AbstractThis paper evaluates an instance of large-scale hedging misfortune in the Australian sugar industry. A single corporation, known as Queensland Sugar Limited (QSL), was responsible for selling the entire volume of sugar exported from Australia. In 2010, QSL incurred over $100 million (2010 AUD) in hedging losses when harvest volumes were below expectations due to heavy La Niña rainfall. Sugar prices rose, and QSL was over-hedged. We quantify the price and production risks faced by Queensland sugar millers, using data that was available at the time. Based on these estimates, we calibrate a mean-variance hedging model to determine QSL's optimal pre-harvest commitment of sugar. We find that QSL should have pre-committed no more than 51% of its expected supply prior to harvest. Under this strategy, QSL would have incurred zero hedging losses in 2010. Speculation by QSL came at the great peril of the Australian sugar growers. © 2020 Elsevier B.V.
