US stock futures extended losses on Friday after President Donald Trump said he and his wife had tested positive for the coronavirus, weeks ahead of elections.
Futures for the S&P 500 EScv1 slid 1.21 per cent by early afternoon in Asia, while Treasury yields also fell.
The US dollar rose, particularly against the British pound, the Australian and New Zealand dollars in a sign of risk aversion.
Trump earlier said on Twitter that he and his wife had been tested for coronavirus after Hope Hicks, a senior advisor who recently traveled with the president, tested positive.
He later tweeted he and the first lady had tested positive: “We will begin our quarantine and recovery process immediately,” he said.
Trump’s positive could cause a new wave of market volatility as investors brace for the hotly-contested presidential election in November.
“It has the potential to reduce Trump’s campaigning ability. He’s got a lot on and it’s an interruption,” said Sean Callow, currency strategist at Westpac in Sydney.
“It also hurts him as far as the whole narrative that it’s really not much to worry about - it puts the COVID crisis itself back front and centre.”
