As the Euro crisis worsens, Paul De Grauwe in Vox:
When it [the ECB] announced its programme of government bond buying it made it known to the financial markets (the enemy) that it thoroughly dislikes it and that it will discontinue it as soon as possible. Some members of the Governing Council of the ECB resigned in disgust at the prospect of having to buy bad bonds. Like the army, the ECB has overwhelming (in fact unlimited) firepower but it made it clear that it is not prepared to use the full strength of its money-creating capacity. What is the likely outcome of such a programme? You guessed it. Defeat by the financial markets.
Financial markets knew that the ECB was not fully committed and that it would stop the programme. As a result, they knew that the stabilisation of the price of government bonds would only be temporary and that after the programme is discontinued prices would probably go down again. Few investors wanted to keep these bonds in their portfolios. As a result, government bonds continued to be sold, and the ECB was forced to buy a lot of them.
There is no sillier way to implement a bond purchase programme than the ECB way. By making it clear from the beginning that it does not trust its own programme, the ECB guaranteed its failure. By signalling that it distrusted the bonds it was buying, it also signalled to investors that they should distrust these too.
Surely once the ECB decided to buy government bonds, there was a better way to run the programme. The ECB should have announced that it was fully committed to using all its firepower to buy government bonds and that it would not allow the bond prices to drop below a given level. In doing so, it would create confidence. Investors know that the ECB has superior firepower, and when they get convinced that the ECB will not hesitate to use it, they will be holding on to their bonds. The beauty of this result is that the ECB won’t have to buy many bonds.
Why has the ECB not been willing to use this obvious and cheaper strategy?
