Fuel price moves are a very important factor in inflation. The economy has had a boost as we heard yesterday with the GDP figures. In part, inflation has fallen from a peak last year at 5.2% down to 2.2% in september.
A large chunk of that fall was because of cheaper fuel bills, and as those fuel bills get more expensive again we could see inflation rise to 2.5% or more and that could hurt the recovery.
