Live annualized basis between BTC spot and the nearest Binance quarterly futures contract. Track contango and backwardation — key derivatives market health signals. Updated every 15 minutes.
The basis is the spread between a quarterly futures contract price and the spot price. When futures trade above spot, the market is in contango — buyers are willing to pay a premium for deferred settlement. When futures trade below spot, the market is in backwardation — an unusual condition that has historically signalled stress or forced selling.
The annualized basis normalizes the raw spread to a yearly rate so it can be compared across different times to expiry: annualized = raw_basis_pct × (365 / days_to_expiry). A 2% raw basis with 90 days to expiry ≈ 8% annualized.
This tool tracks the nearest Binance quarterly futures contract (not the perpetual). The quarterly basis reflects longer-term market sentiment and carry-trade demand; it differs from the perpetual funding rate, which resets every 8 hours.
