Basis (Futures Basis) Explained

Definition

Basis in crypto refers to the difference between the spot price and the futures price of the same asset.

• Positive basis (contango): Futures price > Spot price
• Negative basis (backwardation): Futures price < Spot price

Why It Matters

• Market Sentiment Indicator: Positive basis often signals bullish sentiment; negative basis suggests bearish expectations.
• Arbitrage Opportunities: Enables cash-and-carry strategies by exploiting price gaps.
• Funding Rate Influence: In perpetual futures, basis relates closely to funding rates.
• Risk Management: Helps assess hedging costs or futures premium/discount.

How It Works

1. Identify spot price.
2. Identify futures price (same asset, specific expiry).
3. Calculate basis: Futures − Spot.
4. Interpret (contango or backwardation).
5. Annualize for longer-term analysis.

Example

ETH Spot: $3,000

3-Month Futures: $3,060

Basis = $60

Traders could borrow ETH at low interest, sell spot, buy futures, and capture convergence profit if costs are below $60.

Common Mistakes
