Who funds my leveraged futures trade, and why would an exchange do that?

01So who actually gives you the money?

Say you set leverage to 10x and open a position worth 1,000 USDT while you have 100 USDT in your futures wallet. Not a single dollar moves from the exchange to you. Your 100 USDT stays where it is, and the exchange just marks it as unavailable for anything else until the trade closes — that reserved part is your margin, a deposit, the way a rental shop holds a deposit while you have the bike.

The trade itself is an agreement about price between you and whoever took the opposite side. If bitcoin rises, money moves from the people who are short into your account; if it falls, it moves out of yours into theirs. That is why nobody had to hand you 900 USDT — no 1,000 USDT of bitcoin is ever bought, delivered or stored anywhere, and all that gets settled is the price difference. If you want the longer version of that flow, we wrote it out in where futures profit actually comes from.

This is the real difference from margin trading on spot, where the exchange genuinely does lend you coins or cash, you genuinely do buy the asset, and interest runs for as long as you hold it — on Binance, margin interest accrues hourly. On futures there is no borrowing line and no interest. The regular holding cost on a perpetual contract is funding, and that payment goes between longs and shorts; the exchange does not take it.

02What 100 USDT at 10x looks like inside your account

Here is the same trade with numbers you can check on screen. With an illustrative bitcoin price of 83,500, a 1,000 USDT position is about 0.012 BTC. Your wallet shows 100 USDT, your position shows 1,000 USDT of bitcoin, and the margin field shows that your 100 USDT is tied to it. A 1% move in your favor is 10 USDT — small against the position, 10% against your deposit. A 1% move against you is exactly the same number with a minus sign.

The fee is charged on the 1,000, not on the 100. At Binance's base level for USDⓈ-M futures that is 0.05% as a taker, so roughly 0.50 USDT to get in and 0.50 USDT to get out — about 1 USDT for the round trip. The position size is comfortably above the minimum, too: on Binance the smallest bitcoin position is 0.001 BTC, which at that price is around 83.5 USDT of position value.

The diagram uses round numbers. Your own liquidation price will be a bit different, and the exchange shows it on the position once it is open — look at that one. It shifts with the maintenance margin required for your position size, your fees, your margin mode and anything else open in the account. If the leverage number itself is still fuzzy, the basics are in what leverage is — this page is only about where the money sits.

03Why would an exchange let you do this?

Because the fee follows the size of the position. Your 100 USDT traded on spot with no leverage pays a fee on 100 USDT. The same 100 USDT behind a 1,000 USDT futures position pays a fee on 1,000 — ten times more for the exchange, out of the same money in your pocket. Binance's published USDⓈ-M rates at the base level are 0.02% for a resting limit order that waits in the book and 0.05% when you take the price that is already there, a little lower if you pay fees in BNB.

That is the whole business model: the exchange earns on the size of every trade, not on lending you anything, and it does that across an enormous number of accounts — Binance reports more than 333 million users on its main platform. The easiest way to see your own numbers is to open a Binance Futures account and type a small size into the order window, which shows you the margin and the fee for exactly that size.

04How the exchange protects itself from your losses

Since no one lent you money, the exchange's worry is different: it needs your side of a losing trade to be paid to the winner. That is what maintenance margin is for. Once your deposit has shrunk to the minimum the contract requires, the exchange closes the position itself — this is liquidation, and it is triggered on the mark price, a fair price derived from an index, not on the last random trade printed on the chart.

Sometimes the market moves so fast that the position is closed at a price that still leaves a shortfall. The exchange's insurance fund covers that as far as it can; when it cannot, Binance closes a profitable position on the other side instead, at the price where the losing one had run out of margin. That is auto-deleveraging — rare, out of your hands, and explained here: why a position gets closed by ADL.

05What you actually risk

You risk the margin behind the position, plus the fees and funding while it is open. There is no repayment schedule, nothing to pay back afterwards, and no interest clock running. What does exist is a price level where the exchange closes the trade for you. So the thing to decide carefully is how much money you put behind the trade.

Two settings do most of the work. Isolated margin ties the position to the margin you assigned to it, so a bad trade on one coin does not reach across the rest of your balance, while cross margin links everything in the account together. And a stop-loss placed when you open the trade closes it long before the exchange has to.
