Oil and other commodity prices have recently been dropping. Is this good news, or bad?

I would argue that falling commodity prices are bad news. It likely means that the debt bubble which has been holding up the world economy for a very long time–since World War II, at least–is failing to expand sufficiently. If the debt bubble collapses, we will be in huge difficulty.
Many people have the impression that falling oil prices mean that the cost of production is falling, and thus that the feared “peak oil” is far in the distance. This is not the correct interpretation, especially when many types of commodities are decreasing in price at the same time. When prices are set in a world market, the big issue is affordability. Even if food, oil and coal are close to necessities, consumers can’t pay more than they can afford.
A person can tell from Figure 1 that since the first part of 2011, the prices of Brent oil, Australian coal, and food have been trending downward. This drop in prices continues into September. For example, as I write this, Brent oil price is $97.70, while the average price for the latest month shown (August) is $105.27. It is this steeper, recent drop, which many are concerned about.
We are dealing with several confusing issues. Let me try to explain some of them.
Issue #1: Over the short term, commodity prices don’t reflect the cost of extraction; they reflect what buyers can afford.
Oil prices are set on a worldwide basis. The cost of extraction varies around the world. So it is clear that oil prices will not match the cost of extraction, or the cost of extraction plus a reasonable profit, for any particular producer.
If oil prices drop, there is a temptation to believe that this is because the cost of production has dropped. Over a long enough period, a drop in the cost of production might be expected to lead to lower oil prices. But we know that many oil producers are finding current oil prices too low. For example, the Wall Street Journal recently reported, “Royal Dutch Shell CEO: Can’t deny returns are too low. Ben van Beurden prepared to shrink company in order to boost returns, profitability.” I wrote about this issue in my post, Beginning of the End? Oil Companies Cut Back on Spending.
In the short term, low prices are likely to signal that less of the commodity can be sold on the world market. Commodities such as oil and food are very desirable products. Why would less be needed? The issue, unfortunately, is affordability. Affordability depends largely on (1) wages and (2) debt. Wages tend to be fairly stable. The likely culprit, if affordability is leading to lower demand for desirable products like oil and food, is less growth in debt. Continue reading
