The history of wheat

History celebrates the battlefields whereon we meet our death, but scorns to speak of the ploughed fields whereby we thrive. It knows the names of the king’s bastards but cannot tell us the origin of wheat. This is the way of human folly.  –           Jean-Henri Fabre (1823 –1915) French naturalist and author

 Wheat, barley and rye can trace their origin back to Triticeae, a grass that grew wild in the Fertile Crescent. Wild einkorn and emmer are wheat’s earliest ancestors; they had seed heads that quickly broke apart in the wind, scattering the seeds and permitting self-sowing. Modern-day wheat is the opposite: the grains now stay on the stalks no matter how strong the wind.

Modern-day wheat did not benefit as much as corn from the Fritz Haber process of combining nitrogen with hydrogen to make ammonia. Until the middle of the 20th century, applying nitrogen as fertiliser on wheat made it grow taller and thicker, but it fell over in the wind and rotted. Wheat needed to be genetically improved to take advantage of the technological progress in fertilisers.

One of the first leaps forward occurred in 1935 when a Japanese scientist named Gonjiro Inazuka crossed a semi-dwarf Japanese wheat species with two American varieties to produce an improved semi-dwarf variety Norin 10. Unlike previous types, which grew to 150 cm, Norin 10 only reached 60–110 cm.

In the late 1940s, Orville Vogel at Washington State University took another step forward when he imported Norin 10 into the US and crossed it with other varieties to yield high-yielding, semi-dwarf winter wheat.

However, the revolution in wheat—and it was a revolution—occurred in 1952. Norman Borlaug took some of these new Norin hybrid seeds to Mexico and grew thousands of unique varieties. He couldn’t sequence the wheat’s DNA to figure out which genes caused these traits because that technology didn’t exist then, but he carefully noted each variety’s characteristics. His work paid off, producing new kinds of dwarf wheat that were rust-resistant and didn’t blow over (lodge) in high winds.

By the 1960s, Borlaug was travelling the world to spread the news. His first stop was Pakistan where wheat yields were around 360kg an acre. Mexican farmers were by then getting more than three times that. His major success, however, was in India.

When India became independent in 1947, the country produced only 6.5 million tonnes of wheat each year, and yields were around 663 kg per hectare. It was not enough to feed the Indian population, and the country largely depended on food-aid imports from the US.

In 1963, India was on the brink of famine. The government invited Borlaug to India to test his new varieties. His yields were four or five times better, and India’s farmers quickly took up the new breeds. By 1974, India’s wheat production had tripled, and the country was self-sufficient in food. India has never faced a famine since.

In 1970 Norman Borlaug was awarded the Nobel Peace Prize for enabling what came to be called the ‘Green Revolution’. He earned it.

World wheat production has more than tripled in the last sixty years, from 234 million mt in 1960 to 772 million mt in 2020. At the same time, wheat acreage has only risen 10 per cent, from 202 million hectares to 222 million hectares. Without Norman Borlaug, the world population would not have increased over that same sixty-year period from 3.0 to 7.7 billion. And what’s more, crop failures and famines would still be regular occurrences.

But it is not just the varieties of wheat that have evolved over the centuries; so too has the way humanity has sown, harvested and ground it into flour.

Ancient Egyptians sowed wheat by casting seeds into the mud after the retreat of annual floodwaters along the Nile. They then drove their cattle over the area to trample the seeds into the ground. Hand scattering of seed is still used today in many parts of the world.

Early farmers harvested their wheat with sharpened stones fitted into a wood or bone handle, but the introduction of iron and steel led to the sickle, a tool that is still widely used. Sickles are light enough to be used by women and children and allow wheat to be cut at any height so that they can leave the straw standing or cut it separately.

The sickle was so crucial in human development that the USSR put it with the hammer on its flag. The hammer represented industry, the sickle, agriculture.

The scythe was an improvement over the sickle with a longer blade at right angles to a long wooden handle. You can harvest wheat faster with a scythe than with a sickle, and you can stand upright while you do it. However, a scythe cuts the straw close to the ground, leaving it attached to the wheat head. A scythe is heavier than the sickle. But the scythe has again entered into our collective psyches with death portrayed as the Grim Reaper harvesting souls.

The first mechanical reaper appeared in 1831: a two-wheeled, horse-drawn contraption pushed a series of moving, scissor-like blades against the grain to clip it close to the ground. A rotating paddlewheel swept the stalks against the cutting bales, so they fell on a platform as the machine moved forward.

Once farmers had harvested the wheat, they spread it on a plot of hard ground or threshing floor. They then drove cattle or horses over the grain so that their hooves separated the wheat from the chaff. Winnowing, or tossing the mixture into the air, then allowed the wind to blow away the lighter chaff and the heavier wheat to drop back. The threshing machine later used fans to separate the chaff from the grain, mechanically doing the process.

As its name suggests, the modern combine harvester performs all these basic jobs in one operation. Hiram Moore developed the first version in 1834 and, by 1860, combine harvesters had cutting widths of several meters. In 1885, Hugh Victor McKay, from Australia, developed the first commercial combine harvester, called the Sunshine Harvester. It reduced the number of working hours needed to harvest one acre of wheat from 46 hours to 30 minutes. Today a modern combine can harvest 1,000 bushels per hour. That’s more than 27 metric tonnes.

Once harvested, wheat needs to be milled into flour, separating the outer bran and germ from the inner, more digestible, endosperm. Although wheat has been grown for thousands of years, humans’ teeth from excavated villages dating back to 6,700 BC show no signs of wear, indicating that those early people already milled wheat. Archaeologists have found grinding stones at sites of ancient settlements in almost all parts of the world.

