Call to change method to measure RPI inflation
Three of the four proposals made by the Office for National Statistics (ONS) in the public consultation it launched yesterday would lead to a retail price index that is closer to the consumer price index (CPI), which is typically lower. The remaining suggestion is for no change.
Aligning the long-standing RPI more closely to the newer CPI could save Chancellor of the Exchequer George Osborne £3bn a year in debt interest payments, but it risks alienating bondholders as RPI is used to calculate returns on index-linked gilts.
RPI is used to calculate some private sector annual pay settlements and rises for many private pensions among other con- tracts.
