The official leading the stress tests of euro zone banks has said the Irish banks still have outstanding work to do to deal with mortgage arrears.

Danièle Nouy, chairperson of the European Central Bank's Single Supervisory Mechanism, said that "a lot has been done" but there was still a lot of work remaining.

"The momentum has to be kept and in particular the mortgage arrears have to be fixed the sooner the better in order for the Irish banking system to be back in a steady state."

Ms Nouy was speaking to RTÉ News following her address to an Irish Banking Federation conference in Dublin.

Her comments were echoed by Peter Breuer, the IMF's representative in Ireland, who was speaking at the Institute of International and European Affairs.

Mr Breuer said: "Overall, non-performing loans in Irish banks are quite high at 27%. So we do think that needs to be dealt with. Now the procedures in are in place Ireland has made good progress over the last or so."

Mr Breuer is finishing his job in Ireland this week and will return to Washington following Ireland's exit from the bailout.

'Sufficient liquidity' for banks to raise capital

Speaking generally about the ECB stress tests, Ms Nouy said there was sufficient liquidity in the market if euro zone banks want to raise more capital as they prepare for pivotal stress tests later this year.

The SSM is preparing to run the rule over 128 banks it will begin supervising from November in stress tests billed as the toughest yet after previous exercises failed to convince markets. 

Banks have taken action on capital ahead of the tests and strengthened their balance sheets by €104bn in the nine months to April through, for example, capital hikes or increased provisions, the ECB said at the time. 

"The markets are in a reasonably benign situation and there is liquidity ready to be invested in banks, in equity or funding, if the markets are convinced by the transparency exercise that we are undertaking," Ms Nouy said when asked if the ECB expected banks to carry out more capital raising. 

The ECB's review, aimed at encouraging banks to recognise losses on loans or investments that have gone bad so that they can regain investor trust and help the euro zone's fragile recovery, was well on track to achieving its goals, Ms Nouy said. 

Speaking at the Dublin conference, Ms Nouy said the SSM had received over 14,000 applications for 800 jobs it plans to fill by the end of the summer

ECB has received over 14,000 applications for 800 jobs

Speaking at the conference attended by chief executives and senior officials from the country's main banks, Ms Nouy said the SSM had received over 14,000 applications for 800 jobs it plans to fill by the end of the summer. 

The ECB had said at the end of May that it had received 8,000 applications for SSM jobs, which have a top salary of €245,000 a year and enjoy the low tax rates of those working for a supranational authority. 

Ms Nouy, formerly a French regulator, said the ECB would publish a guide to the supervisory practices and methodology of the SSM before it takes on the role of supervisor, to ensure transparency. 

She added that national supervisors would play a "major role" in this year's assessment and that the ECB would largely rely on them to provide the risk assessment and Supervisory Review and Evaluation Process (SREP) elements as its own systems need further field-testing. 

One of those regulators, the Central Bank's deputy governor Cyril Roux, said he expected a first submission of an interrogation of loan books as part of the SSM's asset quality review to be made at the end of the month. 

Roux, the head of regulation at the Central Bank, also said that the Bank would review its supervisory model for smaller banks, many of whom are based in the Irish Financial Services Centre.

Ireland's local banks, a rescue of which which cost the state the equivalent of 40% of annual output, will be subject to the ECB's tests. 

Nouy said that while work was still needed, particularly on troubled mortgages, the restructured Irish banking sector was moving in the right direction.

"What had to be done has been done or is being done and the Irish banks at the end of these reforms will be able to finance the economy," she said.
