We are fascinated with commodity charts drawn with "real" prices. Without
getting into the debate as to the reliability of "government" statistics on
inflation, we have drawn inflation adjusted charts using CPI (Consumer Price
Index), PPI (Producer Price Index) and PCE (Personal Consumption Expenditures).
For this Observation we are going to highlight charts of nominal and "real" crude
oil prices.
Our "look" begins with a long-term chart of nominal crude oil prices.
• Chart 1 Notes: Nominal crude oil prices have been trading in
a broad range from roughly $10/bbl. to $40/bbl. since 1980. The price appears
to be trying to break out of the upper end of that trading range.
The following three charts show both the nominal price of oil and a "real" price
using the three major inflation gauges (CPI, PPI and PCE - Personal Consumption
Expenditures) for calculating a "real" price.



• Notes for Charts 2, 3 and 4: The "real" price of oil peaks
in 1980 with a secondary peak in 1990. Whereas nominal price bottomed in early
1986 with a secondary bottom in 1998, the "real" price bottomed at the end
of 1998 for each of our charts. We have added a simple downtrend line (in orange)
to each chart to show the decline of "real" prices from 1980. The horizontal
blue line demonstrates the top of the broad trading range of nominal prices.
Summary points:
- The nominal price of oil has recently traded above $40 - the top of a broad
trading range that has existed since 1980.
- The "real" price of oil has broken above a down trend line that connects
the 1980 and 1990 highs.
- Could the break out be for REAL?
