The Australian dollar, nicknamed the “Aussie”, is one of the most traded currencies in the world. Traders usually follow it against the US dollar, quoted as AUD/USD. For beginners it is a fascinating currency, because its moves are tied closely to commodities, China and the general mood in global markets.
Reading AUD/USD
AUD/USD shows how many US dollars one Australian dollar buys. If the rate is 0.66, one Aussie buys 66 US cents. When the number rises, the Australian dollar is strengthening; when it falls, it is weakening.
Why the Aussie is a commodity currency
Australia exports huge amounts of iron ore, coal, natural gas and gold. When the prices of these goods rise, more money flows into the country and demand for Australian dollars tends to increase. That is why traders call it a commodity currency. Watching iron ore and metal prices, along with gauges like copper, can help explain moves in AUD/USD.
The China connection
China buys a large share of Australia’s exports, particularly iron ore used to make steel. Strong Chinese factory and construction activity usually supports the Aussie, while signs of a slowdown in China tend to weigh on it. Chinese economic data and policy decisions, including moves by its central bank to manage the yuan, are therefore worth watching for Aussie traders.
A barometer for risk appetite
The Australian dollar often rises when investors feel confident and falls when they become nervous. In risk-on periods, money flows into growth-linked assets, and the Aussie benefits. In risk-off periods, investors retreat to safer currencies such as the US dollar, the yen or the Swiss franc, and the Aussie usually weakens. Our guide to risk-on and risk-off explains this pattern in more detail.
Interest rates and the RBA
Like any currency, the Aussie responds to interest rates. Decisions from the Reserve Bank of Australia, and how they compare with rates in the US, shape the reward for holding Australian dollars. This week the RBA raised its cash rate to 4.85 per cent, a reminder that the Aussie is about more than commodities. Our Morning Market Brief covered the decision.
When the Aussie moves
Because Australia’s working day falls during the UK night, the Aussie is often most active during the Asian session. Key releases include the RBA’s decisions, Australian jobs and inflation figures, and Chinese data. These can move AUD/USD before London traders have had breakfast, so it pays to check overnight moves.
Common beginner mistakes
The first is treating AUD/USD as a pure bet on Australia, when it is often a bet on China, commodities and global mood all at once. The second is ignoring the US side of the pair: a strong US dollar can push AUD/USD lower even when Australian news is good. The third is trading it during thin overnight hours without allowing for sudden moves.
The takeaway
The Australian dollar is a useful teacher. Learn what drives it and you will learn a great deal about how commodities, China, interest rates and risk appetite connect. If you would like to test how well you understand those links, take the free Samuel & Co Trading Trader Assessment.
