Two Malthusian scares

Carter lectures the U.S. 
on energy, 1978
In 1798. the Reverend Thomas Malthus wrote his influential essay on population, arguing that population grows exponentially while the supply of food, energy, and other commodities only grows linearly.  As a result, the vast majority of humankind is doomed to be mired in poverty unless some even grimmer reapers than starvation (war, disease, etc.) are brought to bear, or births are moderated.  In 1978 U.S. president Jimmy Carter, reflecting a popular intellectual Malthusian sentiment of the time, sat by his fireplace in a comfy sweater and instructed Americans to turn down the thermostat lest we run out of oil.  (Here's a similar speech he gave a year earlier).

Malthus' description of a general pattern of human history (and indeed of the history of all living things, an observation that inspired Charles Darwin) was by and large accurate.  But since the time of Malthus, writing during the early industrial revolution, developed and even most developing economies have managed to trot or even race ahead of Malthus: per capita income has increased tremendously far beyond the near-starvation limits set by Malthusian theory.  Industrial productivity has pulled vastly increased amounts of commodities from the earth, using them to produce an unprecedented abundance of goods. Meanwhile population growth has radically declined until today many developing economies have below-replacement birthrates. Nevertheless, Malthus' observations and reasoning periodically stage an intellectual and popular comeback: industrial civilization can only cheat Malthus so long, thought leaders warn us; if we do not mend our unsustainable ways, and convert from gluttony to stringent conservation, Malthus' grim formula will soon return to wreak an awful revenge.

What chemical inputs does life depend on most?  Hydrogen and oxygen from water is plentiful. Plants obtain copious carbon by breathing in carbon dioxide (and animals from eating the carbohydrates, fats, and proteins in the plants or other animals). Nitrogen-fixing bacteria (and legume plants that are symbiotic with them) obtain plenty of single-N nitrogen by splitting the plentiful but strongly bonded N2 in our atmosphere.  Artificial means of nitrogen fixing depend primarily on natural gas or oil prices. Metals are plentiful in soil. The only significant remaining scarce ingredients for crops are potassium (K) and phosphorous (P) -- and of these on land phosphorous, which must be available in the form of phosphate, is the most needed and most lacking of all.  No technology can substitute anything else for phosphate: it has to be phosphate in order to form DNA, the essential cell energy molecule ATP, and crucial parts of our bones and teeth. Phosphate is thus the most geopolitically important agricultural input and exhibit A in Malthusian warnings about limited resources and unsustainable practices.  This also makes phosphorous a favorite target of stockpilers and speculators during a Malthusian scare.

The most important commodity for mining, manufacturing, and especially transportation, for almost all the 20th century and through the present time, is petroleum oil. Internal combustion and other engines powered by fuels refined from petroleum have since the early decades of the 20th century increasingly dominated he transport of goods and people on air, sea, and land.  For much of the late 19th and 20th centuries heating was a major use of oil; in that use it is being eclipsed by its cousin carbon fuel, natural gas. Oil is also the world's most important feedstock for the production of plastics, synthetic fibers, and a wide variety of other chemicals. While oil makes up a much larger price value of trade than phosphates, oil in the long run is potentially far more vulnerable to substitution innovation. And as we shall see, it also has been at least somewhat more amenable to technological improvements in supply.

Between the mid-1800s, by which time the industrial revolution had transformed much of Europe, and the end of the Bretton Woods era, sentiments about the unsustainability of industrial civilization were usually on the intellectual fringe.  But since the late 1960s, cries of doom and sophisticated warnings that we must redesign our economy, our technology, and civilization itself to "sustainable" lifestyles have become mainstream.  Malthusian allegations that we face diminishing, or soon-to-be diminishing, supplies of raw materials such as oil, natural gas, metal ores and fertilizers,  have become "common knowledge."

This component of green ideology has been fueled by two Malthusian scares: two substantial periods, the first between about 1968-1980, the second c. 2004-14, during which nominal commodity prices (i.e. the prices you see posted) increased dramatically,  and "real" (adjusted for some measure of inflation, such as the consumer price index) commodity prices increased substantially.  These price rises led to prophecies of a coming great diminution in our abilities to feed, cloth, and transport ourselves, much less to enjoy all the other abundant goods we have become accustomed to in the developed world as a result of the industrial revolutions that have occurred during and since the time of Malthus.  We faced a miserable future unless we changed our ways.  Unless we stopped having babies and stringently conserved and recycle our resources (the general green movement), or invest in solar power and electric cars (the Silicon Valley green movement), our future was deemed to be doom.  This remains a predominant ideology in Western culture today.

