Overnight Financing: What You Pay to Hold

The short answer

Overnight financing is a daily charge for holding a leveraged position past the broker’s cut-off, calculated on the full position size rather than on your margin. It is the only cost here that grows with time rather than with activity, which makes it decisive for long holds and irrelevant for intraday ones.

Most trading costs are paid at the edges: something on the way in, something on the way out. Overnight financing is different. It is paid for as long as you are there, which makes it the only cost on this site that is a function of time rather than of activity.

What is actually being charged

A leveraged position is a position larger than the money you put up. The difference has to come from somewhere, and the charge is for that difference.

The crucial detail, and the one most often missed: financing is calculated on the full value of the position, not on your margin. Someone holding a position many times larger than their deposit is being financed on the whole thing, nightly. That is the mechanism by which leverage converts into a running cost, and it is why a modest-looking daily rate on a large notional is not modest.

It is applied at a cut-off time set by the broker, not at midnight in your timezone, and positions open across that moment are charged. A position opened and closed within the same session never meets it at all.

Why it can be a credit

Depending on the instrument and the direction, financing can go the other way and pay you. This is real, and it is a poor reason to do anything.

A position that pays to hold still carries every other cost on the ledger, and still carries the risk that the price moves against you by more than any accrual. Choosing a position because it pays to hold is choosing a trade for its smallest term. Note it, budget for it, and let the decision rest on the rest of the reasoning.

Rates also change. They are set by the broker, revised, and not guaranteed to stay on the same side of zero.

The compounding is where it bites

Because the charge repeats nightly, the arithmetic is unlike anything else on this site.

A spread is paid twice: once in, once out. It does not care whether the position lasted eleven seconds or eleven months. Financing cares about nothing else.

Hold for a day and it is usually trivial against the spread. Hold for a week and it is comparable. Hold for a quarter and it can be several times the spread and commission combined, quietly, without ever appearing as a line item that feels like a trade.

This is the reason a position can be directionally right and still finish behind. Nothing went wrong with the analysis; the cost of being there for that long was never put into the plan.

The practical consequence: if a strategy involves holding positions for weeks, financing is not a detail at the bottom of the cost stack. It is probably the largest single component, and it should be estimated before the position is opened rather than discovered afterwards.

Where to find your actual rate

We are not going to publish a financing rate. They vary by broker, by instrument, by direction and over time, and a figure quoted here would be wrong for most readers immediately.

Every broker publishes its own, usually under "swaps", "overnight funding" or "financing" in the contract specifications rather than on the page advertising spreads. The things worth establishing:

• Whether the rate is quoted per night or annualised
• Whether it differs for long and short
• Which day carries the multiple-day charge — brokers typically charge several days' financing on one weekday to cover the weekend
• What time the cut-off is, in your timezone

That weekend point catches people out. A position held across the relevant day is charged for days nobody traded.

Leverage, and why the charge got the attention it did

Financing exists because of leverage, and the retail availability of leverage has been the subject of formal regulatory intervention.

In 2018 the European Securities and Markets Authority adopted a decision temporarily restricting the marketing, distribution and sale of contracts for differences to retail clients, including specific leverage limits depending on the nature of the underlying, and a standardised risk warning showing the percentage of retail accounts losing money with each firm. That measure was time-limited, was subsequently renewed, and its substance was later taken into national rules.

The relevant point for this page is narrow. Leverage limits change the size of position a retail client can take, and financing is charged on position size. The two are directly connected, and the restriction is a reminder that the cost of holding a leveraged position was considered significant enough to regulate how much leverage could be offered in the first place.

It changed nothing about the mechanism. The charge is still nightly, still on the full notional, and still the one cost that grows while you do nothing at all.

Where this sits

Financing is one item in the whole cost stack, and the one that most often reorders it — see how costs change with your style. The charges it is most often confused with are in the costs nobody quotes.