Over the centuries, mills have been powered by men, horses, oxen, water, or wind, all geared to turn one stone against another. The Romans were the first to use waterpower for milling flour, in about 100 BC, and it remained a significant source of mill power. In 1870, most of the approximately 22,000 flour mills in the US were still water driven.

The politics of wheat

“No man qualifies as a statesman who is entirely ignorant of the problems of wheat.” Socrates

Socrates was right: The Roman Empire needed a steady supply of wheat to flourish. Grain made into bread was the most critical element in the Roman diet, and the city required between 150,000 and 250,000 tonnes per year to feed its population. Rome imported most of its grain supplies and distributed a ‘dole’ of subsidised or free grain, and later bread, to about 200,000 less well-off residents, about a fifth of its population.

The Romans initially imported wheat from Sicily and Sardinia but later centred production on Carthage’s ancient city, in present-day Tunisia. In the second century BCE, the Emperor settled 6,000 colonists near Carthage, giving them about 25 hectares to grow grain. Later, when Egypt became part of the Roman Empire, the country became its primary supply source.

The Romans shipped the grain by barge to Alexandria, where they inspected it for quality and loaded it on ships for Rome. They transported it into sacks, rather than carrying it loose in the holds; ships transported an average of 350 tonnes, although some had as much as 1,500 tonnes. The ships were sail driven, unlike the Roman warships propelled by oarsmen. Sailing times from Italy to Alexandria in Egypt might be as brief as 14 days, but returning to Rome would have taken as long as 70 days as the winds were adverse.

Centuries later, Britain depended on wheat imports from its empire to feed itself and encouraged wheat cultivation in Australia and Canada.

In 1846, the UK abolished the Corn Laws, a system of tariffs and other trade restrictions on imported food and grain introduced in 1815. (Remember, at that time the word ‘corn’ referred to all cereal grains, such as wheat and barley.) The government had introduced the laws to keep grain prices high and protect domestic farmers and (particularly) landowners.

The repeal of the Corn Laws was a decisive moment in British economic history. Their repeal lowered food prices, encouraged increased agricultural productivity, and freed up surplus labour to drive Britain’s industrialisation.

But the repeal didn’t just change England. As Dan Morgan wrote in Merchants of Grain,

“Parliament, with its stroke of repeal, …changed the world. Repeal of the protectionist system had opened England to the wheat of all the world, created incentives for the settlement of vast territories across the oceans, and established the conditions for modern international trade, with the new sea routes and modern trading empires.”

The pressure of cheap imports drove a steep decline in British domestic wheat production. At the same time, food became more affordable. Between 1840 and 1880, the cost of bread fell by half. By the end of the 19th century, Britain was importing 5 million tonnes of wheat per year, about 20 per cent of which came from Britain’s colonies: Australia (150,000 mt), India (300,000 mt) and Canada (450,000 mt).

On the other side of the Atlantic, early setters were dependent on imported flour from Europe, most often England, until they could produce wheat independently. Though corn saved the early settlements, many settlers didn’t like it. They baked a bread called ‘thirds’ which they added to the imported wheat flour: one-third wheat flour, one-third rye, and one-third cornmeal.

By the 1740s, the US was exporting wheat to England from the northern fields of New York, New Jersey, and Pennsylvania. The US grew in importance as a wheat exporter after the American Revolution when the great migration into North America’s heartlands, along with the railroads, opened up new areas for farming.

Europe desperately needed this production, notably when their harvests failed in 1790 and 1807, and later, in 1860–1862. The Napoleonic wars (1803 to 1815) and World Wars I and II also led to spikes in wheat imports.

Wheat not only fed Europe during our numerous wars, but it also provoked conflicts. Writing in The Silk Roads: A New History of the World, the British historian Peter Frankopan argues that the Nazis invaded Russia for its wheat. Paul Joseph Goebbels, Hitler’s Minister of Propaganda, wrote that the Nazis opened the Russian front for ‘grain and bread’, to capture ‘the vast fields of the east (which) sway with golden wheat, enough to nourish our people and all of Europe’.

We will never know, but some argue if the Nazis had never made that dash for Russian wheat—if they had never invaded the Soviet Union—they could have won the Second World War. Is it possible that we all owe our freedom to wheat?

The magic of wheat

“In the sweat of thy face shalt thou eat bread, till thou return unto the ground.” Genesis 3:19

Unlike corn or soybeans, humans, not animals or cars, are the most important in terms of the world demand for wheat. On average, animals only eat about 18 per cent of the world’s total production of wheat. This number falls to less than 4 per cent in developing countries but as much as 35 per cent in developed countries. As a rule of thumb, wheat works as animal feed when it is 10 per cent cheaper than corn, or when wet weather reduces its protein content to under 10 per cent.

Even though wheat acreage has increased only modestly, wheat is now grown on more land area than any other food crop: 222 million hectares versus corn at 196 million hectares and rice at 163 million hectares. In 2020, the world’s farmers produced 772 million mt of wheat, making it the second most-produced cereal after corn at 1.1 million mt. Rice comes in at third place at 500 million mt.

Wheat is still the world’s biggest traded agricultural commodity by volume. In 2020 world exports were 194 million mt, just ahead of corn at 184 million mt and soybeans at 170 million mt; little of the world’s rice production trades internationally: 45 million mt in 2020.

If you were to ask your guests at your next dinner party to list the top wheat-producing countries in the world, I bet that they would all get it wrong. They may guess correctly that the EU tops the list at 136 million mt, but few would know that China now produces more wheat—134 million mt—than any other country in the world. China’s farmers now grow about the same quantity of wheat as Russia (85 million mt) and the US (50 million tonnes) combined. India is the world’s third-largest producer at an estimated 107 million mt.

