Higher volatility => higher currency risk => lower foreign investment
Inflation is covered by points 2. and 3.
High inflation hurts growth lowering employment and destroys wealth.
Aware of the above, my point was about the ambiguity of the RBA's stated goals. There is never any specificity about their goals, and that is clearly intentional. Gives them lots of wiggle room to change their opinion.
One of the things to bear in mind here is that this isn't so much Aussie strength as USD weakness.
I have just got back from a month in Asia and many countries are having the same discussion about the "strength" of their currency and the possible negative impacts on trade...
Of course if "everyone" has a strong currency except the US (&UK), then perhaps the better way to look at this is that its USD weakness rather than AUD strength....
Above is all true, especially the bold.
Which goes to my earlier point about what benchmark to use when measuring "stability". Stability against what? The USD? GBP? Euro? TWI?
If one narrowly uses the US as a benchmark to indicate AUD strength, then that may be misleading. A strong AUD/USD may only hurt exports to the US (and those who peg their currency to the USD).
If the AUD is not comparatively strong against other currencies, exports may not be affected all that greatly, especially where commodity and forex prices have been locked in well before the recent AUD/USD move.
