The New Zealand dollar is little changed ahead of a Federal Reserve meeting this week which is expected to signal the outlook for monetary stimulus in the world's largest economy.
The kiwi recently traded at 80.75 US cents, from 80.84 cents at the close of New York trading and 80.79 cents at the 5pm market close in Wellington on Friday. The trade-weighted index weakened to 75.97 from 76.03 on Friday.
Federal Reserve chairman Ben Bernanke is expected to signal when the US central bank plans to start tapering its US$85 billion a month quantitative easing programme following a two-day meeting this week. The monetary stimulus programme has debased the greenback, and increased the lure of currencies such as the New Zealand dollar.
"The market is going to be a bit volatile" ahead of the Fed comments, said Martin Rudings, senior advisor at OM Financial. "What he says about the tapering of QE is going to be very important in how global yields move."
Traders are speculating Bernanke may lower his targeted unemployment rate necessary to trigger interest rate rises to 6 per cent from 6.5 per cent, Rudings said.
