Liquidity Is King, or Why CME’s Failure in Cocoa Doesn’t Amount to a Hill of Beans

Filed under: Commodities,Derivatives,Economics,Exchanges — The Professor @ 9:55 pm

The WSJ reports that the CME Group’s new Euro-Denominated cocoa futures contract is floundering, due to a pronounced lack of liquidity. (h/t @libertylynx) The incumbent ICE Futures Europe Sterling-denominated and ICE Futures US USD-denominated contracts dwarf the CME contract’s volume, even though European hedgers face some currency risks in using these contracts.

This is not a surprise, not by a long shot. It is always very difficult for upstart contract to make inroads, let alone dominate, in competition with an established incumbent. Liquidity is king, and the established contracts have a liquidity advantage that new entrants almost never overcome, even if the new contract is superior on some dimensions.

The only real example of the displacement of an incumbent is Eurex’s wresting of the Bund contract from LIFFE in 1997-1998. That story, which I analyze in a forthcoming paper in the Journal of Applied Corporate Finance, is the exception that proves the rule.

First, because it was supported by German banks who direct a lot of order flow to it, Eurex (and its predecessor, Deutsche Terminborse) had a base of liquidity on which to build.

Second, because it was electronic, it was possible for Eurex to offer faster and easier access to US users once the CFTC approved Eurex’s application to install terminals in the US.

Third, and most important, Eurex exploited LIFFE’s smug complacency. Eurex aggressively cut fees, and LIFFE did not match: it was convinced that its superior liquidity, and the inherent superiority of floor trading, would prevent its customers from defecting to Eurex to save a few DM per contract in fees.

Wrong! As I document in the JACF paper, the liquidity cost difference between the markets wasn’t that great by 1997 (due to the German bank support and the influx of US customers), and taking into account the lower trading fees it was actually cheaper to trade on Eurex. Volume started to leak to Eurex, and the leak turned into a flood. LIFFE belatedly cut fees, but by then it was too late. The market had tipped completely to Eurex, and LIFFE had a near-death experience.

I can speak first hand of LIFFE’s overconfidence. In 1992, I produced a study for DTB that showed that its electronic market’s liquidity was comparable to that of the floor-based LIFFE. The study was not intended for release: it was commissioned to determine whether it was advisable for DTB to add a new membership type analogous to locals in order to improve liquidity. But the results were so surprisingly favorable for DTB that they released the study, much to the derision of LIFFE and the futures trading community generally, which was truly in the grip of the Cult of the Floor.

The CEO of LIFFE was quoted in the FT and Risk Magazine to the effect that I was an ivory tower academic who had no idea the way the real world works, because everybody knows the floor is more liquid and always will be. Real bulletin board material. Literally, in my case.

He who laughs last. When Eurex launched its assault on LIFFE in 1997, it distributed my 1992 study broadly. I doubt that had much of an impact on the final outcome, but it couldn’t have hurt.

The LIFFE CEO ended up resigning after LIFFE capitulated, and voted to close the floor and go electronic. I was a good boy. I resisted the very strong temptation to send him clippings of the FT and Risk articles.

Every other exchange learned a lesson at LIFFE’s expense, and responded to a fee cutting entrant by cutting fees immediately. For instance, the CBT saw off Eurex’s attempt to compete in the Treasury market in short order by cutting fees to zero, raising them after Eurex capitulated.

So CME shouldn’t feel bad. It has plenty of company in launching a contract that fails to make headway against an established incumbent. Indeed, the experience should be comforting, because it is the dominant incumbent in USD STIRs, govvies, equity indexes, FX, grain, precious metal, livestock, and energy futures. It benefits massively from the liquidity entry barrier. Compared to that, the failure to penetrate ICE’s cocoa monopoly doesn’t amount to a hill of beans.

Spoof Me Once, Shame on You: Spoof Me Twice, Shame on Me

Filed under: Commodities,Derivatives,Economics,Exchanges,Regulation — The Professor @ 6:41 pm

I’ve often written that HFT firms are the best able to detect spoofers, and to take preventative measures (which reduce the profitability of spoofing, and hence its prevalence). The whole business of HFT is extracting signals from orders and order flow, and trading accordingly. Spoofing is based on manipulating the order flow–in essence, injecting noise into it. HFT firms evaluate their executions, and attempt to identify patterns that predict both winning and losing trades. If spoofers systematically impose losses on HFT firms, eventually the latter will figure it out.

