Beware Of The Muppets In The Oil Market

The following chart shows the West Texas Intermediate (WTI) crude oil spot price in US$ (source: US Energy Information Administration).

Obviously, there was a speculative bubble from early 2007 to mid 2008 which then collapsed during the second half of 2008. In a series of articles, Chris Cook claims that the crude oil price has been in another bubble since the end of 2009 and that this bubble is just beginning to pop. The present article is an attempt at understanding the mechanics underlying Chris Cook’s ideas.

Negative Lease Rates Revisited

The Gold Lease Rate (GLR) as reported by the London Bullion Market Association (LBMA) turned negative after the peak of the credit crisis in 2008. The GLR over 1,2 and 3 months stayed negative for most of 2009 and 2010.

Since nobody leases their gold without charging a fee, a negative GLR seems to be nonsense. So how come the LBMA reports consistently negative GLRs?

We show that in an efficient market, the GLR as reported by the LBMA is equal to the risk premium for the case that the leased gold is not returned minus the storage fees for the gold, and so it can indeed come out negative.

Another possible answer is that LIBOR may have been rigged. As of a week ago, US, UK and Japanese authorities were investigating several banks for allegedly having manipulated LIBOR, the London Inter Bank Offered Rate.

Backwardation in the Case of a Monetary Metal

Silver has been in backwardation at the LBMA according to the published SIFO (Silver Forward Offered Rates) since January 19, 2011. It has also been in backwardation at the COMEX (New York Commodity Exchange) since around February 7, 2011. Figure 1 shows the LBMA Silver Forward Offered Rate from November 22, 2010, to May 19, 2011.

I was dissatisfied with much of what has been written on this topic. This is an attempt of a better explanation.


I explain that silver should not be viewed as an industrial commodity that is consumed, but that one should rather view US$ and silver as a currency pair. If one takes this point of view, backwardation is not a market inefficiency due to a supply shortage, but rather indicates counterparty risk.

Update (27 February 2012): Backwardation is also possible if US$ deposits are subject to carrying charges or if nominal interest rates are negative, see Red Alert Update.
