South Korea Caps Fuel Exports to Safeguard Supply

Why It Matters

The caps safeguard South Korea’s fuel security and curb export‑driven price spikes, influencing regional product availability and refining margins across the Asia‑Pacific market.

Key Takeaways

• Export caps limit shipments to 2025 levels.
• Domestic price caps set at 1,724 won/litre gasoline.
• Spot gasoline supply expected to shrink sharply.
• Refiners may shift to fuel oil and jet fuel production.
• Korea may compensate refiners for export losses.

Pulse Analysis

South Korea’s abrupt export caps on gasoline, diesel, kerosene and soon naphtha reflect a strategic response to supply‑chain volatility in the Middle East, especially the Strait of Hormuz bottleneck. By anchoring export volumes to 2025 levels and imposing wholesale price ceilings—1,724 won per litre for gasoline, 1,713 for diesel, and 1,320 for kerosene—the Ministry of Trade, Industry and Energy seeks to preserve domestic inventories while deterring refiners from chasing higher overseas prices. The policy also mandates a 90 % domestic supply floor for March‑April, signaling a firm commitment to internal market stability.

Market participants anticipate a pronounced contraction in spot gasoline availability, even as term contracts continue largely unchanged. Negative gasoline crack spreads against Dubai crude have already squeezed margins, prompting refiners to prioritize higher‑margin fuel oil and jet‑fuel yields over gasoline output. This shift could tighten the regional jet‑fuel market, where Korean exporters are already scaling back due to maintenance at the Daesan refinery. The combined effect of export caps and margin pressures is likely to reduce spot volumes, prompting buyers to source from alternative hubs or secure longer‑term contracts.

The ripple effects extend beyond Korea’s borders. Import‑dependent nations such as Australia stand to gain modest relief as Korean term supplies become more predictable, while the broader Asia‑Pacific clean‑product market remains tight due to parallel export curbs in China and Taiwan. Simultaneously, South Korea is diversifying its crude feedstock, leveraging strategic petroleum reserve releases, U.S. sanctions waivers on Russian oil, and exploring unconventional sources like Libyan grades. These supply‑side adjustments, coupled with the temporary export caps, will be reassessed after 14 days, shaping the region’s fuel‑security outlook for the coming months.