Your party guests may have more success with exporters. Russia is now the world’s largest exporter at 39 million mt, followed by the US at 27 million tonnes and Canada and the EU, both at 26.5 million mt. Ukraine comes in fifth on the list at 17 million mt. (All figures are for 2020.)

I can guarantee that none of your dinner party guests could name the world’s top wheat importers! Although Egypt used to supply the Roman Empire with wheat from the Nile valley, it is now the world’s largest importer at 13 million mt. Unsurprisingly, when you consider their large population, Indonesia comes second at 11 million. China imported nine mln mt of wheat in 2020, while Turkey comes fourth at 8 million mt.

Wheat is an essential source of carbohydrates, but with a protein content of about 13 per cent, it is also the world’s leading source of vegetal protein in human food. However, it is just this protein content—the gluten—that is now causing controversy.

Gluten gives dough its elasticity, helping it rise and keep its shape while at the same time leaving the final product with a chewy texture. However, gluten can trigger adverse inflammatory reactions—a broad spectrum of gluten-related disorders, including celiac disease—in 1 or 2 per cent of the population. Also, between 6 and 10 per cent of people suffer from non-celiac gluten sensitivity. ‘Wheat Belly’ symptoms can include bloating, headaches, tiredness, and skin problems.

In his bestselling book Wheat Belly published in 2011, the American cardiologist William Davis claimed that modern wheat is addictive; he recommended that you exclude it entirely from your diet.  In promoting his book, he wrote:

‘The wheat of today is nothing like the wheat of 1960, 1950—that is, the wheat that our moms or grandmothers had—so it has been changed. This new crop has implications for human health that have never been anticipated. So, this is appropriate for nobody, no human, nobody in this audience, should be eating this modern creation of genetics research.’

He added: ‘I’d like to make the case that foods made with wheat make you fat…. I’d go as far as saying that overly enthusiastic wheat consumption is the main cause of the obesity and diabetes crisis in the United States.’

His views have been vigorously contested both by scientists and by the wheat industry. As an ex-sugar trader, I am personally delighted that he is blaming wheat rather than sugar for the obesity epidemic of the past forty years. I am, however, unqualified to give an opinion on the matter.

Cornucopia

Farming looks mighty easy when your plough is a pencil and you’re a thousand miles from the cornfield.  – Dwight Eisenhower

Corn is an awkward crop. Because of its shallow roots, it is susceptible to droughts, intolerant of nutrient-deficient soils, and prone to being uprooted by high winds. Corn reproduces sexually each year, randomly selecting half the genes from a given plant to propagate to the next generation. Corn breeding in prehistory led to larger plants and larger ears. Modern breeding began in the 19th century and, in the past 75 years, both conventional cross-breeding and genetic modification have succeeded in making corn less awkward, increasing output and reducing the impact of droughts and pests.

Many of the corn varieties grown in the US and Canada today are hybrids; over 90 per cent are the result of genetic modification. Grown commercially since 1997, GM corn now accounts for about one-third of the corn grown in the world, most of which has been genetically modified to tolerate glyphosate, or to provide protection against natural pests. Glyphosate, sold as Roundup, is a relatively inexpensive herbicide that kills all plants except those with genetic tolerance, which pretty much means all of them.

Monsanto released glyphosate-resistant soybeans under the name Roundup Ready Soybeans in 1996 and within ten years 80 per cent of all soybeans grown in the US were Roundup Ready.

Roundup Ready corn received FDA approval in 1997 and it was commercially released in 1998. It used much the same technology as in soybeans but also had built-in insect protection in the form of a Bt protein, a naturally occurring bacterium that lives in the soil and is toxic to insects.

Scientists also modified corn genes to make the crop more drought tolerance. The USDA approved drought-tolerant GM corn in 2011 and it was first commercialized in 2013.

Over the past twenty years, GM technology has revolutionised farming and transformed the seed and agricultural input business. Previously, much of a farm’s cost of production was in purchasing chemicals, fertilizer, herbicides and pesticides. Chemical companies made their money selling these inputs. Now the cost is in the development of the seeds. The result has been a merging of chemical and seed businesses with large chemical companies buying up the seed businesses.

Although GM technology has revolutionised the industry, its effect on yields is sometimes overstated.  By one estimate, about 50 per cent of yield increases since the 1920s have been the result of breeding, including genetic modification, while the other 50 per cent has come from improved farming practices. Better farming techniques have been just as important as genetics.

The USDA first began to publish corn yield estimates in 1866. Yields of open-pollinated corn varieties in the US remained fairly stagnant, averaging about 1.6 tonnes per hectare, for 70 years until about 1936. There was no significant change in productivity during that entire time period, even though farmers’ seed-saving practices represented a form of plant breeding.

Agricultural yields began to lift off with the adoption of hybrid corn in the late 1930s, but the most significant improvement in the annual rate of yield gain began in the mid-1950s in response to continued improvement in crop genetics, increasing adoption of nitrogen fertilizer and chemical pesticides, as well as agricultural mechanization. Since 1955, corn grain yields in the U.S. have increased at a fairly constant 1.9 bushels per acre per year, sustained primarily by continued improvements in genetics and crop production technologies.

The increase in global corn production in the last forty years has been more than impressive. In 1979, farmers in the US harvested 201 million tonnes of corn; in 2019 they harvested 366 million tonnes. In that same forty-year period, world corn production has increased from 425 million tonnes to 1.122 billion tonnes. Total world trade has increased by 100 million tonnes, from 70 to 170 million tonnes. However, in the same period, corn acreage has increased only 13 per cent, from 29 to 33 million hectares.

