The Australian and New Zealand dollars retreated on Friday as a broad-based rally in the US dollar weighed on commodity-linked currencies.
The Australian dollar traded flat at $0.6973, having slipped 0.4% overnight and pulling back from resistance near $0.7026.
The New Zealand dollar followed a similar downward trajectory, reflecting the broader weakness in risk-sensitive assets.
The sell-off was driven by a further surge in oil prices, which stoked inflation concerns and supported the greenback.
Higher energy costs typically strengthen the US dollar by reinforcing the case for tighter monetary policy or by increasing the trade balance advantage for the US as a net energy exporter.
Meanwhile, bond markets faced selling pressure, with yields rising as investors adjusted positions ahead of key economic data.
