## Calendar Spread Efficiency

Calendar spread efficiency refers to the state where the relationship between options of different expirations is priced correctly, preventing risk-free profits. A calendar spread involves selling an option with a near-term expiration and buying one with a longer-term expiration.

The efficiency of these spreads depends on the market's expectation of how volatility will change over time, known as the term structure. If the market misprices the decay or growth of volatility, arbitrageurs will step in to align the prices.

In crypto, where market cycles can be extremely compressed, maintaining this efficiency is difficult but essential for institutional traders. Efficient pricing ensures that the term structure of volatility is logical and reflects the cost of carry and market expectations for future price action.
