How to read: a +10% annualized basis means an arbitrageur could earn ~10% APR by buying spot and shorting CME futures (cash-and-carry). When this rate is high, retail on Binance/Bybit perps is also paying high funding — sentiment is frothy. Backwardation (negative basis) is rare and usually marks the aftermath of a liquidation cascade. Days-to-expiry is approximated to the next CME monthly roll (last Friday).
