Something’s Got to Give…
September 2nd, 2009Eventually something has to give in the markets for oil and natural gas if the price ratio between the commodities is to return to its historic range. Or, does it? The current ratio of 21-to1, as expressed by $ per barrel of oil (bbl) divided by $ per thousand cubic feet of gas (mcf), is the highest ratio seen in a decade. Economists have traditionally paid attention to this ratio as oil and natural gas are substitutes for each other in the US utility and industrial sectors. When one of the commodities has become disproportionately cheap or expensive, manufacturers and utilities have switched over to the cheaper fuel. Historically, the price ratio between the two commodities has ranged between 5-to-1 and 10-to-1. This ratio is grounded in the fact that it takes roughly 6,000 cubic feet (6 mcf) of natural gas to equal to the energy contained in one (1) barrel of oil. In a perfect world, dual fuel capable utilities and manufacturers would switch to natural gas any time the ratio rose significantly above six (thus raising the demand for natural gas) and switch to oil any time the ratio dropped significantly below six. The fuels are not perfect substitutes for each other and each is subject to its own supply and demand forces; so the ratio never sits exactly at 6-to-1 for very long.

With an price ratio over three times the energy ratio of the two commodities, economists would normally expect market forces to bring the ratios back to something closer than normal either through an increase in natural gas prices, or a decrease in oil prices, or both. While that return to normal is likely to happen in the long run, in the short run the natural gas market and the oil market are marching to two completely different drummers.
- The natural gas market is responding to the market fundamentals. Aggressive drilling programs since 2005 and advances in horizontal drilling technology have increased domestic supply while industrial and utility consumption levels have cratered with the aggressive recession. The result is the price for gas have fallen from a normal seasonal range of $6 to $10 per mcf to less than $3 per mcf and storage levels have hit an all-time high. A mild hurricane season and winter could result in natural gas fields reducing production.
- The oil market is also responding to market forces, but forces of a completely different stripe. While demand for oil is down worldwide, the long-term expectation is for oil demand and prices to increase. This disparity (known as “contango”) between the current price of oil and long-term options contracts has made it profitable to park tankers filled with oil and delay delivery until a later date. The result of these delays is artificially inflated current demand for oil, which then leads to increased short-term prices, thus reducing the incentive to store the oil. The other factor affecting oil prices is that the average marginal cost of producing oil has risen substantially in recent years, which puts a floor under the price because producers remove productive capacity when the price of oil falls too low.
So, what are our expectations? There are a number of factors out there which could affect the markets either singly or in combination:
- One possibility is that so much oil gets “parked” for future delivery that it depresses prices when consumer and industrial demand for oil returns. Given the limited numbers of tankers that can be “parked”, this scenario does not reduce oil prices so much as it limits the rise in oil prices in the future for a very short period.
- If US industrial and utility production continues at reduced levels, then the price of natural gas stays depressed. We do not see natural gas prices recovering without these sectors starting to recover from the recession. Watch the Institute for Supply Management’s (ISM) monthly index numbers for a sustained change above 50. In particular, watch the ISM sub-index for employment. When employment grows we’ll know that industry has confidence in the economic recovery.
- Horizontally drilled wells provide the bulk of new production in the US. These wells have traditionally exhibited steep decline rates. Right now companies aren’t drilling enough new wells to fully replace current supply. The lack of current drilling will moderate supplies in the medium and longer term. However, without an increase in demand, the effect of reduced supplies will be limited. If demand increases sharply, then the natural gas price could spike.
We see these factors as medium and longer term issues. In the short run we don’t see the oil/natural gas price ratio returning to “normal” as long as the US industrial sector remains depressed and the market expects oil prices to return to higher levels. We do believe that the longer these two markets remain out of sync the more violent the “snap back” is likely to be in the end.
