  • Trends in global economic activities directly affect the volume of merchandise trade and worldwide movement of freight. The growing reliance on global supply chains means the effect of an economic downturn is not limited to exporting and importing nations. Other nations that provide freight and port services to transport traded goods are also affected.

  • Between 2001 and 2008, the U.S. share of world GDP declined as the share of emerging and developing economies grew. Many other factors contributed to this trend, including foreign currency exchange rates, business cycles, balance of payments, and central banks policies- all of which affect the value of internationally traded goods.
