Commentary: The ECB's Dangerous Game

Jean Claude Trichet and his colleagues at the ECB are playing a dangerous game. Despite the euro zone's recovery still looking very fragile, the central bank's key playmakers seem determined to talk about pushing policy back onto a more "normal" footing.

Just last week the Bundesbank's Axel Weber in a speech given in New York indicated his desire to see monetary policy quickly and effectively tightened.

This very open desire to get policy back onto a more normal footing is a mistake for the simple reason that it is going to push the euro higher and make exports less competitive at a time when Europe is producing little domestic demand of its own.

Foreign exchange traders have already moved the euro's exchange rate past $1.40 and there is no reason to think that $1.50 or even $1.60 can be ruled out.

The gamble that the ECB is taking by simply talking about a move to the monetary policy exit sign is a huge but unnecessary one.

While the likes of Weber may be convinced that it's the right thing to do, with such an opaque macroeconomic environment why does he feel the need to talk about it? Why take the risk? It's not as if there is a near-term inflation issue to tackle.

The ECB has tightened inappropriately in the past and could make the same mistake again. The best approach now would be to say nothing. By saying nothing, the central bank would allow itself options.

By saying nothing, the ECB might not see the euro rise at such a dramatic pace. By saying nothing, the ECB wouldn't run the very real risk of damaging its credibly again by performing a policy U-turn.

Don't get me wrong; I am not saying that other central banks around the world are not taking big risks as well. The Fed's headlong rush towards the second round of quantitative easing could well be extremely reckless.

But the fact that the Fed is getting ready to move in the opposite direction to the ECB should give those in Frankfurt pause for thought.

It's not too late for the ECB to sit on the sidelines keeping its own council while the economic fog clears. If it turns out that a tighter monetary environment is required in 12 months, then it hasn't lost anything by saying nothing now.

However, if it turns out that economic growth it still likely to remain sub-par, then those at the ECB would still be able to provide assistance without anybody questioning their competence.

This is especially true for Axel Weber. If the boss of the Bundesbank wants to take over from Jean Claude Trichet next year, then he can't make any mistakes.
