Australia imports a lot of consumer goods and a lot of its inputs for industry and construction - so a high Australian dollar is a good thing for most people on the street. It is also good for Australian travellers abroad - and Australians love to travel.
However - Australia exports a lot of grain and agricultural products and also a lot of minerals (iron ore, alumina and many other metals) and energy resources (coal, natural gas and uranium) - which drives our wealth and standard of living. For exporters a high Australian dollar is not good thing and damages our competitiveness compared to our major trading competitors such as Brazil, Canada and the US.
I came across this blog article today (http://blogs.marketwatch.com/fundmastery/2009/11/16/can-china-dump-the-dollar/tab/print/) which has one of most thought through comments I have read recently on the dollar and the interdependence between the Chinese and US economies. Bottom line is that the US will not hurry to protect the declining dollar because it needs to maintain the interest of external investors in US nominated assets relative to the value of their own currencies.
And China can't rapidly liquidate the $2 trillion plus it holds in US dollar reserves because it doesn't really have any alternatives other than the Euro or the Yen - and neither are really attractive to the Chinese because they don't really have the trading depth or liquidity of the US dollar.
Then this article gets to the punchline - which is that the Chinese have developed a strategy to hold their sovereign wealth reserves also in commodities - hence their buying spree over recent months in base metals, soft commodities and fuels. Some of these have been going into the rebounding industrial production in China, which has been increasing again during 2009:
But a lot of the commodities bought by the Chinese are just sitting stockpiles - they have bought far more than than they will consume in the medium term. So the proposition is that the Chinese are storing value in commodities to reduce their reliance on their holdings of US dollars.
Still getting my mind around that one - it defies a lot of contemporary thinking and academic training - but after the meltdown of the global financial crisis - maybe people (and governments) just don't trust paper based assets any more - and are looking for something that won't disappear down a computer screen!
So getting back to the US dollar. Maybe it will start to be replaced as the currency of exchange - and we will see more trade in other currencies - or dare I say it - in gold! Look at the rise in gold (and silver) prices in recent years (source: www.the-privateer.com ).
We need to challenge a lot of accepted wisdom and really think about what is going on. I have a few Chinese friends who tell me their families hold value in gold. The Indians traditionally do too. There just might be something in this traditional wisdom.
