Abstract

In this document we consider the problem of deriving volatilities of non-standard tenors given quotes for standard tenors. Especially, we aim to derive volatilities for caps and swaptions from given quotes for a short tenor, for instance 3m, and derive volatilties for a longer tenor, for instance 6m. Furthermore, we also consider the other way of transforming long tenor volatilities to short tenor ones. We fi rst consider the single curve framework and then transferring the results to a multi curve framework which is the standard market approach after 2007. We apply a displaced di ffusion approach for the volatility transformation. Finally, we give several examples and outline the transfer algorithm.
