A currency pair is the price of one currency expressed in terms of another — for example, how many US dollars it costs to buy one Australian dollar. Most Australian forex brokers quote dozens of currency pairs, and every forex trade you place involves buying one currency and selling another simultaneously.
How Currency Pairs Work — A Practical Example
Take the AUD/USD pair. If AUD/USD is quoted at 0.6500, it means one Australian dollar buys 0.65 US dollars. The first currency listed (AUD) is called the base currency, and the second (USD) is called the quote currency. The price tells you how much of the quote currency you need to buy one unit of the base.
Say you open a A$10,000 position on AUD/USD at 0.6500 using a CFD broker. If AUD/USD rises to 0.6600 — a move of 100 pips — your position gains roughly A$153 before costs. If the rate falls to 0.6400, you lose a similar amount. The direction of your trade determines whether you profit from the base currency strengthening or weakening against the quote.
Currency pairs are grouped into three categories. Majors (like AUD/USD, EUR/USD, GBP/USD) involve the US dollar and are the most traded and cheapest to trade in terms of spread. Minors pair two major currencies without the USD — for example EUR/AUD. Exotics pair a major currency with a smaller economy’s currency, such as USD/THB, and typically carry much wider spreads.
Why Currency Pairs Matter for Australian Traders
AUD/USD is the most relevant pair for most Australian traders because movements in it directly reflect the strength of the Australian economy versus the US economy. Commodity prices, RBA interest rate decisions, and global risk sentiment all influence this pair. Understanding what drives a pair’s price is just as important as knowing how to trade it technically.
ASIC-licensed brokers in Australia must display pricing transparently and cannot manipulate quotes against retail clients. Under ASIC’s Product Intervention Order, retail traders on forex CFDs are also subject to leverage limits — a maximum of 30:1 on major currency pairs and 20:1 on minors. This means a A$1,000 margin deposit controls a position of up to A$30,000 on AUD/USD. Higher leverage amplifies both gains and losses, which is why understanding leverage is critical before trading any pair.
When a broker handles currency pair pricing poorly — for example, by widening spreads dramatically during off-peak hours or slipping your execution at news events — it eats directly into your returns. Choosing an ASIC-licensed broker with tight, consistent spreads on the pairs you trade most is one of the most practical cost-control decisions you can make.
Currency Pair vs Exchange Rate
A currency pair is the instrument you trade — for example, AUD/USD as listed on your broker’s platform. An exchange rate is the specific price of that pair at a given moment — for instance, 0.6500. You will often hear them used interchangeably, but strictly speaking the pair is the market and the exchange rate is the current price within it. Knowing whether a quote is a live, streaming rate or a delayed indicative rate matters — most quality CFD platforms provide live prices. For most Australian traders, the spread on your chosen currency pair is the more important factor to check before opening an account.
What to Check When Comparing Brokers
- Spread on AUD/USD: This is your primary trading cost on the most popular Australian pair. Look for brokers offering spreads below 1 pip on AUD/USD during standard market hours — tight spreads compound into real savings over time.
- Number of pairs available: Some brokers offer 70+ pairs while others list fewer than 30. If you plan to trade minors or exotics, confirm your shortlisted broker actually offers them before signing up.
- Leverage limits by pair type: ASIC caps leverage at 30:1 for major pairs and 20:1 for minors. Confirm your broker applies these limits correctly, especially if you are used to offshore brokers offering higher leverage.
- Execution quality during volatility: Check whether spreads widen significantly around RBA announcements or US NFP data. Brokers like Pepperstone are known for tight, stable spreads even during major news events.
- Overnight swap rates by pair: Holding a position past the daily rollover incurs a swap charge that varies by currency pair and direction. Ask for the swap table before committing to a broker if you plan to hold trades overnight.