This is the first article that I’ve read that supports this contention:

Inside Ken Griffin’s $25 billion empire, Citadel’s cyber investigators had isolated a new enemy: spoofers.

It was late 2013, and at the firm’s Chicago headquarters, a team of researchers discovered that a rival company’s algorithm was outmaneuvering their automated trader. The algo was placing futures orders it had no intention of filling to entice firms like Citadel into the transactions, then canceling them, leaving Citadel with money-losing trades. Citadel’s plan: to pit its computers against the spoofer in a high-stakes duel over market manipulation.

. . . .

Vertex Analytics may have devised a way to make high-frequency trading more transparent and spoofing easier to detect. The Chicago-based technology firm can represent graphically every order and transaction on CME’s markets, obviating the need to go through pounds of paper searching for a telltale sequence of

Vertex’s approach was a revelation for Robert Korajczyk, a finance professor for more than 30 years at Northwestern University, where he’s studied asset pricing and liquidity.

“My first reaction to seeing the graphics capabilities was ‘This can’t be done,’” Korajczyk said. “However, Vertex can do it.”

. . . .

Citadel isn’t the only firm that took measures against spoofers without regulators’ help.

In 2012, Chicago-based HTG Capital Partners detected a pattern of large canceled orders followed by aggressive trades in the opposite direction that left them with losing positions, according to an affidavit released last month. The firm created tools to help identify when spoofing was taking place, the affidavit said.

Transmarket Group has created an “anti-manipulation guide” that tells traders how to spot spoofing, according to a copy seen by Bloomberg News. The Chicago-based firm lists specific examples of spoofing in the natural gas market on CME as part of the guide.

The article spends a lot of time discussing enforcement actions against spoofers, and the difficulties of making a case. Even ignoring my doubts (expressed in earlier posts) whether the social costs of spoofing really warrant expensive enforcement efforts, the fact that sophisticated and knowledgeable players have the incentive to detect this kind of conduct, and take defensive measures (and perhaps offensive–at least that’s what the description of Citadel “pit[ting] its computers” against spoofers suggests) means that the frequency and scale of spoofing activity is likely to decline significantly. It is a pathogen that found a niche, but the hosts’ immune systems are adapting, and it will become less dangerous in short order.

This isn’t true of all forms of manipulation, but the very nature of spoofing–which involves doing things that are intended to be detected–makes it vulnerable to detection and countermeasures. This means that the system tends to be self-correcting, and this mitigates the need for enforcement. Unfortunately, it appears that enforcement officials (both civil and criminal) think otherwise, and have prioritized the prosecution of spoofing. Combined with the outrageous overcharging and over-penalizing that I’ve mentioned before, this is a disturbing development.

Four Corners Offense: The Social History of Commodity Corners

I’ve been spending something of a busman’s holiday, reading this and that about commodity market corners in days long past. I started out looking into some of the big cotton corners at the beginning of the last century, namely the Brown-Hayne corner of 1903 and the Patten corner of 1910. These are the subject of a new book, The Cotton Kings: Capitalism and Corruption in Turn-of-the-Century New York and New Orleans. The book is entertaining history, but could use some more economics. It is journalistic in style, rather than analytical.

Reading about Patten’s cotton corner led me to read about his wheat corner of 1909, his corn corner of 1908, and his oats corner of 1902. Mr. Patten was a busy man.

And a reviled one. He was known as “The Wheat King,” whom the The Literary Review accused of  “The Crime of Making Bread Dear.” He was the model for the villain in the very influential D. W. Griffith short film, “A Corner in Wheat.”

This early short was one of the first films, if not the first, to address a serious social subject. Its theme would be very familiar today: the two Americas, rich and poorSergei Eisenstein admired Griffith, and employed his “parallel editing” technique (which he referred to as Griffith’s “montage of collision”): some film historians consider Griffith’s technique more subtle and less heavy-handed than Eisenstein’s.

(Unbeknownst to me when I was growing up in Evanston, Illinois, Patten was a longtime resident of the city, and its former mayor. He built a mansion there, and funded the Patten Gymnasium, where I swam in the summers.)

