Hi Felicity
Most probably the B of E rate setters are looking and waiting to see how the QE package is going to fare up but I imagine that they have already got some fingers on the "Rise Button". If rates here stay this low too long and other major economies rase their rates before the UK then that could see more money heading over to countries with the higher rates.
The low rates at present are helping a minority with the good, early trackers but I would say that the vast majority are losing out (ie Savers).
I will put my gambling hat on and say 3.5% to 4.0% Bank of England Base Rate by end of 2011, with SVR mortgage rates of around 6.5%. Too early to say for what happens after that but I hope we do not get back to the 10% to 15% base rates but they have happened during previous recessions/crashes and when unemployment reaches high levels like the early 80's.
