Just In Time Oil
Changes in US oil inventories sometimes cause a sharp move in the price of crude. It makes perfect sense, even if it’s hard to tease out much of a statistical relationship from the data. Oil stocks, meaning oil held in inventory, have been falling since the early days of the pandemic when the collapse in demand left traders scrambling for places to store it. The most recent weekly data showed our inventories are the lowest in almost forty years.
The US Strategic Petroleum Reserve (SPR) has also been falling. Privately held inventories move based on economics, whereas changes in the SPR are a political choice. This was most notable a year ago when high gasoline prices prompted the Administration to release oil to avoid losses in the mid-term elections. Such sales have continued (see Crude Climbs The Wall Of Supply Worries).

So for different reasons, both privately held inventories and the SPR are falling. Historically the two moved more or less independently given their differing objectives. Now, both the Federal government and commercial operators are concluding they need to hold less.
Businesses generally hold inventories of the inputs they need for production and finished goods awaiting sale. Such decisions are made to smooth production lines. Oil has the additional motivation in that speculation on higher prices may increase inventories. And the Federal government has its own, non-commercial goals.

One way to think about inventory adequacy is to measure how many days of domestic consumption could be supported if output and imports stopped. It’s well short of a perfect measure, because it assumes all the oil in storage could seamlessly move to where it’s needed and be of the correct grade to be acceptable to the refineries or other users taking delivery. So the current ratio of total oil in storage divided by average daily consumption of 57 days doesn’t mean inventories could satisfy domestic demand for that long. It’s undoubtedly far less. But it is the lowest ratio on record, going back 37 years. We’re on track to find out what inventory level is too low. Rising crude will tell us we’re there. It may already be happening.
“Just in time inventory” has made manufacturing more efficient. Delivering inputs only when needed to an automobile factory reduces the needed working capital and improves profitability. The decline in privately held oil stocks in recent years combined with stable refinery runs shows a similar improvement in operating efficiency.
Increased domestic oil production reduces our need to hold inventories for energy security. We’re less reliant on imports but because US refineries can’t use all the light shale oil we produce, two-way trade brings in the heavy crude they’re designed for and exports lighter grades. We have enormous inventory underground, accessible when needed.
Domestic production is growing, but slowly. The Baker Hughes oil rig count is at 513, down almost 20% from its peak late last year. Current output remains just shy of the 13 Million barrels per Day record of November 2019.
Exxon Mobil (XOM) is operating 17 rigs, down from 65 four years ago. Energy companies are staying disciplined, unmoved by the recent run up in prices. “If you think about capital efficiency, and you want to make sure you’re thinking long-term about your business, moving [drilling rigs] up and down a lot is not a good idea,” said Jack Williams, a senior vice president at XOM.

Pipeline operators often complain about the difficulties with construction. The experience of Equitrans with Mountain Valley Pipeline (MVP) is perhaps the most famous example of the cost that endless environmental legal challenges can impose on infrastructure projects.
But renewable energy is more urgently dependent on permitting reform because future Infrastructure projects will be concentrated there. We mostly have the oil and gas pipeline network we need, which is why midstream companies are buying back stock and raising dividends.
Wind turbines and solar panels are built in remote, sparsely populated locations. They need long-distance, high voltage transmission lines to move power to population centers. Decarbonizing our energy systems means converting more demand to electricity.
A recent WSJ report showed that more than 10,000 energy projects were awaiting permission to connect to electric grids at the end of last year, almost all wind and solar. The SunZia wind project in New Mexico filed for permits in 2006 and just received the go-ahead to begin construction. America’s system of government creates many opportunities for NIMBY opponents to file legal challenges at the local and state levels as well as federal.
Consequently, 17% of our primary energy comes from carbon-free sources. Half of that is nuclear, which given public resistance is unlikely to grow much. Switching from coal to natural gas for power generation remains our biggest source of reduced greenhouse gas emissions. Ironically, court challenges to new energy infrastructure from environmental extremists represent a significant challenge to renewables.
