High Oil Prices and Recessions

The idea that high oil prices cause recessions shouldn’t be any surprise those who have been following my writings, or those of Dave Murphy, or those of Jeff Rubin. Yesterday, though, the Wall Street Journal finally decided that to mention the idea to its readers, in an article called “Rising Oil Prices Raise the Specter Of a Double Dip“. The quote they highlight as a “call out” is

When Consumers spend more at the pump, they often cut back on discretionary purchases.

The WSJ shows this graph, linking oil price hikes to recessions:

Oil Prices and Recessions
Figure 1. Wall Street Journal graphic showing connection between oil price rise and recession.

A Financial Times blog by Gavyn Davies says something very similar:

Each of the last five major downturns in global economic activity has been immediately preceded by a major spike in oil prices. Sometimes (e.g. in the 1970s and in 1990), the surge in oil prices has been due to supply restrictions, triggered by Opec or by war in the Middle East. Other times (e.g. in 2008), it has been due to rapid growth in the demand for oil.

But in both cases the contractionary effects of higher energy prices have eventually proven too much for the world economy to shrug off.

In this post, I explain what the WSJ and Financial Times articles are missing regarding the connection between oil and the economy. I also explain how the inability of oil prices to rise very far suggests that the downslope may be considerably steeper than most models based only on the Hubbert curve would predict.

Impacts of High Oil Prices on the Economy

The graph shown in the WSJ is very familiar. On November 5, 2008, I wrote a post called Jeff Rubin: Oil Prices Caused the Current Recession that included this graphic from this publication of CIBC World Markets.

Jeff Rubin - oil prices and recessions
Figure 2. Jeff Rubin's graphic showing connection of oil prices and recessions.

There are several reasons for the recessionary impacts.

Cutbacks in Discretionary Spending. If a person (or state government, or other organization that cannot easily pass through its costs) faces an increase in oil costs, it has a tendency to cut back in discretionary spending, since many oil expenditure are for necessities, like commuting to work. This is an exaggerated graphic I put together in a post I wrote called There is plenty of oil but . . . showing that because most incomes do not rise when oil prices rise, there is a compression in discretionary spending.

Oil Price Rise and Discretionary Income
Figure 3. Exaggerated graphic pointing out connection between oil price rise and discretionary income.

In Figure 3, I combine food and oil prices, because food prices tend to rise at the same time as oil prices. This occurs because oil is used very extensively in raising crops (operating farm machinery, herbicides and pesticides, irrigation, fertilizer) and in food transportation and packaging. A comparison of FAO’s Food Price Index and Brent oil prices (spot prices from the EIA) shows a high correlation:

World food price and brent oil price
Figure 4. Comparison world food price index and Brent oil price shows very similar trend.

Interest Rates and Inflation Rates. Higher oil food prices directly affect the inflation rate. Furthermore, if prices of other types of goods rise because of higher transportation costs, this also tends to raise inflation rates.

In the 2004 -2006 period, when oil prices rose, the Federal Reserve raised target interest rates, from 1% to over 5%, specifically mentioning rising oil prices, and their expected impact on inflation rates as a problem. To the extent that these higher interest rates affected consumer loans, the higher interest costs also acted as a reduction to income, over and above higher food costs.

The WSJ doesn’t seem to think that the Federal Reserve will again raise target interest rates this time. The WSJ reports:

In part because it is driven by something other than increased demand, the rising price of oil is unlikely to prompt the Federal Reserve to move more quickly toward raising short-term interest rates, now near zero, or otherwise moving to tighten credit. That could change if higher energy and goods costs begin to seriously feed into prices of other goods and services. But with unemployment high, a large share of U.S. manufacturing capacity still idle, and little sign that public or market expectations for inflation are moving up, Fed policymakers see the chances of inflation rising by more than their informal target of about 2% this year as remote.

Of course, it isn’t necessary for the Federal Reserve to raise target interest rates in order for interest rates on debt to rise. If investors can see that inflation is heating up, they will demand higher interest rates to compensate for the higher expected inflation rates. CNN Money shows the chart shown in Figure 5 in a February 7 article titled Bond shoppers: 10-year yields pushing near 4%.

