Seoul freezes its fuel price caps a fourth time with Brent at $105.90
South Korea held its gasoline price cap at 1,784 won a liter for a fourth straight period, with Brent at $105.90. Industry estimates put refiners' losses at 7 trillion to 8 trillion won, above the 5.6497 trillion won budgeted.
The Investor · Invest desk
Industry estimates put refiners' cumulative losses at 7 trillion to 8 trillion won, against 5.6497 trillion won the government has budgeted. The government estimates each 100-won-per-liter gap between uncapped and capped prices requires about 1.5 trillion won.

| Refiners' cumulative losses, industry estimate, at least | 7 trillion won | up to 8 trillion won | 22 |
| Budget for refiner losses | 5.6497 trillion won | 12 | |
| Per 100-won gap, about | 1.5 trillion won | 13 |
What happened
- Diesel stays capped at 1,773 won a liter and kerosene at 1,380 won for the four weeks starting Saturday, according to the Ministry of Trade, Industry and Resources.
- The ceilings have held for 16 weeks since June 27, after a cut to these levels on June 26.
- Seoul introduced the caps in mid-March to stabilize domestic fuel prices after the US-Iran war disrupted supply chains.
Why it matters
- What it costs cost Refiners are owed money they cannot yet size: compensation is set after a review of their costs and a reasonable profit margin, so a loss estimate is not a payout.
- Who's exposed exposure Heating season adds volume risk: the EIA projects eastern US diesel and heating oil inventories 20% to 30% below the five-year average, a setup that could lift international product prices.
- Who has to decide decision Ending the cap means letting capped prices move toward uncapped levels in a heating season, a call the ministry has left open by saying it will adjust the measures as necessary.
Each week the ceiling holds adds to a bill the budget pays. Public funds cover the losses that arise when refiners cannot pass higher costs on to sale prices [18], and the ministry's working figure, in data obtained by People Power Party lawmaker Cho Ji-yeon, is about 1.5 trillion won of compensation for every 100-won-per-liter gap between the uncapped and the capped price [13]. The government has set aside 5.6497 trillion won against that [12], about 26% of it in next year's budget proposal [c9, d5]. Industry estimates put refiners' cumulative losses at 7 trillion to 8 trillion won [22]. That leaves 1.35 trillion to 2.35 trillion won uncovered, or 24% to 42% on top of the budgeted sum [d1, d2].
For operators the question is which input. Gas stations buy at a supply price that is flat by order, so for the three capped fuels the Iran-war cost has gone into the fiscal line and not into the price. Where it shows up in prices is outside the list. The ministry said Brent at $105.90 on Oct. 15 was "pushing up the prices of petrochemical products" [c4, c5], and the government said petroleum prices rose 14.8% in September from a year earlier even with the cap in place [10]. The articles do not include a petrochemical price series or any measure of what operators pay, so the pass-through is not sized here.
We think the freeze is extended again at the next review. The ministry framed it as easing "upward pressure on consumer prices" [6], and a price rise would land first on households the government says are already carrying the burden [10].
The case against sits in Brent itself. At $105.90 it is 90 cents above the $105 fourth-quarter average the US Energy Information Administration forecast this month [c13, d4], and that forecast was raised by $14 in a month, from an implied $91 [c13, d3]. A forecast that moved $14 one way can move back, and Brent near $91 would shrink the shortfall above. Against a fall, Iran has continued attacks on vessels passing through the Strait of Hormuz, and Yemen's Houthi rebels have struck Saudi airports and oil facilities [15]. We would be wrong on the extension if Brent slid toward $91 before the next review, or if the budget proposal were cut.
Son Yang-hoon, an economics professor at Incheon National University, said the fiscal burden is mounting because the cap has stayed in place too long. "It should be halted as soon as possible and prices should be set properly," he said [16].
What to watch
- Brent against the EIA's $105 fourth-quarter forecast and the implied $91 of a month earlier, ahead of the next four-week review.
- Whether the 1.4497 trillion won in next year's budget proposal survives, and whether a further request follows for the 1.35 trillion to 2.35 trillion won gap.
- Any petrochemical price series from the ministry or industry, which would show how much of Brent's rise reaches operators outside the capped fuels.
