Bob, wouldn't that be .7 of a percent? Not 7%??? I've seen larger spreads than that when I've been on the island.
No, it is actually about 6.5%, but 7% sounded more dramatic.
Suppose you want to get 1000 pesos. At a rate of 10.8 pesos per dollar, it would cost you 1000 / 10.8 = $92.59 (without fees). At 11.5 pesos/dollar, it would cost you $86.96. The difference is $5.63.
$5.63 / $86.96 = 0.0647, so an exchange rate of 10.8 costs you about 6.5% more than a rate of 11.5 pesos/dollar.