A big part of those scares and of the green movement has been environmental limits -- that we are damaging our environments, our planet, the one and only planet we can ever hope to naturally inhabit in the foreseeable future, far too much -- adding too much sulfur dioxide, ozone, or carbon dioxide to the atmosphere, too many fertilizers to our waterways, etc.  This essay does not address those concerns, which provide a far stronger argument for the sustainability movement than the topic of this essay -- the supply of commodities, especially of raw minerals from the earth such as oil, metal ores, and fertilizers, and the theories that have become popular since the late 1960s that historical rates of industrial growth cannot be sustained in the face of expected future diminution of those supplies.  Indeed, if you are already scared by our ability to pollute our planet, after you finish reading this essay you should be even more scared. Our planet places no material limits on our ability to consume and pollute it. If we are to have such limits we must put them in place, politically, ourselves.  (As for me, I'm scared both by the prospects for greater pollution and by the fact that political solutions and hoped-for advances in technology, not natural limits, will be the only ways to address the threats of pollution. The greatest source of domestic disputes is fighting over the thermostat; I expect this trend will carry over to international climate disputes of the future...)

For many of us in the developed world, a future of higher prices for energy and other commodities does not seem like such big a deal as it once did: we already have more physical goods than we know what to do with, and cutting back to achieve more peace of mind now seems to take and be worth more effort than accumulation. While the better-off fractions of the developed world have by and large reached a level of satisfaction in their consumption of the abundance of goods made possible by the industrial revolutions, the poorer fractions and the developing world have not.

Nevertheless, during the Malthusian scares commodities did seem to grow much more expensive and scarcer -- and not just a few commodities but commodities in general.  Indeed, the prices of a broad range of industrial commodities went substantially higher, often much faster than the general inflation rate  -- a sure sign, according to traditional industrial economics, that industrial supply was being outstripped by consumer demand -- that we were getting approaching, often rapidly, Malthusian limits rather than moving further away from them as has been the general trend since Malthus.  During most of the years of the first and second scares raw material and food prices skyrocketed, practically across the board. Why was this happening, if not the predictions of Malthusians starting to come true?  Let's take a look at the scares, and the economic histories surrounding them, to find out. 

Prelude to the First Malthusian Scare

From ancient civilization to the late 1960s, civilization's money was generally defined by, and either consisted of or was convertible to, standard weights of precious metals. Even thousands of years before the invention of coinage, most fines in the earliest recorded code of laws were defined and paid in weights of silver.  While the role of precious metals in monetary affairs declined throughout the 20th century, with many episodes of fiat currencies untied to precious metals inflating and hyperinflating, under the post-World War II Bretton Woods system United States and its allies up to 1968 had a gold window whereby authorized high rollers (among them most other governments) could still cash in their dollars for gold at a promised official rate.  Under Bretton Woods most other free world currencies were pegged to the dollar.  So you could cash in your local currency for dollars, and (if you were an authorized high roller) your dollars for gold, all at committed official prices.

But Bretton Woods, depending on a single country to ultimately back the entire free world's money, was not financially sustainable.  It established the U.S. dollar as the free-world standard after World War II, when the the U.S. made half the world's industrial goods and held over half of its financial reserves. But the economies damaged by World War II quickly recovered, and agricultural and industrial revolutions spread to the developing world where economic growth greatly quickened.  While the U.S. economy in its own terms was thriving,  the relative U.S. role in the world economy declined as those of the rest of the world quickly rose from the ashes. By the mid-1960s the U.S. held only 16% of the world's financial reserves, and even less than that of its gold reserves.  Even though it promised to exchange dollars for gold on demand, the U.S. Federal Reserve issued more notes, and its banks more broadly issued more dollar credit, than could possibly be securely backed by its diminishing gold reserves.

