The Kurdistan Regional Government (KRG) region is a critical oil-producing area. If the KRG declares independence, the Iraqi central government, Turkey, and Iran would likely take military or economic blockade actions, directly threatening oil supplies (especially the operation of the Kirkuk-Ceyhan pipeline). This would cause severe volatility in crude oil prices. While there would be some safe-haven impact on global macro assets (like Gold, DXY), the primary shock would be concentrated in the energy sector.
