The European Central Bank (ECB) and European Banking Authority (EBA) are aiming to carry out a joint stress test on Europe's major banks in September, sources told Reuters.
Austria's FMA markets watchdog said on Wednesday that the EBA plans stress tests this year even as the European Central Bank prepares to take on supervision of top lenders from 2014.
Sources told Reuters that the ECB, which was involved in the background of the last round of EBA stress tests, was set to take a more central role before it assumes supervisory powers over the euro zone's banks.
"The preference is to have the EBA and ECB run together, rather than have the reputational damage of having two (different) ones," said a central bank source.
The tests are "likely to be in September", he added. Other sources said they also expected the tests in September, though the date has not yet been finalized.
"As we said last year, we expect a new round of stress tests in 2013 and discussions are on-going," an EBA spokeswoman said.
ECB Governing Council member Ewald Nowotny said last month that Europe wanted the ECB and the EBA to conduct coordinated stress tests.
EBA Chairman Andrea Enria has said that a key addition to the next test willbe an examination of the quality of assets held by banks to ensure they canabsorb losses properly in a crisis and leave taxpayers off the hook.
The discussions between the ECB and EBA partly focus on working out how tomeasure the quality of banks' loans.
"There will be a stress test this year from the EBA. That is the current status of the decision," Financial Markets Authority co-head Helmut Ettl told a news conference on Wednesday, adding details were still under discussion.
He said Austrian lenders Raiffeisen Zentralbank - the unlisted parent of Raiffeisen Bank International -and Erste Group Bank would be tested.
Europe agreed a deal last month to give the ECB new powers to supervise euro zone banks from 2014, embarking on the first step in a new phase of closer integration to help underpin the euro.
The EBA monitors banks in all 27 EU member states.
