SEOUL – South Korea's nationwide average fuel prices continued their sharp descent for the second consecutive day following the implementation of the government’s emergency "Oil Price Cap" system. As of the morning of March 14, 2026, the double-digit drop in retail prices has provided a brief sigh of relief for consumers, even as international crude markets remain turbulent due to geopolitical instability.

Accelerated Decline Under the New Policy
According to Opinet, the oil price information service operated by the Korea National Oil Corporation (KNOC), the average price of gasoline at pumps nationwide stood at 1,851.9 KRW per liter as of 9:00 AM, marking a 12.2 KRW decrease from the previous day. Diesel prices saw an even more significant plunge, falling 16.6 KRW to settle at 1,856.1 KRW per liter.

This trend is particularly noteworthy because it reflects the direct impact of the government’s intervention. Under the newly enforced Oil Price Cap, the maximum supply price for diesel was set lower than that of gasoline, forcing a faster downward adjustment for diesel. Consequently, the price gap between the two fuels—which had widened to over 20 KRW recently—is rapidly narrowing.

In Seoul, traditionally the most expensive region in the country, the downward trend was even more pronounced. Gasoline prices in the capital fell by 16.5 KRW to 1,871.1 KRW per liter, while diesel dropped by 16.2 KRW to 1,863.1 KRW.

The Geopolitical Context: War and Strategic Reserves
The current volatility stems from the outbreak of conflict between the United States and Iran earlier this month. Local pump prices peaked on March 10 before the government stepped in with the price cap.

While domestic prices are currently falling due to policy pressure, the international landscape tells a more complex story. This week, global oil prices faced upward pressure following news of the continued blockade of the Strait of Hormuz and a full-scale production cut by major Middle Eastern oil producers.

However, the rally was somewhat stifled by the International Energy Agency’s (IEA) agreement to release strategic petroleum reserves (SPR) to stabilize the global market. Despite this, the benchmark Dubai crude rose by $34.6 to $123.5 per barrel last week. International gasoline prices climbed by $25.3 to $126.3, while international automotive diesel surged by $37.5 to $176.5.

Uncertainty Looms for the Industry
The discrepancy between rising international costs and falling domestic prices is creating a unique challenge for the refining industry. Typically, changes in international oil prices take about two to three weeks to be reflected at local gas stations. However, the immediate enforcement of the price cap has disrupted this traditional cycle.

"While international prices are on an upward trajectory, the domestic market is being artificially suppressed by the price cap," said an official from the refining industry. "Because the current pricing is dictated by policy rather than market flow, it is extremely difficult to forecast price trends for the coming weeks."

As the nation watches the second week of this emergency measure, the focus remains on whether the government can sustain these lower prices if international crude remains above $120 per barrel, or if the pressure on refiners will eventually lead to supply bottlenecks.
