At 3.30am Sydney time tomorrow, we will get confirmation the world’s biggest economy has been brought to a dramatic and brutal halt by the coronavirus pandemic.

That’s when the initial jobless claims for last week will be reported by the US Labor Department. It's expected to be the biggest ever rise seen in this key early warning system for the health of the US economy.

Last week, the Labor Department showed the number of Americans filing for unemployment benefits had surged to 281,000, up from 211,000 the week before, as companies across America’s services sector and some of its biggest industries, like airlines, laid off workers.