Meanwhile, most academic and government economists scoffed at the gold standard as a "barbarous relic" and held that world monetary conditions would be improved if the U.S. stopped pretending that the dollar was pegged to gold.  By 1968 the U.S. was no longer willing to honor its commitment to deliver an ounce of gold for $35.  The U.S., which since the time of Franklin Roosevelt had banned the domestic private gold trade, now tried with futility to halt overseas private trade by refusing to deal in gold with governments that allowed private gold trade.  (In reality, this was less a serious attempt to stifle overseas private gold trade than an attempt to close down the gold window in a face-saving way).  The U.S. government forced the London Gold Pool, the gold window mechanism operating between the major free world central banks, to declare a "bank holiday", i.e. shut down its operations.  But of course this didn't stop non-Americans from trading in gold; quite the opposite: it signaled that the U.S. dollar, and all the currencies pegged to the U.S. dollar, had radically changed in form, and might no longer be as reliable as a store of value. The free-market price of gold soon rose well above $35 official rate. The U.S. was by 1971 forced to officially float the dollar (it had already been floating de facto for up to three years), officially making the U.S. dollar a purely fiat currency.  The pegged currencies followed suit, and Bretton Woods was dead.

All this monetary obscurity matters for our Malthusian scares not just because all the aforesaid commodity prices from then until now are quoted in major fiat currencies, most usually in dollars, and these signals prices send about industrial supply and demand can only be as reliable as the currencies those prices are denominated in. Such a consideration could, with good statistics based on good records, be reasonably dealt with by computing the "real", inflation-adjusted prices of commodities.  But commodity prices proceeded to skyrocket even in general-inflation-adjusted terms The dawn of the pure fiat, floating currency regime caused far deeper forces to come into play.

For in reality, post-gold-standard prices for industrial commodities are not driven purely, or often even mostly, by industrial demand being met by appropriate changes in material supply.  Instead, both supply and demand curves have been warped by a new role for the major industrial commodities -- they are no longer purely commodities; the are in part also money.  In particular, they have since the late 1960s been increasingly used as a liquid store of value, easily tradeable for media of exchange (e.g. dollars), as an alternative to and hedge for the new regime of floating rate currencies.

 Noise in the signal: radical increase in volatility of two of the most 
important geopolitical minerals, crude oil and phosphate, between the 
Bretton Woods  (1947-70) and floating rate (1970-present) eras.

What does it mean to say a commodity is part money?  For this we need to turn to economist Carl Menger's theory of the origins of money.  Menger's theory is less an accurate account of how money did historically originate among humans (which happened long before the dawn of the efficient commodity markets postulated by Menger), as a good theory and reasonably accurate set of predictions about how a free barter market economy does behave whenever it does arise.  According to Menger, in a world of market-based barter, a very high cost (which economists would now call a transaction cost) comes from having to keep track of on the order of N^2 prices for the N goods, and the lack of coincidence of mutual wants between the holders of any two particular such commodities.

For this reason market participants start spontaneously treating some goods as intermediate commodities.  Intermediate commodities are held, not to consume them, but to store value until the next opportunity for exchange comes along.  The intermediate commodity's price increases substantially from what it was when it was just demanded for its consumption: it obtains a price premium for its use as a store of value immune from the changing values of currency or currency-denominated assets the holder of the intermediate commodity would have otherwise held.  This price premium waxes and wanes with the weighted changes in inflation expectations of the world's main traded currencies.

Many commodities might be used this way: and every commodity that is used in this way becomes, in part, money.  It is no longer just an good whose supply is driven by purely by the costs of production (since producers may choose to withhold production rather than sell for a currency whose inflation expectations have just increased, or may choose to increase production beyond the needs of immediate demand when inflation expectations have decreased), or whose demand is driven purely by desires or needs for its consumption (since some of the demand -- the vast majority of the demand in the case of gold and silver -- is now for its use as a store of value). It is an intermediate commodity, partial money.

When the primary use of the commodity money is as a medium of exchange, for example the cigarettes used as money in some wartime prisons, strong network effects usually exist to cause the market to converge on one or a few standards -- historically, usually gold and silver.  These undergo a "bubble that does not pop". But the other intermediate commodities, the commodities don't make it all the way to being dominant and nearly pure money, are bubbles that can and do pop.

