Discover the arbitrage opportunities between perpetual contracts and spot margin trading.
Market conditions have been volatile recently, but the overall bullish environment has maintained historically high levels of basis and funding rates, creating significant arbitrage opportunities. With OKX's introduction of the Unified Account feature, capital efficiency for large-scale arbitrage has improved markedly.
Today, we’ll explore a practical arbitrage strategy and how to use OKX’s Unified Account to increase arbitrage returns by 500%.
Arbitrage Strategy: Futures-Spot Arbitrage (Perpetual-Leverage Arbitrage)
The core logic of arbitrage lies in market price discrepancies. In the current crypto derivatives market, the funding rate for perpetual contracts and the fixed interest rate for spot margin trading create a profitable arbitrage window.
Example Scenario
On OKX, the funding rate for ETH/USDT perpetual contracts was recently 0.282%, while ETH’s borrowing rate was 0.05%. For a Level 1 (LV1) user with a 0.05% taker fee, the arbitrage space is:
0.282% (Funding Rate) – 0.05% (Borrowing Rate) – (0.05% × 2 Fees) = 0.132%
Higher-tier users enjoy lower fees, widening the arbitrage potential.
Key Conditions for Arbitrage
- The funding rate received from contracts must exceed the spot margin interest paid.
- Open opposite positions (long in spot margin, short in perpetual contracts) of equal value to lock in profits.
Step-by-Step Execution
When Funding Rate > 0
- Perpetual contract: Short
- Spot margin: Long equivalent value.
When Funding Rate < 0
- Perpetual contract: Long
- Spot margin: Short equivalent value.

Why Capital Efficiency Matters
Traditional split-account models limit leverage due to separate margin pools, reducing returns.
Example: Split-Account Model
- 0.2 ETH split into 0.1 ETH per account.
- Max 3x leverage (to avoid liquidation).
- Daily return: ~1.25% (low efficiency).
Boost Returns by 500% with OKX Unified Account
Unified Accounts share margin, enabling higher leverage without liquidation risks.
Optimized Strategy
- Spot Margin: 10x leverage (0.15 ETH → 1.5 ETH long).
- Perpetual Contract: 75x leverage (0.02 ETH → 1.5 ETH short).
- Daily Return: 7.33% (vs. 1.25% in split accounts).
Liquidation Risk?
- ETH must drop ~74.5% to trigger liquidation.
- Unified Accounts dynamically offset losses between positions.
