Frequently Asked Questions
Funding rate is a periodic payment between long and short traders to keep perpetual futures price aligned with spot price. Positive funding means longs pay shorts (bullish market), negative means shorts pay longs (bearish market).
Most exchanges charge funding every 8 hours (3 times daily). Some use hourly funding. The rate shown is typically the 8-hour rate. Annual funding rate = 8-hour rate × 3 × 365. A 0.01% 8-hour rate equals ~10.95% annually.
Yes, cash-and-carry arbitrage involves holding spot and shorting perps when funding is positive. You earn funding while being delta-neutral. This strategy works best when funding rates are consistently high (>0.03% per 8h).
High funding indicates imbalanced positions. During bull runs, excessive longs push funding high. During crashes, excessive shorts create negative funding. Extreme funding rates often precede reversals as they become unsustainable.
