The aussie has been able to shake off bad news recently so how will it cope with more bad commodity price news

The Iron ore 62% delivered to Qingdao contract fell below $40 and to the lowest since May 2009 today on worries about Chinese demand and increased production

Chinese stockpiles have risen to the highest in around 7 months and producers such as BHP and Rio Tinto have taken a leaf out of OPEC's book in increasing supply to defend their market share

As a big resource for Australia the continued drop in prices heaps more pressure on the commodity side of the economy

AUDUSD looks only mildly concerned having fallen from around 0.7335 to a few pips under 0.7300 as I type

The 0.7387 area has become a strong resistance level for the pair and is the 38.2 fib of the May 2015 drop

AUDUSD daily chart

While the aussie has been able to shrug off bad news and a more neutral RBA, there's only so much news it can take on its shoulders before it starts to sag.

It seems that China growth news is always simmering in the background and increased market nervousness comes in waves. Now that the ECB has cast their stone for the next few months and the Fed will cast theirs next week, the market will no doubt go looking for the next bone to chew on, and there's a very high chance that China will be it...again. If that's the case then there's more fun times ahead for the aussie
