In twelve months, volatility will be 16%. This is the volatility realized. There is a difference of 4%, or 40,000 $US ($1 million x 4%). The seller of the volatility swap pays $40,000 to the swap buyer, provided that the seller holds the leg firm and the buyer holds the floating leg. An agreement between a seller and a buyer to exchange a Straddle option on a given expiration date. On the trading day, counterparties determine both the expiration date and volatility. On the expiry date, the exercise price is set on the Straddle`s at the cash futures value on that date. In other words, the forward volatility agreement is a futures contract on the realized volatility (implied volatility) of a given underlying, whether it is a stock, a stock market index, a currency, an interest rate or a commodity index. etc.
From what I understand, an FVA is a swap on the future implied volatility of at-the-money, which is guaranteed by a front/straddle start option. Volatility swaps are not traditional swaps, with a cash flow exchange between counterparties. In terms of sensitivity, this is similar to that of forward/var start swaps, as you currently have no gamma and are exposed to forward flight. However, it is different from the fact that you are exposed to Standard Vega distortions of vanilla options and MTMs due to distortions, given that the spot moves away from the initial trading date. Volatility swewings are simple volatility instruments that allow investors to speculate exclusively on the volatility movement of an underlying without the influence of its price. Just as investors speculate on asset prices, this instrument allows investors to speculate on the volatility of the asset. Volatility trading allows investors to hedge the volatility risk associated with a derivative position against adverse movements of the underlying/underlying. . .
