Korea’s pump prices fall for a 17th week, but the oil-price lag matters
Fuel prices at gas stations across Korea continued to fall for a 17th consecutive week. Yonhap and business outlets cited Korea National Oil Corporation’s Opinet data showing that in the second week of September the national average gasoline price was 1,859.1 won per liter and diesel averaged 1,844.0 won. The figures suggest slightly lower pressure on drivers, but the same reports noted a sharp rise in global oil prices, making the next few weeks of pass-through important.
Key summary
- The national average gasoline price in the second week of September was 1,859.1 won per liter, down 1.1 won from the previous week.
- The average diesel price was 1,844.0 won per liter, down 0.5 won from the previous week.
- Seoul’s average gasoline price was 1,905.3 won, while Daegu stood at 1,832.1 won, showing persistent regional gaps.
- Because global oil-price changes usually feed into Korean pump prices after two to three weeks, the current price alone does not settle the trend.
Confirmed facts
- Yonhap reported, based on Opinet data, that gas-station fuel prices fell for a 17th week.
- Maeil Business Market and Etoday also highlighted the 1,859-won gasoline average, higher global oil prices and the domestic pass-through lag.
- Dubai crude as well as international gasoline and diesel prices were reported to have risen from the previous week.
- Whether the government maintains its petroleum price-cap policy and how the next notice is set remain variables for domestic prices.
How to read it as a household-cost issue
Lower pump prices are an immediately felt cost-of-living issue, but the national average is not the only figure consumers should watch. Even in the same week, prices can differ widely between Seoul and Daegu, and between discount stations and major-brand stations. When global oil prices rise, domestic prices may respond later, so the more practical question is not simply “was fuel cheaper this week,” but whether the stations along your normal route stay lower two to three weeks from now.
| Indicator | Latest figure | What to check |
|---|---|---|
| Gasoline average | 1,859.1 won per liter | Whether nearby stations are above the national average |
| Diesel average | 1,844.0 won per liter | Whether long-distance driving costs start rising |
| Global oil price | Dubai crude rose week on week | Potential domestic rebound after two to three weeks |
What to watch next
- Check whether the next petroleum price-cap notice later in September keeps the same level.
- Watch how quickly the rise in global oil prices appears in Korean gasoline and diesel prices.
- As Chuseok travel approaches, regional and route-by-route price differences may become more noticeable.
- For drivers, checking Opinet or nearby station prices is more useful than relying only on national averages.
