Thing is that these interest rates are not really high by historical norms, which is what plenty of us have said for years, to be greeted with "but bust of they go up" as a defence.
Interest rates in effect being very low have seen savers subsidising borrowers. I would say current rates are maybe a smidge too high, but are far better reflecting the risks than when they are at basically zero.
Whilst the short term impact of rates on savers is to get them to lower spending and save over time it will slowly encourage them to spend as well.
I get that people with large mortgages are suffering, but they are not the only borrowers.
Ideally I would like to see UK rates closer to US rates over a longer period. We have historically tracked a bit higher.
