Average Irish mortgage interest rates in June were almost double the average across the euro zone, new figures from the Central Bank show.
The average rate in Ireland of 3.35% is well ahead of the euro area average of 1.83%.
The volume of new mortgage agreements here in June was €562m, bringing the total in the year to June to €5.6 billion.
This compares with total new mortgage lending of €4.5 billon for the previous 12 months to June 2016.
Variable rate mortgages accounted for 60% of all new agreements in Ireland over the past year, however, the proportion of fixed rate mortgages is increasing.
The equivalent euro area share of variable rate mortgages is 15%.
Standard variable mortgage interest rates for outstanding loans fell by 0.12% to 3.34% between Q1 2016 and the same period this year.
1-3 year fixed rates dropped by 0.18% over the same timeframe.
Irish-based banks say interest rates here are considerably higher than other euro area countries because they face higher funding costs than their euro zone counterparts, and that lending to the Irish market is much riskier than it was before the financial crisis.
