World trade as a share of overall economic activity peaked at 61% in 2008, at the apex of China’s power, when a global financial crisis that started in the U.S. caused a worldwide recession. Trade has since receded to 57% of economic activity, according to World Bank data, still far greater than estimates of 31% on average during the 1970s, 36% during the 1980s or 40% in the 1990s.
