"We probably should expect more downside in US stocks, which should eventually weigh on the kiwi and Aussie dollars."
Longer-term, the US response to combatting covid-19 – "you would politely call it a confused approach" – is likely to prolong the economic impact on the world. A number of states are still not in lockdown.
"There's no way there's not going to be a massive plunge in demand in the US for the world's products," Gilligan said.
The virus continued its grim progress in the US with its cases of infection now numbering 336,830, outstripping the totals in Spain and Italy combined, the two countries suffering the worst impact in Europe.
New Zealand cases rose by 67 to 1,106, or 229 cases per million people compared with 1,108 per million in the US.
New Zealand still has just a single death from the virus while the US has 9,618 and White House officials estimate there will be between 100,000 and 240,000 deaths.
