Funding rate in crypto: what it is and how to read it
Updated 2026-05-22
Funding rate is a periodic payment between long and short perpetual holders. Its job is to keep the perpetual price anchored to spot. When the perp trades above spot, longs pay shorts. When it trades below, shorts pay longs. Binance, Bybit and OKX settle every 8 hours; Hyperliquid every hour.
How funding rate works
Perpetual futures have no expiry. Without an enforced convergence to spot, the perp price would drift arbitrarily. Bull markets push perps to a premium, bear markets push them to a discount. Funding is the mechanism that closes that gap. At each settlement, the exchange transfers a small payment directly between long and short holders (not between users and the exchange itself).
The funding rate is calculated from the perp-spot premium and an interest component. A simplified formula: funding ≈ clamp(premium_index + interest_rate, −0.75%, +0.75%). The premium index averages the perp-spot gap over the funding interval; the interest rate is small and flat (~0.01% per 8h on Binance). Each exchange publishes its own formula and clamp range.
Positive funding means longs pay shorts. The signal: bullish positioning is crowded enough that the exchange has to tax it. Negative funding means shorts pay longs. The signal: bearish positioning is crowded.
8-hour CEX cycle versus Hyperliquid hourly
Binance, Bybit and OKX all settle funding three times a day, at 00:00, 08:00 and 16:00 UTC. The published 8-hour rate is what is paid in one cycle. To annualise it, multiply by 3 (cycles per day) × 365 = 1,095. A 0.01% 8h rate is roughly 11% APR carry. A 0.10% rate is ~110% APR.
Hyperliquid uses a 1-hour cycle. The per-cycle rate is roughly one-eighth of a comparable CEX rate, so the eight-cycle sum across a single CEX day is similar. The smaller per-print magnitude means Hyperliquid funding plots tend to look quieter, but the cumulative cost of holding a position is comparable when the basis is the same.
Reading the rate against history
A single funding print does not say much in isolation. The same +0.01% can be neutral on BTC and extreme on a low-liquidity altcoin. The right comparison is the asset's own distribution. The MarketTrace funding scoreboard ranks the current rate against the venue's last two years of history (about 2,200 cycles per CEX, over 17,000 on Hyperliquid). The percentile tells you whether this print is normal, hot, or capitulatory.
A funding streak is the run of consecutive cycles that share the same sign. A 3-day negative streak on BTC is nine consecutive negative cycles. Long streaks in either direction tend to compound positioning until a flush clears it. The scoreboard flags streaks in the top 10% of historical same-direction runs.
How funding shows up in trading
Carry: holding a perp position is not free. A long at +0.10% 8h funding pays ~3% of notional per month even if price does not move. For a 10× leveraged position this is 30% of margin per month. Funding is the hidden cost of patience.
Arbitrage: when funding diverges between venues (Binance at +0.05%, Hyperliquid at +0.01%), a delta-neutral pair (short the high-funding venue, long the low-funding venue) earns the spread minus fees. The MarketTrace funding scoreboard shows the per-venue rate side by side, which surfaces arb candidates directly.
Mean reversion: extreme funding readings (top or bottom 1% of history) historically precede price reversals. The mechanism: a one-sided book that pays steep carry attracts contrarian flow until the imbalance resolves. The scoreboard flags rare prints with their historical percentile.

Frequently asked questions
What does a negative funding rate mean?
Negative funding means short positions pay long positions at each settlement. The perp is trading below spot, so the exchange incentivises longs to take the other side and push the perp back toward spot. Sustained negative funding is usually a sign of bearish positioning or short-side carry trades dominating the order book.
Who pays funding — longs or shorts?
Longs pay shorts when the funding rate is positive. Shorts pay longs when it is negative. The payment is funding rate × notional value, charged at each settlement (every 8 hours on Binance, Bybit and OKX; every hour on Hyperliquid). On a $10,000 BTC long at +0.01% funding, the position pays $1 every 8h, or about $90/month if the rate stays flat.
Why does funding rate exist?
Perpetual futures never expire. Without a forced convergence to spot, they would drift arbitrarily. Funding is the convergence mechanism: when the perp trades above spot, longs are taxed and shorts are subsidised, pulling the perp down. When the perp trades below, the reverse. The funding rate is calculated from the perp-spot premium plus an interest component.
How often does funding settle on each exchange?
Binance USDⓈ-M, Bybit USDT and OKX swaps settle every 8 hours at 00:00, 08:00 and 16:00 UTC. Hyperliquid settles every hour. A position held for 24 hours pays funding three times on the CEXs and 24 times on Hyperliquid. The per-cycle rate on Hyperliquid is roughly one-eighth of the equivalent CEX rate, so cumulative cost over a day is similar when the perp basis is the same.
What is a high funding rate in crypto?
High depends on the asset's own history. A 0.01% 8h rate is normal for BTC; sustained 0.10% (which compounds to ~30% APR) is the historical 99th percentile and almost always preceded a long flush. The MarketTrace funding scoreboard ranks the current rate against the last two years of history per venue so the percentile is honest about regime.
