Today, the Australian Bureau of Statistics released the – December-quarter 2016 National Accounts data – which showed that real GDP had rose by a strong 1.1 per cent after recording a negative 0.5 per cent outcome in the September-quarter 2016. Annual growth (last four quarters) was 2.4 per cent. The December-quarter result was driven by strong household consumption growth (even as wages growth was negative), public investment and net exports (on the back of a massive shift upwards in the terms of trade). A bright spot was the positive private investment growth. However, I consider the overall outcome to be an unstable situation. Households cannot continue to dominate the growth outcome when wages are flat or falling and the household debt ratio is already at record levels. The decline in the household saving ratio cannot be sustained. Further, public investment is spiky (large public infrastructure projects) and could just as easily turn negative next period. The overall trend in government intent is to cut back its contribution to growth in the coming year. Which means that growth becomes dependent on the swings in the terms of trade, which fluctuate substantially.
