What Is Funding Rate? The Cost That Keeps Perpetual Futures Anchored
The funding rate is a small, periodic payment exchanged directly between long and short traders in perpetual futures. It exists to keep the perpetual contract's price tethered to the underlying spot price. Because perpetual futures never expire, the funding rate is the mechanism that stops them drifting away from reality — and, quietly, it is a running cost or income on every position you hold.
How Funding Rate Works
A perpetual future has no expiry date, so there is no settlement moment to force its price back in line with spot. The funding rate solves this. At fixed intervals (commonly every few hours), traders on one side pay traders on the other:
- When the funding rate is positive — the perpetual is trading above spot, so longs pay shorts. This nudges longs to close and shorts to open, pulling the price down toward spot.
- When the funding rate is negative — the perpetual is trading below spot, so shorts pay longs, nudging the price up.
A worked example: you hold a 1,000 USDT long position and the funding rate for the period is +0.01%. You pay 0.10 USDT (0.01% of 1,000) to the shorts for that interval. Small per period — but it repeats every interval you hold the position, and in strongly one-sided markets the rate can be much larger.
Note that funding is charged on your position size, not your margin. With leverage, a position much larger than your collateral means funding costs are larger relative to your deposit than they first appear.
Why It Matters to a Trader
- It is a real, recurring cost (or income). Holding a long through many positive-funding periods steadily erodes your balance even if the price does not move. The reverse can pay you.
- It is a sentiment signal. Persistently high positive funding means the market is crowded long (many leveraged buyers) — a condition that can precede sharp downside as those positions unwind.
- It shapes holding strategy. Funding is one reason perpetual futures suit shorter-term positions more comfortably than long, passive holding.
The Risk Section — Read This Carefully
- Funding compounds over time. A rate that looks tiny per interval becomes significant across days of holding, especially on a leveraged position sized far above your margin.
- Rates are variable and can spike. In one-sided markets the funding rate can rise sharply, making the cost of holding the crowded side expensive.
- It does not protect you from price risk. Funding keeps the contract near spot; it does nothing to shield you from the leverage and liquidation risks that dominate futures.
Funding rate is a cost to manage, not a source of guaranteed income — and never a reason to hold a losing position.

A Practical Next Step
Before real trading, watch how funding is charged in a demo account. WEEX offers a demo futures mode with virtual funds where you can hold a position across funding intervals and see the effect on your balance. When trading real perpetuals, factor funding into your plan — check the current rate before opening and account for it if you intend to hold.
Download the WEEX app, open the futures section, and observe funding in demo mode first.
FAQ
Q. Who do I pay the funding rate to? A. Other traders — not the exchange. Funding is exchanged between long and short position holders to keep the perpetual price near spot.
Q. How often is funding charged? A. At fixed intervals set by the platform (commonly every few hours). Check the specific schedule and current rate on your platform.
Q. Is a negative funding rate good for me? A. If you are long, a negative rate means you receive funding; if you are short, you pay it. It depends on your position's direction.
Q. Does funding rate affect spot trading? A. No. Funding applies to perpetual futures, not to buying and holding coins on the spot market.
