The Premium-EUR System National Adjustment Currencies, the European Currency Snake, and an Orderly Transition

Under the scenario, highly indebted member states may receive interest-free and repayment-free treatment of their sovereign bonds held by the Eurosystem. This relief is strictly conditional on the introduction of a national digital currency and the exclusive issuance of new public debt in that currency. Existing private euro-denominated bonds remain untouched. A preparatory phase (2027–2029) involving the activation of the ECB’s Transmission Protection Instrument and the gradual introduction of the digital euro is outlined to allow an orderly portfolio shift by private investors and to avoid a crisis-driven transition. National currencies would operate within a flexible European exchange-rate mechanism (a modern “snake”), with the euro serving as the hard reference. The exchange rate functions primarily as an adjustment valve rather than a punitive device. Interest and repayment obligations on Eurosystem holdings are reactivated automatically only in the event of renewed euro-denominated borrowing or sustained breaches of predefined rules. The paper examines the incentive effects for governments, national central banks, investors, banks and households, discusses residual risks (including bank balance-sheet mismatches and capital flight), and sketches a technical implementation path based on the multi- and cross-currency capabilities of the TARGET/TIPS infrastructure. The scenario is presented as a thought experiment exploring a hybrid monetary architecture that combines a hard common currency with national adjustment currencies and rule-based discipline.
