The first is that the Bank of England takes this fact into account when appraising inflation expectations. If food prices are supposedly now driving inflation, then it is entirely reasonable to expect that inflation will fall significantly and soon precisely because of the decline in bulk food prices. Why is that possibility not being discussed?
Median wage is now some £640 a week. Median household food budget perhaps £60 a week. Food is 10% of incomes therefore (around and about). So, a 10% change in food prices would be perhaps 1% on the general inflation rate.
Difficult to see food as the major driver of the inflation rate really….
Also, somone who knew economics would know that the rate being worried about is the core inflation rate. Which is the one that excludes food and fuel….
