Understanding Funding Rate
The funding rate is a mechanism unique to perpetual futures that ensures the contract price stays close to the underlying asset's spot price. Unlike traditional futures that converge to spot at expiration, perpetuals never expire—so they need an alternative mechanism.
When the perpetual price trades above the spot price (indicating bullish sentiment), the funding rate is positive, and long positions pay short positions. When perpetuals trade below spot (bearish sentiment), shorts pay longs. These payments typically occur every 8 hours, though some protocols use different intervals.
Funding rates are expressed as a percentage of position size. A 0.01% funding rate means a trader with a $10,000 position would pay or receive $1 during that funding period.
For RWA perpetuals, funding rates help maintain price fidelity with traditional markets despite operating 24/7 on-chain. Traders often monitor funding rates to gauge market sentiment and identify potential arbitrage opportunities.
