Eurocurrency in the context of "Eurodollar"

Eurodollars are U.S. dollars held in time deposit accounts in banks outside the United States. The term was originally applied to U.S. dollar accounts held in banks situated in Europe, but it expanded over the years to cover U.S. dollar accounts held anywhere outside the U.S. Thus, a U.S. dollar-denominated deposit in Dubai or Singapore would likewise be deemed a Eurodollar deposit (sometimes an Asiadollar). More generally, the euro- prefix can be used to indicate any currency held in a country where it is not the official currency, broadly termed "eurocurrency", for example, Euroyen or even Euroeuro.

Eurodollars have different regulatory requirements than dollars held in U.S. banks. Eurodollars can be riskier than assets held in U.S. banks, which include at least partial deposit insurance, and as a result, demand a higher interest rate.
