Odd Crop Prices Defy Economics

By DIANA B. HENRIQUES

Economists note there should not be two prices for one thing at the same place and time. Could a drugstore sell two identical tubes of toothpaste, and charge 50 cents more for one of them? Of course not.

But, in effect, exactly that has been happening, repeatedly and mysteriously, in trading that sets prices for corn, soybeans and wheat — three of America’s biggest crops and, lately, popular targets for investors pouring into the volatile commodities market. Economists who have been studying this phenomenon say they are at a loss to explain it.

Whatever the reason, the price for a bushel of grain set in the derivatives markets has been substantially higher than the simultaneous price in the cash market.

When that happens, no one can be exactly sure which is the accurate price in these crucial commodity markets, an uncertainty that can influence food prices and production decisions around the world.

These disparities also raise the question of whether American farmers, who rely almost exclusively on the cash market, are being shortchanged by cash prices that are lower than they should be.

“We do not have a clear understanding of what is driving these episodic instances,” said Prof. Scott H. Irwin, one of three agricultural economists at the University of Illinois at Urbana-Champaign who have done extensive research on these price distortions.

Professor Irwin and his colleagues, Prof. Philip T. Garcia and Prof. Darrel L. Good, first sounded the alarm about these price distortions in late 2006 in a study financed by the Chicago Board of Trade. Their findings drew little attention then, Professor Irwin said, but lately “people have begun to get very seriously interested in why this is happening — because it is a fundamental problem in markets that have generally worked well in the past.”

Market regulators say they have ruled out deliberate market manipulation. But they, too, are baffled. The Commodity Futures Trading Commission, which regulates the exchanges where these grain derivatives trade, has scheduled a forum on April 22 where market participants will discuss these anomalies and other pressure points arising in the agricultural markets.

The mechanics of the commodity markets are more complex than selling toothpaste, however. The anomalies are occurring between the price of a bushel of grain in the cash market and the price of that same bushel of grain, as determined by the expiration price of a futures contract traded in Chicago.

A futures contract is an agreement to deliver a specific amount of a commodity — 5,000 bushels of wheat, say — on a certain date in the future. Such contracts are important hedging tools for farmers, grain elevators, commodity processors and anyone with a stake in future grain prices. A futures contract that calls for delivery of wheat in July may trade for more or less for each bushel than today’s cash market price. But as each day goes by, its price should move a bit closer to that day’s cash price. And on expiration day, when the bushels of wheat covered by that futures contract are due for delivery, their price should very nearly match the price in the cash market, allowing for a little market friction or major delivery disruptions like Hurricane Katrina.

But on dozens of occasions since early 2006, the futures contracts for corn, wheat and soybeans have expired at a price that was much higher than that day’s cash price for those grains.

For example, soybean futures contracts expired in July at a price of $9.13 a bushel, which was 80 cents higher than the cash price that day, Professor Irwin said. In August, the futures expired at $8.62, or 68 cents above the cash price, and in September, the expiration price was $9.43, or 78 cents above the cash price.

Corn has been similarly eccentric. A corn futures contract expired last September at $3.36, which was a remarkable 55 cents above the cash price, but the contract that expired in March 2007 was roughly even with the cash price.

“As far as I know, nothing like this has ever happened in the corn market,” said Professor Irwin.

Wheat futures had been especially prone to this phenomenon, going back several years. Indeed, the 2007 study by Professor Irwin and his colleagues concluded that wheat price distortions reflected a “failure to accomplish one of the fundamental tasks of a futures market.”

And while the situation improved sharply for wheat futures in Chicago late last year, it deteriorated for futures traded in Kansas City. And it has gotten worse for corn and soybeans, Professor Irwin said. Many people have a theory about why this is happening, but none of them seem to cover all the available facts.

Mary Haffenberg, a spokeswoman for the CME Group, which owns the Chicago Board of Trade, where these contracts trade, said the anomalies might be a temporary result of “a lot of shocks to the system,” including sharp increases in worldwide food demand, uncertainty about supplies and surging commodity investments.

Veteran traders and many farmers blame the new arrivals in the commodities markets: hedge funds, pension funds and index funds. These investors and speculators, they complain, are distorting futures prices by pouring in so much money without regard to market fundamentals.

