What are the CPI & HICP?
The Consumer Prices (CPI) and the Harmonised Index of Consumer Prices (HICP) are the same index. The index has been designed as a macro-economic measure of consumer price inflation. It forms the basis for the Government's inflation target which the Bank of England's Monetary Policy Committee is required to achieve. It has been developed according to internationally agreed rules and is internationally known as the HICP. The HICP is used for international comparisons of inflation.
