The New Zealand dollar rose as the greenback weakened on trader bets that Federal Reserve Chairman Ben Bernanke on Wednesday may say he is still cautious about the pace of recovery in the world's largest economy.
The kiwi rose to 81.72 US cents from 81.20 cents at the 5pm market close yesterday. The trade-weighted index gained to 76.98 from 76.65 yesterday.
The Dollar Index, a measure of the greenback against a basket of currencies, pulled back after climbing to near a three-year high on Friday as investor confidence about the US economic recovery ebbed. Bernanke's testimony in front of a House of Representatives committee on Wednesday may be more cautious than some other central bank officials who support unwinding quantitative easing.
"The market is a little bit concerned that maybe he is going to remain cautious," said Sam Tuck, senior manager FX at ANZ New Zealand. "He's renowned for being one of the more cautious members."
Tuck expects the local currency to trade in a range of 81.20 US cents to 82.20 cents today.
