Australia's markets are bracing for another big fall on Tuesday when they open after the public holiday.
Sky News Business Editor Ross Greenwood said the fall is expected to be "significant".
"This came after the Dow Jones index of US shares on Friday night was down 981 points – that's 2.8 per cent," he told Sky News Australia.
"Anything more than one per cent is a fairly hefty fall, but something like 2.8 per cent, that's pretty serious when you get into a thousand points.
"On Friday, the ASX 200 was down by almost 1.6 per cent, so it was already falling in advance of the US market falling, but then you go to the futures market which gives you an indication of what will happen when the markets open tomorrow, and they're suggesting another 1.6 per cent fall tomorrow."