“The market sends a sell signal, but they don’t sell,” said Kendell W. Keith, president of the National Grain and Feed Association. “So the markets are not behaving the way they otherwise would — and the pricing formula for the industry is a lot fuzzier and a lot less efficient than we’ve ever seen.”

Representatives of the new financial speculators dispute that. Their money has vastly increased the liquidity in the futures markets, they say, and better liquidity improves markets, making them less volatile for everyone.

And, as Professor Irwin noted, if new money pouring into the market has been causing these distortions, they probably would be occurring more consistently than they are.

Some experienced commodity analysts think the flaw may be in the design of the contracts, said Richard J. Feltes, senior vice president and director of commodity research for MF Global, the world’s largest commodity futures brokerage firm. If futures were settled based on a cash index, it would eliminate these odd disparities, Mr. Feltes said.

Ms. Haffenberg at the CME Group said cash settlement had “not been ruled out,” but it raised the question of finding the appropriate cash index. Other modest contract changes are awaiting approval of the futures trading commission, she said.

“We are continuing to have industry meetings to discuss what we need to do,” she said. “But we want to be careful, before we undertake any changes, that above all, we don’t do any harm.”

Moreover, defenders of the exchange’s current contract design note that these widely used agreements have gone largely unchanged for some time — and yet, have only begun to display this odd and inconsistent behavior in the last few years.

Some economists are exploring whether some unperceived bottlenecks in the delivery system explain what is going on. But traders say that such bottlenecks would eventually become known in the market and prices would adjust. Professor Irwin, whose research is continuing, said there might not be a single explanation for the price distortions.

Markets may simply be responding to the uneven impact of new financial technology, which allows more money to flow in and out, and to investors’ growing but fluctuating appetite for hard assets.

“Those factors may be combining to create this highly volatile environment for discovering prices,” he said. “But for now, that is pure conjecture on my part.”

What is not happening in these markets is equally mysterious. Normally, price disparities like these are quickly exploited by arbitrage traders who buy goods in the cheap market and sell them in the expensive one. Their buying and selling quickly brings the prices back into balance — but that is not happening here.

“These are highly competitive markets with very experienced traders,” he said. “Yet they are leaving these profits alone? It just doesn’t make sense.”

WSJ : the "latest" from those idiots at Calpers -- Calpers Sells Stock Amid Rout to Raise Cash for Obligations ..........

Calpers Sells Stock Amid Rout to Raise Cash for Obligations

By CRAIG KARMIN and JOANN S. LUBLIN

The nation's largest public pension fund, known as Calpers, is unloading stocks in a falling market to make sure it has enough cash to meet its obligations.

The pressures come as the California Public Employees' Retirement System has had to raise cash to fulfill commitments to private-equity firms and real-estate partners. The giant fund's predicament is another sign of how the market selloff is tightening the screws on pension funds nationwide. Many other pension funds have similar partnerships and could also confront liquidity strains.

Members of the board investment committee at Calpers held a closed-door session on Monday and discussed ways to raise more cash, according to people familiar with the matter. The issue was brought to the attention of the committee after members of the investment staff expressed concern, a person with knowledge of the matter said.

Typically, Calpers keeps less than 2% of its assets in cash, but the recent demands have forced it to raise that level.

"Calpers receives more than enough cash from employers and members to cover its monthly benefit obligations" to retirees and other beneficiaries, a Calpers spokeswoman said Friday.

Under normal conditions, pension funds count on some private-equity partners to distribute investment gains, while pensions owe some partners more capital. During the recent market selloff, however, distributions have dried up while capital calls continue. That's created a mismatch and a cash strain.

Since the credit markets have tightened up and real estate and alternative investments aren't very liquid, Calpers has been compelled to sell off stocks to raise large sums quickly. Those sales are turning paper losses into realized losses.

Calpers said it had $188.8 billion under management as of Wednesday, down 21% from the end of June. The fund, which said it had about 63% of its assets in global stocks at the end of August, has been punished severely by the stock-market selloff.

Critics say that some of Calpers's troubles are of its own making. The pension fund is the main investor in a partnership that is expected to lose much of its nearly $1 billion investment in LandSource, a venture that owns thousands of acres of undeveloped residential land north of downtown Los Angeles and that filed for bankruptcy protection in June.

