The U.S. economy suffered its biggest blow since the Great Depression in the second quarter as the COVID-19 pandemic shattered consumer and business spending, and a nascent recovery is under threat from a resurgence in new cases of coronavirus. The bulk of the deepest contraction in at least 73 years reported by the Commerce Department on Thursday occurred in April when activity almost ground to an abrupt halt after restaurants, bars and factories among others were shuttered in mid-March to slow the spread of coronavirus. More than five years of growth have been wiped out. … Gross domestic product collapsed at a 32.9% annualized rate last quarter, the deepest decline in output since the government started keeping records in 1947. The drop in GDP was more than triple the previous all-time decline of 10% in the second quarter of 1958. The economy contracted at a 5.0% pace in the first quarter. It fell into recession in February.
