Today I telephoned the good folks at the Bureau of Labor Statistics in Washington, D.C. I phoned to find out a little bit more about how one of the key inputs � CRUDE OIL - in PPI [Producer Price Index] is determined each and every month.
Here's the nuts of what I was told:
�Crude oil price data inputs for the PPI are measured from sources of the subject month on the Tuesday of the week that contains the 13th day.�
Sounds good to me.
Now, let's take a look at a chart of one proxy for crude oil � WTI � West Texas Intermediate:

Interesting to note that in a rising market, the sample dates tend to be the �lows for the month� � consistently - even in instances when prices were higher just prior to the sample date.
Many of our financial markets clearly exhibit the finger prints of the same �Orwellian� invisible hand.
