Otmar Issing, one of the fathers of the euro, correctly states the principle on which the single currency was founded. As he wrote in the FT last week, the euro was meant to be a monetary union but not a political one. Participating states established a common central bank but refused to surrender the right to tax their citizens to a common authority. This principle was enshrined in the Maastricht treaty and has since been rigorously interpreted by the German constitutional court. The euro was a unique and unusual construction whose viability is now being tested.
The construction is patently flawed. A fully fledged currency requires both a central bank and a Treasury. The Treasury need not be used to tax citizens on an everyday basis but it needs to be available in times of crisis. When the financial system is in danger of collapsing, the central bank can provide liquidity, but only a Treasury can deal with problems of solvency. This is a well-known fact that should have been clear to everyone involved in the creation of the euro. Mr Issing admits that he was among those who believed that “starting monetary union without having established a political union was putting the cart before the horse”.
The European Union was brought into existence by putting the cart before the horse: setting limited but politically attainable targets and timetables, knowing full well that they would not be sufficient and require further steps in due course. But for various reasons the process gradually ground to a halt. The EU is now largely frozen in its present shape.
