For the boys over there... the papers are saying that if the oil price rises towards $80/barrel then it'll put downward pressure on the Australian Dollar...
...if it stays around $55/barrel then it'll have no impact on the dollar.
The reason why the Australian Dollar strengthened against the US Dollar the last few days is because the US Dollar fell sharply against the Euro... that'll be another one to watch for.... a continuing rise of the Euro against the US Dollar...
