Understanding Funding Rates: The Engine of Arbitrage

Master the mechanics of funding rates, APR calculations, and exchange requirements. Your complete guide to setting up profitable arbitrage strategies.

Funding Rate Fundamentals

What Are Funding Rates?

Funding rates are periodic payments between long and short position holders in perpetual futures markets to keep the futures price tethered to the underlying asset's spot price.

  • Payments occur every 8 hours on most exchanges
  • Positive rates: Longs pay shorts
  • Negative rates: Shorts pay longs
  • Rates vary by exchange and market conditions

Why Do They Exist?

Funding rates prevent perpetual futures prices from diverging significantly from spot prices by incentivizing traders to take positions that bring prices back into alignment.

  • Maintains price stability
  • Reflects market sentiment
  • Balances long and short positions
  • Compensates for price risk

How Rates Are Calculated

Each exchange uses its own methodology, but generally considers the difference between perpetual futures price and the underlying spot price, along with market depth and volatility.

  • Based on price divergence (basis)
  • Market sentiment factor
  • Exchange-specific formulas
  • Updated in real-time

Types of Funding Rates

Positive Funding Rate

When perpetual futures trade at a premium to spot price

Who Pays: Long positions pay short positions

Strategy: Buy spot, Short futures

Example: 0.1% rate: Longs pay 0.1% to shorts every 8 hours

Negative Funding Rate

When perpetual futures trade at a discount to spot price

Who Pays: Short positions pay long positions

Strategy: Short spot, Long futures

Example: -0.1% rate: Shorts pay 0.1% to longs every 8 hours

Understanding APR Calculations

APR Formula

APR = Funding Rate × 3 payments/day × 365 days

Annual Percentage Rate helps normalize funding rates for comparison
