The New Zealand dollar fell after reports that the European Central Bank may consider taking more steps to stimulate the euro-zone economy, stoking demand for the greenback.
The kiwi fell to 79.55 US cents at 8am, having peaked at 80.33 cents, and down from 79.85 cents yesterday. The trade-weighted index was little changed at 77.21 from 77.26.
The greenback rallied after the ECB bought Italian covered bonds for a second day as part of a plan to boost lending in the region, and after Reuters cited unnamed sources saying the European monetary authority was considering corporate debt purchases to support the regional economy. The ECB said no such decision had been taken. The US dollar was also supported by better-than-expected US housing data.
"The ECB was the one story to write home about," said Imre Speizer, market strategist at Westpac Banking Corp in Auckland. "The kiwi's in a range - there's a slight ascendancy, but it's not really showing any strong direction."
