Probably not that simple. If we had a planned and publicly notified and unified worldwide lockdown and curfew for 20 or 30 days, including the stock markets - the recovery would have been sooner. People and businesses can take that hit. But with segregated efforts, some doing serious lockdowns and some not so serious lockdowns, where countries are interdependent, the timeline is unknown and hence the impact is unknown. Businesses might be able to stay healthy may be 15 days more. But beyond that is a strong possibility, and hence the economic impact is going to be much larger and uncertain.