The pension fund also has been without two of its top leaders, the chief executive officer and chief investment officer, since they resigned at midyear. The fund has been operating with interim people in those key positions.

Calpers initially tried to fill the CIO spot first, but without any luck. A former fund official said that candidates were reluctant to take the job while the permanent CEO position remained vacant. Calpers is now focusing on landing a CEO first, recently hired a search firm and hopes to have its new leader in place by December, people familiar with the matter say. The fund intends to have a CIO by no later than February.

Anne Stausboll, a politically well-connected attorney and the former California chief deputy treasurer, is serving as interim CIO. She appears to be the only top Calpers official vying for the CEO job, according to people familiar with the situation. She doesn't have the investment experience that is common for a CIO of a large fund, which critics say puts Calpers at a further disadvantage during this particularly severe market crisis.

"Calpers's investment office is being capably managed by our interim CIO and her team of seasoned investment professionals," the spokeswoman said.

Calpers counts 1.6 million former and current public employees as members whose benefits are contractually guaranteed. If the fund suffers large investment losses, it has little choice but to hit up employers -- such as cities and counties -- to increase their contributions. Calpers recently indicated plans to raise the contribution level starting in 2010 and 2011, unless the recent investment losses can be reversed. The fund estimates that employers would have to pay an additional 2% to 4% of their payroll to Calpers if the June fiscal year ends with returns of negative 20%, which the fund recently hit.

WSJ piece on collapse in metals prices / mining business ....................................

NOVEMBER 17, 2008

Giant Mines Scramble to Cut Output

By PATRICK BARTA, ROBERT GUY MATTHEWS and ANDREW BATSON

Mining companies -- which couldn't dig minerals out of the earth fast enough just a few months ago -- now are struggling to climb out of a very deep hole.

On Friday, the world's biggest miner, BHP Billiton, said major Chinese customers are trying to delay purchases of iron ore as China's building boom slows sharply. The scale of the December delays could cut BHP's iron-ore deliveries by at least 5% for the full year.

The mining giants that feed the world's appetite for iron, copper and other industry staples earned piles of money as commodities prices soared the past few years. But those days are over for now.

Metals prices fell 35% in just four weeks last month -- the steepest decline ever recorded, according to Barclays Capital. Prices for palladium, a key ingredient in automobile catalytic converters, are down 70% since midyear as car buyers make themselves scarce. Half or more of the world's aluminum production is now unprofitable.

Mining companies, a significant barometer of global economic health, are shuttering operations and firing thousands of workers across South Africa, Australia, Canada and Russia.

Rio Tinto cut 10% of its iron-ore production last week, matching a similar move by the world's largest iron-ore producer, Brazil-based Companhia Vale do Rio Doce. On Thursday, Xstrata PLC announced plans to close two nickel mines in Northern Ontario. Alcoa Inc. has so far cut about 15% of its annual capacity.

Big steelmakers world-wide have been cutting production as much as 35%. U.S. Steel Corp., the largest steelmaker in the U.S, last week said it was laying off 2% of its work force due the the slowing economy.

Nearly every mineral is affected. Molybendum, which gives steel its strength, fell 60% to $12 a pound in the past year. Copper -- recently so expensive that burglars would break into houses not to steal jewelry, but to steal the plumbing -- is off more than 50% since April. Tin smelters across Indonesia, where nearly 25% of the world's tin is made, are halting production.

Mining ranked among the fastest-growing sectors of the world economy in recent years. That money flowed to the four corners of the globe. China's voracious appetite for commodities helped spur waves of investment in poor but resource-rich Africa, a rare economic bright spot there.

That's changing now, as Chinese demand slows at the same time that consumers world-wide start penny-pinching. In the past few days, the world's largest producer of steel ingredient ferrochrome, Merafe Resources Lindiwe Montshiwagae, said it would shut down six of its South African furnaces. In Kenya, a $25 million titanium project was also put on hold.

The question is whether these cutbacks, while sizeable, will be enough to stabilize prices and the industry. Markets got a brief boost on Monday when China announced a nearly $600 billion spending spree to perk up its economy by building new roads and railways, among other things. By Tuesday, however, prices for many commodities resumed their decline as the reality set in that even China's plan might not be enough to prop up demand in the short term.

The mining business has been through cycles before, and is exceedingly volatile. But analysts say they can't recall a more sudden, sharp decline in prices.

