South Korea gasoline and diesel prices ease after government implements price ceiling

Prices for gasoline and diesel at South Korea’s service stations eased on the morning of the 14th, the day after the government introduced a petroleum price ceiling. The nationwide average price for gasoline was 1,851.9 won per liter as of 9 a.m., down 12.2 won from the previous day. Diesel averaged 1,856.1 won per liter, down 16.6 won.

On the first day of the price-ceiling policy, 13th, traffic at a gas station in Gwangju suggested drivers were reacting to the new cap on prices. The photo and report illustrate how the policy shift is playing out on the ground in parts of the country.

In Seoul, the national capital, the price declines continued. The city-wide average for gasoline stood at 1,871.1 won per liter, down 16.5 won from the day before, while diesel dropped 16.2 won to 1,863.1 won per liter.

Domestic gasoline prices had peaked after tensions between the United States and Iran intensified earlier this month, and have subsequently trended downward. Industry observers cautioned that international price movements typically take two to three weeks to filter through to South Korean retail prices, but the petroleum price ceiling has added uncertainty to short-term forecasting.

The data come from OPINET, the oil price information system operated by Korea National Oil Corp., which tracks fuel prices at stations nationwide. The price readings cited reflect the current averages at a specific morning time.

For the United States and other global markets, the moves matter because South Korea is a major importer of crude and a key node in Asian energy supply chains. Shifts in Korean fuel prices can influence regional inflation, manufacturing costs, and logistics in a market that closely links to U.S. supply chains and energy markets. The price-ceiling policy also signals how governments in energy-dependent economies may intervene to temper volatility, with potential spillovers for global markets and consumer costs.
