South Korea is highly dependent on oil imports relative to GDP, and its stocks and won have been hit by the September 14 attacks on Saudi refineries and an ongoing trade dispute with Japan.

Oil-driven pressure on the won raises Korean feed import costs in local terms, and energy price swings feed through to biofuel and freight economics.
