Permanent TSB has become the latest mortgage provider to increase its interest rates.
The bank is to raise what it charges for new fixed rate mortgages by an average of 0.51%.
Specifically, the rates on different products will rise by between 0.05% and 0.8%, with the precise change dependent on the loan to value ratio, loan size and term.
The changes will take effect from this coming Monday and will be applied only to those who are taking out a new fixed term rate product.
Those with an existing fixed rate loan will not be impacted, nor will new or existing variable rate mortgage customers.
The bank says that those customers who already have an offer letter and who drawdown their loan by April 14, or by the date on the offer if it is sooner, can avail of the existing rates.
This is Permanent TSB's second mortgage rate increase since the European Central Bank began to hike what it charges for lending money to banks in July last year.
Since then there have been four successive rate rises by the ECB totalling 2.5% which have been aimed at taming inflation.
The last PTSB change to rates came in November when the lender increased them by an average of 0.45%.
In December, the ECB added a further 0.5% to its main lending rate and signalled more is to come.
Irish banks have been slow to pass on the ECB changes to customers, due to their strong deposit bases and increased competition driven by the exits of Ulster Bank and KBC Bank Ireland.
According to data released by the Central Bank of Ireland earlier this week, Irish new mortgage rates are the third lowest in the euro area after Malta and France.
The expectation is, however, that Irish banks will soon be forced to catch up with European counterparts, who have been much quicker in passing on the full effect of the ECB changes to their customers.
