The European market where US dollars can be deposited and loaned for short periods of time. In this market, loans are made in the form of Eurodollars and products are denominated in the US currency. However, because transactions are typically $1 million or more, only large institutional investors participate in this market. Also, because this market is largely unregulated, banks can lend out 100 percent of the deposits they receive and therefore offer extremely attractive interest rates.
