The virus is proving an expensive house guest as it hits corporate revenue, profit margins, and balance sheets. As El-Erian points out, the three major components of global gross domestic product—consumption, trade, and investment—are taking a hit to some degree from the spread of the virus. Even before the age of the new coronavirus dawned, global trade had fallen last year for the first time since 2009 because of a tariff war between the U.S. and China and a manufacturing recession. Now the world economy is on track for its weakest year since the financial crisis as the new coronavirus takes its toll, according to analysts at Bank of America Corp. Global growth will slip to 2.8%, from a previous estimate of 3.1%, and the Chinese economy will advance at 5.2%, which would be the worst performance since 1990.
