What are the consequences for mortgage holders?
I read somewhere that the banks SVR rates would rise as a consequence of higher borrowing costs for them. So in this instance, it wouldn't matter what the central bank rate dropped to, or how long it stayed at effectively zero, as banks with downgraded credit ratings would just have high mortgage rates full stop.
Whilst my bank isn't in this list that's being mooted, I did spot my lender on the original list of 14 or so banks that Moody's were looking into from a couple of months ago.