When the primary use of commodity money is, however, a store of value, a store of value that can be readily exchanged when needed for the actual medium of exchange, there is almost no network effect.  Any commodity that can be stored and so traded can be used as store of value that will render the owner immune from the perceived or actual risks of holding a floating currency. This storage could occur in the form of a paper or digital future, or as the actual commodity in the warehouse, or even as a readily extractable mineral such as oil still in the ground.

Since the end of Bretton Woods, the major industrial commodities, and especially the major geopolitical commodities such as oil and phosphates, have become Mengerian.  They are no longer purely industrial commodities.  They are also stores of value, places to put wealth in between obtaining money and spending it, that provide an alternative for those who wish to diversify away from, for various reasons, holding currency or assets such as bonds and derivatives that are defined by or correlated to the health of currencies.  In the face of increasing inflation expectations, stockpiling of commodities also decreases the risk that further economic growth that nations may be expecting or planning for in their economies could only come at the costs of even purchasing the needed inputs at even higher prices in the future (e.g. China in the 2000s). Stockpiling of commodities is also a general strategy whenever international trust erode and leaders start thinking of potential risks that trade will be slowed or embargoed.

There are other securities that can store and even grow value -- stocks, bonds, real estate.  In many ways all these are better stores of value than commodities.  However for a major financial and political power, they have drawbacks.  First, they are trust-based -- you are trusting somebody (often a foreigner) to pay the coupons or dividends.  In the case of real estate, it depends on the vagaries of local economic activity and politics. Commodities, especially commodities a government can physically control, are far more trust-minimized.  The U.S. can sanction Russia by freezing the assets of its national held in paper or digital form in the U.S., but it cannot take the oil from Russia's wells or stop it from drilling, pumping, and selling it to e.g. Europe.  Finally, commodities in most of their forms, especially as futures, are readily exchanged for pure money such as dollars. Since the theme of this paper is Malthusian resources, we shall focus on the waxing and waning of the intermediateness of commodities, and in particular the geolitical commodities oil and phosphate rock.

Thus industrial commodities, and especially minerals important to geopolitics like crude oil and phosphate, serve at least three major purposes in the post Bretton Woods world beyond just industrial or agricultural consumption:

(a) a hedge against increases in expected inflation in floating rate currencies, or greater uncertainties about same,

(b) for governments, protection against coercive economic sanctions by foreign governments, and

(c) for militarily strong countries, a form of wealth relatively immune from foreign attack in time of war

We will see all these factors at play during the first and second Malthusian scares.

The First Malthusian Scare

Oil "chasing the tail of gold" 
during the 1970s. (Source)

As described above, the Bretton Woods era ended between 1968 and 1971, leading to the purely floating rate regime that has prevailed from 1971 to today. Free trade in gold, which had been banned under Franklin Roosevelt, was returned to the U.S.

Shortly thereafter, in 1973-4, an event that many economists have deemed an "exogenous shock", and even a main cause of the dramatic oil price rises of the 1970s, occurred on the world stage: the Arab oil embargo of Britain and the U.S. in response to their intervention on behalf of Israel in the 1973 Yom Kippur War.  Around the same time OPEC more than doubled the dollar prices it charged for its oil.  It is common but highly inaccurate to call OPEC a "monopoly cartel" at that time -- it accounted for only about 3% of U.S. oil consumption in 1967 and still only 6.7% at the end of 1973.  It had increased its pricing power from negligible to slight; it could hardly have more than doubled the price of oil on its own had not other oil-producing companies and countries been of similar mind.

One dog didn't bark: oil prices around the times of the 
Suez crisis (1956-7), in which Europe lost control of over 
half its oil supply, and the Arab Crisis (73-74), involving a 
temporary embargo that was easy to get around 
by trading through cutout countries.
By sharp contrast, the Suez Crisis of 1956-7, which produced a much more dramatic and longer-lasting impact on the world's oil supply chains -- Europe suddenly lost military control over more than half of the oil it consumed to a recently independent and hostile Egypt, never to gain it back -- was followed by a far smaller and more ephemeral percentage increase in oil prices.

Due to the increased inflation expectations, oil producers conserved on pumping, despite rising prices and oil consumers stockpiled despite the rising prices of funding those purchases. The reverse would happen throughout the decreases in inflation expectations and resulting long decline in commodity prices during most of the 1980s and 1990s.  Oil producers kept pumping beyond the needs of the industrial market to hasten the drawdown of their depreciating reservoirs.

