Commodity correlation driven by index funds

30 Nov 2010 by Jim Fickett.

Today Ke Tang and Wei Xiong published an interesting article on VoxEU entitled The financialisation of commodities. The key result is that the prices of those commodities covered by the two most popular commodity index funds show higher correlation than the commodities outside those funds. Thus the prices of many commodities that were formerly driven by the specifics of their own markets are now driven by investors who see an undifferentiated commodity asset class as a component of their portfolio management. So the price of wheat, for example, may at times have little to do with either farming or eating.

our key hypothesis:

  • Due to the increasing presence of commodity index investors after 2004, there is an increasing trend in the return correlations of non-energy commodities with crude oil, and the increasing trend is more pronounced for commodities in the two popular commodity indices: the S&P-Goldman Sachs Commodity Index (GSCI) and Dow Jones-UBS Commodity Index (DJ-UBS). …

Figure 3 depicts the average one-year rolling correlations among the 19 indexed commodities and the nine off-index commodities that have futures contracts traded in the US; indexed commodities are the ones which are listed in at least one of the GSCI and DJ-UBS indices. The two average correlations stayed at a stable level below 0.1 throughout the 1990s and early 2000s and were indistinguishable from each other. The average correlation among the indexed commodities climbed up to an unprecedented 0.5 in 2009, while the off-index commodities have only mild increases in correlation. This sharp contrast supports our hypothesis.
