[DiaryPoint | Reporter Eom Ju-yong] International oil prices plunged as hopes grew that the war with Iran could ease following the U.S. midterm elections. On Nov. 4, Brent crude fell 8.7% to $94.62 a barrel. South Korean drivers may have to wait for the decline to pass through refinery supply prices and retail prices at gas stations before they feel relief at the pump.
After the Democrats’ midterm victory shifted the balance in Congress, markets began to speculate that the Donald Trump administration could face pressure to end the war with Iran. Vice President JD Vance also cited the war as a reason Republicans lost the election. As investors priced in the possibility of de-escalation, concerns about crude supply disruptions and the risk premium tied to a prolonged conflict eased.
The drop does not mean a diplomatic deal has been reached or that oil supplies have immediately returned to normal. The election result and public remarks have changed market expectations about negotiations. If they are not followed by an end to shipping disruptions or changes in production and exports, those expectations could reverse and oil prices could rise again.
It takes time for lower crude prices to reach gas stations
International crude prices affect South Korean gasoline prices through refinery procurement costs, prices for petroleum products and distribution expenses. Industry sources have said that domestic prices typically reflect changes in international oil prices with a lag of about two to three weeks. The size and speed of any decrease can vary depending on exchange rates, refining and transport costs, station inventories and when individual stations adjust prices.
So a sharp drop in oil prices in a single day does not mean gas prices at stations will fall by the same percentage the next day. It is also worth watching whether the decline continues for several days and whether a stronger U.S. dollar raises the cost of importing crude. Gasoline prices are not determined by crude prices alone.
Compare regional averages and nearby stations on Opinet
Opinet, a service run by the Korea National Oil Corporation, publishes gas station prices and domestic oil statistics. Prices collected through card terminals are added to the system six times a day, while prices reported directly by stations are updated as soon as they are entered or revised. Checking averages by region and prices at nearby stations can help drivers distinguish international oil news from changes where they live.
Drivers can track international benchmarks such as Brent, the won–U.S. dollar exchange rate and Opinet’s regional gasoline averages. How much of this drop reaches South Korean pump prices will depend on subsequent oil price movements, exchange rates and price adjustments by refineries and gas stations.
