It has been just over three months since the December budget update but once again the government has been gifted a windfall of unexpected revenues, despite a raft of economic data suggesting the economy has slowed its rate of growth.
This is because the things that really matter to the budget have all done better than was expected by the Treasury just months ago. Strong conditions in commodity markets and lower unemployment mean that in the current financial year the budget bottom line will be about A$3 billion better than had been expected in December, and about A$12 billion better next financial year.
Since the last budget only last May, the outlook for 2018-19 has improved by A$12.3 billion and the outlook for 2019-20 by $13.8 billion.
Rising commodity prices and export volumes have pushed up the profits and tax bills of mining companies.
Iron ore is the standout. Prices have exceeded the Treasury’s December forecast on the back of lower international supply (a result of the tragic dam wall collapse in Brazil) and continued growth in demand from China.
In December, Treasury expected iron ore prices to average US$55 a tonne. But in fact they have averaged about US$75 a tonne. That alone will add about A$2 billion to government revenues in 2018-19 and, if maintained, A$6 billion in 2019-20.
Add in a weaker Australian dollar and the combined effect will account for almost half of the net improvement in the overall budget position this financial year and the next.
Iron ore is only one of our exports.
Coal prices have also exceeded expectations, which should add another A$1 billion to A$1.5 billion to revenue over the next two years.
And there’s more to it than mining. Corporate profits have generally been strong despite some storm clouds forming around the banking industry and the economy more generally.
Another thing driving the better budget starting point is strong jobs growth and a lower than expected unemployment rate, boosting the government’s financial position through lower unemployment benefits and a higher personal tax take. The February employment statistics showed an unemployment rate of 4.9%.
The Treasury had expected the rate to fall more slowly, only getting to 5% by June and then staying there for several years.
If the budget cupboard was untouched, which it won’t be, the budget would have a deficit of next to nothing this financial year and an impressive surplus as high as 1% of gross domestic product next year, a year ahead of the government’s schedule.
But it mightn’t last
These upside surprises from the corporate tax take can just as quickly go the other way.
Assuming they will last, as budgets often do, would be to make the same mistake as the Howard-Costello government, which made permanent changes to tax rates and commitments on the back of revenue that prove to be temporary. So did the Gillard-Swan government some years later with its “spreading the benefits of the boom” package.
Corporate profits might struggle to improve in future years in an increasingly difficult economic environment. No one knows what will happen with commodity prices. Right now China is using infrastructure spending to stimulate its economy, but it won’t always do that. Eventually its growth will be less metal-intensive.
But with the government well behind in the polls, I doubt these considerations are getting much attention.
China drives budgets, the US drives rates
The US economy sets the global price of money, which in turn determines the environment in which our Reserve Bank sets Australian interest rates and works out how to deal with the bursting of the housing bubble, which was itself in no small part the result of an easy US monetary policy in the wake of the global financial crisis.
China, on the other hand, determines the global price of commodities and trade flows and so helps determine corporate profitability in Australia.
This contrast between the two has never been greater, with the government flush with unexpected revenues while the Reserve Bank walks a knife-edge of low real economic growth, financial stability risks, and already easy monetary policy.
It is best summed up in this chart of real and nominal gross domestic product, which shows annual growth in real GDP (which affects the economy) slowing to 2.3% while growth in nominal GDP (which drives the dollars flowing into the Treasury) growth climbing to more than 5%.
