SEOUL — South Korea’s domestic fuel prices maintained a downward trend over the first weekend since the implementation of the "Petroleum Maximum Price System," although the pace of the decline has significantly slowed. As the nation grapples with the economic aftershocks of the conflict between the United States and Iran, the new price cap serves as a critical buffer for weary consumers.

Domestic Price Trends: A Slowing Descent
According to Opinet, the Korea National Oil Corporation's fuel price information service, the national average price for gasoline stood at 1,842.1 won per liter as of 9:00 AM on Sunday, March 15. This represents a modest decrease of 3.2 won from the previous day. Diesel prices followed a similar trajectory, falling by 4.4 won to settle at 1,843.6 won per liter.

In the capital, Seoul, where living costs typically outpace the national average, the decline was also evident. The average gasoline price in Seoul dropped to 1,865.2 won per liter (down 2.9 won), while diesel saw a more substantial dip of 16.2 won, reaching 1,854.6 won per liter.

This cooling period comes after a volatile week. Domestic pump prices reached a historic peak on March 10, triggered by the immediate fallout of the U.S.-Iran war. While the current price cap has successfully halted the vertical climb, industry experts note that the "drop" is becoming a "drip," as the magnitude of daily decreases continues to shrink.

International Volatility: The Hormuz Factor
Despite the slight relief at home, the international energy market remains a tinderbox. Crude oil prices saw an upward surge last week, fueled by the ongoing blockade of the Strait of Hormuz and reports of aggressive production cuts from major Middle Eastern oil producers.

Dubai crude, South Korea’s primary benchmark, surged to $123.5 per barrel, a staggering increase of $34.6 from the prior week. The impact was felt across all refined products:

-International Gasoline: Rose by $25.3 to $126.3.
-International Diesel: Jumped by $37.5 to $176.5.

The only factor preventing a total price explosion was the coordinated effort by the International Energy Agency (IEA). Member nations agreed on a strategic petroleum reserve release, which managed to cap the potential ceiling of the price spike.

The Two-Week Lag: A Storm on the Horizon?
The primary concern for South Korean policymakers and consumers is the "time lag" inherent in the oil supply chain. Changes in international oil prices typically take two to three weeks to manifest at local gas stations.

While the "Petroleum Maximum Price System" is currently shielding drivers from the worst of the volatility, the recent $30+ jump in Dubai crude is expected to exert immense upward pressure on domestic prices by early April. If the Middle East tensions do not subside, the government may face a difficult choice between subsidizing the gap or allowing the price cap to adjust upward to reflect the global reality.

Public Reaction and Market Outlook
At a local gas station in downtown Seoul on Sunday, citizens were seen taking advantage of the weekend lull to fill their tanks. "Every won counts these days," said one commuter. "The news says prices are down, but it still feels twice as expensive as last year. We are just hoping the war ends soon so things can go back to normal."

As the second week of the price cap begins, the Ministry of Economy and Finance is expected to monitor the situation closely. The focus will remain on whether the strategic reserves can stabilize the market long enough for the current geopolitical friction to ease.
