AUD/USD: the Australian Dollar against the US Dollar

AUD/USD is a currency pair. The first currency, the Australian dollar (AUD), is the base. The second, the US dollar (USD), is the quote. The price tells you how many US dollars one Australian dollar is worth. If AUD/USD is trading at 0.6500, one Australian dollar buys 65 US cents.

When the price goes up, the Aussie is getting stronger against the US dollar. When it goes down, the Aussie is getting weaker. A "pip" is the standard unit of movement, the fourth decimal place, so a move from 0.6500 to 0.6501 is one pip.

AUD/USD is one of the most traded pairs in the world, which makes it a common starting point for people learning forex. It is a "major" pair, the group of the most heavily traded pairs that all include the US dollar.

Two economies set the tone here: Australia and the United States. Each has a central bank that sets interest rates. Australia's is the Reserve Bank of Australia (RBA). The United States has the US Federal Reserve, often called the Fed.

The gap between those two interest rates, called the interest-rate differential, is a big driver. When one central bank raises rates while the other holds or cuts, money tends to flow toward the higher-yielding currency, and the pair moves. Traders watch every RBA and Fed meeting, plus the inflation and jobs data that shape those decisions.

The Aussie is a commodity currency. Australia exports a lot of raw materials, especially iron ore and other metals, so commodity prices feed into AUD. China is Australia's largest trading partner, so Chinese growth and demand data move the Aussie too.

Finally, AUD/USD is sensitive to risk sentiment, the market's overall mood. The Aussie often rises when investors feel confident and falls when they seek safety, because the US dollar tends to act as a safe haven in stressed markets. So this pair can swing on global news, not just local data.

Forex runs 24 hours on weekdays across four main sessions. In UTC, roughly: Sydney runs about 22:00 to 07:00, Tokyo about 00:00 to 09:00, London about 08:00 to 17:00, and New York about 13:00 to 22:00. These shift by an hour when regions observe daylight saving.

For AUD/USD, the most natural activity comes during the Sydney and Tokyo sessions, when Australian and Asian markets are open and local data lands. That is the window where Aussie-specific news tends to hit.

The heaviest overall volume, though, comes during the London session and the London to New York overlap, roughly 13:00 to 17:00 UTC, when the most money is moving through the market globally. Liquidity is deepest then, so price can move quickly around US data releases.

AUD/USD is highly liquid, meaning there are always plenty of buyers and sellers. High liquidity usually means tighter spreads, the small gap between the buy and sell price that is one of your trading costs. As a major pair, the Aussie tends to have lower spreads than more exotic pairs, though the exact number changes constantly with the market and your broker.

Because it is a commodity and risk-linked currency, AUD/USD can move sharply on global headlines, sometimes more than its quiet ranges suggest. Treat it as a pair that reflects the world's mood, not just two countries.

A word on reality: trading is risky, and most retail traders lose money. Nothing about reading this page changes that. The point of learning a pair is to understand it, not to expect a payout.
