- Notes
- SDDS 'Wholesale Price Index - More Data.xls'. Laspeyres formula, base year 1974=100, weights from 1974 domestic-production value shares (CBSL's SDDS metadata PDF alongside this file); not seasonally adjusted. Discontinued after 2017-09 - the metadata says DCS intended to rebase it to 2008 and, as far as this mirror shows, never published a successor.

Lower confidence than the PPI_M 2022/23 crisis entries, since no specific documented event was matched; left as true_reading rather than open because the value shows no reversion (it holds at the new level rather than snapping back).
