What Is a Basis Trade?
A basis trade (also called "cash and carry") is a market-neutral arbitrage strategy that profits from the price difference between an asset's spot market price and its futures contract price. The trader buys spot and simultaneously sells an equivalent futures position, locking in the "basis" as profit.
How the Basis Trade Works
When futures trade in contango (above spot), a trader can:
- Buy 1 BTC on the spot market at $65,000
- Sell 1 BTC futures contract expiring in 3 months at $67,000
- Hold both positions until expiry, earning the $2,000 basis (~3% in 3 months, ~12% annualized)
The trade is market-neutral because long spot and short futures offset each other regardless of price direction.
Why It Matters for Traders
The basis trade is one of the lowest-risk strategies in crypto, offering yields that often exceed traditional fixed income. Institutional players and market makers frequently run this trade, and its prevalence directly affects funding rates and futures curve shape. Understanding basis dynamics helps traders identify when contango is abnormally wide (opportunities) or compressed (risk-off sentiment).
