Crypto Funding Rates

What Are Funding Rates?

Funding rates are periodic payments exchanged between long and short traders on perpetual futures contracts. They exist to keep the perpetual contract price aligned with the spot price. Without funding, perpetual contracts would drift away from the underlying asset price.

How Funding Rates Work

Funding is typically charged every 8 hours (00:00, 08:00, 16:00 UTC). If the funding rate is positive, longs pay shorts. If negative, shorts pay longs.

Reading Funding Rates

• Positive rate (green) — Longs pay shorts. Market sentiment is bullish, and more traders are long.
• Negative rate (red) — Shorts pay longs. Market sentiment is bearish, and more traders are short.
• Extremely high rate (>0.05%) — Market is overheated. Potential reversal signal.
• Near zero — Balanced market with no strong directional bias.

Funding Rate Strategies

Funding arbitrage: Hold a long spot position while shorting the perpetual contract (or vice versa). This is delta-neutral — you profit from the funding rate without taking directional risk. Works best when funding rates are consistently high.

Sentiment indicator: Extremely high positive funding rates often precede sell-offs (longs are overcrowded). Extremely negative funding rates can signal a bottom (shorts are overcrowded). Use funding rates alongside other indicators, not in isolation.

Cost of holding: If you're holding a leveraged position for days or weeks, funding costs can add up significantly. A 0.03% rate charged 3x daily is ~33% annualized cost. Always factor this into your trade plan.
