Has Peak Oil, as a meme, "tipped"? Our latest oil price poll suggests that well over 70% of the sample (N>3000 now) thinks that oil will at least stay above $114 a barrel for the next two months--and almost half think it will hit $140 a barrel in that timeframe. Search volume on Google for the term is up dramatically in the past month, as is traffic at The Oil Drum. One indicator of a "tipping point" for acceptance of Peak Oil may be the state of backwardation in oil futures. I first raised this idea over 2 years ago, but recent market movements, coinciding with attention in the press, may be validating it: when the markets accept Peak Oil, we will see the end of backwardation in crude oil markets, and possibly even Contango. Here's what has happened over the past 6 weeks:

UPDATE: Graph updated with data as of 10:00am EST on May 19th to show significant contango

Introduction

The world’s oil supplies are not unlimited. Unless the abiogenic theory of oil is correct, then reserves will one-day dwindle, and production will decline. New barrels cannot be “magic-ed” by some trick of economics. Extraction of any fossil fuel extraction is limited. Peak oil is inevitable. Of course, there is debate about when production hits its highs; it may have already happened, perhaps it will come in the next few years, and just possibly, it will be in 2020 or later. But make no mistake about it, we are not endowed with infinite amounts of the stuff.

Sceptics rightly point out that this bell has been rung before. In the mid 1980s, world oil reserves were forecast to last about 20 years; and yet here we are in 2007, with near record production levels. Historically, we have always found new sources of oil – in Alaska, in the North Sea, in the Gulf of Mexico, and off the coast of Africa – to satisfy our addiction. There are prospects in the future too: there may well be (very substantial) new discoveries in the Middle East, ultra-deepwater drilling holds promise, as does the development of new areas such as the South Atlantic, and increased enhanced oil recovery will certainly play a role. This misses the point: finding new oil reserves may push out peak production, but it does not invalidate the concept. Our planet does not contain an unlimited amount of oil.

Many – particularly on this site - argue that economics has little that is intelligent to say about peak oil. Yet the very definition of economics is the study of scarcity, and in particular, the study of the efficient allocation of scarce resources. What more relevant subject could there be for studying the effects of peak oil?

On October 24th, Dr. James Hamilton of Econbrowser commented on The Tragic Consequences of the High Discounting of Oil Extraction [1] in his story Is peak oil irrelevant?

If Dave had gazed not at a century of prices but rather at just the last 15 years of the price of oil relative to the PCE deflator, would he have drawn the same conclusion? If all we had was the graph above, it would seem quite natural to conclude that a rising scarcity rent could well be one factor in the recent behavior of this commodity price...

... I am not at all prepared to dismiss the hypothesis that scarcity rents have indeed started to make a contribution to oil prices over the last five years, and will become more apparent over the next five...

Admittedly, if the oil price should fall from here down to $30, then I'll have to conclude that scarcity rents have had nothing to do with the recent price moves.

But if Dave is right about the geology, oil is not going to $30.

Not knowing of any good evidence to contrary, I'll just make the simplifying assumption that I'm right about the geology.

We'll return below to some of Hamilton's other observations as we consider what meaning to draw from the history of oil prices over the last several years.
