Some economists suggest that China's economy may contract for the first time since the 1970s. Caixin's purchasing managers index for the services sector of China's economy fell to 26.5 in February 2020, the lowest figure recorded since the survey's advent in 2005,[30] and car sales dropped 86% in China in February.[31] As the coronavirus spreads around the world, the stock markets have experienced their worst crash since 1987.[31]
