FRANKFURT (Reuters) - The European Central Bank expects the euro zone's economic recovery to be moderate and uneven, President Jean-Claude Trichet said yesterday after the bloc's interest rates were held at a record low one percent.

Trichet welcomed a decision to publish the results of stress tests on European banks and said action should be taken where problems came to light.

"Appropriate action will have to be taken where needed," Trichet told a news conference.

European supervisors shored up some confidence in the stress tests they are imposing on banks, as markets focused on finding out more detail about the process before delivering a final verdict.

Europe has listed 91 banks taking part in the tests — including many regional banks where markets suspect most of the problems lie — as it seeks to restore confidence in the sector. The results are due to be published on July 23.