Interest rates and Treasuries
Figure 5. CNN Money graphic showing rising interest rates affecting 10-year treasuries.

These higher interest rates on 10-year treasuries tend to translate to higher rates for other types of loans, such as mortgages, as well. So interest rates seem already to be headed higher, perhaps in part reflecting the inflationary impact of higher oil prices over the past year.

Decline in Home Prices. Another type of discretionary purchase is the purchase of a home. A person needs to have considerable discretionary income to purchase a more expensive home.  So cutbacks in discretionary income tend to reduce demand for homes, and because of this, home prices tend to drop.  Figure 4 shows that oil prices started rising in 2004. The timing of the 2006 -2007 home price drop matches very well with what a person might expect, based on the 2004-2006 oil price rise and the interest rate rises that followed the run-up in oil prices.

Debt Defaults. If oil and food prices are higher, some of the more marginal buyers are likely to find it difficult to keep up their payments, and miss payments. In the 2006-2007 period, many of the more marginal home buyers were holders of subprime loans, but there are many others as well. Businesses facing cutback in buying because of reduced demand for discretionary good are also likely to be affected by reduced demand, and find it difficult to pay their mortgages.

Eventually, banks figure out that loan applicants are likely to have a hard time repaying their loans, and cut back on offering credit because it doesn’t make sense to offer loans to people (and businesses) who are likely not to be able to repay them.

Balance of Payments. If oil prices rise, balance of payments are likely to get more out of balance than otherwise, with oil sellers benefitting from the higher oil prices.

What oil price level is needed for recession?

The WSJ article linked above says:

Most economists reckon that the price of oil would have to rise to at least $120 a barrel, and stay there, to threaten the recovery.

It is not clear how good an estimate we can expect from economists regarding when oil can be expected to affect the economy. The question of oil prices has only recently begun appearing on the radar screen of most economists.

One factor that may make recent estimates too low is the recent disparity between West Texas Intermediate oil prices and Brent prices. Most US analysts follow West Texas Intermediate (WTI) oil prices. These are the oil prices shown in Figure 1. WTI prices are now depressed relative to most other oil prices, as I discuss in this recent post, because of processing/shipping issues in the US Midwest. Another oil index, Brent, which many think is more representative, i$114 barrel now. So while WTI prices are “only” at around $100 barrel, other more representative oil indices are already higher.

Relationship between oil prices and recessions
Figure 6. Figure by Hall, Balogh, and Murphy showing relationship between oil price and recession.

Furthermore, other analyses show lower oil prices can lead to recessions. Charles Hall, Steven Balogh, and David Murphy did an analysis of the connection between the price of oil and when recession can be expected (Figure 6). In their view, recession is likely when oil amounts to more than 5.5% of GDP. When their analysis was done in 2008, this corresponded to a price of about $85 barrel.

If rising oil prices leads to recession, what are the implications for future oil supply?

If there were no problem with oil prices leading to recession, prices could keep on rising as much as they need to, to encourage additional production and to encourage alternatives. It is the fact that high oil prices cause recession, and the fact that recession tends to causes oil prices to drop, that prevents oil prices from continuing to rise, in a fashion that would allow oil companies, and makers of alternatives to be able to rely on the higher prices. This hampers the continued growth of oil supply.

If we think about it, extracting oil requires investment at many steps along the way: whenever exploration is done; whenever a new well is drilled, or “fracking” is done; when a decision is made to replace a broken oil and water separator; even when decisions are made to hire and train new staff members. As long as oil prices are rising enough that there is an adequate gap between the cost of production and what the oil can be sold for, there is the possibility that there will be enough funds left to reinvest.

In terms of Charlie Halls “cheese slicer model,” if the Energy Return on Energy Invested (EROI) is high enough, there will be enough energy coming out of the red arrows of Figure 7 for both (1) New Investment in Oil Extraction and (2) Demand for New Products that Use Oil. (See Nate Hagen’s post, At $100 oil, what can the scientist say to the investor?)

Re-investment Process
Figure 7. Charlie Hall's Cheese Slicer Model, showing arrows for various components of the reinvestment process. This version is theoretically for 1970.

