In the January 23, 2017 issue of Barron’s, in the 2017 Roundtable, Part 2, Jeffrey Gundlach made the comment, “One of the best indicators of the direction of bond yields is the ratio of copper prices to gold prices.” He went on to elaborate, “Copper is an industrial metal. A higher ratio suggest more manufacturing activity, and that implies an uptick in inflation and yields.”
I thought that it would be interesting to see whether there was a correlation between this ratio and CPI, and between this ratio and 10 year US Treasury rates.
