I would agree with all of that re KBC. I have also tried to no avail to get the new rate on my mortgage.
I am definitely not adverse to switching again in the near future, it is currently not financially practical for me to do so at 3.35% rates.
However, if Frank Money is targeting conservative lending at competitive rates I will definitely evaluate the proposal when it comes out, if they are given approval to operate!
I do believe KBC will have to do something in the event Frank Money takes off. A lot of the switching business in the last 12 months will potentially switch out again if Frank are in the region of 0.75% cheaper (maybe less) than KBC. It will be interesting to see what they do in that case, especially if their less risky asset book is being hit.
However, I would have no faith in KBC to pass on interest rate cuts to existing customers unless it was explicitly written into my mortgage agreement
