Eurobonds are proposed government bonds to be issued in euros jointly by the European Union's 19 eurozone states. Eurobonds are debt investments whereby an investor lends a certain amount of money, for a certain amount of time, with a certain interest rate, to the eurozone bloc as a group. This money is then forwarded to individual governments for their use. Each government bears the responsibility for repaying the loan when it is due, but collectively the EU is ultimately responsible for the debt. The proposal was floated again in 2020 as a potential response to the impacts of the 2020 coronavirus pandemic in Europe, now commonly known as "corona bonds".
