Perpetual futures (perps) have become the dominant derivative product in crypto markets, offering traders exposure to asset prices without expiration dates. Unlike traditional futures, perps don't have a settlement date, making them ideal for both short-term trading and long-term positions.
How Perpetual Futures Work
Perpetual futures mimic the spot market while allowing leverage. The key mechanism that keeps perps trading close to the spot price is the funding rate - a periodic payment between long and short positions.
Key Insight
When funding rates are positive, longs pay shorts. When negative, shorts pay longs. This mechanism helps anchor the perpetual contract price to the spot price.
Funding Rate Mechanics
The funding rate is typically calculated every 8 hours and consists of two components:
- Interest Rate Component: Usually fixed (0.01% per 8 hours)
- Premium Component: Based on the difference between mark price and spot price
Calculating Expected Funding
For a $10,000 long position with 3x leverage during a 0.01% funding rate:
Funding Payment = Position Size × Funding Rate = $30,000 × 0.0001 = $3 every 8 hours
Trading Strategies with Perps
At Larissa Flux, we employ several strategies using perpetual futures:
1. Basis Trading
Capitalizing on the difference between perpetual futures and spot prices. When basis is high, we might short perps and go long spot.
2. Funding Rate Arbitrage
Taking positions based on expected funding rate movements. In high positive funding environments, we might consider short positions to collect funding.
3. Cross-Exchange Arbitrage
Exploiting price differences of the same perpetual contract across different exchanges.
Risk Warning
Perpetual futures involve leverage and funding rate risks. Always use proper risk management, including stop-losses and position sizing appropriate for your risk tolerance.
Market Impact and Liquidity
Perpetual futures have significantly impacted crypto market structure:
- Increased overall market liquidity
- Created new arbitrage opportunities