In his book More from Less: The Surprising Story of How We Learned to Prosper Using Fewer Resources―and What Happens Next the bestselling author Andrew McAfee writes:

‘Farms of less than one hundred acres grow 15 per cent less corn per acre than farms with more than a thousand acres. And bigger farms get better faster. Between 1982 and 2012 farms under one hundred acres grew their total factor productivity by 15 per cent, whereas farms over a thousand acres grew theirs by 51 per cent.’

And as for the environmental costs of large-scale farming, Andrew McAfee writes:

A comprehensive review published in Nature Sustainability in 2018 concluded: “The data does not suggest that environmental costs are generally larger for high yield farming systems. If anything, positive associations – in which high yield, land efficient systems also have lower costs in other dimensions – appear more common.”

In other words – and contrary to popular belief –  large farms are generally more environmentally-friendly than small farms.

But I am getting ahead of myself here. More on this in later posts.

More on the economics of cocoa

Readers have posed some interesting questions following my blog last week on cocoa.

One asked me to explain why I said a minimum sales price becomes a ceiling on the market. The answer is that if the price can’t go up, it will go down. If traders and manufacturers know that they can buy at a specific price, they have little risk in being short below that price. If the price rises, they can cover their shorts at a predictable loss. Minimum prices skew the risk/reward ratio and encourage people to sell short.

On a broader level, one commented that, because Ghana and Ivory Coast account for 60 per cent of world cocoa, they have the market power to set cocoa prices. He suggested that cocoa producers should get together to form COPEC, cocoa’s equivalent of OPEC.

Unfortunately, cocoa is not the same as oil. Oil producers can reduce supply by turning off a tap; they can leave it in the ground. It doesn’t deteriorate. Cocoa producers can’t turn off a tree. The trees keep producing, cocoa builds up at the ports, rots in the warehouses, and loses some, or all, of its value. In the meantime, farmers are left unpaid – with all the dire consequences that entail.

Cocoa is a front-loading crop: grinders and chocolate manufacturers tend to hold large stocks that they can run down if producers hold off new sales. Cocoa buyers are more affluent and better financed than producers – and they probably have better infrastructure.

One reader argued that the market is almost as concentrated on the buy-side as it is on the sales side. I very much doubt that cocoa buyers work together in the same way that cocoa producers do. Still, I would guess the balance weighs in the buyer’s favour in terms of market power.

A couple of readers pointed out that as growers only receive around 5 per cent of a chocolate bar’s cost, increasing the cocoa cost by $400 per tonne would only increase the bar’s price by one or two per cent. They have a point. Besides, Cargill recently conducted a survey that showed consumers would be willing to pay more if they thought that the farmer would benefit. ‘Surely,’ asked one reader, ‘consumers would pay 2 per cent more for their chocolate if they thought that it helped the farmers?’

The answer is that it would, but, increasing the price that farmers receive would encourage them to produce more, adding further pressure on prices.

Expressing this problem differently, another reader said that producing and consuming countries should cooperate in setting a fair price for cocoa.

In the past, the United Nations has done that by setting up commodity organisations to ‘manage’ the markets; cocoa, coffee, or sugar were three such examples. These commodity organisations tried to use stock management to bring supply and demand into balance at a price that gave a decent return to growers and a reasonable price for consumers.

When world prices fell, the various commodity bodies set to work by either purchasing (in the case of cocoa) physical cocoa to hold off the market or asking (in the case of coffee and sugar) producers to build stocks and limit exports. When prices rose again, they released these stocks.

These noble efforts, sadly, failed. When prices fell, coffee producers continued to export; they desperately needed the money to feed themselves. In the case of cocoa, the ICCO ran out of funding. In the case of sugar, producers failed to build the stocks they were supposed to. (Brazil famously said that their inventories were in the cane in the fields.)

As a consequence, when prices rose, either the stocks weren’t there or were insufficient to stem the prices’ rise.

As we saw earlier, market participants will tend to sell short ahead of a stock release price level; if stocks aren’t there, then the price explodes as shorts run for cover. It means that not only do international price agreements not work, they also actually increase market volatility. They are like communism: a great idea in theory, but a disaster in practice.

It is true even if the producers are in rich, developed countries.

The EU used to fix minimum prices for many agricultural products, maintaining them through a mix of quotas, stock management and subsidised exports. Over the years, production costs dropped as farmers became more efficient. Still, the EU continued increasing their minimum prices in line with general inflation. In the end, sugar prices were so profitable that French farmers used to call sugar beet quotas’ white gold’. Butter mountains and wine lakes built up. So did subsidise exports – to the detriment of farmers in importing countries.

The EU has gradually wound down their market management schemes (sugar and milk were the last to go), along with, thank goodness, subsidised exports. The EU has replaced them with direct income support. Agriculture is still the largest item in the EU’s budget at 38 per cent, but down from 73 per cent in 1985.

Finally, one, rather astute, reader argued that the Ivory Coast should have thanked Hershey for taking delivery of the December futures market. By doing so, Hershey pushed the world cocoa price higher, taking some of the old crop cocoa (that had been weighing on prices) off the market. He may have a point.

Instead of manipulating the world price, what should Ghana and Ivory Coast do to help their impoverished growers? I posed that question this week to the head of one of the leading NGOs in the sector. I will publish his replies shortly.

