Forex Overnight Rollover Swaps Explained 2026: How to Calculate Swap Fees on USD, EUR, Gold and CFDs
Hold a forex or CFD position past the daily rollover and your broker applies a swap — sometimes paying you, sometimes charging you. On short-term scalps the swap is trivial. On a swing position held for a month, or on a $2,600+ gold position in the current 2026 rate environment, the swap can easily exceed the spread you paid to enter the trade, sometimes by an order of magnitude. Traders who check spreads obsessively and forget swap routinely overpay for overnight financing without noticing.
This guide explains swap from first principles: how it is calculated, how to read a broker’s swap table, how the Wednesday triple-swap rule works, how gold, indices and crypto CFDs differ from forex pairs, and how UZFX’s swap mechanics compare to typical retail broker behaviour. If you are a scalper who closes every position before the rollover, this article is useful background. If you hold any swing or position trade overnight, it is essential reading.

What Is a Swap?
A swap, also called rollover or overnight interest, is the interest charged or paid when a leveraged position is held past the daily market rollover. On the global forex market the rollover occurs at 17:00 New York time (EST) — equivalent to 22:00 UTC, and typically 00:00 server time on MetaTrader 4 and 5.
The mechanism behind swap is interest rate differentials. Every currency has a benchmark overnight interest rate set by its central bank. When you buy a currency pair, you are effectively buying one currency and selling another. Overnight, the interest rate differential between those two currencies either pays you (if the currency you hold pays more) or charges you (if the currency you hold pays less).
For non-forex CFDs — gold, silver, indices, stocks, energies, crypto — swap is a financing fee based on the broker’s cost of carry, not a two-way interest differential. That is why gold and index swaps are almost always negative on the buy side (you are borrowing money to hold the position).
How Is Swap Calculated?
The textbook formula for a forex pair is:
Swap = Position Notional × (Rate on Long Currency − Rate on Short Currency) ÷ 360 − Broker Adjustment
- Position Notional — the total value of the position, in the quote currency
- Rate on Long Currency — the overnight interest rate on the currency you are buying
- Rate on Short Currency — the overnight interest rate on the currency you are selling
- 360 — the money-market convention for annualising daily interest (brokers use 360, not 365, on most pairs)
- Broker Adjustment — a broker-defined spread that funds the broker’s financing cost and profit margin
Most brokers do not ask you to calculate this yourself. They publish the final value per standard lot per night in the instrument specifications inside the platform, typically labelled as Swap Long (for buy positions) and Swap Short (for sell positions). If the value is negative, you pay; if positive, you earn.
On MetaTrader 4 and MetaTrader 5, the same values appear in the Symbol Specifications window under the Symbol Info tab. The field names may vary slightly depending on the broker but the semantics are the same: Swap Long = rate applied when you hold a buy position overnight, Swap Short = rate applied when you hold a sell position overnight.
Reading the Swap Table
Every swap rate comes with two mandatory denominators: per standard lot and per night. Strip either one away and the figure stops meaning anything.
A typical retail swap table for 2026 (US-domiciled account, approximate values based on current rate environment) looks like this:
| Instrument | Long — per lot / night | Short — per lot / night |
|---|---|---|
| EUR/USD | −$8.90 | +$1.90 |
| GBP/USD | −$3.10 | −$4.20 |
| AUD/USD | −$1.95 | −$2.90 |
| USD/CAD | +$1.62 | −$5.81 |
| USD/JPY | +$4.33 | −$17.53 |
| XAU/USD (Gold) | −$67.90 | +$27.00 |
| US500 (S&P 500) | ≈ −$2.10 | ≈ −$2.10 |
A negative number costs you to hold; a positive one pays you. Triple swap is applied on Wednesday night for the weekend value date.
Notice a few patterns that recur across brokers:
- Major pairs with a USD quote usually show negative long swaps when the USD rate is above the quote currency’s rate. The current 2026 rate environment (USD rates still elevated after the 2026 Fed tightening cycle) makes most USD-quote longs negative.
