This paper focuses on the mark-to-model valuation of open foreign exchange (FX) forwards, a popular instrument for hedging FX exposures with higher degree of flexibility with respect to settlement date and settlement amount compared to (standard) closed forwards. While there is sufficient coverage of valuation models and risks of closed FX forwards in literature (see e.g. Hull 2012), we observe limited or no coverage on open forwards in spite of the increasing utilization of those hedging instruments globally. The paper introduces a standard mark-to-model approach for open FX forwards in dependence of the window period of the open FX forward, with the model being tested using swing-option pricing methods based on the Longstaff-Schwartz algorithm (Longstaff and Schwartz, 2001) as well as forward-based pricing approaches (Hull (2012), Jorion (2010)).
To our knowledge, this is the first paper focusing on mark-to-model valuations of open FX forwards within the framework of a stochastic model.
