The Australian dollar is the worst performing currency as it continues to reel from shockingly weak inflation figures.

At 0630 AEST on Thursday, the local unit was trading at 75.84 US cents, down from 76.11 cents on Wednesday.

Despite usual knee-jerk volatility overnight following the US Federal Reserve's decision to leave interest rates unchanged, the Aussie is still being dragged down after the local quarterly consumer price index fell for the first time in eight years.