Of course, this slump is still in its early days. Prices could bounce back if China's housing market regains its vigor. After all, China, India and other developing nations still need massive helpings of copper, zinc and other metals as they strive to catch up to rich countries' living standards. China currently consumes only about one-fourth as much copper per capita as Germany.

Still, at current market prices, it's hard to make money running many mines, which have high labor, equipment and energy costs. About 30% of nickel mines and more than 15% of zinc mines have turned unprofitable due to falling prices.

Two weeks ago, North American Palladium Ltd. said it would lay off 350 workers and shut down production at it Lac des Illes mine near Thunder Bay in Canada because it couldn't turn a profit once prices fell to about $180 an ounce currently from a high of $582 as recently as March.

The pain from shutdowns like these is particularly acute in places that rely almost exclusively on mining for their well-being. Because of their odd locations -- mines are often in hard-to-reach places where they are the only major employers in town -- closures can decimate local economies.

Two weeks ago, Blue Note Mining closed its zinc and lead mine in Bathurst, a Canadian town of 12,000 or so perched on the edge of New Brunswick. Younger workers will probably leave town, says Mayor Stephen Brunet. But the closing is particularly tough for older workers, many of whom were laid off a few years ago.

"They have paid for their houses and aren't likely to move," he said.

Across Africa, many new projects that were to begin this year and next, including uranium, iron ore and titanium, are being put on hold. This is bad news for the continent, which had been enjoying a rare economic boom. In recent years, mining activity had helped propel growth rates to their highest levels in decades, offering new hope of an end to the continent's cycles of poverty.

But when commodities prices fall, investing in Africa becomes a hard sell again. While countries like Congo are sitting on lucrative mineral deposits, it and other large chunks of Africa lack the roads or ports needed to process and export those minerals. Many regions are also politically unstable or dangerous, further dissuading investors.

The economic spasms aren't limited to poor countries. Some economists fear the mining slump will help drag Australia into recession. Australia, one of the world's biggest producers of iron ore and nickel, has seen its currency weaken more than 30% since July against the U.S. dollar as the mining industry stumbles there.

Melbourne-based OZ Minerals Ltd. recently said it is contemplating some shutdowns, including possibly at its operation in the vicinity of Mount Isa, Australia, currently the second-largest open-pit zinc mine in the world. Big cutbacks could leave scores of towns across the dusty, forbidding Australian Outback with little or no other reason to exist.

The swift reversal is remarkable in an industry that saw its profits increase 20-fold in five years, climbing to $80 billion in 2007 from just $4 billion in 2002. Just a few months ago, miners were struggling to hire enough workers to keep up with unprecedented global demand.

Some companies were so desperate for equipment that they were forced to dig up old, discarded tires from garbage dumps to outfit their giant trucks because new tires were in such short supply. In South Africa, power companies were no longer able to provide enough electricity to keep the country's burgeoning mines running.

In the last major commodities downturn, in the late 1990s and early part of this decade, mining companies got clobbered. Prices for copper fell some 50% in the wake of the 1997 Asian financial crisis followed by the U.S. recession in 2001.

In 1998 and 1999, BHP (a predecessor of today's BHP Billiton) posted cumulative losses of nearly $3 billion and required a major restructuring before it could be revived. It mothballed major mines in Arizona and Nevada, while Rio Tinto laid off staff at its copper operations in Utah. Other companies went out of business.

The mining business didn't perk up again until demand in China began to take off around 2002 and 2003.

This time around, the biggest mining companies -- including BHP Billiton, Companhia Vale do Rio Doce, Anglo-American and Barrick Gold -- are likely to use this downturn to try to grab market share from smaller rivals, known as "junior" minors, that sprang up like mushrooms in recent years when it was easier to raise capital. While junior miners often carry heavy debt, the giant firms have built up formidable war chests over the past few years. Many are keeping an eye peeled to buy struggling smaller companies on the cheap.

The current pricing volatility has been intensified by the global financial crisis. Many hedge funds, pension funds and other investors desperate to raise cash as their stock- and bond-related holdings tumbled, rapidly sold their commodities holdings in recent months. That pushed down prices of copper, zinc and nickel more rapidly than in previous downturns.

