PPI may stand for Producer Price Index, but after checking the data below it could stand for Probably Painfully Incorrect. That is because it is nearly impossible to reconcile the data below with any other data. These numbers do not dovetail with any other known data on material prices. How the outliers of mining and raw materials impact overall PPI, which is in the positive at 4%, remains to be seen. We cannot answer that, but what we can say for sure is that this data does not match and is therefore to be considered with suspicion.
