Are high oil prices pushing us towards debt limits?

The US is reaching debt limits because of a specific resource limit – lack of inexpensive oil, Tverberg writes.  

(Page 2 of 5)

Ultimately (which may not be very long from now), the debt system appears likely to collapse. The Quantitative Easing (QE) which a number of governments are now using to hold down interest rates and make more funds available to lend cannot continue forever. While there are claims that QE is a bridge to “when growth returns,” it is seriously doubtful that economic growth will ever return. Inexpensive oil is simply too essential to today’s economy. As oil prices rise, wages fall, and demand for oil is further constrained. Falling wages also reduce demand for debt, as payback becomes more difficult.

How Household Debt Adds to Spendable Income

One thing readers may have not thought about is that it is the increase in debt that adds to a person’s (or company’s) spendable income. For example, taking out a car loan allows a person to buy a car. Paying back the loan over a period of years tends to reduce spendable income. If, in the aggregate, the amount of debt outstanding starts decreasing each year, spendable income is actually reduced below the level of wages, because in total, the balance is being reduced.

If we add the increase in household debt (mortgages, credit cards, student loans, car loans, etc.) to wages, this is the pattern we see historically. (The increase has been adjusted for inflation using CPI-Urban):

The pattern is very much what we would expect, given what we know about recent debt patterns. The amount of debt rose rapidly in the early 2000s,  when interest rates were lowered and lending standards relaxed. Some people bought new homes. Home prices escalated, with the higher demand. Many homeowners were able to refinance at lower interest rates. In the process, homeowners were able to “pull out” funds that they could use for any purpose they liked–fixing up the house, buying a new car, or going on a vacation.

By 2008, the party was over. In fact, the amount that was added through debt started decreasing in 2006 and 2007, after the Fed Reserve raised interest rates, in an attempt to choke back inflation caused by high oil prices. I talk about this in Oil Supply Limits and the Continuing Financial Crisis, available here or here.

Increased Government Debt Can Also Add to Spendable Income

In Figure 5, we added the increase in household debt to wages, to get an estimate of spendable income, adjusted for debt. Theoretically, at least part of the increase in government debt might also be added to spendable income, since it is often used (in leu of increased taxes) for programs that benefit citizens. (Some of the increased debt is used for things like bailing out banks, which is of questionable value in raising the spendable income of individuals, so perhaps not all of the increase in government debt should be added in estimating spendable income. Also, increased interest costs related to higher debt amounts would tend to have a dampening effect on spending, if interest rates are not continually dropping, as they have been under QE.)

If we add the increase in government debt (all kinds, including state and local) to the amounts shown in Figure 5, this is what we get:
