Security Basis

Basis

The security basis, within cryptocurrency derivatives, represents the cost of carry associated with maintaining a hedge between a cash instrument and its corresponding futures contract, reflecting funding rates, storage costs, and convenience yields—or their absence in purely digital assets. Its quantification is crucial for arbitrage strategies, informing relative value trades where discrepancies between spot and futures prices present opportunities for risk-free profit, though imperfect replication introduces basis risk. A negative basis indicates a contango market, where futures prices exceed spot prices, while a positive basis signifies backwardation, often driven by immediate demand exceeding available supply.
