Permanent TSB is set to increase the rates it pays to depositors from 9 August.
This will be the fourth time the bank has increased rates on its savings and deposit products since last November.
The rates on all fixed term deposit products ranging from 12 months to five years will increase by 0.5%.
Meanwhile, the 12-month and 18-month fixed rates will increase by 0.5% to 1.75% and 2% respectively, and the three-year and five-year rates will increase by 0.5% to 2%.
In addition, the rate on the six-month fixed term deposit will increase by 0.25% to 1%.
Banks are coming under growing pressure to funnel through the benefits of European Central Bank interest rate increases over recent months to those with savings.
Last month, both Bank of Ireland and AIB announced that they were increasing their deposit rates.
