Differences in coverage and weights can widen the gap during sharp rises in energy and food prices. Insee describes IPCH as suitable for cross-country comparisons and IPC as closer to tracking the purchasing power of money. The article is a methodology review rather than a new monthly inflation release; the choice of indicator depends on what is being measured.
