The global economic downturn, the worst economic contraction since the Great Depression, dragged down all modes of freight transport. World air cargo traffic dropped 13% over the two years ending in 2009. Traffic jumped 19.4% in 2010 and gained a further 0.8% in 2011 as global businesses replenished their inventories. The net result of these developments is a world air cargo traffic growth rate of only 2.6% for the span of years between 2003 and 2013. The growth rate since 2008 is only 1.7%. Containership traffic slowed to a similar pace during this timeframe.
