The New Zealand dollar dropped to a seven-month low after the Federal Reserve raised its expectation for the level of interest rates by the end of next year, boosting the lure of the greenback.
The kiwi touched 80.73 US cents, and was trading at 80.96 cents at 8am in Wellington, from 81.84 cents at 5pm yesterday. The trade-weighted index fell to 78.09 from 78.50 yesterday.
The US dollar index, which measures the greenback against a basket of currencies, rose to a 14-month high after the Federal Reserve Open Market Committee raised its median estimate for the federal funds rate at the end of 2015 to 1.375 percent, compared with its previous estimate of 1.125 percent in June. The Fed maintained its guidance that borrowing costs would be low for a "considerable time".

"The retention of the pledge that policy rates would be low for a 'considerable time' was a dovish element, balanced by increases to its interest rate forecast," Westpac Bank senior market strategist Imre Speizer said in a note. "Markets appear mainly focussed on the rate forecast and press conference, pushing US interest rates and the US dollar higher."