What the voter saw: U.S. consumer 
price index 1973-81.
But during the first Malthusian scare, U.S. and European entities began stockpiling oil and other strategic commodities. For example U.S. oil imports from the Middle East, which had been only about 3% of consumption in 1967 when relations were friendly, had increased to 6.7% by 1973 even though relations had become hostile. and nominal prices of that oil had risen. Meanwhile U.S. oil producers were pumping less oil, choosing to keep relatively more of it in the ground rather than sell it for cheapening dollars.

The Second Malthusian Scare 

As in the 1970s, the commodity rise during the second Malthusian scare of roughly 2004-14 was often sharp and concurrently effected the vast majority of commodities. After substantial advances in both real estate and commodity prices the previous several years, during 2007 central banks cut rates and raise money supplies to fight collapsing real estate prices. These efforts fueled sharp increases in inflation expectations. Nominal and CPI-adjusted prices of fossil fuels, precious metals, industrial metals, lumber, fibers, fertilizers, grains, oilseeds, dairy, and livestock all skyrocketed during 2007, hitting record highs in nominal prices.  The market’s endless search for stores of value independent of the vagaries of fiat currencies had switched from real estate on which easy loans were defaulting to commodities that could be held more securely.  This time the most (in)famous stockpiler was China, planning for the rapid economic growth it expected in the decades ahead.

Also as in the 1970s, the individual components of this broad-range trend were attributed to a stupendous variety of idiosyncratic causes -- the co-occurrence of which all driving prices in the same direction at the same time was astronomically improbable. The only reasonable attribution would be to related common causes – which, given that there had been no sudden worldwide industrial boom, had to have been monetary causes.

Warnings about peak oil, peak phosphorous, etc. issued from all the major media outlets and science journals.  In Silicon Valley, a boom in "green technology" startups and investments ensued -- resulting later in mostly bankrupt companies. 

As I wrote at the time:
It is a gross violation of Occam's Razor to attribute the recent very broad-based run-up in dollar commodity prices primarily to the plethora of disparate causes to which they have been attributed: "peak oil", the war in Iraq, ethanol subsidies displacing food, and so on. Rises in industrial demand, increases in the costs of transporting commodities due to high oil prices, and so on explain only a small fraction of the rise in other commodity prices, and do not explain at all why precious metal prices have increased alongside those of other commodities. Occam's Razor points us, as it did to wise investors and economists in the 1970s, to the one kind of commodity all these other commodities have in common: the currencies they are priced in...
...demand for the oft-dreaded but ill-understood "hoarding" and "speculation", that is storing extra commodities (often off-the-books, or at least not in the officially measured warehouses) and the purchase of extra commodity futures and other commodity derivatives to hedge transactions based on government currencies, will remain strong as long as the Federal Reserve continues to inflate the dollar supply, and as long as many developing countries continue to link their currencies to this dollar. Commodity prices in dollars will level off, and then move back down close to historical trends based largely on just industrial consumption, if or when the Fed stops increasing the supply of dollars faster than the demand for dollars.
As it transpired, neither the Malthusian worries nor, as of this writing, the inflation expectations proved justified.  The run-up in oil helped fund the fracking revolution, a technology which defied peak oil theory:

Theory: peak oil diagram after Hubbert.  Alleged to 
apply at all scales not just to individual wells.

Reality: not as simple as theory

Oil thus demonstrated itself as a poorer monetary substitute than gold: being a much more novel commodity than gold, its production is subject to substantially more likelihood of technological invention and geological discovery.   

Fracking in one diagram

This possibility, which had not been sufficiently priced into oil before fracking, makes oil supply less reliably scarce than that of gold, rendering it less useful as a store of value, reducing the monetary premium of the oil price over oil as it would be priced if it were just an industrial commodity. Secondly, of course, is the direct effect of fracking on the supply curve in lowering oil prices.  The effects of the fracking revolution are amplified because more than just the Econ-101 supply curve shift is reducing oil prices due to fracking: oil's monetary premium is being eroded at the same time. Oil had been a monetary bubble which is now bursting.

