1 A US firm has sold $100 million in exports to another firm in the UK. The current spot rate is $2.00 = 1 so the UK firm has contractually agreed to pay the US firm 50 million in 30 days.

What is the value of the s paid by the UK firm if the $ appreciates by 2%? E. Explain why momentum seems to work when forecasting exchange rates.
