You are consultant to an Irish company which is due to make payment for imported components in 90 days time.
All companies are interested in future cash flows.
Buy dollars today and place them in a dollar-denominated deposit which matures on the date of required payment. Let the market ride and buy the dollars at the spot rate of exchange on the day that payment is due. Purchase a call option, allowing you if you wish, to buy the dollars in 90 days time at an agreed exercise price.