If you are Saudi Arabia or Iraq sitting on large reservoirs of easily extracted oi, your alternative to treating oil as a store of value, if you still don't trust the Western powers, is to pump even more and trade the proceeds for gold (and also pay off some foolishly acquired debts) -- which is what we now see happening. Thus, paradoxically (to those who analyze oil as no more than an industrial commodity) oil producing countries pump more oil despite much lower oil prices. They are selling oil from their "oil warehouse" below the sands of the Middle East in exchange for gold, which due to the fracking revolution has reasserted its superiority as a trust-minimized currency over oil. If "money is the bubble that doesn't pop", partial money, i.e. Mengerian intermediate commodities, create bubbles that sometimes do pop, as the desirability of various commodities for their monetary properties, especially their value as a store of value relatively immune from political interdiction, waxes and wanes.

As much good news as bad: the two Malthusian scares 
sandwich an era when inflation-commodity prices fell by about the same 
amount that they rose during the two scares combined. (And they have 
fallen further since 2010). The explanation of "tight money" vs. "easy 
money" is pertinent but oversimplified, as one would expect an 
attempt to explain a theory in chart labels to be...


During the Bretton Woods era the U.S. dollar, pegged to gold at $35 an ounce, served the entire free world as a common and reliable standard of value.  The transition from Bretton Woods to floating rates left the world with no common and reliable standard of value by which to guarantee future real returns on contracts or investments.  As a result the most commonly traded commodities, and especially geopolitical commodities such as oil and phosphates, became Mengerian intermediate commodities, with a price premium as a store of value that waxed and waned with the weighted expected inflation among the world's various floating currencies. As a result, the prices of these commodities are much more volatile since 1970 than they were during the Bretton Woods era. Epochs of increasing inflation expectations have led to rapid, broad-based commodity price rises, where the market gives out false signals of scarcity, leading to Malthusian anxieties and panics that we face a future of diminishing natural resources. This in turn has fueled a major and sustainable growth in green ideology since the 1960s.

It's no longer debatable that commodity supplies in general pose few limits to long-term industrial growth, nor, except in the special case of phosphates, any significant limits that cannot eventually be innovated past by substituting newer more abundant materials for scarcer older ones.  To obtain all the commodities we have consumed in history has involved barely scratching he surface of one planet. Scratching out somewhat more each upcoming decade and century into the foreseeable future is, in terms of that supply, by and large sustainable. A far more debatable proposition is to how much environmental impacts will or should limit industrial growth -- for example, what is or should be our ability to continue pumping more carbon dioxide into the atmosphere? That is a debate this paper shall leave for another day.

"Due to the increased inflation expectations, oil producers conserved on pumping, despite rising prices and oil consumers stockpiled despite the rising prices of funding those purchases."

This sounds a lot like Scott Sumner's narrative of gold hoarding during the Great Depression in his recent book, The Midas Paradox.

Though I agree in general terms with your essay (commodities as repository of value and that Malthus' ideas of scarcity aren't held up by history) I somewhat disagree on 2 points:

1. You state before FIAT currency the dollar had a "better" intrinsic value (better repository of value at least) shouldn't this drive inflation down when there were what you call "malthusian scares" (people "bought" and stored money raising its price relative to other goods)? Did this happen?

2. FIAT currency is unpegged from gold. Shouldn't this make gold an even better repository of value since it's no longer affected by the forces that drive currency markets? Why the need for other, potentially more volatile commodities such as oil as a repository of value?

Lourenço, great questions.

1. During the Bretton Woods era the Federal Reserve was run largely by Keynesian and similar economists who stimulated small (c. 3%/year) amounts of inflation, believing that was the optimal level for economic growth. This however, isn't compatible with pegging the dollar to gold, which in the long run would produce much closer to zero inflation, which they believed (and most economists still believe) would retard economic growth. This is another big reason U.S. gold reserves fell to financially unsustainable levels by 1968. The Federal Reserve was finally forced to choose between keeping the gold standard and keeping to their beliefs that some inflation is good, and they chose their beliefs (with however unintended consequences described above).

