Much remains to still be seen as the US dollar gains strength (I'm following this with interest) — not entirely unexpected. The Australian dollar like a few other currencies, is influenced is by Asian economic performance — especially China; there is weak economic data coming out of China at the moment (marked slowdown in electricity production is a key indice of China's industrial performance) so the AUD is falling while the US dollar is rising, the yen is falling... you get the picture — lots of selling off going on across currencies. All this could influence future prices, but not in the immediate term.
While the dollar is gaining against the yen, the dollar keeps losing against the Chinese yuan. I am paid in dollars, but my salary is delivered in yuan so I get less and less each month!
