Some further thoughts on these changes ...
It was poor practice by the NTMA to not give 2 months notice of the rate changes on their instant access and 30 day notice account. This is something that banks are required to do.
Also, the NTMA did not clearly state the comparable old AER for their instant access account and 30 day notice account in notices about the change. This is something that banks are required to do and is good practice.
There is no reason for anyone, who cares about a return on their money, to keep open the NTMA instant access or 30 day notice account.
The NTMA 3.00% for 30 day notice was propping up instant access, notice account and short term deposit market. Hence, rates are now likely to drop on banks deposit products.
The ball is now seems to be in PTSB's court to cut rates. PTSB have the highest regular saver, highest 1 year term deposit, highest children/teen savings rate and some of the highest notice account rates.
