Globally the Australian dollar surged on Thursday after the country's employment data came in way above expectations, while the yuan marched higher after China moved to stem its currency's decline by relaxing a cross-border financing rule.
Data out on Thursday showed that Australia's employment handily beat expectations for a second straight month in June as net employment rose by 32,600 in June from May, exceeding market forecasts for an increase of 15,000.
That pushed the Aussie up and it spiked more than 0.9% to an intra-day high of $0.6834, taking the New Zealand dollar along with it.
The kiwi gained 0.57% to $0.6299, with both Antipodean currencies on track to reverse four straight sessions of losses.
"The Australian dollar has spiked higher across the board after the economy delivered another rate-hike defying report," said Matt Simpson, senior market analyst at City Index.
