Both the stock market and oil prices have been plunging. Is this “just another cycle,” or is it something much worse? I think it is something much worse.

Back in January, I wrote a post called Oil and the Economy: Where are We Headed in 2015-16? In it, I said that persistent very low prices could be a sign that we are reaching limits of a finite world. In fact, the scenario that is playing out matches up with what I expected to happen in my January post. In that post, I said

Needless to say, stagnating wages together with rapidly rising costs of oil production leads to a mismatch between:

• The amount consumers can afford for oil

• The cost of oil, if oil price matches the cost of production

This mismatch between rising costs of oil production and stagnating wages is what has been happening. The unaffordability problem can be hidden by a rising amount of debt for a while (since adding cheap debt helps make unaffordable big items seem affordable), but this scheme cannot go on forever.

Eventually, even at near zero interest rates, the amount of debt becomes too high, relative to income. Governments become afraid of adding more debt. Young people find student loans so burdensome that they put off buying homes and cars. The economic “pump” that used to result from rising wages and rising debt slows, slowing the growth of the world economy. With slow economic growth comes low demand for commodities that are used to make homes, cars, factories, and other goods. This slow economic growth is what brings the persistent trend toward low commodity prices experienced in recent years.

The screws are being tightened on the debt-laden US shale industry

More U.S. oil and gas companies could come under financial distress in the coming months as crucial hedging protection begins to expire.

Many companies had locked in high prices for their oil sales last year, allowing them a degree of protection as oil prices collapsed precipitously over the second half of 2014. Few, if any, hedged all of their production though, so revenues declined along with the oil price. Still, with some protection, the vast majority of companies (aside from a tragic handful) have not missed debt payments and have stayed out of bankruptcy.

That could become an increasingly tricky feat to pull off. As time passes, more and more hedges are expiring, leaving oil companies fully exposed to the painfully low oil price environment.

“A lot of these smaller guys who had bad balance sheets have pretty good hedge books through full-year 2015,” Andrew Byrne, an analyst with IHS, told the Houston Chronicle. “You can’t say that about 2016.”

In fact, about one-fifth of North American production is hedged at a median price of $87.51 per barrel. Smaller companies rely much more heavily upon hedging as they are more vulnerable to price swings and are not diversified with downstream assets. Across the industry, IHS estimates that smaller companies had about half of their production hedged at a median oil price of $89.86 per barrel in 2015.

But as those positions expire, any new hedges will be linked to current oil prices, which are now trading around $45 per barrel (although prices are fluctuating with great intensity and ferocity these days).

More worrying for the oil and gas companies that are struggling to keep their lights on is the forthcoming credit redeterminations, which typically take place in April and September. Banks recalculate credit lines for drillers, using oil prices as a key determinant of an individual company’s viability. With oil prices bouncing around near six-year lows, more companies will find themselves on the wrong side of that equation.

Banks were more lenient in April when oil prices were a bit higher and many analysts expected prices to rise. This time around the pain is mounting and there will be a lot less leeway. Somewhere around 10 to 15 percent credit offered to drillers could be cut back on average, a move that could slash $15 billion in credit capacity, according to CreditSights Inc.

With other financial avenues cut off, indebted drillers could be left with no way out.

“Nobody is in good shape with oil at $39,” CreditSights Inc. analyst Brian Gibbons told Bloomberg in an interview. “Most energy companies are shut out of the debt markets. There are few companies that can get a deal done right now.”

An introduction to Peak Oil

Contrary to popular opinion we do not live in the Information Age. What we live in is the Oil Age. Look around you and you’ll have a virtually impossible task of trying to find something that isn’t tied back to oil – be it hip replacement surgery, the little pieces of plastic wrapped around the ends of your shoelaces, or the vast infrastructure that makes the so-called “Information Age” possible.

But not only is the relatively superfluous dependent on oil, but so is the very non-superfluous, such as food we eat. Not simply an issue of food being shipped around the world on the back of fossil fuels, the fact of the matter is that fossil fuels are used to plant and harvest our foods, and upon much else, the very fertilizers we spread on our fields are mined from the ground and even derived from fossil fuels themselves (the ammonia and urea we apply to our fields for nitrogen are products of nitrogen atoms paired in the air around us of which were split and combined with hydrogen from natural gas). Simply put, oil and the rest of the fossil fuels are the “lifeblood” of industrial civilization and our modern way of life.

Enter peak oil.
