Saudi crude share in South Korea imports falls below 30% for first time in 5 years
Synopsis
For the first time in five years, Saudi Arabia's share of South Korea's crude imports has slipped below 30% — and industry officials warn it could fall further, potentially hitting a record low last seen in 1986. With Houthi rebels threatening Red Sea shipping and the Strait of Hormuz under geopolitical cloud, South Korean refiners are betting on US crude to fill the gap, in a shift that could redraw Asian energy trade flows.
Key Takeaways
Saudi crude accounted for 29.9% of South Korea's total crude imports in January–August 2026 — below 30% for the first time in five years.
The last annual dip below 30% occurred in 2021 , during the COVID-19 pandemic and Middle East tensions.
Industry officials warn Saudi Arabia's share could fall to third place or lower, potentially breaching a record low set in 1986 .
Houthi rebel threats to Red Sea shipping and concerns over the Strait of Hormuz are driving South Korean refiners to diversify.
US crude held a 20.12% share of South Korea's imports over the same period, sustaining above 20% for the first time on a cumulative basis.
Saudi Arabian crude oil accounted for less than 30 per cent of South Korea's total crude imports in the January–August 2026 period, industry data showed on Monday, 5 October, marking the first such dip in five years. The decline reflects a deliberate push by South Korean refiners to diversify supply sources amid mounting geopolitical risks in the Middle East.
Key Developments
According to data from the Korea National Oil Corp. and the Korea Petroleum Association, Saudi crude's share stood at 29.9 per cent of South Korea's total crude imports over the eight-month period, down from 30.91 per cent in the preceding month. Despite the drop, Saudi Arabia remains South Korea's single largest crude supplier.
The last time Saudi Arabia's annual share fell below 30 per cent was in 2021, when global crude supplies were disrupted by heightened Middle Eastern tensions and the COVID-19 pandemic. Industry officials warn that if the current downward trend holds, Saudi Arabia's share could slip to third place or lower by year-end — potentially breaching a record low set as far back as 1986.
Geopolitical Pressures Behind the Shift
The ongoing conflict in the Middle East has disrupted Saudi oil facilities and raised concerns over a possible closure of the Strait of Hormuz, a critical chokepoint for global energy flows. Although Saudi Arabia has rerouted shipments to avoid the Red Sea, those alternative corridors have also come under pressure as Houthi rebels continue to threaten commercial shipping in the region.
This combination of supply disruption risk and shipping vulnerability has accelerated South Korean refiners' move away from a single dominant supplier — a strategy that energy analysts describe as prudent risk management in an increasingly volatile supply landscape.
US Crude Fills the Gap
The primary beneficiary of Saudi Arabia's declining share has been the United States. American crude accounted for 20.12 per cent of South Korea's total imports over the January–August period, remaining above the 20 per cent mark after crossing that threshold on a cumulative basis for the first time during the January–April window. The sustained US share signals a structural — not merely transactional — shift in South Korea's procurement strategy.
Broader Implications for Asian Energy Markets
South Korea is one of Asia's largest crude importers, and its supply-diversification drive carries signal value for the wider region. If other major Asian buyers — particularly Japan and emerging importers in Southeast Asia — adopt similar strategies, the cumulative pressure on Middle Eastern producers could reshape global crude trade flows. This comes amid broader Western and Asian efforts to reduce exposure to geopolitically sensitive supply corridors.
With Houthi activity showing no sign of abating and Middle Eastern tensions remaining elevated, South Korean refiners are expected to maintain, and potentially deepen, their diversification posture through the remainder of the year.
Point of View
A trend that OPEC's pricing power will struggle to reverse through output cuts alone. If South Korea's pattern spreads to Japan and Southeast Asian buyers, the long-term implications for Saudi Aramco's Asia premium — and for the petrodollar architecture — are significant. Energy security has replaced price optimisation as the primary lens for Asian importers, and that calculus is unlikely to reverse even if Middle Eastern tensions ease.

Frequently Asked Questions
Why has Saudi Arabia's share of South Korea's crude imports fallen below 30%?
Saudi Arabia's share dropped to 29.9% in January–August 2026 as South Korean refiners diversified their supply sources amid geopolitical risks, including Houthi rebel attacks on Red Sea shipping and concerns over the Strait of Hormuz. This is the first time the share has fallen below 30% in five years.
When did Saudi Arabia's share last fall below 30% in South Korea's imports?
The last annual dip below 30% was in 2021, when global crude supplies were disrupted by COVID-19 and heightened Middle Eastern tensions. The current drop in 2026 is the first such occurrence since then.
Could Saudi Arabia lose its top supplier position in South Korea?
Industry officials say that if the downward trend continues, Saudi Arabia's share could fall to third place or lower by the end of 2026, potentially setting a new record low below the level last seen in 1986. Saudi Arabia currently remains South Korea's largest single crude supplier.
How much US crude is South Korea now importing?
US crude accounted for 20.12% of South Korea's total crude imports in the January–August 2026 period. This marks the first time US crude has held above 20% on a sustained cumulative basis, after crossing that threshold for the first time in the January–April period.
How are Houthi attacks affecting South Korea's oil supply?
Houthi rebel threats to commercial shipping in the Red Sea have disrupted Saudi Arabia's alternative export routes, adding pressure on supplies already strained by the broader Middle East conflict. This has accelerated South Korean refiners' move to source crude from the United States and other regions outside the Middle East.