2. Here as elsewhere diversification across many commodities reduces risks compared to holding just one commodity. Also, you are sitting on a large reservoir of oil, you have no choice but between holding and pumping the oil to sell it for fiat -- which choice will in part be governed by inflation expectations. Similarly, if you are a country planning for a geopolitically secure economic growth, you choose between stockpiling and consuming your stockpiles, in part based on inflation expectations. Finally, if a bubble for a geopolitical commodity collapses you still have underlying long-term industrial demand to fall back on, which isn't the case if gold or silver collapses. So there's a good argument when hedging e.g. your fiat-denominated government bonds to use a mix of both precious metals and industrial commodities rather than just precious metals alone.

Great read!

But I have to point out that the Menger who wrote "On the origin of money" was Carl Menger, not his son Karl, who was a mathematician. Actually I don't know why jstor reports the name in that way but it's surely wrong, you can check on wiki.

If you are referring to hyperinflation this is a complete loss of faith in currency and is often event-based (e.g., war, major political change). Prior hyperinflations all had one common denominator: during a period of instability, spending was used as a political tool and it got out of hand. In other words, currency becomes worthless in a short period of time. Certainly this loss of faith has not happened, yet, in the U.S. or EU (China may prove to be different).

The Fed itself can't cause hyperinflation and more importantly would not if they could. The reason is "Hyperinflation Would End The Game"

Hyperinflation by definition would destroy the currency and thus the banks
Hyperinflation would destroy the wealthy and all their corporate bond holding
Hyperinflation would destroy the Fed
Hyperinflation would destroy the wealthy political class

To understand how powerless the Fed is, one needs to understand the difference between credit and money, how much the former dwarfs the latter, and what the Fed's role is in getting banks to lend.

If you are referring to much lower inflation rates such as the Fed (and other central banks) have targeted they tried to revive the credit markets but have essentially failed, except for student loans. Making debt slaves out of students is actually a hugely deflationary force.

Moreover, the Fed cannot give money away, spend it, or force anyone to spend it. That is a very tough battle for the Fed with attitudes where they are. Banks do not want to lend, credit-worthy businesses do not want to borrow, and consumers are still deleveraging or saving as much as they can due to retirement uncertainties. Those are extremely deflationary forces.

Most of the money created since The Great Recession sits as excess reserves. Even printing $50 trillion dollars tomorrow might not do anything. Indeed, if $50 trillion printed tomorrow sat as excess reserves (the most likely event), it would have the same effect as if it was buried in the ground, or not printed at all. Such is the nature of a credit-based economy, and a point that has caused hugely inaccurate inflation forecasts from many economists.

Such massive printing might briefly cause a temporary attitude change accompanied by a brief asset bubble of some sort (especially in long-dated treasuries given banks would put some of it to that use). However, massive printing would collapse treasury rates, further destroying those on fixed income, and make it even harder for pension plans to meet assumptions. Since printing $2 trillion did not spur credit expansion, pray tell why would $50 trillion?

The first two Malthusian scares were indeed unfounded, but I am not so sure about the third one, and by that I mean the current deflationary trend. According to Gail Tverberg, deflation (the inability to keep commodity prices high enough to encourage their extraction) is how peak oil manifests, right now, resulting in the imminent collapse of industrial civilization, and I don't see how this blog post or anything else debunks her ideas.

have different commodities prices become more correlated after Bretton woods?

"The first two Malthusian scares were indeed unfounded, but I am not so sure about the third one, and by that I mean the current deflationary trend. According to Gail Tverberg, deflation (the inability to keep commodity prices high enough to encourage their extraction)..."

If prices of product X aren't high enough to encourage extraction, then extraction slows down. Then, if demand for product X remains the same or increases, the price of X will rise. I don't see the problem there.

Of course, if the demand for X continues to fall even faster than the slowdown in extraction, the price of X will continue to fall. I don't see the problem there, either. If the demand for X continues to fall, even with falling prices for X, it can't be very important.

One of the best of your rare, and always excellent, posts. I wish you would post more but then you post when you have something to say. Minor quibble--if you post about phosphorus, spell it right.

The problem is that when a commodity is an essential ingredient in all economic activity, then there is a definite limit to how high the price of that commodity can go. This is the case with oil, for example. As long as oil is needed as a primary energy source to drive economic activity, then the price per barrel of oil can't rise above the value of the economic activity that can be driven by that oil. This manifests as lack of demand above a certain price, and when the cost of extraction has risen above this point due to depletion, oil can no longer be extracted and we hit the real Malthusian catastrophe.

