Fixed Spread vs Variable Spread — Which Is Better for Australian Traders? (2026)

This article compares fixed and variable spreads for Australian forex and CFD traders who want to know which option will cost them less over time. For most active traders, variable spreads win on cost — but fixed spreads have a legitimate place depending on how and when you trade.

Quick Comparison — Fixed Spread vs Variable Spread

What Is a Fixed Spread?

A fixed spread is a set difference between the buy and sell price of a currency pair that does not change regardless of market conditions. Your broker guarantees that spread whether the market is quiet or in the middle of a major news release.

Fixed spreads are almost always offered by market maker brokers. The broker takes the other side of your trade internally, which is how they can afford to lock in that cost. The trade-off is that fixed spreads are typically wider than variable spreads during normal conditions — you pay a premium for the certainty.

For example, if you trade AUD/USD with a fixed spread broker, you might always pay 2.0 pips. At a standard lot size (100,000 units), that 2.0 pip spread costs you roughly A$20 per trade (assuming AUD/USD near 0.64). That cost is the same at 2am or during a Reserve Bank of Australia announcement.

What Is a Variable Spread?

A variable spread changes in real time based on liquidity and market activity. When the market is liquid and calm, spreads can drop to near zero on major pairs. When volatility spikes — around economic data releases or central bank decisions — spreads can widen dramatically within seconds.

Variable spreads are standard on ECN and STP broker accounts, where your orders are sent directly to liquidity providers. Because there is no middleman setting prices, the spread reflects the actual market. This means lower costs most of the time, but no guarantees during turbulent conditions.

Using the same AUD/USD example, a variable spread ECN broker might charge 0.1 pips during the London–New York overlap session. At a standard lot, that is roughly A$1 per trade — a fraction of the fixed spread cost. The same broker might widen to 3.0+ pips during the RBA rate decision, so timing your entries matters.

Key Differences — Fixed Spread vs Variable Spread

• Cost over time favours variable spreads for active traders. If you are placing 20+ trades per week during liquid sessions, the lower average variable spread adds up to significant savings versus a fixed spread. The maths heavily favours variable on high-volume trading across major pairs like AUD/USD and EUR/USD.
• Fixed spreads protect you around news events. If you trade through high-impact events such as US Non-Farm Payrolls or RBA decisions, a fixed spread removes the risk of your cost suddenly tripling. With a variable spread, slippage and spread widening can turn a planned low-cost trade into an expensive one very quickly.
• Predictability affects strategy planning. With a fixed spread, you always know your exact break-even point before entering a trade. With variable spreads, you need to factor in typical spread ranges and worst-case scenarios when calculating risk-to-reward ratios and placing your stop-loss levels.
• Account type and broker model matters for Australians. ASIC-licensed ECN brokers like IC Markets and Pepperstone offer raw variable spreads from 0.0 pips plus a small commission. Market makers offering fixed spreads, such as Plus500, build their profit into the wider spread with no separate commission. Neither model is inherently dishonest — both are ASIC-regulated — but the cost structure is very different.
• Scalping strategies are affected differently. Scalpers who trade multiple times per session during liquid hours almost always do better with variable spreads. However, scalpers who specifically trade news volatility sometimes prefer fixed spreads to lock in their entry cost before the spike occurs.

Which Is Better for Australian Traders?

For the majority of Australian retail traders, variable spreads cost less over time — and that is the clear recommendation here. If you trade during the Sydney, London, or New York sessions on major pairs, the lower average spread on an ECN account will reduce your trading costs significantly compared to a fixed spread broker.

If you are a beginner who trades occasionally and values simplicity → a fixed spread broker like Plus500 removes the guesswork from cost calculations while you learn. There are no nasty surprises from spread widening as you find your feet.

If you are an active day trader or scalper who trades liquid sessions → choose a variable spread ECN broker like IC Markets or Pepperstone. Review our IC Markets review for their current raw spread account details. Their raw accounts start from 0.0 pips on AUD/USD with a small per-lot commission, which is almost always cheaper than any fixed spread option at volume.

If you regularly trade around Australian or US economic news → consider keeping a fixed spread account specifically for those sessions, and a variable spread account for regular trading. Many ASIC brokers allow multiple accounts.

Whatever you choose, make sure your broker is ASIC-licensed. ASIC regulation means the broker must segregate client funds and meet strict capital requirements — critical protections for Australian retail traders.
