Funding Rates
What is a Funding Rate
A Funding Rate is a periodic payment between holders of long and short positions in perpetual futures markets.
The mechanism keeps the futures price close to the spot price of the underlying asset.
Formula
Payment = Position Size × Funding Rate
- If the rate is positive → longs pay shorts
- If the rate is negative → shorts pay longs
Payment Intervals
| Exchange | Interval |
|---|---|

APR (Annual Percentage Rate)
CexDex displays rates in APR format — annualized return.
APR = Funding Rate per period × Number of periods per year × 100%
Example for Hyperliquid (hourly funding):
APR = Hourly Rate × 8760 × 100%
Spread
The spread is the difference in APR between two exchanges for the same instrument.
The spread determines the profitability of the arbitrage strategy.
