Australian Dollar FAQs

What key factors drive the Australian Dollar?

One of the most significant factors for the Australian Dollar (AUD) is the level of interest rates set by the Reserve Bank of Australia (RBA). Because Australia is a resource-rich country another key driver is the price of its biggest export, Iron Ore. The health of the Chinese economy, its largest trading partner, is a factor, as well as inflation in Australia, its growth rate and Trade Balance. Market sentiment – whether investors are taking on more risky assets (risk-on) or seeking safe-havens (risk-off) – is also a factor, with risk-on positive for AUD.

How do the decisions of the Reserve Bank of Australia impact the Australian Dollar?

The Reserve Bank of Australia (RBA) influences the Australian Dollar (AUD) by setting the level of interest rates that Australian banks can lend to each other. This influences the level of interest rates in the economy as a whole. The main goal of the RBA is to maintain a stable inflation rate of 2-3% by adjusting interest rates up or down. Relatively high interest rates compared to other major central banks support the AUD, and the opposite for relatively low. The RBA can also use quantitative easing and tightening to influence credit conditions, with the former AUD-negative and the latter AUD-positive.

How does the health of the Chinese Economy impact the Australian Dollar?

China is Australia’s largest trading partner so the health of the Chinese economy is a major influence on the value of the Australian Dollar (AUD). When the Chinese economy is doing well it purchases more raw materials, goods and services from Australia, lifting demand for the AUD, and pushing up its value. The opposite is the case when the Chinese economy is not growing as fast as expected. Positive or negative surprises in Chinese growth data, therefore, often have a direct impact on the Australian Dollar and its pairs.

How does the price of Iron Ore impact the Australian Dollar?

Iron Ore is Australia’s largest export, accounting for $118 billion a year according to data from 2021, with China as its primary destination. The price of Iron Ore, therefore, can be a driver of the Australian Dollar. Generally, if the price of Iron Ore rises, AUD also goes up, as aggregate demand for the currency increases. The opposite is the case if the price of Iron Ore falls. Higher Iron Ore prices also tend to result in a greater likelihood of a positive Trade Balance for Australia, which is also positive of the AUD.

How does the Trade Balance impact the Australian Dollar?

The Trade Balance, which is the difference between what a country earns from its exports versus what it pays for its imports, is another factor that can influence the value of the Australian Dollar. If Australia produces highly sought after exports, then its currency will gain in value purely from the surplus demand created from foreign buyers seeking to purchase its exports versus what it spends to purchase imports. Therefore, a positive net Trade Balance strengthens the AUD, with the opposite effect if the Trade Balance is negative.

tion report. Traders will take more clothes from Australia’s Trade Balance data later on Thursday.

Data released by the Australian Bureau of Statistics (ABS) on Wednesday showed that the country’s Consumer Price Index (CPI) rose by 3.4% YoY in November, compared to 3.8% in October. This figure came in softer than the estimates of 3.7%. Meanwhile, the monthly CPI came in at 0% in November, following the previous reading of 0%.

The cooling inflation has tempered market expectations for a rate hike from the Reserve Bank of Australia (RBA) in early 2026. The Aussie attracts some sellers in an immediate reaction to the CPI inflation report.

Investors seem uncertain about the pace of policy tightening by the Bank of Japan (BoJ), which might weigh on the JPY. Most economists anticipate the next rate move around the middle of 2026, though a sooner hike is possible, partly due to concerns about the weak JPY.

However, verbal intervention from Japanese officials might cap the downside for the JPY in the near term. Japan's Finance Minister, Satsuki Katayama, said that the government will take "appropriate measures" against excessive currency volatility.
