Swap and Overnight Funding Explained

Trading a CFD means you never actually take ownership of the asset you are trading. You are speculating on the price movement. Because of that, positions held open past a certain time are subject to something called swap, also known as overnight funding.

This is a fee or credit applied to your account to reflect the cost of keeping your position open overnight. Think of it as the interest you pay (or earn) for borrowing the capital to hold that trade. For a trader in Australia using Plus500, which operates under an ASIC licence, the mechanics of swap are a core cost of doing business.

If you open and close a trade within the same day, you avoid swap entirely. This is often called intraday trading. Hold a position past the daily cut-off time, usually 5:00 PM New York time, and the swap charge or credit will be applied to your account.

How Swap Is Calculated

The swap amount is not a fixed fee. It is derived from the interest rate differential between the two currencies or assets involved in your trade. Plus500, like most brokers, also adds a small administrative markup to this rate.

For a forex pair like USD/CAD, you are essentially borrowing one currency to buy another. The difference in the central bank interest rates of the Eurozone and the US is the base for the swap calculation. Because this rate changes, the daily swap cost will fluctuate.

On the Plus500 platform, this is stated as a value in the "Swap" column of the trade ticket before you open a position. It shows the cost per unit of your position size. You should review this number before entering any trade you plan to hold for more than a day.

Swap Fees and ASIC Regulation

Australian clients are served by Plus500AU Pty Ltd, ACN 153 301 681, which holds Australian Financial Services Licence number 417727 issued by the Australian Securities and Investments Commission (ASIC). ASIC has implemented strict product intervention orders that limit the leverage available to retail clients, which directly impacts the size of your position.

ASIC rules for retail clients cap leverage at 30:1 for major pairs, which includes USD/CAD. This is significantly lower than what many offshore brokers advertise. The lower leverage means your position size is smaller relative to your deposit. A smaller position size results in a smaller absolute swap fee, even if the underlying rate is similar.

The swap fee itself is still calculated on the full notional value of the trade, but your ability to open a large position with a small margin is heavily constrained by these ASIC caps.

When the Fee Triples: The Wednesday Effect

There is a well-known quirk in forex and CFD trading that catches many beginners off guard. If you hold a position open through Wednesday night, the swap fee is charged at three times the normal rate.

This is because swap is calculated on a T+2 settlement basis. If you hold a position on Wednesday, you are effectively holding it over the weekend, when markets are closed. The fee for Saturday and Sunday is bundled into the single Wednesday charge.

On the Plus500 platform, you will see the standard swap rate listed, but on Wednesday the actual charge applied will be roughly the listed rate multiplied by three. This applies to your account in AUD. A position opened on Thursday and held for one night will incur a single day's swap.

What's the Actual Cost in AUD

It is difficult to give a blanket number for swap because it moves with global interest rates. However, you can see the effect clearly. If you were to buy USD/CAD, you might earn a positive swap in some economic cycles or pay a small daily charge in others. For a gold trade, the cost is often a negative swap, meaning you pay a fee every night.

The key is to check the "Swap" field in the deal ticket on the Plus500 WebTrader or mobile app. It shows the cost in AUD for a position of that size. For example, a swap of -0.15 AUD with a 10,000 unit position means you pay 0.15 AUD each night you hold the trade.

Swap vs. Commission

Plus500 markets itself as commission-free. There is no separate broker commission charged per trade. The cost is built into the spread, which is the difference between the buy and sell price.

This is where your true cost of trading lies. A wider spread means you start a trade at a slight disadvantage. For short-term trades, the spread matters more than the swap. For longer-term trades, the swap fee accumulates and can become the dominant cost.

Notice that swap is not the only ongoing cost. The inactivity fee can also apply, so you should close or log in regularly to avoid it.

Issues Around Holding Positions

The most significant issue for a new trader is underestimating how quickly swap fees compound. A trade held for several weeks can accrue more in funding costs than the profit from the price move itself. This is especially true with less volatile instruments like major forex pairs.

Swap is charged on the full size of your position. With a longer-term trade, a negative swap of -0.5 AUD per night becomes -15 AUD over 30 days. Your trade needs to move enough to cover this before you see a profit.

Plus500 does not advertise a dedicated Islamic swap-free account for Australian clients. If you require a swap-free account for religious reasons, you would need to contact support to see if an accommodation can be made.

How to Minimise Swap Costs

If you want to avoid swap, your primary strategy is to close your trades before the daily cut-off time. This is known as day trading. For positions you want to hold for weeks, you are exposed to swap regardless.

You can also look at the direction of your trade. Some brokers pay you a positive swap if you are on the right side of the interest rate differential. For example, if you are long a currency with a high interest rate and short a currency with a low rate, you might earn interest. However, the price movement is the primary driver of your profit or loss, and swap is a secondary factor that can either slightly help or slightly hurt your account balance.

Swap Charges for Different Assets

The swap rate is not uniform. The table below shows typical ranges you might see on the Plus500 platform for different asset classes. These are examples, not fixed quotes, because the rates change with market conditions.

Crypto and commodities tend to have the most expensive negative swap rates. This makes a compelling case for keeping positions in these assets very short-term if you are trading them.

Costs Beyond the Swap

Swap is not the only factor to watch. With the ASIC-regulated entity, you have negative balance protection. This means you cannot lose more money than you have deposited in your account, even if the market gaps and your position goes deeply negative.

This protection is a direct result of ASIC regulation and is a major advantage over some offshore brokers that do not offer this guarantee. The trade-off is that you have lower leverage limits. But this lower leverage also reduces the size of your daily swap charge.

On the platform side, Plus500 uses its own proprietary WebTrader. You will not find MetaTrader 4 or MetaTrader 5. This closed system means no expert advisors or third-party algorithms. It limits the trading costs to just spread and swap, with no platform fees.

For a new trader, the ASIC leverage cap is a safety measure. A lower maximum position size means a smaller potential swap fee and a smaller potential loss. Use the demo account to get comfortable with how swap is calculated before risking real capital.

Final Thoughts on Swap

Swap is a necessary cost of leveraged trading. It is not a fee invented by Plus500; it is the underlying cost of holding a leveraged position.

The practical takeaway for an Australian trader is to know the swap number before you open a position. The Plus500 platform shows it clearly. If you are a short-term trader, swap should be a minor concern. If you are a swing trader holding positions for weeks, swap can be a deciding factor between a profitable and an unprofitable trade.

Calculate your swap exposure, especially for Wednesday night, and factor it into your trading plan. For those who trade on lower leverage or close positions daily, Plus500 remains a low-cost choice with strong ASIC oversight and negative balance protection.
