WebOct 1, 2024 · The SVI model is the most popular model that is used by market participants (Gatheral, 2004, Marco and Martini, 2009, Deryabin, 2011, Zhao and Hodges, 2013, Guo et al., 2016. Gatheral and Jacquier Gatheral and Jacquier (2011) prove that the Heston model ( Heston, 1993) converges to the SVI model as the option maturity approaches infinity. 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).