- USD/JPY often shows a positive long swap and a negative short swap, because the Japanese rate is far below the US rate. Long USD/JPY means you are borrowing JPY (cheap) and lending USD (higher). You earn the difference.
- Gold long swaps are large negative numbers (typically −$30 to −$70 per lot per night) because gold carries a significant financing cost on top of the interest differential. This is the single most common source of overnight cost blow-up for retail traders.
- Index CFD swaps are almost always negative in both directions — index CFDs are financing fees, not interest rate differentials.
The Triple-Swap Wednesday Rule
The forex market settles spot transactions on a T+2 basis — a trade opened Monday settles Wednesday. Because interbank liquidity providers do not clear transactions on weekends, one weekday each week must carry the entire weekend’s financing. That day is almost always Wednesday at 17:00 EST / 00:00 server time.
Concretely:
| Trade Opened (Rollover) | Settlement Value Date | Swap Charged |
|---|---|---|
| Monday 17:00 EST | Wednesday | 1× (one day) |
| Tuesday 17:00 EST | Thursday | 1× |
| Wednesday 17:00 EST | Friday → Monday | 3× (three days) |
| Thursday 17:00 EST | Monday | 1× |
| Friday 17:00 EST | Tuesday | 1× |
If you hold one standard lot of XAU/USD long through Wednesday’s rollover with a broker-quoted swap of −$67.90 per night, the Wednesday charge is not −$67.90 — it is −$67.90 × 3 = −$203.70 in a single debit.
This has a practical implication for swing traders: if your entry trigger lands near Wednesday 16:55 EST, delaying execution until 17:01 EST can save you a triple-swap charge without materially altering your trade thesis. On 2.00 lots of gold, that 6-minute delay is worth roughly $400 to $600 in cash.
Swap on Gold (XAU/USD)
Gold is quoted against USD, so holding XAU/USD long overnight means you are effectively borrowing USD to fund the position. In the 2026 rate environment, that financing cost runs approximately 5.0% annualised, which translates to about $37 per night for a standard lot of 100 ounces at current gold prices in the interbank base — before broker adjustment.
Retail brokers typically layer a broker adjustment on top, so typical XAU/USD long swap figures in 2026 range from:
| Broker tier | Long swap per lot per night (approx.) |
|---|---|
| Institutional baseline | −$18.50 |
| Raw ECN | −$22.00 |
| Standard retail (B-book) | −$38.00 |
| Aggressive prop-style mark | −$52.00 |
That is roughly a 3× spread in cost between the most and least expensive brokers on the identical position. Over a 30-day hold of 1.00 lot, the gap can exceed $1,300 in cumulative swap. On swing positions, this dwarfs the initial spread.
Short gold positions often earn swap, because the short side is lending gold into a higher-yield USD market. This is why some carry-trade strategies pair short gold with a short gold swap credit. But those credits are broker-specific and can flip in a rate-change event.

Swap on Indices, Stocks and Crypto CFDs
For non-forex CFDs the calculation is simpler — there is no interest-rate differential, just a financing cost that the broker marks up from its own borrow rate.
- Index CFDs (S&P 500, Nasdaq 100, DAX, FTSE 100, Nikkei 225) typically carry a financing cost of approximately 5–6% annualised, applied to the position notional. The broker then marks up this rate by roughly 2–4 percentage points. A 1-contract S&P 500 CFD at $6,000 notional might cost roughly $2.10 per night long and short.
- Stock CFDs often carry higher markups (3–5 percentage points) because individual stock liquidity is thinner.
- Crypto CFDs behave differently from spot crypto: the broker lends the coin equivalent and charges overnight financing. Some brokers pass this straight through, others mark up by 2–4%. Crypto swaps are often negative in both directions and can be 3–5× higher than equivalent index CFDs.
- Energy CFDs (Brent Crude, WTI, Natural Gas) are typically negative long / positive short, reflecting the funding cost of holding oil inventories.
The exact numbers are always in your platform’s contract specifications. If your broker shows a swap of −$50 per lot per night on a 1-lot position, that is $50 per night, period — the underlying calculation is not something you need to reverse-engineer.
