Last crisis (Spanish flu) caused a 5% decrease in global GDP and that was without widespread shutdowns and an already depressed GDP from the first world war.

I think realistically the drop in demand, the onslaught of bankruptcies, the stopping of lending and the depletion of consumers' and corporate cash savings will lead to a prolonged recession of at least 5% GDP decrease.

On the upside, climate change is now within bounds for the coming years.