Cocoa economics

Cocoa farmers in Ivory Coast went on strike last week in protest against the low prices they are currently being offered for their crop. They have also threatened to block port warehouses where more than 100,000 tonnes of cocoa have backed up due to a lack of demand. A farmers’ representative told Bloomberg that farmers are only being paid 800 CFA francs per kilo against the state-guaranteed minimum price of 1,000 CFA francs, roughly $1.85/kg.

Covid19 is partly to blame for the lack of demand. The FT (subscription required) reports that the virus has disrupted ‘sales of chocolate at airports, hotels, restaurants and speciality boutiques’. As a result, world cocoa demand fell 2-3 per cent last year, prompting processors and chocolate manufacturers to delay shipments on quantities that they have already bought, and hold off on new purchases. This drop in demand has hit the Ivory Coast particularly hard. Together with Ghana, the country produces 60 per cent of the world’s cocoa.

Ghana and Ivory Coast work together more closely than in the past, setting similar ex-farm prices and reducing smuggling across their borders. In 2019, they looked at ways to increase farmers’ incomes and discussed setting a minimum export price. They eventually rejected the idea and instead introduced a ‘Living Income Differential’ (LID), a $400 per tonne premium that buyers had to pay over the world price, starting with the 2020/21 season.

The $400 per tonne LID was not just a premium over the futures; it was also in addition to the country differentials.

Country differentials (premia and discounts relative to the futures) fluctuate widely; they often depend on the cocoa that the market expects to be delivered against the futures. Processors prefer new crop cocoa to old crop, and the futures can be depressed, for example, if old crop is expected to be delivered.  For the 19/20 season, exporters probably paid an average premium of about £75 for Ivory Coast and £125 for Ghana, as these purchases were made starting in September/October 2018.

The larger cocoa processors – particularly the ones with factories in Ivory Coast – have paid LID on their 2020/21 purchases, but they have had difficulty passing it on to their buyers. Unlike Fairtrade or the Rainforest Alliance, LID doesn’t come with a certificate that can be handed on to the chocolate manufacturers. Without a certificate, manufacturers can’t put a label on their retail packaging, nor ask their customers to pay more.

Rather than pay LID, Hershey was reported last month to have taken delivery from the December futures contract: a mixture of the old crop cocoa from West African, Ecuador and Sulawesi.

In response, Ivory Coast and Ghana launched an unprecedented media campaign against Hershey. They also threatened to suspend the company’s sustainability programmes in the two countries. It is not clear what arrangement Hershey made with Ivory Coast and Ghana, but it has been reported that Hershey has agreed to pay the Living Income Differential. Still, as Hershey does not buy directly from the Ivory Coast, it is unclear how that works.

It is also unclear how Ghana and the Ivory Coast expected LID to work in the first place.

By asking their customers to pay $400 per tonne more for Ghanaian or Ivory Coast than for other cocoa, chocolate manufacturers had a strong incentive to buy alternative origins. Ghana and Ivory Coast have tried to stop this by putting media – and local – pressure on the big chocolate companies. Still, the big companies account for less than half of the world’s chocolate production and an even smaller percentage of beans.

The cocoa market is looking at a surplus this year of up to 300,000 tonnes. Because of LID, this surplus is now primarily made up of cocoa from Ivory Coast and Ghana. At this time of the year, the Ivory Coast would have customarily sold all of this crop, most of their mid-crop and a significant chunk of the following main crop. Instead, they still have an estimated 500,000 tonnes to sell from the 2020/21 season and a similar quantity from the 2021/22 crop. They have not sold anything yet for 2022/23.

Cocoa is what is known as a ‘front-loading’ commodity. The harvest runs from October through March, with shipments concentrated during this period; processors then store the cocoa and use it throughout the year. With storage costs at around £12 per month, it is not surprising that buyers have been delaying purchases, aggravating the build-up at the origin. Time is on the side of the buyers; they can afford to wait.

The inevitable has happened: both Ghana and Ivory Coast have reduced prices to tempt buyers. Country differentials have fallen to a discount of £150 – 200 per tonne. Unfortunately, they have little success even at those prices; buyers have either already bought elsewhere or are waiting for prices to fall even further.

But isn’t this just bad luck on the part of Ghana and Ivory Coast? Wouldn’t LID have worked if the balance sheet had been in deficit rather than surplus? Unfortunately, the answer to both questions is ‘no’.

If there had been a deficit, the outright cocoa price would indeed have risen. Unfortunately, neither Ghana nor Ivory Coast would have been able to sell if they had continued to ask for a premium of $400 per tonne over the market. The world price could have gone to the moon, but they would still have asked for $400 per tonne more. To move their crop, the country differentials would have been reduced – probably to levels similar to where they are today. As with all farmers, it is the outright price that matters, not the differentials.

So, what is to be done? With hindsight, the obvious answer would have been to go with the two countries’ original idea and set a minimum price, not a differential. Even then, with a market in surplus, the world price would have fallen below the minimum price; Ivory Coast and Ghana still wouldn’t have sold. The minimum price would have become a maximum price with the market only buying it when it was needed.

It is sad to say, but cocoa economics are the same as everyone’s else’s economics: the only cure for low prices is low prices.

Rising food prices

 

With grain and soybean prices reaching levels not seen since 2014, I expect that the media will soon be writing about global food shortages. There will be accompanying calls for governments to intervene to cap domestic food prices. There will also be calls to control the markets and ‘punish’ speculators.

Last week already, a group of scientists warned that the world was ‘facing a ghastly future of mass extinction’ and that the continued growth in world population is driving soil degradation and biodiversity loss. The scientists included Prof Paul Ehrlich from Stanford University, author of The Population Bomb, published in 1968. In that book, Prof Ehrlich warned that the population explosion would lead to hundreds of millions of people starving to death (in the 1970s).

