The central bank said the agency needs to be operating before the ECB takes over as banking supervisor with powers to declare that a bank is in trouble. The idea behind the restructuring, or "resolution," agency is that it would prevent the cost of dealing with troubled banks from hurting national finances.
The bank restructuring agency is one part of the EU's proposed "banking union." The idea is to move supervision of banks to the EU level and away from national supervisors and regulators who can be reluctant to point out troubles at their home banks.
Failed banks were a key factor in Europe's crisis over too much debt. For instance, the cost of bailouts bankrupted Ireland in 2010 and forced it to seek rescue loans from the other eurozone governments and the International Monetary Fund. Banks that continue to operate with strained finances often cannot make new loans to businesses at affordable interest rates, one factor contributing to the eurozone's sluggish growth and high unemployment.
The EU rejected German arguments that the new resolution agency requires a change in the EU treaty. The ECB says recent changes in the proposal mean it can be adopted by the EU parliament and member governments.
