Variance Swaps
A variance swap is a financial derivative that allows traders to speculate on or hedge against the realized volatility of an asset. The payoff is based on the difference between the realized variance of the asset price and a pre-agreed strike variance.
Unlike options, which have non-linear payoffs, variance swaps provide a linear exposure to variance. This makes them highly effective for managing volatility risk without the need for constant delta hedging.
In the crypto ecosystem, variance swaps are becoming more common as a way for institutional investors to gain pure exposure to volatility. They allow participants to express a view on whether market fluctuations will be higher or lower than currently expected.
Because they are cash-settled, they provide a clean mechanism for trading volatility as an asset class itself.
