They lose their capacity to issue debt in a currency over which they have full control.(Den egna sedelpressen)
A monetary union is more than just a single currency and a single central bank. Countries that join a monetary union lose more than one instrument of economic policy.
They lose their capacity to issue debt in a currency over which they have full control.
This separation of decisions – debt issuance on the one hand and monetary control on the other – creates a critical vulnerability; a loss of market confidence can unleash a self-fulfilling spiral that drives the country into default (see Kopf 2011).
