The euro is now a reserve currency only for the core euro-zone countries
Since the euro-zone crisis (2010-2013), the euro is now an international reserve currency only for the core euro-zone countries: Non-European investors invest in bonds of the core countries; those of them (France, to a small degree Belgium and Finland) that have an external deficit are able to finance it without any problem; The peripheral euro-zone countries, on the other hand, have had to eliminate their external deficits, because they could no longer attract foreign capital to finance them; their government bonds are becoming increasingly domestically held : insofar as concerns peripheral-country debt, the euro is no longer a reserve currency. A very significant asymmetry has therefore appeared between the core and the peripheral euro-zone countries: the former enjoy the euro's reserve currency status, but the latter no longer, and obviously this adversely affects them.
