Swap rate variance swaps

We study the hedging and valuation of generalized variance swaps defined on a forward swap interest rate. Our motivation is the fundamental role of variance swaps in the transfer of variance risk, and the extensive empirical evidence documenting that the variance realized by interest rates is stocha...

We identify a hedging rule involving a static European contract and the gains of a dynamic position on forward interest rate swaps.

The combination of these two features leads to additional terms in the cumulative dynamic trading gains, which depend on realized variance and are taken into consideration in the determination of the appropriate static hedge. We characterize the static payoff function as the solution of an ordinary differential equation, and derive explicitly the associated dynamic strategy.
