Oil Prices, Inventories And The Slowing U.S. Production by Bill O’Grady of Confluence Investment Management

The Market

Over the past year, oil prices fell sharply into the first quarter, remained rangebound from January through March, rallied above $60 per barrel in the spring and early summer, and then slid to new lows in August. Recently, we have seen a sharp bounce in prices; in fact, it is the fastest recovery since August 1990, when Saddam Hussein invaded Kuwait.

Oil Prices

The decline from late June into late August is probably discounting the normal seasonal demand weakness that occurs after the summer ends. Refineries usually engage in extended maintenance during autumn which reduces oil demand. The recent rally looks like aggressive short covering. The sub-$40 lows will probably hold as the lower end of the trading range into early winter. From there, we would look for a retest of the upper end of the range. It is always important to remember that cartel markets tend toward trading ranges as the supply behaviors lead to price stability. We are probably entering a $60 to $40 dollar trading range. Could we break down below this range? Yes, because it isn’t clear that OPEC will take steps to defend that level. However, some of the recent rally was due to rumors that OPEC was considering steps to support the market. Around $40 dollars, demand would be expected to improve. So, for now, our stance is that we are creating a price range and until we see strong evidence to the contrary, we expect it to

Oil Prices and Inventories

U.S. commercial crude oil inventories remain elevated.

The above chart shows the five-year average of inventories to isolate the usual seasonal pattern. There are two primary inventory build periods, from late-September into November and from early January into the spring. Over the past year, crude oil prices have mostly anticipated this pattern, which partly explains why prices fell so hard in November last year but stabilized when the rebuild season began. Essentially, the market discounted the build. It is likely we are seeing the same situation now; essentially, the market is anticipating the autumn inventory build, which means that prices will remain stable even after oil stockpiles rise in the coming weeks.

Oil Prices

This scatterplot shows the relationship between oil prices and U.S. commercial crude oil inventories. The blue arrow shows August and the red arrow shows our projection for stocks with current prices for September. Current prices are much closer to the projected relationship. Of course, we will see crude oil inventories rise in the coming weeks as refinery maintenance begins. If we reach around 465 mb by Halloween, a reasonable projection, prices could retest the old lows. However, the winter storage withdrawal has the potential to take us back to the high end of the aforementioned range. Until the supply situation changes, we assume a rangebound market is the most likely outcome.

Slowing U.S. Production

Last quarter, we discussed our outlook for U.S. oil production based on rig counts. Although the DOE did revise its recent production estimates lower, production remains elevated. Again, as we noted last quarter, there has been a 27-month lag between changes in rig counts and changes in production.

This chart updates our U.S. production model based on rig counts. So far, the model’s forecast is working reasonably well.

Oil Prices

This simple model suggests that production growth will remain high into 2017. Will this model get it perfect? No. All models are prone to error, simply because there are a number of uncountable variables that will affect production. In this case, high decline rates for fracked wells may lead to a shorter lag. Tightening financing could have a similar impact. However, this model does make the case that a major drop in output may simply take time.


If U.S. production remains elevated, at least for a while, the only other way for prices to recover quickly and break out of the upper end of the range would be from OPEC production cuts. So far, Saudi Arabia appears committed to maintaining its market share policy. In two previous events, the 1986-87 and 1998-99 market share wars, Saudi Arabia eventually organized lower cartel production and lifted prices. In the latter event, Mexico and Russia promised to lower output but these actions provided little more than a veneer of non-OPEC cooperation.

The problem in this market share war is that the big, non-OPEC producer is the U.S. Like the U.K. in the 1980s, there is virtually no chance OPEC can negotiate lower American production. Only extended low oil prices will lower U.S. output; that condition probably holds true for Canadian output as well. The Russians will be open to talking about output cuts, but the odds of actual reductions are low. Simply put, if prices are going to be supported by production cutbacks in the short run, it will have to come from OPEC. At present, Saudi cutbacks would support Iran’s economy. Given that Iran and Saudi Arabia are historical rivals, an agreement is unlikely.

On the other hand, the First Gulf War was also about market share. Iraq, its economy ravaged by the Iran-Iraq War, asked OPEC for higher oil prices and was rebuffed by OPEC. In response, Saddam Hussein invaded Kuwait. From Hussein’s perspective, he had just fought a long, costly war that had essentially protected the Persian Gulf kingdoms from Iran, and when he needed help he didn’t get any. That didn’t necessarily justify his attack on Kuwait, but it does suggest that the high oil reserve/low population nations in the Middle East are potentially vulnerable to direct action to lift oil prices from the high oil reserve/high population nations, who need constant high prices to operate their economies.

In other words, how long will Iran allow the Saudis to keep oil prices depressed and fight them for market share? It should be noted that Saddam Hussein probably would not have invaded Kuwait if he had anticipated that the Bush administration would take determined steps to build a military coalition and oust his forces. However, the key question now is if a similar situation occurred today, would the U.S. be able to perform the same rescue? It is highly doubtful that Russia would approve of any military action in the region, which would remove the imprimatur of a United Nations resolution. Given the reluctance of the current administration to engage in large-scale military operations, an invasion of Kuwait today would probably not generate the same response seen in 1991.
