As the second half of 2018 unfolds, factors that usually have the greatest influence are skewing the AUD downwards. This means it is more likely than not that the AUD will fall to 70 cents or lower by this time next year. A move to 65 cents, around 10% down on current levels, is likely if some of the key drivers reassert historic influence, most notably, interest rate differentials.
Such a currency move would have implications for the economy, economic policy and other markets, including for stocks and bonds.
Three key downside risks:
1. Interest rate differentials
All Australian interest rates along the yield curve from the cash rate to the 10 year government bond and beyond, have fallen below those in the US. This should have been a factor undermining support for the AUD as investors look for higher nominal returns from the US. What is often overlooked in this era of global investment flows, is that even though the Australian yield curve is below the US curve, many other high industrialised countries have yields still well below those in Australia.
Look at the yields in the Eurozone, Japan, the UK and Canada. These markets have an interest rate structure that is materially lower than in Australia. As a result, these markets remain less attractive from a nominal yield perspective, at least relative to Australia, providing some support for the AUD or at least stemmed the decline.
Recent monetary policy tightening from the Federal Reserve and the Banks of England and Canada are starting to close the interest rate gap. This suggests AUD weakness is likely if rate hikes continue and the RBA remains on hold. But with the Bank of Japan and the European Central Bank firmly on hold with super stimulatory policy, an AUD free fall will be unlikely.
2. Commodity prices
The moderation in global growth since the start of 2018, has seen various commodity indices track lower. So far, this has had little impact on the AUD, partly as the price of iron ore has held up well, relative to the price of other commodities. Australia’s international trade performance has also been solid, as seen in the run of surpluses on the monthly international trade balance.
As a barometer of global economic growth and hence the AUD, broad commodity price indices are usually reliable. The 8% drop in the Bloomberg Commodity Price index in recent months fits with news of less solid growth in China, the Eurozone, the UK and Japan. For the AUD, the trend is threatening to undermine key support for Australian income growth. Hence the economic growth and monetary policy pressures.
Over the next six to 12 months, global economic conditions continue to moderate, including in the US as the sugar hit of the Trump tax policies start to fade. The risk is for further weakness in commodity prices and additional downside pressures for the AUD.
3. Political, economic or policy risk
Foreign investors shy away from a country and its currency when risk builds. That risk can be political, economic or policy driven and includes an assessment of civil unrest or natural disasters. In Australia, we face the prospect of the RBA keeping interest rates too high for too long which could require unexpected and outsized rate cuts in 2019 and 2020 to return the economy to an even keel. Local rate cuts with the rest of the world on hold or tightening would undermine the AUD.
A key reason for downside risk to growth and interest rates, is the fall in house prices, which for now have been orderly and not too extreme.
If prices remain weak and pose a further threat to household wealth, as well as to consumer spending and bank balance sheets, the RBA would quickly and pragmatically move to lower interest rates. Then there is risk associated with the Federal election, which is due at some stage before the middle of 2019. Will we see policy flip flops, back flips and downright dumb issues coming to the fore? Any such policy brain-snaps would make the headlines and create anxiety for international investors are hence the AUD.
What will a lower AUD mean for bonds and stocks?
A lower AUD, when linked to fundamental economic shifts, is good news. The export sector kicks higher, import competition is reduced and firms with an export focus or who compete with importers will gain. A lower AUD also adds to the attractiveness of Australian assets, including AUD denominated debt, as investors try to pick the low point for the currency. Foreign investors are more likely to buy the AUD when the exchange rate is 70 cents than when it was 90 cents and higher.
Borrowing in the local market can also be cheaper for foreign issuers, adding to supply of new debt instruments that local investors can access.
On balance, the risks favour a fall in the AUD from now through to the middle to latter part of 2019. On the assumption of a further deterioration in the interest rate differentials, a 10% fall in commodity prices from current levels, some risk pricing as house prices fall and the election campaign hotting up, the AUD could ease to 65 cents. Falls below this would require a very troubling outlook for the economy which, for now, seems unlikely.
Only if there is an unexpected surge in global and domestic activity and an early rate hike from the RBA, will the AUD hit 80 cents. In economics and markets, nothing can be ruled out, but on the balance of current facts and pressures, it is the downside that looks more likely for the AUD over the next year.
