Funding rates are the most underused signal in crypto. Every 8 hours, perpetual futures exchanges settle a payment between longs and shorts. When the rate is positive, longs pay shorts. When negative, shorts pay longs.
Simple concept, but the implications are significant.
Why Funding Rates Matter
Funding rates reflect real money flowing between positions. Unlike technical indicators derived from price, funding rates show you what traders are actually paying to hold their positions.
- High positive rates (>0.03% per 8h / >40% annualised): Market is crowded long. Longs are paying a premium to hold. Historically, this precedes corrections.
- Deeply negative rates (<-0.01%): Shorts are dominant and paying to stay short. Often seen at local bottoms.
- Near zero: Market is balanced. No strong directional bias from leveraged traders.
Cross-Exchange Spreads Are the Real Signal
A funding rate on one exchange is interesting. The spread between exchanges is where the edge lives.
When Bybit shows +0.05% and another venue shows +0.01% on the same asset, it tells you:
- Leverage concentration differs between venues
- Arbitrageurs haven't fully equalised the imbalance
- There may be a carry trade opportunity (short the expensive venue, long the cheap one)
What the Data Shows Right Now
I built FundingKai to track funding rates across exchanges for 10 major assets. The data refreshes three times daily from live exchange APIs.
Some patterns I've observed from running this data pipeline:
- BTC funding tends to lead altcoin funding by 2-4 hours during momentum shifts
- Cross-exchange spreads widen during volatility — settlement edges become more pronounced
- Weekend funding rates compress as institutional desks reduce exposure
How to Read the Data
If you want to start monitoring funding rates:
- Track the annualised rate, not the raw 8h number. A 0.01% rate looks tiny but compounds to ~13% annually.
- Watch for rate inversions — when a usually-positive asset flips negative (or vice versa), something is changing.
- Compare at least two exchanges to distinguish venue-specific noise from genuine market sentiment.
The raw data for 10 assets across multiple exchanges is available at fundingkai.com/rates. Updated three times daily.
I'm building FundingKai as an open data project for crypto funding rate analysis. No trading advice, no performance claims — just data and the patterns in it.
