That Courage is not inconsistent with Caution: Foreign Currency Hedging for Superannuation Funds

Abstract

Surveys of Australian superannuation funds verify that most international bond holdings, but not equity holdings, are hedged for currency risk. We compare the mean-variance efficiency of this practice with two alternative strategies: a conventional forward hedge; and a selective hedge triggered by the sign of the interest differential. These strategies produce optimal allocations which stochastically dominate the restricted portfolio according to Barrett-Donald (2003) tests. The advantages of alternative hedging strategies remain when the vector of sample mean returns is replaced by forecasts. Selective hedging works best for equities; conventional hedging for bonds. Adding unhedged bonds does not improve outcomescurrency hedging; portfolio allocation; stochastic dominance
