The New Zealand dollar fell to a one month low against the greenback after better-than-expected US employment data stoked bets growth in the world's biggest economy is building momentum.
The New Zealand dollar fell to 81.60 US cents, the lowest since September 10 at 8am, from 81.76 cents at the close of trading in New York and 82.41 cents at 5pm on Friday. The trade weighted index was little changed on 72.93 from 72.89.
Friday's US unemployment rate was significantly better than expected, helping boost equities and risky currencies. The effects were short-lived, with Wall Street's Standard & Poor's index falling 0.3 per cent. The US jobless rate fell to 7.8 per cent last month, the lowest level since January 2009, Labor Department data showed. Payrolls increased by 114,000 workers.
"We saw the kiwi going out reasonably bid in our time zone on Friday but that all changed with the surprise US payrolls data," said Stuart Ive, currency strategist at HiFX. "This led to a broad commodities sell-off and the kiwi and the Aussie coming under pressure.
It's leading some to question whether the Fed's monetary stimulus could drop off."
"We need at least two or three more months of data before the Fed will even consider it," Ive said.
In September, US Federal Reserve Chairman Ben Bernanke announced the central bank would expand its holdings of long-term securities with open-ended purchases of US$40 billion of mortgage debt a month.
