A record-breaking heatwave in South Korea has caused diverse economic and logistical challenges. In Seoul, the extreme temperatures have strained small sewing factories where workers face high temperatures and increased occupational health risks, while reduced orders for clothing have lowered factory incomes. Traditional markets have also seen decreased foot traffic and rising electricity costs, though cafes and ice cream shops have reported increased sales.

The heatwave has further escalated into a broader food security and inflation issue. Significant agricultural and aquaculture losses have been reported, including nearly one million livestock deaths—primarily poultry—and over 860,000 fish deaths due to rising sea temperatures. Consequently, retail prices for certain vegetables, such as spinach, have surged by over 150%. In response, the South Korean government has introduced measures to stabilize food prices, such as increasing poultry imports and launching seafood discount campaigns.
