What has received much less attention, but should be taking over the discussion of where the growth is coming from, is the export sector.
The most recent data shows that the value of exports growing at an annual pace of a very robust 18 per cent. This has seen the balance on international trade move to a sizable surplus of a little over $1 billion for the last few months. The volume of exports has increased at an impressive 6.5 per cent in the past year and has registered seven straight quarterly increases.
What is even more impressive about the export efficiency of the Australian economy and the resources sector in particular, is that the export transition has occurred despite some signs of less robust economic growth in China.
Encouragingly, China is easing its domestic policy settings at the moment as it works to support its economy from the second half of 2014. When China succeeds in locking in GDP growth around 7 to 7.5 per cent, Australian exporters will continue to be major beneficiaries and Australia's trade performance will continue to improve.
In addition to the massive boost to output from mining, the lower Australian dollar has also aided the export sector. For the last six months or so, the dollar has hovered around 90 US cents, well down from the level around 105 US cents a year ago. This depreciation has helped to give Australian mining companies a competitive boost and has helped support other exporters and those firms competing with imported goods and services.
The fact that exports are registering such stellar growth and the trade balance is comfortably in surplus suggests that the Australian dollar, around current levels of 90 US cents, is not over-valued.
Indeed, one very important benchmark in judging whether a currency is over or under valued is to look at the trade and export performance. If a currency was over valued, for example, as the Reserve Bank of Australia and others have suggested in recent times was the case for the Australian dollar, it would manifest itself in a poor trade performance. In simple terms, exports would be faltering under the pressure of a market misalignment.
The fact that Australia's export and trade performance has been improving at a rapid pace when the dollar was around 90 cent suggests the RBA and others need not worry about an over valued currency. Indeed, so strong is the trade turnaround that some may suggest the Australian dollar is undervalued at recent levels particularly what is happening to commodity prices and domestic growth.
It is not just mining that is registering an improved export position. Inbound tourism is growing rapidly and after a particularly troubling few years, education exports are also lifting. There are also some encouraging signs that agricultural exports are also expanding to round out a more favourable picture.
In all, it appears that one of the critical elements needed for the economy to transition from the mining investment boom to other sources for growth is occurring. The surge in exports over the past year or two is set to continue and this will see the export sector being a significant contributor to bottom line GDP growth. With any further momentum in dwelling construction and household consumption expenditure, as has been the case since the middle of 2013, the overall rate of economic growth is on track to reach and even exceed its long run trend for the next couple of years.
Australia does not have a reputation as a particularly efficient export economy. Years of wide trade deficits and quite alarming current account deficits have at times created a perception of risk and instability. This is changing and indeed it is quite possible that over the next few years will record surpluses on its current account and Australia will be seen as an export powerhouse.