Nick, if it were technologically feasible, wouldn't it be best to peg the quantity of a currency to the quantity of commodity infrastructure that falls under that currency's control? Currency quantity would represent legal access to infrastructure quantity. The legal right to infrastructure is divvied up among agents according to the governing algorithm that seeks an optimization goal such as expansion of the infrastructure, making it evolutionarily recursive.

Our thinking machines and brains move around electrons and ions to model the consequences of moving much larger objects in the external world. Computational infrastructure (CPUs, memory, and communication channels) is a mass that required energy in its creation (like commodity production, storage, and transmission infrastructure). Computation, memory changes, and communication require energy directly (like commodity production, storage, and transmission).

Evolution acquires more and more energy to move more mass to create more efficient cooperative/controllable computational systems to repeat the process. Commodity production infrastructure is then the phenotype for producing better brains to produce more infrastructure.

Markets are removing oxygen atoms from metals, metalloids, and carbon which creates denser materials with stronger bonds that are replacing bones, teeth, shells, brains, and photosynthesis. Humanity "began" the path of replacing outdated biology with "machines" by its use of rocks and currency to decide how to use the rocks. DNA crystals were the previously prevailing memory system for the algorithms which gave rise to brains, which gave rise to corporations and computers.

In agoric A.I., the optimization of the use of limited resources under constraints requires a macroscopic governing algorithm with a goal that issues a currency and its legal use to access thinking resources. These systems, still dependent on human direction, underlie global economics and governments, which retain the same character of optimization of governed limited resources via a currency representing the limited resources.

The optimization of a path integral under similar mass-energy constraints also occurs in quantum mechanics and it retains its character all the way up to global dynamical systems over all time scales (the least action principle is more fundamental than Newtonian, Hamiltonian, and Lagrangian dynamics). Thinking machines like brains and computers controlling governed economics seem like 2 stepping stones that connect quantum and large-scale dynamics.

Everyone loves the cigarette example; a more recent one is laundry detergent. http://nymag.com/news/features/tide-detergent-drugs-2013-1/

That is why I only trade the price action and technical patterns....they're a by-product of what people believe and how they feel- represent in real time all that is interpreted by opinions and experts on future expectations.

Why do drug sellers want detergent twice as much as cash? Vodka in the USSR breakdown was a good example. High food energy content in small package, lasts forever, divisible, common usable commodity, can't counterfeit.

Unknown: Thank you for your rich reply. I have read over it several times, along with the original blog post, in order to digest it all.

So regardless of the unprecedented ZIRP the bulk of the money created has been stockpiled instead of used by banks in their traditional role as FR money supply multipliers. I understand why banks may be reluctant to lend at ZIRP/NIRP but why is there no consumer demand for easy credit?

I find I agree that many people are still wary of the global financial system and the financial PTSD has not worked itself out yet. Like Depression-era folks we are socking the bills away under the mattress, and may continue to do so for a generation.

I also wonder if this is related to technological change, and software eating the world. ROI on tech investments can turn out to occur much faster and at a higher return, requiring considerably lower initial investment than other 20th century heavy industries.

Demographic change, also, with the younger generation choosing (or being forced to choose in the case of educational debtors) to forgo staple purchases such as cars and houses that were considered requirements to those of my generation.

China of course was a major factor in the commodities runup to fuel their expansion which is now cooling off, so there is a deflationary factor there.

Even if silly Helicopter money comes to pass it may also just go under the mattress or to pay off old debt.

Like the author mentioned, it is easy to point fingers at certain causalities, but hard to see the relative weightings of each, or any overarching megatrends.

I gained alot from this article and discussion. Thanks to all.

I suspect the monetization of gold, silver, oil and the like will give way to the vast superiority of cryptocurrency, probably Bitcoin and/or Ether (Ethereum).

I would guess that gold retains its monetary importance almost solely due to the terrible monetary policies of central banks. With the sane and rational monetary policies of cryptocurrencies, their vastly superior savings and transactional functionality over gold coins and bars as money (zero storage and transportation cost, near-instant payment clearing at any distance, etc.) will prove to be decisive over precious metals.
