Suppose the spot ask exchange rate, S^a($|), is $1.90 = 1.00 and the spot bid exchange rate, S^b($|), is $1.88 = 1.00. Assume you have $20,000,000 and you buy British pounds. Five minutes later you decide to sell them. If the bid-ask quotes have not changed, how much of your investment as "eaten" by the bid-ask spread?
