تمويل التبييت ورسوم السواب: تكلفة الاحتفاظ بالمركز

Swap is the least-understood line on a trading statement, and the easiest to derive. Hold a currency position overnight and you are, in effect, lending one currency and borrowing another — so each night you are charged or paid the difference between their interest rates, adjusted by your broker's financing terms. This sheet derives that number, explains the 5pm New York ritual and triple-swap Wednesday, and shows how holding time quietly becomes the largest cost of a trade.

Why holding overnight costs or pays: the differential, derived

Buying EUR/USD means holding euros and owing dollars. Money held earns its currency's overnight interest rate; money owed pays it. So a long EUR/USD position earns the euro rate and pays the dollar rate, every day it exists. If the euro rate is lower than the dollar rate — as it has often been — the position loses the difference nightly. A short position points the same arrow the other way. This is the entire mechanism; everything else is bookkeeping and markup.

The broker then adds its financing adjustment, because the borrowing that funds your leveraged position is arranged through it. The adjustment works against you on both sides: it makes the paying side pay a little more and the receiving side receive a little less. That is why the long and short ▲swap rates on the same pair never mirror each other exactly — the gap between them is the financing cost, and it is one of the prices a broker actually charges you.

Where do the rates come from? Each currency has an overnight interest rate anchored by its central bank — the rate at which banks lend that currency to each other for a day. Those rates are public, they move when central banks move, and the gap between any two of them is the raw material of every swap quote. This is why swap rates are not fixed properties of a pair: a central-bank decision on either side repositions the differential, and your nightly charge with it.

Read the worked rows twice. At $10 per pip, the long side is paying about one pip per night just to exist, while the short side receives less than half of what the raw differential suggests — the financing adjustment absorbed the rest. The rates above are illustrative, not quotes; the structure is what matters, and it is the structure you will verify against the published schedule at the end of this sheet.

Rollover at 5pm New York: what actually happens

Spot FX trades settle two business days after the trade. A position you keep open past the daily cut-off is therefore ▲rolled over: the settlement date moves one day forward, and the financing for that extra day — the swap — is applied to your account. The industry's cut-off is 5pm New York time (21:00 or 22:00 UTC depending on daylight saving), the formal end of the global trading day.

You will not see your position close and reopen; modern platforms post the swap as a separate line while the position runs on. Two practical notes attach to the hour itself. First, the swap is charged on positions open at the cut-off, even if opened a minute before — there is no pro-rating. Second, the minutes around rollover are the day's thinnest, with wide spreads, because liquidity providers step back while their books close. ▲Overnight financing is unavoidable for a position you intend to keep; trading through the rollover hour itself is a cost you can simply not pay.

The mirror image is just as useful: a position opened and closed inside the same trading day never meets the cut-off and never pays swap. Day traders can read this entire sheet as background. And for completeness — some brokers offer swap-free account types, typically replacing the nightly swap with fixed administration fees after a grace period. The label changes; the financing cost is relocated, not removed. Read such terms with the same arithmetic you are using here.

Triple-swap Wednesday and the weekend, explained once

The weekend never escapes financing — it is just billed in advance. Follow the settlement arithmetic: a position rolled on Wednesday night moves its settlement from Friday to the next business day, which is Monday. That single roll spans three calendar days — Saturday, Sunday, Monday — so Wednesday's swap is charged at three times the nightly rate. Hold through a Wednesday rollover and the statement shows one entry worth three.

Edge cases to expect rather than be surprised by: some instruments — many index and commodity CFDs — apply the triple charge on Friday instead, because their financing follows the calendar rather than spot settlement; and public holidays in either currency's home market shift settlement dates, producing occasional double or quadruple days. The published swap schedule states which day carries the multiple for each instrument. None of this changes the total — seven days of financing per week — only when it lands.

Index and share CFDs: dividend adjustments, both directions

Overnight costs follow a CFD onto other markets, with one extra line. When a company in an index pays a dividend, the index drops by the dividend's weight — mechanically, not because of sentiment. Since CFD holders own no shares and receive no dividends, the broker posts a ▲dividend adjustment: long positions are credited roughly what the drop took from them, short positions are debited roughly what the drop handed them.

Neither direction is a gift or a fine — the adjustment exists to cancel a price move that carries no information, leaving you exposed only to the market's real movement. What is not neutral is the financing on these instruments: equity CFD financing rates are typically built on a benchmark rate plus a markup paid by longs (and partly received by shorts), so the long side of an index CFD held for months pays a materially higher annualized cost than the headline spread ever suggested.

One trade, two horizons: a day versus a month

Now assemble the full bill for the worked position — long one standard lot of EUR/USD, spread 0.7 pips, the illustrative swap rates from above — held for one night and for thirty calendar nights:

The month-long version of this trade starts 30 pips behind: the market must move 30 pips in your favor before the position reaches break-even. The symmetry deserves stating plainly — a favorable 100-pip move nets you $1,000 minus $301 of costs, while the same move against you costs $1,000 plus the same $301. Financing never takes a side; it accrues against the position whichever way price goes.

Two honest consequences follow. For ▲swing trading, swap is not a footnote but a planning input: a positive-swap direction lengthens your runway, a negative-swap direction shortens it, and a trade thesis that needs months must clear a cost hurdle a day trade never sees. And yes — collecting the differential deliberately is a known strategy, the carry trade. It collects small credits while remaining fully exposed to exchange-rate moves that can erase months of them in a day; it is covered honestly in its own sheet.