In an interview in 2018, Prof Ehrlich commented that although ‘details and timings of his predictions were wrong, his book was correct overall’. He said: ‘Population growth, along with over-consumption per capita, is driving civilisation over the edge: billions of people are now hungry, or micronutrient malnourished, and climate disruption is killing people.’ He still believes that the world will run out of food and that millions will starve.

He is not the first to think this. In 1798, the English clergyman Reverend Robert Malthus wrote his famous Essay on the Principle of Population in which he predicted that the world’s population would be checked by famine. Malthus argued that the world’s food supply grew arithmetically, while the world’s population grew geometrically.  He wrote: ‘The power of population is indefinitely greater than the power in the earth to produce subsistence for man.’

Malthus believed that God had made it that way to teach humanity ‘virtuous’ behaviour. He believed that humankind should lead a subsistence life, and he predicted a future of ‘misery and vice’.

When Malthus wrote his essay, there were about one billion of us humans on our planet. Since then, the world population has increased more than eight-fold. Agricultural production has more than kept pace, so much so that the world is now struggling with obesity, not starvation.

Population growth is not currently driving grain prices higher. Rather, it is a mixture of bad weather, poor crops, well-intentioned, but inappropriate, government intervention, and a rush of imports into China as the country rebuilds both its stocks and its pig herd. To that heady mix, you have to add financial factors: inflation fears and a weakening dollar.

Nor will population growth drive grain prices higher in the future. The growth in agricultural production – largely through yield increases – continues to outpace population growth. This correlation contains an important causality: the growth in agricultural yields has permitted the growth in world population. There is no reason why this should suddenly change.

But what about temporary shortages – how can we deal with them?

The growth in yields over the past seventy years has led to such a huge increase in agricultural production that roughly 40 per cent of US corn production – and 50 per cent of European rapeseed production – is now used to fuel cars rather than humans.

Could crops currently used for fuel be diverted back to food in times of high food prices? This already happens on a huge scale with sugar in Brazil. When sugar shortages develop and sugar prices rise, millers produce more sugar and less ethanol.  Western countries have even less flexibility in corn or rapeseed, largely because of government-set ethanol and biodiesel mandates.

Not only has agricultural production increased enough to feed the population and fuel our cars, but it has also allowed us to eat more meat. A staggering 98 per cent of the world’s soybean production – and 36 per cent of US corn production – is fed to animals to produce meat and dairy. Animals are rather inefficient in converting grain and beans into meat. It takes 25 kg of feed for a cow to produce one kilo of edible meat and it takes 15 kg of feed for a sheep to produce one kg of lamb. (The figures for pork and chicken are 6.4 kg and 3.3 kg respectively.)

Could some of that animal feed be diverted back to direct human consumption? In theory, yes. In practice, it would take a large increase in meat prices to reduce meat consumption, and then only with a relatively long time lag. It wouldn’t happen quick enough to solve a temporary grain shortage.

Increased agricultural production and low food prices have also encouraged waste. It is often said that 30 per cent of food is wasted. Waste occurs in developing countries through unharvested crops, poor storage and a lack of refrigeration. Food waste in rich countries occurs in supermarkets, restaurants, and the kitchen. I am not sure that 30 per cent figure is correct, but even if it is, it is doubtful that much can be done about it in the short to medium term.

All this means that the short-term solution to high grain prices lies on the supply side. High prices will encourage farmers to plant more for the next season while at the same time encourage the whole supply chain – from the farm silo to the supermarket – to draw down stocks.

Modern-day markets have become so efficient that prices now rise in advance of shortages. Futures markets trade the future; they solve the problem before it occurs. Anything that interferes with – or delays – these price signals (such as government intervention) will in the end only makes matters worse.

This is part of a series of ‘long reads’ called ‘Why food doesn’t have to cost the earth’.

How we got here

Our planet is roughly 4.5 billion years old. Our human ancestors appeared on Earth around 66 million years ago. Still, as we know ourselves today, humans have only existed for the last 2 million years, the vast majority of that time as hunter-gatherers.

Humans may have begun to grow crops on the Sea of Galilee’s shores about 23,000 years ago. However, agriculture proper did not start to develop until 12,000 years ago when hunter-gatherers in the ‘Fertile Crescent’ began growing wild varieties of crops like peas, lentils and barley. They also herded wild animals like goats and oxen in the region.

Historians disagree as to why our ancestors made the structural shift from hunting and gathering to farming. Some argue that a changing climate left them no alternative but to seek alternative sources of foods. Some suggest the transition was more a result of our perpetual drive to improve our condition. Others even suggest that a love of beer drove them to give up their nomadic lifestyles. Archaeologists estimate that 40 per cent of early wheat production went to make beer—the oldest barley beer dates to 3400 BC.

In broad-brush terms, historians divide agricultural progress into three stages. The First Agricultural Revolution defines the move from hunting-gathering to farming that occurred 7-10,000 years ago. The Second Agricultural Revolution refers to the mineral fertilisers and the industrialisation of farming and farm processing in the 19th century. We are still living through the Third Agricultural Revolution, or the ‘Green Revolution’, that began in the middle of the 20th century. It involved improved crop yields through breeding and the introduction of agricultural inputs such as fertiliser and pesticides.

Farming changed little during the first 10,000 years of human history. Farmers regularly left fields fallow, and animal manure was the sole fertiliser. In the early 1800s, scientists began to understand that inorganic minerals such as nitrogen, potassium, lime, and phosphoric acid could replenish depleted soils.

