Three mortgage lenders have announced that they are independently raising their mortgage interest rates.
Ulster Bank, First Active and Permanent TSB have increased their standard variable rates by between 0.2 and 0.25 percentage points.
This increase will add an extra €40 a month to a mortgage of 250,000 over a 30-year term.
A spokesman for Permanent TSB, which is the largest mortgage provider in Ireland, said the change reflected the higher cost of money in international markets.
