Unable to trigger barriers at the 0.8500 level, AUD/USD has been undermined by by a bout of risk aversion. Equities have fallen 1.6% so far in US trade, commodities are under pressure, particularly copper, the strongest of the bunch on the recent run higher.

Yesterday’s pullback low at 0.8365 has given way as Aussie has dipped to 0.8350 thus far. 0.8320/40 is a congestion area, and might slow the slide.