Patten was a nationally known figure. The Justice Department indicted him under the Sherman Act for his cotton corner, and the case attracted front page attention in national newspapers, including the New York Times, when it went to the Supreme Court. (Patten was fined $4000, or less than .1 percent of what he allegedly made in his corner. Not much deterrence effect there, eh?)

Patten was not alone in being a figure of national renown–and infamy. Commodity speculators were the banksters of their day. The Matt Taibbi of the 1880s, Henry Demarest Lloyd, wrote about cornerers at the Chicago Board of Trade in a famous essay. Frank Norris wrote a famous roman à clef, The Pit, based on the Leiter wheat corner of 1898.

In sum, in the last third of the 19th century and the first quarter of the 20th, commodity markets generally, and commodity market corners in particular, were the subject of intense interest. In some respects, it is not surprising that commodity corners were the subject of close journalistic coverage, serious fiction, social critical literature, and film during this era. Agricultural commodities were much more central to Americans as both consumers and producers. In 1900, 41 percent of the American workforce was employed in agriculture: now it is under 2 percent, and agriculture represents less than .7 of GDP. Half of American consumption spending went to food and textiles in 1900: a century later, that figure was down to 20 percent. Relatively speaking, the commodity derivatives markets (the Chicago Board of Trade, the Minneapolis Chamber of Commerce, Kansas City Board of Trade, the New York and New Orleans cotton exchanges, etc.) were more important and more developed that the capital markets, including the New York Stock Exchange, than is the case today: by the 1990s, when I was researching commodity exchanges and doing work with some, the commodity traders lamented that the explosion of financial futures had led the managements of exchanges to lose touch with the realities of commodities.

That said, one can see many echoes of the distant debates about and social criticism of commodity trading and corners in current controversies over financial markets. Just as outrage over the alleged excesses of the 2000s gave birth to the spate of post-Crisis financial regulation, fury over the Leiters and Pattens and Browns led to the first major regulations of financial markets in the United States: the Cotton Futures Act of 1914, and the Grain Futures Act of 1922 (which morphed into the Commodity Exchange Act, which is still with us, and which was amended by Frankendodd). Both Acts followed major government studies, the Commissioner of Corporations’ Report on Cotton Exchanges, and the Federal Trade Commission’s Report on the Grain Trade. Both of these are very well done, and provide very detailed descriptions of both the cash and futures markets. They are priceless resources. In some respects, because of them, we know more about the operation of commodity markets in the first decades of the 20th century than we do of their operation in the first decades of the 21st.

Maybe someday I’ll write a book about all of this, one that integrates the economics, history, and political economy. It’s of great personal interest, but not highly valued in the economics or finance professions today. I was amused when I came upon the link to an AER article about the Cotton Futures Act: it is beyond imagining that something similar would appear there today. But as I hope the foregoing shows, plus ça change, plus c’est la même chose. Issues of the relationship between financial markets and the real economy, the political economy of financial markets, and the influence of financial titans on political and judicial institutions, are still with us. In 1909, a film like A Corner in Wheat grappled with the social impact of finance in a very provocative and arguably simplistic way: in 2009-2015 movies like Too Big to Fail, Margin Call, and The Big Short do the same.

Don’t hold your breath, but maybe someday you’ll read about this in depth in print, rather than superficially in pixels.

I’m Not Spoofing You About Judicial Overkill

Filed under: Commodities,Derivatives,Economics,Energy,Exchanges,Regulation — The Professor @ 11:02 pm

Yesterday in a federal court in Chicago, Michael Coscia of Panther Energy Trading was convicted of six counts each of commodity manipulation and fraud for “spoofing.” Coscia faces decades in prison.

I haven’t seen the evidence, so I cannot judge whether Coscia did manipulate. For the purposes of this post I will stipulate that he did. But even given that stipulation, this entire exercise was judicial overkill and a travesty that can do serious damage to the markets.

What is spoofing? A trader puts in a large order (an offer, say) several ticks away from the best price in the market. He also places a small limit order on the other side of the market (a bid, in this example). If the market moves towards the large order, the spoofer cancels and replaces the order several ticks away from the new inside market. It is this cancellation that attracts all the attention. Much of the coverage says that the spoofer submits orders with the intent of canceling them.

That’s not the whole story though. The point of spoofing is to increase the odds that the small order is executed. After all, what would be the point of submitting orders that are never executed?

In the example, the large sell order is intended to convince others that the current price is too high. This may induce some bidders to cancel their bids, and others to cross the market and hit the bid. Both of these actions increase the odds that the spoofer’s small order will be executed.