The search for fertiliser led merchants and scientists to the dry seabird islands off the South American and South African coasts, where immense deposits of bird droppings, rich in nitrogen and phosphorus, had accumulated over centuries. Guano mining became a profitable business. Between 1840 and 1880, guano nitrogen made a vast difference to European agriculture, but the best deposits were soon exhausted. However, miners found rich mineral nitrate deposits in Chile, and nitrates gradually replaced guano in the late 19th century.

In The Omnivore’s Dilemma, Michael Pollan writes that the great turning point in the modern history of agriculture can be dated to the day in 1947 when a munitions plant in Alabama switched away from making explosives to make chemical fertiliser instead. He explains that at the end of World War II, the US government found itself with a surplus of ammonium nitrate, the principal ingredient in making explosives. Ammonium nitrate is an excellent source of nitrogen for plants. Chemical fertilisers and pesticides were the product of the US government’s effort to convert its war machine to peacetime purposes.

Even though the Earth’s atmosphere is about 80 per cent nitrogen, nitrogen atoms have to be split and joined to hydrogen atoms (‘fixed’) to make fertiliser or bombs. A German Jewish chemist named Fritz Haber worked out how to do that in 1909. Before he made that discovery, all the usable nitrogen on Earth had to be fixed by soil bacteria or electrical lightning, which breaks down nitrogen bonds in the atmosphere.

In his book, Enriching the Earth: Fritz Haber, Carl Bosch and the Transformation of World Food Production, Vaclav Smil explains that ‘there is no way to grow crops and human bodies without nitrogen’. Without Haber’s invention, the small amount of nitrogen that bacteria and lightning alone could release would have limited the number of people that agriculture could support.

In his book, Mr Smil argues that the Haber-Bosch process for fixing nitrogen (Bosch commercialised Haber’s idea) was the most important invention of the 20th century. He estimates that 40 per cent of the people on Earth today would not be alive without Haber’s invention. Without synthetic fertiliser, billions of people would never have been born.

Fritz Haber won the Nobel Prize in 1918 for ‘improving the standards of agriculture and the well-being of mankind’, but, since then, he has largely been airbrushed out of history. During the First World War, he helped the German war effort by making bombs from synthetic nitrate. Worse, he also developed poison gases, including Zyklon B, used in the Nazi concentration camps.

The Haber-Bosch process works by combining nitrogen and hydrogen gases under immense heat and pressure, supplied by electricity. The hydrogen is provided by oil, coal or, most commonly today, natural gas. As such, Michael Pollan argues that once humanity had acquired the power to fix nitrogen, the basis of soil fertility shifted from a total reliance on the energy of the sun to a new dependence on fossil fuel.

Farming, which had historically always been a process of converting sunlight into food, has become a process of converting fossil fuels into food. More than half of the world’s supply of usable nitrogen is now human-made—and farmers use more than half of all the synthetic nitrogen made today to grow just one crop: corn.

Some excess nitrogen evaporates into the air, acidifying the rain and contributing to global warming. Some seep down to the water table and the rivers. Mr Pollan writes:

‘The ultimate fate of the nitrates spread in Iowa or Indiana is to flow down the Mississippi into the Gulf of Mexico, where their deadly fertility poisons the marine ecosystem. The nitrogen tide stimulates the wild growth of algae, and the algae smother the fish, creating a ‘hypoxic’, or dead, zone as big as New Jersey–and still growing. By fertilising the world, we alter the planet’s composition of species and shrink its biodiversity.’

He is right, of course. The world would be a very different place if it were not for the advances in agriculture and agricultural technology that occurred over the past century. Admittedly it would probably be less polluted, and we might eat better, but two out of five of us probably wouldn’t be here. And of the remaining three, at least one would go to bed hungry every night.

Some might argue that the world would be a better place if there were 40 per cent fewer of us on the planet. But, personally, I am happy to be here.

Traders and merchants

Coffee traders and merchants move coffee from areas where it grows well (and cheaply) to places where it grows less well, or not at all. They transport coffee from surplus areas to deficit areas.  If coffee is worth more money in the US than in Brazil – and if that difference is more than the cost of shipping it (plus a little profit margin to make it worthwhile), then the trader or merchant will make it happen.

Coffee traders do not only move coffee from surplus to deficit areas. They also store and process it. They hold coffee at times when it is not needed (after the harvest) until a time it is needed (throughout the year). Coffee millers process coffee from a form in which it is not wanted into a condition in which it is wanted, transforming cherries into green beans. Roasters transform the green beans into roasted or soluble coffee.

Millers and roasters are, by definition, traders. A miller buys cherries and sells green beans, while a roaster buys green beans and sells roasted beans. Just as a trader may depend for his livelihood on his skill in buying coffee in one country and selling it in another, a roaster depends on his skill in buying coffee in one form and selling it in another. Millers and roasters are traders, and they need trading skills to perform their tasks correctly.

When you think about that a little, it becomes clear that what a trader is most interested in is not the outright price of coffee but the difference in the prices of that coffee in its different geographies, times and forms.  It is the price differential that matters, not the outright price. Traders like to limit their exposure to the outright, or flat price, of a commodity. They usually hedge their outright price risk, preferring to make their money on the differentials – the difference between the cost of the futures and the price of their particular coffee.

All traders – and that includes roasters – will try to reduce their risk of future price movements by hedging what they buy, taking an offsetting position for the same quantity in the futures market. Having purchased the physicals, a trader will sell futures as a hedge. When he sells the coffee, the trader will buy back their futures hedge; they no longer need to be protected against a move in the outright price of coffee because they don’t own it anymore.

