Oil tops $100 as Korea imposes nationwide fuel price cap
International oil prices surged above $100 per barrel for the first time in three years and seven months, as markets reacted to heightened tensions in the Middle East. Brent crude for May delivery settled at $100.46 per barrel, marking a breach of the $100 level not seen since August 2022.
Back home in South Korea, fuel prices began to soften after the government introduced a petroleum price ceiling on the 13th. The Korea National Oil Corporation’s OPINET price-tracking system showed the nationwide average price of regular gasoline at 1,883.79 won per liter as of 10 a.m., down 14.99 won from the previous day. Diesel fell by 21.08 won to 1,897.89 won per liter.
In the capital, Seoul, the price trajectory also leaned downward. The average gasoline price in Seoul was 1,906.40 won per liter, down 20.66 won, while diesel dropped more sharply, to 1,905.53 won per liter, a 30.64 won decline. The declines reflect market expectations of government intervention to cap consumer costs amid volatile crude markets.
The government’s price-ceiling policy came into force at midnight on the 13th, setting a cap on wholesale prices for key fuels: 1,724 won per liter for regular gasoline, 1,713 won for diesel, and 1,320 won for kerosene used for heating and other domestic purposes. Officials described this as a move to stabilize domestic fuel costs as international prices fluctuated.

Under the policy, the ceiling will be reviewed and potentially revised every two weeks, taking into account ongoing developments in the Middle East and broader oil-market trends. The measure marks a rare use of direct price controls in Korea, the first such action since the liberalization of oil prices in 1997.
The price surge in global markets has been linked to Iran-related tensions, including the election of a new Iranian leadership figure described in the report as a “new supreme leader,” who pledged a tougher stance toward the United States and Israel. The same day, Brent crude futures rose above $100 for the first time since mid-2022, underscoring how closely domestic prices track international sentiment and supply concerns.
Why this matters to U.S. readers: South Korea’s move highlights how global oil volatility feeds into consumer electricity and fuel costs on a major importer’s doorstep, with potential ripple effects on inflation, manufacturing costs, and policy choices in the United States. The price-ceiling approach contrasts with U.S. market-based pricing and can influence Korean supply chains, automakers, airlines, and heating markets. As Asia absorbs more energy risks from the Middle East, U.S. policymakers and markets monitor how such interventions could inform or interact with global oil prices, sanctions considerations, and energy-security strategies.
