What Is Calendar Spread?
A calendar spread (or time spread) involves simultaneously buying and selling the same underlying asset with different expiration dates. In crypto futures: buy the near-month contract and sell the far-month contract (or vice versa). In options: buy a longer-dated option and sell a shorter-dated one at the same strike. The trade profits from changes in the term structure rather than directional moves.
How Calendar Spread Works
In crypto futures, calendar spreads profit from changes in the basis between different expiry dates. If you expect the premium to widen (bullish sentiment increasing), buy the front month and sell the back month. If you expect it to narrow, do the opposite. The directional risk is mostly hedged since both legs move with the underlying — only the spread between them matters.
Why It Matters for Traders
Calendar spreads are popular among sophisticated crypto traders because they offer defined risk, lower margin requirements than outright positions, and profit from changes in market structure rather than direction. During periods when the term structure is volatile (switching between contango and backwardation), calendar spreads can generate significant returns with relatively low risk.
