How Funding Rates Link Crypto Perpetual Futures to Spot Prices
Summary
The article contrasts conventional futures, which expire and settle on set dates, with crypto perpetual futures, which have no expiry. Because perpetual contracts do not settle by converging with spot at expiration, the document explains that funding payments serve as a recurring mechanism to encourage alignment between perpetual and spot prices. Payments pass between long and short position holders, with the direction depending on the relationship between contract and spot prices.
Funding can make it more costly to maintain positions when the perpetual market diverges from spot, potentially encouraging traders to adjust positions and helping limit persistent gaps. The article says funding is recalculated periodically and gives one exchange’s stated schedule as an example. It offers a conceptual explanation, not a quantitative study: it does not specify a general funding formula, show historical convergence evidence, or analyze the effect of fees, leverage, and liquidation risk. Funding should therefore be understood as one market mechanism, not a guarantee that prices remain aligned.
Key ideas
- Traditional futures expire, while perpetual futures allow positions to remain open without a scheduled settlement date.
- Funding payments move between long and short holders according to the gap between perpetual and spot prices.
- Funding is intended to discourage persistent divergence between perpetual contracts and spot markets.
- Funding costs can affect the economics of holding a leveraged position.
- The article explains the mechanism conceptually but provides no empirical analysis or complete pricing model.