So how does he make money? It can’t be by driving down the price persistently. The spoofer has bought: to profit, prices must rise subsequently. So, often the spoofer will reverse direction, putting in a big bid away from the market, and a small offer.

If spoofing works, the spoofer will repeatedly buy at the bid and sell at the offer, making the dealer’s turn. This will not cause the price to diverge persistently from where it would be, absent this conduct.

That’s apparently what happened with Coscia. He made a whopping $1K on the six episodes for which he was charged and convicted. He was just making a tick here and a tick there. And crucially, unlike the kinds of manipulation that cause real damage-corners, in particularly-he is not causing the price to be persistently inflated or depressed.

So who is hurt? Some people may be induced to trade when they wouldn’t have absent the spoofing. Their losses are approximately equal to the spoofers gains, on the order of a tick. And since some might have hit the spoofer’s bid even absent the spoofing, only a fraction of those with whom the spoofer trades are damaged.

Others who might be damaged are those who are fooled into canceling orders, and see the spoofer execute a trade they would have liked to if they hadn’t been fooled. The spoofer takes some of the profit they would have earned.

I find it hard to believe that these damages are are all that large. (They would also be hard to estimate because it is virtually impossible to identify who traded because of the spoofing, and who pulled a quote because of the spoofing, and gave up the opportunity to trade.) And regardless, this is exactly the kind of conduct that can be deterred using monetary fines.

This brings me to another bizarre aspect of these spoofing cases. Many of those who scream loudest about spoofing, like Eric Hunsader of Nanex, say: “SPOOFING IS SO OBVIOUS!!!! JUST LOOK AT THE DATA!”

As another case in point, I saw a Tweet embedding a .gif of someone’s TT trading screen, in which the quoted depth a couple of ticks above the inside market would rise and fall by 800 contracts or so. The Tweeter (I can’t find the Tweet) said something to the effect “look at this obvious spoofing.”

Well, I agree with the obviousness of it, but the implication of that is exactly the opposite of what Hunsader, the Tweeter, and presumably the DOJ and CFTC believe: If it so obvious, nobody is fooled. If nobody is fooled, it can’t affect trading behavior or prices. If it doesn’t affect trading behavior or prices, there is no economic harm. If there is no economic harm, it shouldn’t be prosecuted.

There is a law and economics take on this too. Classic Gary Becker analysis shows that draconian penalties-like 25 years per fraud charge and 10 years per manipulation charge-are justifiable if the probability of detection of a harm/crime is small. This is necessary to make the expected cost paid by the offender equal to the cost of the harm. But if the conduct is obvious, even only ex post, the probability of detection should be high, so penalties far greater than any harm are excessive. In this case, grotesquely excessive. (Furthermore, again pace Gary Becker, incarceration of a defendant who can pay the monetary value of the harm caused is a social waste, in the form of the cost of imprisonment, and the lost output of the convict.)

But it gets worse. The Coscia prosecution-and the popular condemnation of spoofing-focuses obsessively on the large rate of order cancellation. But perfectly legitimate market making strategies involve large rates of order cancellation, especially in volatile markets. They also involve buying frequently at the bid and selling at the offer. Given the Javert-like zeal of prosecutors, their dim understanding of trading, and the difficulty of explaining market making to a jury create the very real risk that a market maker could be charged, and convicted, and be punished severely, because he cancelled a lot of orders, and made the dealer’s turn all day long. This huge and very real risk will no doubt lead to less aggressive quoting (a market maker is less willing to quote aggressively if he is reluctant to cancel too often for fear of being accused of spoofing).

And who pays for that? Market users, including both institutional and retail traders, who take the liquidity market makers supply. Thus, you and me are harmed by overzealous prosecution of spoofing that threatens to demoralize legitimate, efficiency-enhancing trading.

This raises the very real possibility that the prosecution of actions that produce little economic harm will inflict a far larger harm. That is perverse.

What is particularly infuriating is that enforcement authorities are apparently incapable of prosecuting much truly damaging market conduct. Federal prosecutors are crowing over getting Coscia’s scalp, and the Chairman of the CFTC is using the verdict to intimidate would-be spoofers, but 6 years ago Federal prosecutors in Houston utterly botched the BP propane corner case (US v. Radley). That was a real manipulation that caused real damage. But the prosecutors totally flubbed the case, and the perps walked. Then there are those obvious manipulations that the Feds haven’t even bothered to prosecute (perhaps to spare themselves the embarrassment of flubbing another one.)

