An offshore bond in the international capital markets, issued in (offshore) Eurocurrency, most frequently in USD.
Eurobonds are, generally speaking, beyond domestic market regulation. Maturities at issue are normally greater than one year and are usually, but not always, in bearer form.
They can be issued on any interest basis. Some attempts are being made to refer to Eurobonds as International bonds.
One reason for this change in terminology is to avoid confusion with the euro (the currency of the euro area, informally Eurozone or Euro zone, introduced some decades after the development of the Eurobond market).
An alternative - and increasingly common - spelling of euro bond, a (currently theoretical) bond backed by all the EU Member States in the euro area.
