How to trade AUD/SGD: A guide to Australian dollar-Singaporean dollar trading

Reading time: 8 minutes

While the Australian and Singapore dollars share a strong connection with the Asia-Pacific economy, they respond to different economic forces. Australia’s currency (AUD) is largely influenced by commodity exports, economic growth and interest-rate decisions. Singapore’s dollar (SGD), meanwhile, is closely linked to the country’s trade position and its distinctive exchange-rate-based monetary policy.

These differences make AUD/SGD trading an interesting way to gain exposure to two important regional currencies. The pair also offers an opportunity to follow developments in China, commodity markets and Asian trade. If you’re learning how to trade AUD/SGD, it helps to understand what drives both currencies before looking at charts or placing an order.

What is the AUD/SGD currency pair?

AUD/SGD represents the Australian dollar against the Singapore dollar. AUD is the base currency, while SGD is the quote currency. The exchange rate tells you how many Singapore dollars one Australian dollar can buy. For example, if AUD/SGD trades at 0.8500, one Australian dollar is worth 0.85 Singapore dollars. If the rate rises to 0.8600, the Australian dollar has strengthened against the Singapore dollar. A fall to 0.8400 suggests the opposite.

AUD/SGD is a minor currency pair rather than a major pair, such as EUR/USD or USD/JPY. It does not include the US dollar, although movements in the USD can still influence both currencies and, indirectly, the exchange rate. Traders can gain exposure to the pair through different instruments, including spot forex and contracts for difference (CFDs).

What factors affect the AUD/SGD exchange rate?

Understanding the economies behind both currencies is an important part of trading the AUD/SGD currency pair. Here are some of the main influences traders usually watch.

Reserve Bank of Australia interest rate decisions

The Reserve Bank of Australia (RBA) sets the country’s cash rate to influence borrowing costs, spending and inflation. Its decisions can also affect demand for the Australian dollar.

Higher Australian interest rates, or expectations of further increases, may make AUD-denominated assets more attractive to investors. This can support the currency against the Singaporean dollar. Expectations of rate cuts may have the opposite effect. However, the market often reacts to what the RBA says about future policy, not just the rate decision itself. Inflation, employment figures and economic growth data can all influence these expectations.

Monetary policy in Singapore

Singapore has a different approach to monetary policy. Instead of using a policy interest rate as its main tool, the Monetary Authority of Singapore (MAS) manages the Singapore dollar against a trade-weighted basket of currencies. It uses a policy band for the Singapore dollar nominal effective exchange rate (S$NEER), adjusting its slope, width or midpoint when necessary to maintain price stability.

This difference is important for AUD/SGD trading. While RBA decisions are often discussed in terms of interest-rate changes, traders following Singapore's monetary policy should pay attention to MAS statements about the exchange-rate policy band.

Commodity prices and Australia’s exports

Australia is a major exporter of commodities, including iron ore, coal and natural gas. Changes in global demand and commodity prices can influence export earnings and sentiment towards the AUD. China is particularly important as it is a major destination for Australian exports, including iron ore. According to World Trade Organization (WTO) data, China accounted for 30.5% of Australia’s total exports in 2025.

Stronger Chinese industrial activity can support demand for Australian resources and may benefit the AUD. Conversely, weaker manufacturing or construction activity in China can raise concerns about commodity demand.

Singapore’s trade and financial activity

Singapore is a major trading and financial centre, with strong links to regional and global markets. Its economy is influenced by international trade, manufacturing, financial services and investment flows. Changes in global trade or demand for electronics and other manufactured goods can affect Singapore’s economic growth. These developments may influence expectations for the SGD, particularly when they affect inflation expectations and the MAS policy outlook.

Global risk sentiment

The Australian dollar is often viewed as a growth-sensitive currency because of Australia’s exposure to global trade and commodities. During periods of stronger risk appetite, demand for AUD may improve. When markets become unsettled, investors may favour currencies they consider more defensive, including the Singapore dollar. This relationship is not fixed. Both currencies can move in response to local economic data, monetary policy and wider market developments.

How to trade AUD/SGD: A step-by-step guide

Once you understand what moves the AUD/SGD currency pair, you can start building a trading plan.

Step 1: Choose a broker and trading platform

Compare the available AUD/SGD instruments, spreads, commissions and trading conditions. Check the broker’s regulatory status and understand whether you are trading spot forex or Contracts for Difference (CFDs).

Step 2: Analyse both economies

Traders commonly monitor RBA announcements, Australian inflation and employment data, and MAS monetary policy statements. They also monitor Chinese economic activity and commodity prices, as these can influence the Australian dollar.

Step 3: Decide whether to buy or sell

A buy position means you expect the AUD to strengthen against the SGD, while a sell position means you expect it to weaken. For example, if AUD/SGD trades at 0.8500 and your analysis suggests the rate could rise, you might consider a buy position. If you expect it to fall towards 0.8400, a sell position may better reflect your view. These are hypothetical price levels, not price forecasts.

Step 4: Set your position size and stop-loss

Traders typically decide how much they are prepared to risk before opening a trade. Their position size then reflects their account balance, risk limit and the distance to the planned stop-loss level. A stop-loss can help limit potential losses, although the final execution price may differ during volatile conditions or price gaps.

Step 5: Monitor and review your trade

Traders usually keep an eye on economic announcements and changes in market conditions. They record entry, exit along with their reasons for taking the trade. Reviewing your results can help you identify patterns and assess your approach.

Popular AUD/SGD trading strategies

There is no single strategy that works in every market condition. Beginners can explore three common approaches.

• Trend trading: You would identify an established upward or downward trend and look for opportunities in the same direction. Moving averages and trendlines can help assess market direction.
• Breakout trading: Traders generally watch for AUD/SGD to move beyond a recognised support or resistance level. A breakout may signal the start of a new price move, but false breakouts can also occur.
• Range trading: If the pair moves between established support and resistance levels, traders may look for potential trading opportunities near either boundary. This approach may become less suitable when the market develops a strong trend.

Whichever method is chosen, traders usually define entry and exit conditions in advance. They also tend to practise the strategy in a demo account before considering live trading.

When is the best time to trade AUD/SGD?

AUD/SGD is a regional currency pair, so activity during Asia-Pacific trading hours can be particularly relevant. The Australian and Singapore trading sessions overlap for several hours, providing an opportunity to follow developments in both economies. Liquidity and volatility can change around important economic announcements, including RBA decisions, MAS policy statements and Chinese data releases.

The best trading period depends on your strategy and the conditions offered by your broker. Check spreads and available liquidity rather than assuming that one session will always provide better trading opportunities.

AUD/SGD CFD trading: Leverage, margin and risk

CFDs allow you to speculate on AUD/SGD price movements without owning the underlying currencies. Depending on the broker and applicable regulations, you may be able to use leverage to control a larger position with a smaller initial deposit, known as margin. For example, a $10,000 position with 10:1 leverage would require $1,000 in margin, assuming those terms are available. A 1% adverse move in the position would result in a $100 loss before costs, equivalent to 10% of the initial margin.

Leverage tends to magnify the impact of price movements on both gains and losses on your account. Spreads, commissions and overnight financing charges may also affect the overall cost of a trade. Check your broker’s margin requirements and understand the circumstances in which positions may be closed. CFDs carry a high risk of loss, particularly when traded with leverage. This makes risk management crucial.
