The price of copper is sometimes referred to as "Everyman's Economist" because
it is highly correlated with the behavior of the manufacturing sector, as illustrated
in Chart 1.
Chart 1
Today on the London Metal Exchange (LME), the price of 3-month forward copper
finished $110 per tonne lower from Tuesday's close. At $6,530 per tonne, this
is the lowest close for 3-month copper since April 20, 2006 (see Chart 2).
Although today's relatively sharp price drop is in part related to the settlement
of a Chilean miners' strike, copper prices have been in a declining trend since
early September. This weakening in copper prices corroborates the slowdown
in the pace of U.S. manufacturing activity - it appears as though manufacturing
output peaked in August 2006 - and the recession in housing. The decline in
the dollar price of copper is all the more indicative of faltering goods-producing
activity in the U.S. inasmuch it has occurred at the same time that the foreign
exchange value of the dollar has been falling. All else the same, the dollar
price of an internationally-traded generic commodity would be expected to rise
as the foreign-exchange value of the dollar fell. The fact that the dollar
price of copper has declined along with the fall in the dollar implies that
the price of copper has declined in terms of other currencies, not just the
dollar. This could suggest that manufacturing activity globally is slowing.

Paul joined the economic research unit of The Northern Trust Company in 1986
as Vice President and Economist, being named Senior Vice President and Director
of Economic Research in 2000. His economic and interest rate forecasts are
used both internally and by clients. The accuracy of the Economic Research
Department's forecasts has consistently been highly-ranked in the Blue Chip
survey of about 50 forecasters over the years. To that point, Paul received
the prestigious 2006 Lawrence R. Klein Award for having the most accurate economic
forecast among the Blue Chip survey participants for the years 2002 through
2005. The accuracy of Paul's 2008 economic forecast was ranked in the top five
of The Wall Street Journal survey panel of economists. In January 2009, The
Wall Street Journal and Forbes cited Paul as one of the few who identified
early on the formation of the housing bubble and foresaw the economic and financial
market havoc that would ensue after the bubble inevitably burst. Through written
commentaries containing his straightforward and often nonconsensus analysis
of economic and financial market issues, Paul has developed a loyal following
in the financial community. The Northern's economic website was listed as one
of the top ten most interesting by The Wall Street Journal. Paul is the co-author
of a book entitled Seven Indicators That Move Markets.
Paul began his career as a research economist at the Federal Reserve Bank
of Chicago. He has taught courses in finance at the DePaul University Kellstadt
Graduate School of Business and at the Northwestern University Kellogg Graduate
