Yesterday the inflation numbers for August were out. CPI was 3.1%, same as the month before, and RPI was 4.7%, down from 4.8%. The unexpectedly high rate was boosted by strong rises in air fares, clothing and food while petrol was down a little, a litre typically costs £1.16 rather than £1.18.
Economists were expecting a sharper fall so sterling had a little boost due to the prospect of the base rate being increased to offset the inflation. That prospect has gone from "distant" to "still a long way off."
