over half of global LNG demand and imports the majority of its crude oil from the Gulf, a significantly higher dependence than Europe, which has diversified supply since 2022.Source: Lowdown
Background
East Asia is a politically diverse macro-region spanning China, Japan, South Korea, Taiwan, and adjacent states. It accounts for more than half of global LNG demand and a large share of crude oil imports, most transiting the Strait of Hormuz. The region has no unified security architecture and states hold divergent stances toward Iran and the Gulf.
East Asia emerged as one of the most economically exposed regions to the Iran-Israel-US conflict. South Korea's KOSPI fell 12% in its worst single session on record; Japan's Nikkei dropped 3.9% as markets priced in a supply shock, both countries ranking among the world's largest importers of Gulf oil and LNG. War-risk insurance has since driven tanker charter rates to $800,000 per day, compressing margins for every importer dependent on Persian Gulf shipping lanes.
The sinking of the Iranian Navy frigate IRIS Dena near Sri Lanka showed the conflict projecting naval force deep into the Indian Ocean, directly on the tanker route to East Asian ports. The region faces a structural dilemma: heavy energy dependence on the Gulf with no capacity to influence the conflict or protect its own supply lines.