UZFX Swap Mechanics
UZFX is ASIC-regulated under AFSL 001291473 (UZFX Australia Pty Ltd). As an ASIC-regulated broker, UZFX is required to publish swap and rollover rates for every instrument in its platform’s contract specifications, and to keep those rates competitive with the interbank base rate.
Key features of UZFX swap mechanics:
- Swap rates are set on the broker’s Web Terminal, viewable per-instrument via the contract specification panel.
- Long and short swaps are quoted separately — the direction of your position determines which rate applies.
- Standard accounts apply a small broker adjustment over the base rate. On forex pairs this typically adds roughly 1–2 percentage points to the base interest differential.
- Islamic (swap-free) accounts are available on request for eligible clients, replacing overnight interest with a fixed daily or weekly administrative fee.
- Triple-swap Wednesday applies on the UZFX platform, following the standard global T+2 convention.
The exact swap figures for any given instrument should always be checked in the platform before opening a swing trade — swap rates change with underlying central bank rates, and a rate decision in the middle of a position changes the cost of holding.
The general pattern is that UZFX swap costs sit close to the interbank base rate plus a modest adjustment — comparable to Raw ECN-style pricing, and cheaper than the average Standard retail broker. For swing traders this matters: a month of gold holding at UZFX swap rates typically costs less than the same hold at a Standard retail broker, even before accounting for spread differences.
Position Sizing and Swap
Swap is often ignored in position sizing because it is small on a single day. Over a month of holding, though, it dominates.
For a monthly swing trade, the rule of thumb:
Monthly Swap Cost ≈ Swap per lot per night × lots × charged nights × triple-swap adjustment
Example: 0.50 lot XAU/USD long for 30 days, from a Monday:
- Regular weekday nights: 21 × 1× = 21
- Triple-swap Wednesdays: 4 × 3× = 12 (Wednesdays carry 3×)
- Charged nights total: 33
- Swap per lot per night: −$67.90
- Total: 0.50 × −$67.90 × 33 = ≈ −$1,120
That is the swap bill for a single $6,750 notional gold position held for one month — even before accounting for spread, movement, or margin usage. It is not unusual for this swap cost to exceed the trading profit of a “winning” swing trade held overnight.
Practical rules for swing traders:
- Check swap before entering. Look up the current swap rate in your platform, not a published table from three months ago.
- Never hold a large gold position overnight without factoring in the triple-swap Wednesday cost.
- Prefer short-position swaps when the base rate is in your favour. Long USD/JPY, short EUR/USD, and short XAU/USD often earn swap in the 2026 rate environment — but verify for the current month.
- Use an Islamic account if the swap cost is material to your strategy. A fixed daily fee of a few dollars is often cheaper than a variable swap of tens of dollars per night on gold.
- Never size a position on margin alone. Size on total monthly holding cost including swap, spread, and margin usage.
Swap-Free (Islamic) Accounts
A swap-free account, also called an Islamic account or Sharia-compliant account, charges no swap or rollover interest at all. It is designed for Muslim traders who require trading to be free of riba (interest-based finance).
Because the broker cannot charge interest-based swap, brokers that offer Islamic accounts typically substitute a flat daily or weekly administrative fee in place of the variable swap. This fee is fixed regardless of position size or direction, and is generally smaller than a typical long swap on gold or indices.
Common features of Islamic accounts:
- No overnight interest on forex pairs
- Flat daily or weekly fee (varies by broker and entity)
- Access to the same instrument universe as standard accounts
- Same leverage and spreads
- Available on request — most brokers require the client to declare Islamic account status during registration
- Not always available in all jurisdictions (regulatory restrictions vary)
Who should use an Islamic account? Primarily traders who require Sharia-compliant trading. But it is also worth considering for swing traders whose positions frequently cross rollover times on gold, indices or crypto — where the flat fee may be cheaper than variable swap in some scenarios.
UZFX offers an Islamic swap-free account option for eligible clients who request it during account opening.
