Now consider Article 1. "Under the terms of this Decision, Eurosystem central banks may purchase the following: (a) on the secondary market, eligible marketable debt instruments issued by the central governments or public entities of the Member States whose currency is the euro; and (b) on the primary and secondary markets, eligible marketable debt instruments issued by private entities incorporated in the euro area." Now you see the restriction. They can only operate on the secondary market for government debt. But how binding is this restriction? Surely a local central bank can pressure one of its commercial banks (which might already be supported or partially owned by the government) to purchase sovereign debt. That debt could be flipped to the ECB through the SMP.