Everyone involved in the coffee supply chain is taking and managing price risk. The farmer is perhaps taking the most significant risk by growing coffee in the first place. He may try to offset some of that risk by selling in advance – selling something that he doesn’t (yet) have.

The trader is taking a risk on the quantity that he buys but offsets that risk by hedging in the futures market. The roaster is also taking a risk; he has invested in his roasting machinery and has the risk that coffee prices will be too high to allow him to make a profit when he sells his roasted beans.

When I began my trading career with Cargill in the late 1970s, my first business card gave my title as ‘Commodity Merchandiser’.  But what is the difference between a trader and a merchandiser? Traders take positions on the markets, betting whether prices – or the differentials between prices – will rise or fall. Merchandisers move commodities along the supply chain, taking a tiny margin at each stage of its journey.

Traditional commodity merchandising has become more challenging and less profitable over time. It has become tough to make a margin just moving coffee along the supply chain.

One of the significant difficulties that merchandisers now face is that information is widely and freely available. It also travels incredibly fast. Technological change has reduced the potential for traders to arbitrage prices between geographical regions.

The other significant change is that governments and government agencies have pretty much left the coffee business. In the past, governments were often responsible for selling their country’s production, and this led to opportunities for corruption. Low-paid government officials were easy targets for unscrupulous traders; selling tenders were often rigged in favour of the traders that gave the biggest bribes. The markets have now been privatised, and this no longer happens.

In a world of instant information, it is no longer possible for merchants to take advantage of price differentials in various countries; instead, they now have to anticipate them. It is the point where a merchant becomes a trader. A trader predicts where shortages and surpluses will occur, and he takes a position in the market in anticipation of future price moves. As a result, analysis has become the lifeblood of trading.

It is not unusual for a trading company to employ more analysts than traders. Nor is it uncommon for traders to spend most of their time not on trading, but analysis. It is impossible to succeed in the commodity markets without an experienced group of traders and analysts to interpret and understand the mass of information that needs to be absorbed.

But analysis is not the only thing that you need to succeed in the physical commodity markets: you also need clients. Traders, therefore, have to keep in regular contact with their client networks, and they have to move physical coffee along the supply chain. There is now such an overlap between trading and merchandising that they are pretty much the same thing.

Merchandising coffee allows you to see the trade flows, helps with your analysis, and enables you to anticipate trading opportunities in the coffee market. But the margins on straight merchandising are now so thin – and sometimes even negative — that it is pretty much impossible for a pure coffee merchandiser to survive. The profits from trading subsidise the lack of profits, or the losses, on merchandising. In that sense, merchandising enables trading, and trading facilitates merchandising. They are mutually dependent.

The History of Coffee

No matter what historians claimed, BC really stood for ‘Before Coffee’.― Cherise Sinclair

The first reference to coffee as we know it today was in the early 15th century when the Arab mystic al-Dhabhani saw Ethiopians drinking ‘qahwa’, now the Arab word for coffee. The Ethiopians, however, call coffee ‘buna’, which also means bean.

As coffee gained popularity throughout the Arab world, it began to be used less as a religious drink and more as a social stimulant. In 1511, Khair-Beg, the governor of Mecca, ruled that coffee was like wine and hence banned by the Koran. He ordered the city’s coffee houses to be closed, only to have the ban overturned by his boss, the Sultan of Cairo.

Despite its growing popularity, coffee production was slow to pick up; it was only after the Ottomans occupied Yemen in 1536 that they began to extensively cultivate the crop in the country. The Ottomans exported the coffee from the port of Mocha, and it became known as ‘mocha’.

When the first English sailor reached the port in 1606, he wrote that there were over thirty-five merchant ships, some from as far away as India, waiting to load the precious green beans.

Some of the coffee was shipped to Alexandria in Egypt and then on to Venice. Still, mostly it stayed within the Ottoman empire, reaching Damascus and Istanbul by the middle of the century. By then, coffee was no longer considered just a religious drink, but also a social one. By the end of the 16th century, there were over 600 coffee shops operating in Istanbul.

The way of brewing coffee changed as it travelled. Arabic coffee (qahwa) is a light-coloured liquid made by lightly toasting the beans, crushing them with various spices such as cardamom, and then boiling them in water. Turkish coffee (kahve) is made with more darkly roasted beans and brought to the boil at least twice but without spices.

For a time, the Ottomans successfully prevented coffee cultivation from spreading outside the area of Mocha; they refused to let berries leave the country unless they were first boiled in water to prevent their germination. However, exports had grown to such a level that it was impossible to stop some un-boiled beans from getting through. As Muslim pilgrims returned to their homes, they took coffee beans with them.

One such pilgrim, Buba Budan, is credited in 1600 with smuggling out some beans by taping seven of them to his stomach. He took them back to India and planted the beans next to his hut at Chickmaglur in the mountains of Mysore. Buba Budan is now (rightly) revered as a saint, but it was not until 1840 that the English began the commercial cultivation of coffee in India; the plantations extend now from the extreme north of Mysore down to Tuticorin.

In 1614, Dutch traders brought a coffee plant from Mocha to Amsterdam, and by mid-century, they had taken plants to Ceylon (now Sri Lanka) and Dutch Malaba (now Cochin), where they started small plantations. From there, in 1696, the Dutch took cuttings from the plants to their colonial island of Java. A flood washed away the early seedlings, but the Dutch tried again three years later, this time successfully. In 1706, the first Java coffee had reached Amsterdam; some coffee plants were grown successfully in Amsterdam’s botanical gardens.

During the 17th century, ‘Mocha’ and ‘Java’ became synonyms for coffee; they are still so today.
