"The US economy hasn't been doing as well as had been hoped. The base case scenario (for a Fed hike) has now moved to December and there's a lot of commentary that they may have to wait for 2016."

With the Fed unmoved, focus had returned to specific factors driving the kiwi and Australian dollars.
Australian second-quarter gross domestic product rose just 0.2 per cent in the second quarter, half the pace expected, while property auction clearance rates were the slowest in three years, suggesting the housing market may have peaked. In New Zealand, second-quarter GDP rose a smaller-than-expected 0.4 per cent and the Reserve Bank has flagged it may make another quarter-point cut to the official cash rate after lowering the rate to 2.75 per cent on September 10.
"For the Aussie and the kiwi, more significant declines are likely to be in the offing as an easing bias and problems in the domestic economies start to weigh on those currencies," Nicholson said.
The local currency fell to 88.60 Australian cents from 88.93 cents on Friday and slipped to 4.0439 Chinese yuan from 4.0703 yuan.
The kiwi declined to 76.14 yen from 76.77 yen on Friday, and fell to 56.15 euro cents from 56.68 cents. It dropped to 40.89 British pence from 41.20 pence on Friday.
The two-year swap rate was unchanged at 2.68 percent, five-year swaps rose 2 basis points to 3.04 percent and 10-year swaps rose 3 basis points to 3.56 per cent.
