Please bear with me, I don't mean to be facetious here. Now that oil is over $140/barrel and everyone has a theory about why the price is so high, I thought I'd join the party and throw in my two cents as well.
First of all, there should be little contention that the commodity index funds raise futures prices, since buying, holding, and rolling over futures is what they are mandated to do. The table below shows crude contract prices out to December of 2016 (as last Friday). The price increase appears uniform, i.e., the market is not expecting a decline anytime soon. Commodity index funds tend to buy only the near month contracts (An exception is USL which buys one whole year into the future), so we are probably seeing the combined effects from the index funds and other speculators who may either have a view of their own or are riding on the coattails of the index funds. For the sake of brevity I'll use the term "speculator" in the rest of this post to describe all those participating in the futures market (with no intention to take delivery) with no regard to their intended holding period or long/short bias.
From the above starting point, a divergence of opinion quickly appears. Some argue that the total new futures demand is comparable to the actual new physical demand from emerging economies, while other argue that since speculators never take delivery, the spot price is solely a function of supply/demand. I'm not going to be a referee in this argument, instead, I'm here to explore a dynamic that I have seen mentioned elsewhere: the possibility of suppliers withholding production due to stable anticipated future prices.
First, let's recap the facts:
- Speculators bid up futures, including long dated futures.
- Speculators don't take delivery. There may indeed be hedge funds out there think about doing exactly this just as there are rumors that hedge funds are looking into buying grain elevators. For now, I take the inventory reports at face value. This is a crucial point as we know that the futures market in gold and silver do influence spot prices since a significant portion of physical demand is for investment which depends very much on investor psychology.
The common refrain is that producers have an incentive to produce as much as they can given a flat futures curve in order to maximize the present value of total return. This is the case for, say a copper mine. Since while the spot price, production cost and cutoff grade of the mine might change, the actual copper in the ground is fixed in place. However, an oil field is a far more temperamental beast. If there's anything I learned from Matt Simmons' Twilight in the Desert, it's that the ultimate recoverable resource (URR) of any field is rate dependent, i.e., running too fast a flow rate decreases the URR. A crude analogy which is also the extent of my understanding is this: imaging an oil well as a giant straw, the production rate can be increased by increasing the well pressure, commonly achieved by injecting water from underneath the oil layer. However, if the pressure is too high, oil can be driven above the opening of the "straw" and form pockets that are hard to get at, not to mention the water that also gets pumped out. In an environment of stable future prices, it is entirely possible that the present value of a mature field is higher if current production is tapered in exchange for a greater URR. Thus there is potential for a self-reinforcing, running-away train of oil prices. Once again it's hard to lay the blame on either the speculators who bid up futures or the pre-existing tight supply/demand condition, since both are necessary for this vicious circle to occur.
What to do
We might be tempted to put a stop to "speculation" as several bills in the congress are promising to do. I doubt if any of them will have the intended consequences. For starters, speculative capital is mobile. If people can't speculate in Chicago or New York, they will do so in London or Dubai. The real losers will be pension funds who don't have the luxury of leaving this country. They will struggle to meet future obligations as the best asset class in an inflationary world becomes unavailable to them. They will have to be bailed out by tax payers. So while the politicians are still at it, they might also want to read this timely article on the one commodity on which speculation has been banned.
Going back to the title of this post, conservation, voluntary or not, is still the best option. A 10% rise in average auto mileage saves as much oil as the production of giant oil field. Futures price will come down when there is clear demand destruction. I even believe it's prudent to raise gas taxes. Politically, it's definitely a non-starter. I might even have surprised some readers since my thinking have been consistently libertarian. However, I'll argue that in this case there's no escaping paying the government, be it the US government now or the government of Iran, Saudi Arabia and Venezuela some time later. Who knows, it may even drive down gas prices.
