Forex swap rates determine the overnight charge or credit that can apply when you hold a currency position past your broker’s daily cut-off. The amount depends on the exact trade and account, and a credit is never guaranteed.
I wouldn’t judge an account by its advertised spread alone. Financing can change the cost of a position held for several days, so the broker’s terms matter alongside the product you trade.
Key Takeaways
- A forex swap is an overnight adjustment that may be deducted from your account or credited to it.
- Long and short positions can have different rates, even for the same currency pair.
- Brokers use their own cut-off times and calculation methods. Some apply larger adjustments for non-trading days.
- Position size, account currency and holding period can affect the amount you pay or receive.
- Swap-free accounts may have other charges, and regulatory protections differ by jurisdiction and client classification.
Forex Swap Rates Explained: The Cost of Holding Positions Overnight
A forex swap, also called rollover or overnight financing, is an adjustment for carrying a position beyond the broker’s daily cut-off. Depending on the contract, it can reduce your balance, add a credit or appear through another adjustment to the position.
The product matters. A currency CFD is a contract based on price movements, while a spot forex arrangement can use different settlement and rollover terms. Our guide to the difference between CFD trading and forex explains why those distinctions matter.
Why long and short positions can have different swap rates
A currency pair combines two currencies with different interest rates. Those differences can inform overnight pricing, but the broker’s calculation may also include a markup and other adjustments.
A long position and a short position in the same pair can therefore have different rates. One could receive a credit while the other incurs a charge, or both could incur charges. I wouldn’t predict the actual amount by comparing central bank rates alone.
What the broker’s rollover time means for your position
The cut-off is the time a broker uses to decide whether an open position enters its rollover process. It isn’t necessarily midnight where you live, and a short position held across the cut-off can be treated differently from a longer position closed beforehand.
For example, FOREX.com’s US rollover page describes a 5 p.m. Eastern Time cut-off. That US schedule doesn’t establish the terms for a European account. Broker server times, daylight-saving changes and non-trading-day adjustments can affect when a particular position rolls over.
How forex overnight financing is calculated
The amount can depend on the position’s notional value, meaning its full market exposure rather than only the margin deposited. Direction, the applicable rate, the number of financing days and currency conversion can also matter.
Brokers express rates in different units, including points or annual percentages. Contract size and the relevant currency determine how those figures translate into an account adjustment. There is no single calculation that fits every product.
A simple example of a charge or credit
Consider a hypothetical leveraged position with a £10,000 notional value. Assume the broker applies a fixed 7.3% annual financing charge, uses a 365-day basis and calculates the charge in pounds.
Under those assumptions, one financing day costs £2: £10,000 multiplied by 7.3%, then divided by 365. Five financing days would cost £10, excluding spreads, commissions and any other charges.
This is arithmetic, not a live broker quote. A real rate or position value could change, and a broker might use a different method. A credit would need its own applicable rate; it isn’t automatically the opposite of the charge.
Why a triple rollover adjustment may appear
Some brokers apply an adjustment covering three financing days at one rollover to account for non-trading days. The larger entry can be a debit or a credit, depending on the applicable rate.
Equiti’s explanatory material describes a Wednesday adjustment for certain currency pairs with a two-business-day settlement convention. That example doesn’t make Wednesday a universal rule. The applicable day and calculation depend on the broker and instrument.
How swap rates affect your total trading cost
Overnight financing accumulates separately from a position’s price movement. A trade can move in your favour and still incur a financing charge; it can also lose money despite receiving a credit.
I include financing alongside the spread, which is the gap between buy and sell prices, and any commission. Currency conversion can add a cost too. Slippage, the difference between an expected price and the actual execution price, can improve or worsen the result.
A narrow advertised spread doesn’t establish the lowest total cost. Our guide to comparing forex broker fees covers the wider calculation.
Check both long and short rates, plus account-specific terms
For a useful comparison, use the same currency pair, position size, account currency and expected holding period. Match the account type and client classification too, since conditions can differ between them.
Compare equivalent spread figures: a minimum spread from one account isn’t the same as a typical spread from another. Commission may be quoted per side or for the complete opening and closing transaction. The applicable legal entity and its contract specifications matter as much as the broker’s brand name.
What swap-free accounts change, and what they do not
A swap-free account changes the treatment of standard overnight financing. It doesn’t necessarily remove every cost of holding a trade.
Some terms provide for administration or holding charges, eligibility conditions or time limits. Spreads, commissions, conversion costs and market risk can remain. I assess the full charging structure rather than treating the account label as proof that a position is free to hold.
How to check a broker’s overnight charges before trading
The most useful comparison starts with the documents for the account you would open, rather than a generic pricing page. Rates and terms can change, so keep a dated copy of the relevant schedule.
Find the right rate and charging schedule
I would work through these checks before holding a position beyond rollover:
- Find the financing table and contract specification for the broker’s relevant legal entity and account.
- Match the exact symbol and trade direction to the quoted long or short rate.
- Identify the rate unit, contract size and currency used for the calculation.
- Note the cut-off time and any adjustments for weekends or holidays.
- Add applicable conversion, commission and other account charges to the comparison.
A rate shown in points isn’t necessarily a cash amount. You need the contract details to translate it into the effect on your position.
Keep European rules and protections in context
Regulatory protections are separate from the broker’s financing schedule. The UK, EU, EEA countries and Switzerland don’t all operate under one identical set of rules.
For example, the FCA’s UK retail CFD restrictions include limits on leverage, margin close-out requirements and negative-balance protection. ESMA’s original EU retail CFD measures included similar categories of protection, followed by national measures.
These protections depend on the product, jurisdiction and client classification. Authorisation doesn’t prevent trading losses, guarantee fair execution or establish that every overseas customer receives the same protection.
Frequently Asked Questions
Can a trade held for a few minutes incur a swap?
It can if the position is open across the broker’s rollover cut-off and the applicable terms impose an adjustment. The clock time matters more than whether the trade has been open for a full calendar day. Conversely, a position closed before the cut-off may avoid that rollover adjustment.
Does financing apply if the currency price doesn’t move?
It can. An overnight adjustment concerns the cost or credit associated with carrying the position, not whether the market price changed. A stationary price therefore doesn’t cancel an applicable charge, although the final trading result can also include the spread and commission.
Do opposite positions cancel each other’s swap charges?
Not necessarily. A broker may calculate financing separately for each open position, with different rates for the long and short sides. Even if the positions offset some market exposure, their combined financing can still be a cost. The treatment depends on the account and contract.
Can a stop-loss prevent an overnight charge?
A stop-loss is an order intended to close a position when a specified trigger is reached. It doesn’t prevent financing while the position remains open across rollover. Execution can also differ from the requested level, particularly during gaps or volatile markets.
Where can an overnight adjustment appear?
It may appear in the platform’s transaction history or account statement as a swap, rollover or financing entry. Some product structures can reflect rollover through an adjustment to the position instead. The statement and contract terms should explain how the broker records it.
Compare the Full Cost of Holding a Position
The cost of an overnight forex position depends on the broker, instrument, direction, account and time held. A credit is possible, but it isn’t assured, and financing can add up even when the market moves in your favour.
I would compare total trading costs for the same position before choosing an account. Use the applicable official terms, and remember that understanding a charge doesn’t remove the risk of loss.
