I've just noticed that my IF ISA [1] has been credited with less interest this month than I expected (less than the previous month in fact, quite impressive given the balance is greater). I'm not aware of the interest rate having changed.
I've emailed IF to ask them to investigate, but any other IF accountholders might want to check their recent interest credits in case this is a widespread problem. (I'm presuming this may be a potentially widespread problem as computers tend to fsck up either not at all, or quite spectacularly..)
[1] Yes, I know it's now a fairly unimpressive ISA, but come April I'm moving. Unfortunately, the ISA I'd like to move to doesn't accept transfers-in (otherwise I'd have moved already), but as my balance is less than even one year's maximum deposit, is there actually anything to stop me entirely legally just doing a physical withdrawal and then depositing "raw cash" in a new ISA come 6 April, since I wouldn't be breaching the maximum annual deposit limit (even taking into account further deposits next tax year)?
