In addition, people make the mistake in looking at currency values as some kind of measure for economic performance. It's NOT. Much better to look at unemployment figures or the FTSE.
If it was, then why isn't the Dutch, Australian and Swiss currencies the strongest in the world. They have the strongest economy in the OECD so shouldn't those currencies be strong?
The answer is NO. Particularly in Australia's case which is a commodity exporter.
The opposite is true. An expensive AUD generally has adverse affects on the economy. A lower AUD is seen to be advantageous to competitiveness. If Australia had Cyprus Pound values, then the economy would be in meltdown because it wouldn't be able to sell all its commodities.
