A eurobond is an international bond that is denominated in a currency not native to the country where it is issued. They are also called external bonds. They are usually categorised according to the currency in which they are issued: eurodollar, euroyen, and so on. The name became somewhat misleading with the advent of the euro currency in 1999; eurobonds were created in the 1960s, before the euro existed, and thus the etymology is to "European bonds" rather than "bonds denominated in the Euro currency".