Five years ago, nickel was selling for about $9,000 a metric ton. A year ago, that price had swollen to more than $40,000, in part because of demand, but also because so many hedge funds and other investors were piling in.

In recent months, demand for nickel has declined somewhat -- but cash-strapped investors like these have rapidly bailed out of their holdings. As a result, the price declines have far outstripped the rate of decline in actual demand for the metal. Nickel is now selling for about $11,600 a metric ton.

Ultimately though, the industry's problems are rooted in weakening demand, particularly in China, rather than the financial crisis.

China's soaring economy gobbled up unprecedented amounts of raw materials in recent years, as the country built skyscrapers and roads, cellphones and autos at an historic pace. With the urban migration of tens of millions of people spurring an epic construction spree, many analysts still believe the China metals boom could have a decade or more to run.

Now, however, China is suffering a one-two economic punch. The world is buying fewer of the goods cranked out by its factories, and China's own spooked consumers are retreating from the housing market.

As a result, China's economic growth is slowing sharply, to 9% in the third quarter from nearly 12% last year. Some analysts worry it could easily drop below 8% next year.

That's weak by China's recent standards, and many consumers are worried about the future. On a recent weekend in Beijing, hundreds of young families piled onto buses to tour new housing developments on the city's edge. But many have no plans to put money down just yet.

"I prefer to wait for a bit, until say the end of this year or early next year, in case the housing prices in Beijing continue to fall," said Xiao Yalin, a kindergarten teacher.

With so many people taking the same wait-and-see attitude, housing sales in China have collapsed: The volume of transactions has been dropping 40% to 60% nationwide in recent months, according to Macquarie Securities. In September, the volume of China's of new-construction fell 13%, its sharpest decline in a decade.

That decline hits mining companies right where it counts. A large chunk of China's metals demand is directly tied to construction, from the steel rebar that supports buildings to the aluminum that goes into new appliances.

China's steel output plunged 17% in October alone. That has led to an equally rapid reversal in the demand for iron ore. As of last month, the country had nearly three months worth of imports, or 89 million metric tons of ore, sitting unused at its ports, according to the China Iron & Steel Association.

Getting that ore off the docks depends in large part on getting China's reluctant home-buyers back into a buying mood. But people on the front lines, like Nie Xin, a director at real-estate agents E-House China in Beijing, aren't particularly optimistic. "We feel that the rebound won't come until 2010," he says. This market "is very cold right now."

NYT -- Oil Industry Sets a Brisk Pace of New Discoveries ..........................................

Oil Industry Sets a Brisk Pace of New Discoveries

By JAD MOUAWAD

The oil industry has been on a hot streak this year, thanks to a series of major discoveries that have rekindled a sense of excitement across the petroleum sector, despite falling prices and a tough economy.

These discoveries, spanning five continents, are the result of hefty investments that began earlier in the decade when oil prices rose, and of new technologies that allow explorers to drill at greater depths and break tougher rocks.

“That’s the wonderful thing about price signals in a free market — it puts people in a better position to take more exploration risk,” said James T. Hackett, chairman and chief executive of Anadarko Petroleum.

More than 200 discoveries have been reported so far this year in dozens of countries, including northern Iraq’s Kurdish region, Australia, Israel, Iran, Brazil, Norway, Ghana and Russia. They have been made by international giants, like Exxon Mobil, but also by industry minnows, like Tullow Oil.

Just this month, BP said that it found a giant deepwater field that might turn out to be the biggest oil discovery ever in the Gulf of Mexico, while Anadarko announced a large find in an “exciting and highly prospective” region off Sierra Leone.

It is normal for companies to discover billions of barrels of new oil every year, but this year’s pace is unusually brisk. New oil discoveries have totaled about 10 billion barrels in the first half of the year, according to IHS Cambridge Energy Research Associates. If discoveries continue at that pace through year-end, they are likely to reach the highest level since 2000.

While recent years have featured speculation about a coming peak and subsequent decline in oil production, people in the industry say there is still plenty of oil in the ground, especially beneath the ocean floor, even if finding and extracting it is becoming harder. They say that prices and the pace of technological improvement remain the principal factors governing oil production capacity.

While the industry is celebrating the recent discoveries, many executives are anxious about the immediate future, fearing that lower prices might jeopardize their exploration drive. The world economy is weak, oil prices have tumbled from last year’s records, corporate profits have shrunk, and global demand for oil remains low. After falling to $34 in December, oil prices have doubled, stabilizing near $70 a barrel. But if the world economy does not pick up, some analysts believe the price could fall again.

