I have commented on Target2 liabilities before.
Perhaps a Mish-modified translation from the Welt article Imbalance in the Euro System Reaches a New Record will ring a bell.
The central banks of Germany's euro partners Italy, Spain and France owe the Bundesbank almost a trillion euros . This is a new high. - more than ever before. Tendency continues to rise. There is no security for this money.
Read that last line again and again until it sinks in. Italy is €464.7 billion in the hole. Spain is €376.6 billion in the hole.
Debtors owe Germany, the Netherlands, and Finland over €1.157 trillion.
In May, Italian liabilities increased by almost 40 billion euros.
