Static versus Dynamic Arbitrage Bounds on Multivariate Option Prices

We compare static arbitrage price bounds on basket calls, i.e. bounds that only involve buy-and-hold trading strategies, with the price range obtained within a multivariate generalization of the [BS73] model. While there is no gap between these two sets of prices in the univariate case, we observe here that contrary to our intuition about model risk for at-the-money calls, there is a somewhat large gap between model prices and static arbitrage prices, hence a similarly large set of prices on which a multivariate [BS73] model cannot be calibrated but where no conclusion can be drawn on the presence or not of a static arbitrage opportunity.
