What Is a Funding Rate? How Perpetual Futures Charge Longs and Shorts

A funding rate is a periodic transfer between long and short positions in a perpetual future, designed to keep the contract price near its reference market. It is not a fixed entry fee: when the displayed rate is positive, longs generally pay shorts; when it is negative, shorts generally pay longs, with the actual amount depending on the live rate, position notional, and settlement condition.

How funding moves between longs and shorts

A perpetual future has no expiry, so the market uses funding to discourage the contract from staying far from its reference price. Strong demand for longs can coincide with a positive rate, while stronger demand for shorts can coincide with a negative rate. That describes a funding transfer at a particular time; it is not proof that price must rise, fall, or reverse.

WEEX’s Taiwan BTC/USDT perpetual page displayed a funding-rate field and a settlement countdown on September 17, 2026. The field changes with the contract and market. Read the value currently shown on the page rather than turning one percentage into a long-term condition. WEEX’s contract-formulas guide should be read with the current product rules.

How the charge affects a position

Funding is generally based on a position’s notional value and the live rate, not simply on the margin deposited. Therefore, the direction, size, and whether the position is held at the settlement point can affect the account result. In a positive-rate environment, a long trader should include funding in the cost of holding; in a negative-rate environment, a short trader should not assume a fixed income because the rate can change.

Funding is separate from trading fees, realized profit and loss, and slippage. A favorable price move can still be reduced by fees and funding, while a nearly flat price can still produce a changed net result. When reviewing a position, keep direction, notional value, funding, entry and exit execution, and available margin as separate fields.

A beginner’s funding checklist

1. Select the correct perpetual pair and confirm the displayed funding rate, settlement countdown, and position direction.
2. Put the rate into the context of your intended holding period and position size instead of looking only at whether it is positive or negative.
3. Include funding with fees, slippage, price movement, and margin changes. A funding transfer is not a guaranteed return.
4. Set an exit condition and check the position record around settlement. Do not ignore liquidation distance simply to wait for a possible payment.
5. Re-read the live product rules when the interface shows maintenance, trading restrictions, or a change to the contract’s parameters.

Funding is not a stand-alone signal

A high positive rate can reflect crowded long demand or a temporary imbalance; a negative rate cannot independently prove a reversal. Funding, open interest, order-book depth, and price behavior should be considered in one risk framework. Claims that a trader can earn a stable return merely by collecting funding ignore direction, liquidation, execution, and liquidity risks.

Leverage magnifies a price loss and can trigger liquidation before the next funding event. Check the current terms on the WEEX futures page before deciding whether to act. If your goal is to buy and hold an asset without a perpetual position, compare the BTC/USDT spot page; spot still carries price, custody, and transfer risk.

Reading a funding field responsibly

The sign tells you the usual direction of the transfer, but it does not tell you the size of the eventual account change by itself. A small rate applied to a large notional position can matter, while a large-looking rate on a very small position may have a different effect. Check the position notional and the product’s displayed calculation rather than comparing percentages across unrelated pairs.

The countdown is also a condition to observe, not a promise that the rate will remain unchanged until settlement. The rate may update, the position may be resized, and a close may occur before the event. Keep a record of the rate and position details shown when you make a decision, then review the final position record afterward.

Keep the account calculation visible

When you open a position, record the displayed rate, notional value, direction, and settlement countdown. After the event, compare the funding line with the position history rather than estimating from memory. This is especially useful when a position was resized, partially closed, or held across more than one displayed update.

Do not compare a funding percentage from one contract directly with another without checking each product’s notional convention and settlement rule. The same sign can have a different practical effect when position size, price, and account currency differ.

Common questions

Is funding a fee kept by the exchange?

It is generally a transfer between long and short positions rather than the same item as a trading fee. Read the position record and fee page separately because the calculations and recipients differ.

Does a positive funding rate mean price must fall?

No. It reflects a funding condition at a particular time and cannot, by itself, forecast price direction or a turning point.

Do I need to watch funding without leverage?

If you do not hold a perpetual position, you do not pay or receive funding as a contract position. Spot and futures are different products, so confirm what the account actually holds.
