Switching to "lower rates" is what landed all the tracker mortgage switching people in trouble in the first place.
Yes agreed (to a degree). There are other aspects to this as well
1. Neither customers or banks realised the true value of the low cost trackers at the time, otherwise customers would never have given them up and banks would never have offered them
2. The ECB has maintained a historic low for a long time, in particular since 2013. Back when the majority of these scandals occurred, the ECB rate was 4%+ so was not as attractive. No one at the time could have forecast the ECB reduce to below 1% for the duration they have
3. The interpretation by the banks of the wording of the mortgage contracts, and the lack of a proper consumer protection group (FSO & Central Bank have been asleep at the wheel here for too long), meant the banks got away with it. The banks have cleared abused there powers here, and our institutions are not strong enough in dealing with them.
4. The other elephant in the room here is the fact that these customers were moved to excessive SVR rates to help return the banks to profitability. If the customers had been charged the european average 1.8% variable rate rather than the 4.5%+ most were moved to, the issue would not have been as material. The fact is there were hit three times - firstly to pay the cost to bail out the banks, secondly the trackers were not offered back and thirdly put on an excessive SVR rate.
But I agree with the sentiment - people fear the banks power, and their current attitude towards the institutions such as the Central Bank and Finance Committee means there is a strong distrust towards them. They believe the banks are not going to do anything to favour the customer without a catch, and therefore suspicious of why they are offering a better rate to them.
Without being able to address this issue, and explain it to the average joe soap, there will be limited movement in this area sadly. The tracker scandal has the downside of making people mistrust banks even more.
