Eurocurrency is currency held on deposit outside its home market, i.e., held in banks located outside of the country which issues the currency. For example, a deposit of US dollars held in a bank in London, would be considered eurocurrency, as the US dollar is deposited outside of its home market.

Eurodollars is a financial term used to describe certain U.S. dollar-denominated deposit liabilities (primarily but not exclusively time deposits) held at banks or their branches outside the United States.