Worked Example: A EUR/USD Swing Trade
Let’s walk through a concrete example using UZFX-style retail pricing.
Setup:
- Position: 1.00 lot long EUR/USD
- Entry: 1.0850
- Direction: Buy EUR, sell USD
- Account currency: USD
- Current UZFX EUR/USD long swap: approximately −$8.90 per lot per night
- Hold period: 30 days from a Monday
Swap calculation:
- Regular weekday nights: 21 × 1 = 21
- Triple-swap Wednesdays: 4 × 3 = 12
- Charged nights: 33
- Total swap: 1.00 × (−$8.90) × 33 = −$293.70
The trader pays $293.70 in swap for a 30-day hold of a 1-lot EUR/USD position — before any price movement.
Comparison with UZFX Islamic account:
- Daily flat fee (typical): $1.50
- 30 days: 30 × $1.50 = $45
- Savings: $293.70 − $45 = $248.70
For a swing trader holding EUR/USD long for a month in the 2026 rate environment, the Islamic account is significantly cheaper.
Frequently Asked Questions
What time does swap get charged? At the daily market rollover — typically 17:00 New York time (EST), 22:00 UTC, and 00:00 server time on most MT4/MT5 setups. Any position still open at that moment is charged the swap for that night.
Does the swap rate change every day? Yes. Swap rates are recalculated by brokers when central bank rates change, and adjusted continuously to reflect current liquidity costs. A swap rate published today may not be the same rate in three months.
Can I avoid paying swap entirely? Yes — if you close the position before the daily rollover (for scalpers), or if you use a swap-free Islamic account. Otherwise, swap is unavoidable on any held position.
Why is the swap so high on gold? Gold CFDs carry a large financing cost on top of the interest rate differential, because gold is not a yield-bearing asset. Brokers charge a funding cost that reflects the base rate plus a broker adjustment, and on a $2,600+ gold position that cost runs $30 to $70 per lot per night in the 2026 rate environment.
Does UZFX charge triple swap on Wednesday? Yes. UZFX follows the standard T+2 spot settlement convention. Positions still open at the Wednesday rollover are charged three days of swap at once, in addition to the regular Monday–Friday nightly charges.
What is the difference between swap and rollover? Nothing. “Swap” and “rollover” are two names for the same thing. Some brokers use “swap,” others use “rollover,” some use both interchangeably. The mechanism is identical.
Is swap the only overnight cost on a held position? Yes for forex and most CFDs. Some brokers charge an additional inactivity fee on dormant accounts, but active trading accounts are only charged swap overnight. UZFX does not charge inactivity fees.
Final Verdict
Swap is the second-most important cost in leveraged trading after spread — and the most ignored. On a 30-day swing hold, the cumulative swap can easily exceed the spread you paid to enter, particularly on gold, indices and crypto. The triple-swap Wednesday rule amplifies this further, because a single Wednesday rollover on a held position can add three days of financing cost to a single nightly debit.
Best practices:
- Always check the current swap rate in your platform before opening a swing trade.
- Factor swap into position sizing — a “1% risk” trade that ignores swap can become a 5%+ loss in a month.
- Never hold a large gold position overnight without calculating the triple-swap cost.
- Consider a swap-free Islamic account if overnight holds are central to your strategy and the base swap cost is material.
- Time entries to avoid the Wednesday rollover when the position is small and the timing is flexible.
- Monitor swap credits — in the 2026 rate environment, USD/JPY long and short gold short often earn swap. These can add to your profit rather than drain it.
On UZFX — an ASIC-regulated broker under AFSL 001291473 — swap rates are set on the interbank base rate plus a modest adjustment, comparable to Raw ECN-style pricing. Swing traders who need overnight holds on gold, indices or a large EUR/USD position should verify the current swap rates in the UZFX Web Terminal before committing capital. Combined with UZFX’s $10 minimum deposit, zero-commission spread-only pricing, and Islamic account option, the total cost of holding a position at UZFX is typically lower than at Standard retail brokers — but that only matters if you actually check the swap before you enter.
