  5. Retail – Increased import costs led to higher prices for consumer goods.

  6. Energy – Some energy exports faced reduced competitiveness due to tariffs.

  7. Small Businesses – Suffered from higher import costs and supply chain disruptions.

  8. Global Investors – Market volatility increased due to trade tensions.

  9. Supply Chain Realignment – Companies moved sourcing to alternative countries like Vietnam, India, and Mexico.

Global Response and Trade Wars
