Yes, I remember these numbers floating around last year during the Oireachtas committee sessions. And this was after PTSB contacted them 3 times to recommend changing from SVR to MVR. I fully accept people do not trust banks, but surely most people have someone they can ask for advice of this nature. If you cannot switch banks, you should definitely want the lowest rate possible from them until you are in a position to switch !The last time I asked which was probably a year ago, only 20% of ptsb customers had availed of the right to switch to the lower new business rate.
You cannot force people to want lower rates - this can only be done through financial education !
