Web2.4 Relation between IVP and raw SVI Jim Gatheral developed the SVI model at Merrill Lynch in 1999 and implemented in 2005. The SVI was subsequently decommissioned in 2010 because of its limitations in accurately pricing out of the money variance swaps (for example short maturity Var Swaps on the Eurostoxx are overpriced when using the SVI). WebIn this article, we show how to calibrate the widely-used SVI parameterization of the implied volatility smile in such a way as to guarantee the absence of static arbitrage.
