Euroollars are deposits denominated in United States dollars at banks outside the United States, and thus are not under the jurisdiction of the Federal Reserve. Consequently, such deposits are subject to much less regulation than similar deposits within the United States, allowing for higher margins. There is nothing "European" about Eurodollar deposits; a US dollar-denominated deposit in Tokyo or Caracas would likewise be deemed Eurodollar deposits. Neither is there any connection with the euro currency.
