THE Aussie dollar has spent months rallying hard against the greenback - but new figures suggest it might not have anything left in the tank.
While the rest of the world's currencies hold strong and even rise above the US dollar, the Australian dollar is faltering.
Earlier today, the Australian dollar tumbled as much as 1.5 per cent and fell as low as US79.21 cents.
By 8am, the Australian dollar was down 1.4 per cent and sitting at US79.28 cents.
Some experts suggest the Aussie dollar might recover and keep climbing above the 80 cent mark - others aren't so sure.
"As was the case late last year when the AUD looked excessively weak, we do not think that the current state of affairs is sustainable," Mr Been said.
"First, the AUD is currently at an extreme in term of its correlation to commodities, beta and the DXY, all of which have pointed to strength. If this correlation declines and rates - which are signalling weakness - once again become more important, then the AUD will likely fall.
"Second, should these strong correlations manage to hold, we see risks that, at least on a tactical basis, there is scope for commodities to ease, for risk sentiment to sour and for the USD to once again find its feet as the recent strength/weakness in all these factors is at a historical extreme."
The Australian dollar experienced its largest weekly decline in more than a year thanks to its 1.5 per cent drop overnight.
It's also expected to continue dropping as the Federal Reserve keeps pushing up interest rates and the Reserve Bank of Australia keeps borrowing rates low.
"In the medium term, the Australian economy does not welcome a stronger Australian dollar. Plus, I expect commodity prices to moderate," he said.
Tony Bradley from the Sydney-based Hunter Burton Capital hedge fund, said the outlook is bleak for the Aussie dollar - and said it's inevitable it will drop below 70 cents.
But it isn't just the Aussie dollar taking a hit.
The US dollar fell to a more-than-three-year low against the euro on Friday, extending recent losses on expectations European Central Bank policymakers are preparing to reduce stimulus.
