There’s a confluence of circumstances forcing the Australian dollar up into previously unexplored territory, the latest of which was the unexpectedly high inflation numbers for the June quarter. This immediately ended speculation that the Reserve Bank might lower official interest rates sometime this year. Now it appears the only direction for rates is up.

It was that realisation and the new conviction that a rate rise or two is now firmly on the cards — triggered by not just the level of inflation recorded in the June quarter but its broad base — that saw the dollar push up above $US1.10 to levels not previously attained in the 27 years since it was floated.

That little surge, however, is only the latest blip in what is now a lengthening story of an increasingly strong Australian dollar. The Aussie is behind only the Swiss franc among developed economies in terms of its performance against the US dollar this year. It has appreciated more than 11% against the greenback since the start of this year.

It is no coincidence that Switzerland, traditionally a financial safe haven, and Australia have been the major beneficiaries of a global search for security. With the help of terms of trade that are, thanks to China and to a lesser extent India, at their highest levels for perhaps a century and a half, the Australian economy is one of the best-performing of any in the developed world.

The exposure created by the resource sector to developing Asia, but particularly China, is underpinning growth and providing a longer-term growth story for offshore investors and a proxy for a more direct exposure to the China story that its heavily managed currency cannot.

That back story is like a magnet for international investors, including central banks and sovereign wealth funds, looking for safe havens for their funds.

The Eurozone is a basket case, inextricably entangled with the stability of its weakest member states, of which there are several that would default without bail-outs.

The US is in a not dissimilar place, with its plight complicated further by the self-destructive stand-off between Obama and the Republicans over the raising of the country’s debt ceiling.

Even without that politically flavoured brinkmanship — even if a compromise is agreed in the next day or two — there is a very real prospect the AAA credit rating that Americans have come to take for granted will be lost as a result of the overwhelming challenges the country faces in bringing its debt and deficits under control. It also has helped that the US has actively devalued the greenback with its massive “quantitative easing” programs in response to the financial crisis.

No one would sensibly commit new funds to the US in those circumstances, at least until the uncertainties are resolved and the US dollar, which has been in free-fall, stabilises.

Australia, with one of the most stable economies — thanks to the resource sector and despite the challenges the high dollar is already causing for the structure of the economy and its capacity to respond quickly to the shifts in activity — looks even more attractive, given that it is already running the highest real interest rates in the developed world.

With further upside now on both the rates and the currency and the paucity of obvious alternatives, it isn’t surprising that foreign money is flowing in.

Inevitably, given the ability to borrow at low rates in the US and invest in much higher rates in a strengthening currency in Australia (shorting the US dollar in the process), there would also be a deep layer of purely speculative/arbitrager activity occurring.

The rapidity with which the dollar has run up in value is a concern. It is evident that the non-resource sector is struggling to adjust to the changing conditions. Confidence hasn’t been helped by the instability and unpredictability in Canberra and in the policies flowing out of the hybrid government.

Exporters are being damaged by the strong dollar while importers are finding it difficult to retain any of the windfall gains because of the fragility of business and consumer confidence. The dollar has run up so quickly and so steeply that there hasn’t been much time to adjust to the new circumstances.

And now the prospect of the RBA doing anything that might take some of the pressure off the non-resource side of the economy and inject some optimism into it has receded with the inflation numbers.

It is quite conceivable, provided the Chindia narrative remains uninterrupted and the US remains mired in its debts, deficits and increasingly ugly political impasses, that the Aussie could continue to strengthen.

If, however, China — which has some internal issues of its own with inflation — were to significantly slow, and/or the Americans were somehow able to come up with a sensible long-term strategy to return to sustainable public finances, the elevated levels at which the Aussie is trading against the greenback could be setting it up for a steep and potentially destabilising fall.
