It may not have stopped the crisis arising, but one thing is pretty clear now, and was clear to me at the time, interest rates should never have gone as high as they did in late 2008
Chasing short term inflation as your one and only gaol for setting interest rates is not smart enough.
Last year inflation was rising due to ridiculous speculation on the price of oil (and pretty much no other reason). This was bound to burn itself out (pardon the pun). So its hard to see how making money itself more expensive was going to bring down inflation. Base rates had little, is any, baring on the oil price speculation.
However, at the same time the first seeds of the current crisis were clearly visible, yet the BoE was still raising interest rates - all that seems to have achieve is giving them more room (but not enough) to cut rates since.
