Central bankers normally operate on a longer-term time scale than politicians and therefore do not face the same temptation to relax policy to achieve short-term objectives.

Historically, there has been a positive correlation between wholesale and consumer price inflation, and given this correlation, consumer price inflation too can be expected to soften in the months ahead.