On Figure 7, there are two red arrows. The one pointing to the right is the one relating to discretionary spending, and the one pointing down is the one for reinvestment. What happens is that over time, the easy-to-extract, high EROI oil, is depleted, and it takes more and more energy the extract the remaining oil. As the EROI declines, the size of the investment for new oil extraction keeps going up (the black arrow across the bottom gets larger).

Barklay’s recently illustrated their view as to how much the cost of oil production is increasing (Figure  in a publication called The Return to Scarcity.

Cost per barrel of oil production
Figure 8. Barklay's estimate of the cost per barrel of oil production.

A rise in oil cost of production generally corresponds with lower EROI. I don’t know whether Barklay’s analysis is precisly correct, but it is clear that the cost of oil production has been rising, both in dollar terms, and in energy required to produce the energy we are using. What happens when increasing energy is required to produce oil is that the amount of energy coming out of the red “discretionary use” arrows becomes less and less, so the arrows become smaller.

Cheese slicer model
Figure 9. Charlie Hall's Cheese Slicer Model, as of 2030.

As the red arrows denoting discretionary output become smaller (compare Figure 9 to Figure 7), the need for investment (big black arrow at the bottom) becomes larger, causing a serious conflict between what is needed for investment, and what is available for investment.

It seems as though we may already be reaching this point of conflict, especially if oil prices do not keep rising. We have been able to disguise this conflict in the need for investment funds partly through borrowing, but if credit restrictions associated with recession occur, it will become increasingly difficult to find adequate funds for investment.

The small arrow to the right for discretionary purchases (for Figure 9, compared to Figure 7) indicates that there is a constriction in demand for goods of all kinds (including those using oil), because the system of extracting oil uses so much energy itself. If the red arrow to the right were bigger, it would denote higher demand for goods and services, even goods and services made with expensive oil. But with weak demand, we get recession, rather than demand for goods produced from high-priced oil. At times, this lack of demand may manifest itself as a glut of high-priced oil on the market, because people can’t afford it. The net effect of all of this is that the lack of energy “push” from the red arrows is what brings the system to a halt. This may look like a lack of “oil demand” to economists.

The way I visualize the situation is to think of oil resources as a triangle, with the easiest to extract at the top, and the most difficult to extract at the bottom. These resources would include both conventional and unconventional oil. These resources would also include oil that can be gotten through very advanced (and expensive) extraction techniques, as well as oil that can be extracted very simply (and cheaply).

Economic and Non-Economic Resources
Figure 10. Schematic diagram of economic and non-economic resources

Right now, many people assume that all of the oil resources that we can “see” will eventually be economic. But if prices cannot rise high enough, then there is a limit on which of this oil can be extracted. It is not obvious from just looking at the available resources where this might be, but the limit is there. For example, if the limit where the economy goes into recession is $120, and if a particular “high-tech” extraction method needs a price of $140 to be economic, then that approach is not going to be economic, and what looks like usable oil resources using that method is likely to prove to be a mirage. Technology improvements may cause some oil extraction to move above the line, that would otherwise be below the line, and lack of investment funds may cause some oil to move below the line.

Many people see Hubbert’s Curve as predicting a peak and slow decline, based on M. King Hubbert’s analysis of how individual reservoirs depleted. It seems to me that Hubbert’s analysis more or less says what will happen to conventional liquid oil, extracted using low tech methods. But it really doesn’t tell us much about how much oil from lower quality sources or extracted using more and more advanced techniques will prove to be economic. The cutoff really takes place when prices are not high enough relative to production costs, so that there are not enough funds for investment and to support continued demand for energy-using products by consumers.

Once we start reaching economic limits (marked by serious recession and inadequate funds for reinvestment), we are likely to be well past the point where 50% of the oil that is economic to extract has been removed. Lack of funds for reinvestment can act to cut of future development fairly quickly, it would seem to me. If prices are not very high, say $60, much of the more expensive oil production will cease.

It should be noted that this model is not really complete. There may be other types of limits in addition to the cutoff relating to what is economic. We are hearing about the possibility of the breakup of Libya and damage to oil fields. To the extent that political turmoil makes it impossible to extract oil, then even what appears to be economic in Figure 10 may prove to be impossible to extract.
