Usually, currencies of countries with higher interest rates tend to rise against those of countries with lower rates. The greenback often becomes the beneficiary of a flight to safety in turbulent times, reflecting its reserve status as the currency of the world's largest economy.
Hamish Pepper, fixed-income and currency strategist at Harbour Asset Management, said the market is looking ahead to a just-scheduled RBA meeting on Thursday – normally the RBA reviews monetary policy on the first Tuesday of each month.
"The overwhelming story is that the RBA will not just deliver a rate cut on Thursday but they will announce a bond-buying programme as well," Pepper said.
Such bond buying is known as quantitative easing - printing money - and that is something RBNZ has ruled out in New Zealand, at least for now.
Pepper said the RBNZ may look at QE when it delivers its next monetary statement scheduled for May 13. "That's probably far enough ahead for the market not to worry about it straight away," he said.
