One in ten holders of restructured mortgages are still failing to make any repayment on their loans, according to figures from the Central bank.

The figures indicate that substantial progress is otherwise being made with the stock of permanently modified loans now growing faster than the stock of loans in default.

The stock of permanently modified defaulted loans making full repayments on their modified mortgage amount increased to 55% by the end of 2013.

The figure stood at 28% in 2011.

The Central Bank says the outcome could be down to better loan modification strategies or the improving economic backdrop.

While welcoming the positive trend, it cautions that further work is needed to address the large number of loans which have not been modified.

Over 25,000 fell into that category at the end of 2013.
