This week the AU$ lost all the gainsand is back at 0.68 US$ like a month ago.You obviously havent noticed but the AUD has been having a very strong last 2 weeks - the carry trade is back on.
But the carry trading doesn't matter, it is just speculation and money that goes in AAA rating. The only way real money is coming into Australia now is because government is backing all loans Australian banks make. But in australia there is somewhat 3 trillions of debt and I'll bet the Australian rating will drop from AAA and interest rate will rise if we end up using taxpayer moeny to back up everything. To me is obvious that government backing loans can't go on forever and money inflow can dry up again.