Oil companies contend that is not a prospect they can afford. Despite reaping record profits in recent years, many executives have warned that they need prices above $60 a barrel to develop the world’s more challenging reserves. In fact, some exploration activity has already slowed this year, as producers seek better terms from service companies and contractors.

It is not just oil that is benefiting from the exploration boom. Repsol, Spain’s biggest oil company, said this month that it had discovered what could turn out to be Venezuela’s biggest natural gas field. In recent years, companies have found substantial natural gas reserves in the United States, from shale rocks once believed to be impossible to drill.

“The No. 1 question that exploration teams have right now is, Where do we go next?” said Robert Fryklund, who ran the operations of ConocoPhillips in Libya and Brazil, and is a vice president in Houston at Cambridge Energy Research Associates.

Exploration spending swelled in recent years, partly to offset a doubling of costs throughout the industry — from steel prices to the cost of renting deepwater drilling rigs. A big issue confronting the industry now is how to drive down costs while maintaining a high level of exploration. On average, costs have fallen by 15 to 20 percent from their peak, according to petroleum executives.

Exploration remains a risky, and costly, business, where some deepwater wells can cost up to $100 million. From 30 to 50 percent of exploration wells find oil.

Some executives are also worried the world might face a shortfall in supplies in coming years if another decline in oil prices causes exploration to falter.

The chief executive of the French oil giant Total, Christophe de Margerie, has warned that such a supply crunch is possible by the middle of the next decade. “There could be a shortage of capacity,” he said.

His concerns echoed those of Abdullah al-Badri, the secretary general of the Organization of the Petroleum Exporting Countries, who said that lower oil prices also threatened investments by OPEC nations.

Saudi Arabia is also unlikely to expand its production in coming years because of the uncertainty clouding future oil demand, Ali al-Naimi, the kingdom’s oil minister, signaled earlier this month. Saudi Arabia is just completing a $100 billion program to increase its capacity to 12.5 million barrels a day, from around 9 million barrels a day just a few years ago.

Although they are substantial, the new finds do not match the giant fields discovered in the 1970s, like Alaska’s Prudhoe Bay, Ekofisk in the North Sea, or Cantarell in Mexico. They are also dwarfed by the last enormous discovery, the Kashagan field in the Caspian Sea, discovered in 2000 and estimated to hold over 20 billion barrels of oil.

“We have not seen another Kashagan, but still these finds are very material,”
said Alan Murray, the exploration service manager at Wood Mackenzie, a consulting firm in Edinburgh.

Since the early 1980s, discoveries have failed to keep up with the global rate of oil consumption, which last year reached 31 billion barrels of oil. Instead, companies have managed to expand production by finding new ways of getting more oil out of existing fields, or producing oil through unconventional sources, like Canada’s tar sands or heavy oil in Venezuela.

Reserve estimates typically rise over the life of a field, which can often be productive for decades, as companies find new ways of getting more oil out of the ground.


The industry’s record has improved in recent years, thanks to high prices. According to Cambridge Energy Research Associates, oil companies have found more oil than they produced for the last two years through a combination of exploration and field expansions.

“The appetite for opening new frontiers when prices were low in the 1990s was very small,” said Paolo Scaroni, the chief executive of Italy’s oil giant Eni. “Today, the biggest discovery of all is technology.”

One of the largest finds this year was made by a small producer, Heritage Oil, at the Miran West One field in the Kurdistan region of northern Iraq. It found nearly two billion barrels of oil and plans to drill a second well before the end of the year. While the central government of Iraq has had a hard time attracting investors to develop its huge fields, local authorities in Kurdistan have been successfully wooing foreign producers.

Meanwhile, in the Gulf of Mexico, BP’s discovery proves that the area remains one of the most promising oil regions in the United States. BP has estimated that the Tiber field holds four billion to six billion barrels of oil and gas, which would be enough, in theory, to meet domestic consumption for more than a year.

“In 30 years I’ve been in the business, the Gulf of Mexico has been called the Dead Sea countless times,” said Bobby Ryan, the vice president of global exploration at Chevron. “And yet it continues to revitalize itself.”
