ECB are still at historically low rates, but nobody can predict what rates will go. But there is one trend. Irish banks are taking a higher margain to rebalance their books and this seems to be the future trend, and it is not just PTSB. Also I cannot see how AIB and BOI will not at some stage do the same.
The 5 year fixed at 3.7% looks good to me. Certainty and peace of mind and a low interest rate is what you are getting there. Well worth it at that rate.
All those with PTSB who are hopping mad, well just wait until the same happens to AIB and BofI customers. All banks are the same.
