Volatility Swap Payoff

Calculation

A volatility swap payoff represents the difference between realized volatility and implied volatility over a specified period, settled in cash. This derivative instrument allows market participants to trade volatility exposure without directly holding the underlying asset, offering a synthetic long or short volatility position. The payoff is determined by the variance swap’s notional principal multiplied by the difference between the realized variance and the strike variance, effectively transferring volatility risk. Accurate calculation of realized volatility, often using historical price data, is crucial for determining the swap’s value and subsequent payout.
