Decentralized Perpetual Futures Funding Rate
A recurring fee paid between traders (longs and shorts) to keep the price of a perpetual futures contract tethered to the actual spot price of the underlying asset.
Funding rates are zero-sum between traders; the protocol itself does not collect the funding fee. The mechanism is purely an algorithmic incentive structure. During massive bull markets, the funding rate can stay highly positive for months, forcing Longs to bleed capital to Shorts.

Imagine two teams pulling a rope. The 'Long' team thinks the price of [Bitcoin](/en/terms/bitcoin) will go up, and the 'Short' team thinks it will go down. If the Long team pulls too hard, the price of the 'fake' Bitcoin contract gets much higher than 'real' Bitcoin. To fix this, the referee (the [smart contract](/en/terms/smart-contract)) makes the Long team pay the Short team a small penalty every hour. This encourages some Longs to quit and some new Shorts to join, pulling the rope back to the middle (the real price).
🤓 Expert Deep Dive
Funding Rate Formula
The funding rate generally consists of two parts: the Interest Rate Component (the difference in borrowing costs between the base and quote currencies) and the Premium Component (the deviation between the perpetual price and the Oracle spot price).
Epochs vs. Continuous Funding
Centralized exchanges like Binance historically settle funding rates every 8 hours. This creates an arbitrage opportunity where traders open positions at hour 7:59 just to collect the fee, causing massive price volatility exactly at funding time. DeFi protocols (like dYdX v4 or Synthetix) avoid this by utilizing Continuous Funding. The premium is calculated and accrued block-by-block (or second-by-second), completely eliminating the 8-hour arbitrage window and resulting in a smoother price curve.
Impact on Liquidation
Traders must maintain a maintenance margin. Because funding fees are automatically deducted from a user's collateral, holding a losing position against a high funding rate will rapidly accelerate the path to liquidation.
❓ Frequently Asked Questions
Who pays the funding fee?
It depends on the market. If the perpetual price is higher than the spot price, Longs pay Shorts. If the perpetual price is lower than the spot price, Shorts pay Longs.
Does the exchange collect the funding fee?
No. The funding rate is purely peer-to-peer. The exchange or smart contract just facilitates the transfer from one side of the market to the other.
What happens if I don't have enough money to pay the funding fee?
The fee is deducted from your deposited collateral. If your collateral drops below the maintenance margin requirement, your position will be liquidated.
