The major reasons why i dont see Australia having the same degree of economic pain as the US and UK (and i emphasise same degree) are:
1) This is a financial crisis caused essentially by lending to people who couldnt afford the asset and had the legal right to hand back the asset and underlying debt.
2) Our financial institutions have minimal involvement in the debt securities issued on the basis of point 1. We are more than 18 months into the credit crisis yet our banks are still generating profit, compare this to Iceland, UK and US where their financial institutions are haemoraging losses.
3) Australian lending rates where much higher going into this global recession. Hence Australian borrowers have a much higher buffer as interest rates come down. (In the last 6 months compare the huge differential interest cost savings of Australian borrowers compared to their US counterparts). This factor to me is one of the key supports of the Australian economy. We all complained in prior years when our lending rates were much higher than other countries, but at least now those higher interest rates will insulate the pain as interest rates fall, and again i emphasise here the rate of differential fall in the Australian borrowers lending rate compared to their US counterparts. Sure some Australians will loose their jobs and hence find themselves in financial difficulty in repaying the loans. But compare the increase in unemployment rates to reduction in interest rates and the stimulatory effect of the the reduction in interest rates will still be greater than the loss from an increase in unemployment. In simplistic terms what was the residential lending rate in early 2008 about 9%. If we see RBA target rates of 3% this should translate into residential lending rates of 5.5%. On an average loan of say $300,000 this translates into cost savings of $10,500 a year. This is a huge 'tax cut'. Sure there will be some recently unemployed for whom this may just act as an insulator before the inevitable, but for those still employed its an extra $200 a week in their pocket.
3) The benefit of the commodity boom was only indirect for most of the australian population (through the wealth effect from speculation in resource shares, through increased government tax receipts that were then partially redistributed to recipients not benefiting directly from the commodity boom etc). Hence its loss will also only be indirect. For those that were direct beneficiaries it will seem like the world has come to an end for the rest of us that never had a direct involvement the effect will be indirect and more muted (mostly in the form of loss of government revenue).
4) Australia's 'smallness' for want of a better word. Unfortunately the US is regarded as the global lender of last resort, essentially the world central bank (im not stating the correctness or otherwise of this, just that this is still the current underlying opinion of the world). Hence even though it is the catalyst of the global financial crisis, it is still regarded as being a global safehaven for cash. The problem here though is its impact on exchange rates. Basic economics suggests that the US currency should be depreciating, unfortunately with demand for its 'safe' currency the opposite is happening (and in my opinion this will lead to an extention in depressed global conditions than would otherwise be the case). Australia doesnt have this, hence the depreciation of its currency. Essentially this is good for australia as it will improve the future trade situation (through an increase in exports and increased competitiveness of import replacement industries (however for import replacement industries there is a significant time lag as it takes time for capital to be allocated to it, essentially what Paul Keating referred to as the J-curve effect).
5) Our proximity to Asia. Although Asia will incur a down turn because of its export dependency model to the west, Australia provides many key resources that will still be in demand (resources, foodstuffs, education, immigration), with the AU$ depreciating our industries become more competitive. Sure recources will not be as attractively priced, but they will be insulated by the falling AU$ (from memory we still managed to surivive prior to the resource boom starting 2002 odd
)
Again i stress i dont think everything is going to be hunkey dorey in 6 months time i just dont see Australia being effected to the same degree, and hence i am investing accordingly.
