His farm has recently exported 10 tonnes of Manuka honey to several retailers in Mexico and is expecting to receive MXN 21,000,000 in exactly 6 months (i.e., 180 days). Heinz is concerned about potential significant changes in the exchange rate between MXN and NZD. Knowing that you received the "Trader of the Month" award, he has called you to seek advice on what to do. At what future spot exchange rate do you think Heinz will be indifferent between the option and money market hedge?
