Mining’s March quarter boom not as loud as it sounds
And the smarties told you the resources boom was finito. Now, it’s being given most of the credit for this week’s news that the economy grew by a rip-roaring 1.1 per cent in the March quarter and by an above-trend 3.5 per cent over the year to March.
The boom is far from finished. It will be adding to – and subtracting from – the growth in real gross domestic product for several years yet.
Media reports that ”the mining industry accounted for about 80 per cent of growth in GDP in the March quarter” come from no lesser authority than the Australian Bureau of Statistics itself. Sorry to say it, but this is true from a certain perspective, but essentially misleading.
It comes from the estimate that the mining industry’s volume (quantity) of production grew by an amazing 8.6 per cent during the quarter, which means it made a contribution of 0.9 percentage points to the overall growth in real GDP of 1.1 per cent.
Almost all that increased production would have been exported. So it explains most of the growth of 4.8 per cent in the volume of total exports during the quarter, which itself made a contribution of 1.1 percentage points to the overall real growth in real GDP of 1.1 per cent.
But that’s not the only way the mining sector affected the economy’s growth during the quarter.
Overall, business investment spending fell by about 1 per cent during the quarter. But Kieran Davies, of Barclays bank, estimates this was composed of a fall of about 8 per cent in mining investment, plus a rise of about 3 per cent in non-mining business investment.
And that’s not all. The accounts show the volume of imports fell by 1.4 per cent in the quarter, which, since imports subtract from gross domestic product-ion, means their fall made a positive contribution to the overall growth in real GDP of 0.3 percentage points.
But if the economy is roaring along, why on earth would imports be falling? Because such a high proportion – about half – of spending on new mines and natural gas facilities goes on imported capital equipment. And if mining investment is falling, imports of mining equipment must be, too.
The resources boom, which began a decade ago, has had three stages: first, the huge rise in the prices we get for our exports of coal and iron ore; second, the massive investment in additional mining production capacity; third, a big increase in the volume of our exports of minerals and energy as the new mines come on line.
We are still being affected by all three of those stages. Export prices peaked in mid-2011 and have since fallen a fair way, although they remain a lot higher than they were before the boom started. Prices fell further during the quarter and, although this doesn’t affect real GDP directly, it does represent a loss of real income to the economy, which must dampen demand indirectly.
Mining investment spending peaked in 2012 and has since started falling. It fell further during the quarter and this subtracted from growth, although less so when you take account of the related fall in imports of equipment.
Since so many mining construction projects are finishing, production is now growing strongly. It grew particularly strongly in the quarter because we didn’t have any floods or cyclones to disrupt it. But although mining production has a lot further to grow, it can’t keep growing as fast as it did this quarter.
Putting all that together, the mining sector’s net contribution to growth during the quarter accounts for not 80 per cent of the growth during the quarter, but just under half, meaning the ”non-mining sector” contributed just more than half.
And that’s good news. Why? Because this quarter’s mining performance was the exception to the new rule. Mining made a net positive contribution because mining investment didn’t fall as much as it could have, while mineral exports grew by a lot more than could have been expected. And neither of those two things can last.
The new general rule is that mining has been and will continue to make a net negative contribution to overall growth. That’s because the fall in mining investment spending outweighs the rise in mineral exports, even after you allow for the fall in mining-related imports.
The good news is that just more than half the growth didn’t come from mining. This is good news because for at least a year we’ve been worried about the economy ”rebalancing”, making the ”transition” from mining-led to broader-based growth.
And even though the bureau did its (inadvertent) best to hide the fact from us, its accounts show that non-mining growth is at last taking hold. Consumer spending grew by a not-so-wonderful 0.5 per cent during the quarter, but by an almost-OK 2.8 per cent over the year.
Home building grew by a rapid 4.7 per cent – the first really strong quarter. Best of all, by Davies’ estimate non-mining business investment grew by about 3 per cent.
Economists usually can’t see the future with any clarity, but the mining investment boom is different. Because it consists of a relatively small number of hugely expensive projects, it isn’t hard to see how close they are to finishing and whether there are many new projects getting going.
They are, and there aren’t. The macro managers have known for ages that mining will give the economy a big (net) dump in 2014-15 and 2015-16. That’s why getting the non-mining economy going is vital.
It’s why the Reserve Bank has kept interest rates so low and won’t start raising them until it knows we are out of the woods. It’s also why, despite all his budget cuts, Joe Hockey made sure they don’t do much to dampen demand until 2017-18.
