But are they?But those on non-tracker mortgages are vulnerable
Taking this UB sale specifically for a moment. Are the mortgage contracts not tied to a UB variable interest rate? Irrespective of the fact they've sold to a 3rd party, are they not still tied to the UB rate as long as it's available? I haven't looked at UB contracts, so I might be wrong on this.
It's different in the case of a entity selling their residual book and winding up, as the reference rate ceases to exist.
I try not to generalise, but in the vast majority of non performaning loan sales, it doesn't matter from the purchasers point of view if they charge 0% or 10%. All they will ever hope to get back is the value of the collateral, less legal costs.
