When the European Monetary Union became effective in January 1999, the accounting treatment for claims and obligations which the Eurosystem’s National Central Banks (NCBs) incur against each other in the ‘Trans-European Automated Real-Time Gross Express Transfer’ (TARGET) system remained unspecified. Only later in 1999, the Governing Council of the European Central Bank (ECB) decided that these claims and obligations should be shifted to the ECB’s balance sheet as a central counterparty—a process called ‘novation’. This ex-post decision completed monetary unification by uniquely ‘stitching together’ NCBs’ balance sheets while profoundly transforming the role of the ECB’s balance sheet. First, novation centralised it at the Eurosystem’s apex, which had not been politically feasible ex ante. Secondly, novation repurposed it into a multilateral mechanism to provide automatic, unlimited funding for cross-border payment imbalances. Thirdly, novation allowed monetary technocrats to operationalise it as an autonomous ‘firefighting’ balance sheet for unconventional monetary policy.
