Perpetual futures have transformed the trading landscape by allowing traders to hold positions indefinitely, unlike traditional futures contracts, which have fixed expiration dates. However, since perpetual futures do not expire, there must be a mechanism to ensure that their prices remain closely aligned with the underlying spot asset. This is where the funding rate plays a crucial role.
A clear understanding of how the funding rate functions is essential for traders navigating the perpetual futures market, as it directly impacts costs, profitability, and overall market stability.
Why do perpetual futures require a funding rate?
One key characteristic of perpetual futures is that their prices can diverge from the spot market price due to varying supply and demand dynamics. Unlike traditional futures, where convergence occurs naturally as the contract approaches expiration, perpetual contracts have no expiry, meaning prices can drift without a built-in mechanism to realign them.
To prevent long-term price distortions, the funding rate incentivizes traders to take positions that help maintain price equilibrium between perpetual futures and the spot market. But what exactly causes these price divergences in the first place?
Several factors influence the price divergence between perpetual futures and spot markets:
- Market Sentiment & Positioning
Market sentiment plays a crucial role in shaping perpetual futures prices. When the majority of traders hold long positions, demand for the contract increases, pushing the perpetual futures price above the spot price. This condition, known as contango, signals bullish market expectations. Conversely, when most traders are shorting the contract, selling pressure drives the perpetual price below the spot price - a state known as backwardation - indicating bearish sentiment. - Speculation & Leverage Effects
Perpetual futures allow traders to take leveraged positions, amplifying market movements. Unlike spot trading, where traders buy assets outright, leveraged trading enables larger positions with less capital, increasing exposure to price fluctuations. In highly bullish conditions, traders using leverage to take long positions can drive the perpetual price further above the spot price. In a bearish market, excessive shorting can push the perpetual price below the spot price. This self-reinforcing cycle can lead to increased volatility, as traders react to price movements by either adding to their positions or liquidating to cover losses. - Liquidity Imbalances & Market Participation
Liquidity is essential for maintaining price stability in any market. If one side of the market dominates, either with too many buyers (demand) or too many sellers (supply), prices can diverge significantly from the underlying spot price. When buying pressure outweighs selling pressure, liquidity providers may struggle to meet demand, causing the perpetual price to rise relative to spot. When selling pressure is excessive, an oversupply of contracts may push the perpetual price below the spot price.
What is the funding rate?
The funding rate is a periodic payment exchanged between traders who hold long and short positions in a perpetual futures contract. The funding rate mechanism encourages market participants to take counterbalancing positions, helping to maintain price stability.
Funding rates are determined by the difference between the perpetual contract price and the underlying spot price:
- Positive Funding Rate: When the market is bullish, and the contract price exceeds the spot price, traders holding long positions pay those holding short positions, and traders are incentivized to short the contract, bringing the contract price back in line.
- Negative Funding Rate: In bearish markets, where the contract price is below the spot price, traders holding short positions pay those holding long positions. The funding rate incentivizes traders to take long positions, driving the contract price up.
How is the funding rate applied?
- Identifying Price Differences
The premium index monitors the spread between the perpetual futures price and the spot price. However, minor deviations do not trigger funding payments unless they surpass a predefined threshold. This ensures that only significant price discrepancies result in adjustments, maintaining market efficiency. - Activating the Funding Rate
When the price difference exceeds the threshold, the funding rate mechanism is triggered. At this point, funding payments flow between long and short traders, depending on whether the market is in contango (positive funding) or backwardation (negative funding). These payments occur at scheduled intervals to encourage traders to take positions that help restore price alignment. - Averaging for Stability
To prevent funding rates from reacting to short-term fluctuations, the calculation is based on an average of price differences over a set period (e.g., 4 hours). This approach smooths out volatility and ensures a more predictable funding mechanism. - Capping for Controlled Adjustments
To maintain stability, the funding rate operates within a controlled range. Capping is a maximum funding rate limit that is applied to prevent extreme values, ensuring funding costs remain predictable and preventing excessive market disruptions.
Implications for Traders
The funding rate can impact a trader’s profitability, especially for positions held over long periods. Considerations regarding the funding rate include:
- Cost of Holding Positions: A high positive or negative funding rate can make it expensive to hold a position for an extended time. Traders should factor in these costs to their strategies.
- Market Sentiment Indicator: The funding rate often reflects market sentiment. A strongly positive rate indicates bullish sentiment, while a negative rate suggests bearishness.
- Arbitrage Opportunities: Differences in funding rates across exchanges can create arbitrage opportunities for savvy traders.

Investing involves risks. The value of investments can go up as well as down and you may receive back less than your original investment or lose your entire investment. Investing with leverage means the value of your investment fluctuates more than the price of the underlying asset.
