But equities traders in New York "are living in a dream world. They think the stimulus is going to save them from the virus," he said.
Early today, the US became the country with the largest number of coronavirus cases, overtaking China, where the virus originated, and Italy, which has been devastated by the disease.
The US now has 85,594 people counted as infected, up from 68,211 yesterday, and 1,300 of its citizens have died. China's number of reported infected stands at 81,340 and Italy's at 80,589 with deaths of 3,292 and 8,215 respectively.
New Zealand's cases jumped by 85 to 368 and nobody has died of it here yet. That's 76 cases per million people compared with the US rate at 259 per million and Italy at 1,333.
Rudings said reports that US unemployment claims jumped to a record 3.3 million last week, from 281,000 the previous week and easily ahead of the previous record of 695,000 set in October 1982, only served to fuel market expectations that the Federal Reserve would pump more money into the economy.
"They've already fired a bazooka-load at it," Rudings said, adding that expectations that the US economy can revert to normal in a couple of weeks are unrealistic.
"It's a little bit too early in the virus scenario to start talking about the other end of the tunnel."
