Banks and Exchange Services in Cayman Islands

You should not need to change money in Grand Cayman, since U.S. dollars are readily accepted, though you may get some change in Cayman dollars, which are worth 25% more than a U.S. dollar. ATMs accepting MasterCard and Visa with Cirrus affiliation are readily available in George Town; you usually have the option of U.S. or Cayman dollars. The Cayman dollar is pegged to the U.S. dollar at the rate of CI$1.25 to $1, and divided into a hundred cents, with coins of 1¢, 5¢, 10¢, and 25¢ and notes of $1, $5, $10, $25, $50, and $100. There's no $20 bill. Traveler's checks and major credit cards are widely accepted. Be sure you know which currency is being quoted when making a purchase.
