The New Zealand dollar fell after US Federal Reserve Chairman Ben Bernanke said the central bank may taper monthly bond purchases at its next few meetings if it's confident of sustained gains in the economy.
The kiwi dropped to 80.64 US cents from 81.47 cents at 5pm in Wellington yesterday. The trade-weighted index fell to 76.38 from 76.82 yesterday.
The Dollar Index, a measure of the greenback against a basket of currencies, reached its highest in almost three years as investors anticipate the Fed will start unwinding its US$85 billion a month asset purchase programme. Traders are more upbeat about the prospects of the Fed tapering off QE this year as the world's biggest economy shows signs of improvement.
"The US dollar is strengthening and that is weighing heavily on the kiwi dollar," said Michael Johnston, a senior trader at HiFX. "If they scale back bond purchases it is a sign they are more confident about the economic recovery."
Bernanke told Congress the central bank could slow its money printing programme in the next few meetings and is continuing to assess prospects for the job market.