It reminds me of the old joke about the lawyer who said: “I lost the cases I should have won, and won the cases I should have lost. Therefore, on average, justice was done.”

No, actually, Mr. Lawyer: justice is never done if the guilty walk free and the innocent are punished. And sad to say, US manipulation law is perilously close to embodying that cynical joke.

The Fifth Year of the Frankendodd Life Sentence

Filed under: Clearing,Derivatives,Economics,Exchanges,Financial crisis,Politics,Regulation — The Professor @ 7:52 pm

Today is Frankendodd’s fifth birthday. Hardly time for celebration. It is probably more appropriate to say that this is the fifth year in the Frankendodd life sentence.

So where do we stand?

The clearing mandate is in force, and a large fraction of derivatives, especially interest rate and credit index derivatives are cleared. This was intended to reduce systemic risk, and as I’ve written since before the law was passed and signed, this was a chimerical goal. Indeed, in my view the systemic risk effects of the mandate are at best a push (merely shifting around the source of systemic risk), and at worse the net effects of the mandate are negative.

Belatedly regulators are coming around to the recognition of the risks posed by CCPs. They understand that CCPs have concentrated risk, and hence the failure of one of these entities would be catastrophic. So there is a frenzy of activity to try to make CCPs less likely to fail, and to ensure their rapid recovery in the event of problems. Janet Yellen has spoken on the subject, as has the head of the Office of Financial Research, Robert Dudley of the NY Fed, and numerous European regulators. Efforts are underway in the US, Europe, and Asia to increase CCP resources, and craft recovery and resolution procedures.

This is an improvement, I guess, over the KoolAid quaffing enthusiasm for the curative effects of CCPs that virtually all regulators indulged in post-crisis. But it distinctly reminds me of people madly sewing parachutes after the rather dodgy plane has taken off.

Further, these efforts miss a very major point. The main source of systemic risk from the clearing mandate derives from the huge liquidity strains that clearing (notably variation margin on a rigid time schedule) will create when the market is stressed. There has been some attention to ensuring CCPs have access to liquidity in the event of a default, but that’s not the real issue either. The real issue is funding large margin calls during a crisis.

Moreover, as I’ve also discussed, efforts to make CCPs more resilient can increase pressures elsewhere in the financial system (the “levee effect.”) Relatedly, regulators have not fully come to grips with the redistributive aspects of clearing–including in particular how netting, which they adore, can just relocate systemic risks.

I therefore stand by my prediction that a regulation-inflated clearing system will the source of the next systemic crisis.

Moving on, I called the SEF mandate the worst of Dodd-Frank. In the US, the majority of swap trades are done on SEFs, though mainly through RFQs rather than the central limit order books that Barney and Co. dreamed about in 2010.

There was never a remotely plausible systemic risk reducing rationale for the SEF mandate. Hence, if SEFs are inefficient ways to execute transactions, the mandate is all pain, no gain. As an indication of that this is indeed the case, note that virtually all European banks and end users stopped trading Euro-denominated swaps with US counterparties exactly when the mandate kicked in. The swaps mandate was too onerous, and anyone who could escape it did.

In a piece in Risk, I referred to the Made Available to Trade part of the SEF mandate the worst of the worst of Dodd-Frank. It made no sense to force all market participants to trade a particular kind of swap on SEFs just because one SEF decided to list it. Apparently that realization is slowly sinking in. The CFTC recently held a meeting on the MAT issue, and it seems as if there is a good chance that the CFTC will eventually determine what has to be traded on SEFs.

It is an indication of my loathing for MAT as it currently exists that I consider that an improvement.

Still moving on, Frankendodd was intended to reduce concentration and interconnectedness in the financial system. The actual result cannot really be called a mere unintended consequence: it was the exact opposite of the intended effect. Completely predictably (and predicted) the huge regulatory overhead increased concentration rather than reduced it. This is particularly true with respect to clearing. Gary Gensler’s dream of letting a thousand clearing firms bloom has turned into a nightmare, in which the clearing business is concentrated in a handful of big financial institutions, exacerbating too big to fail problems. And clearing has turned out to be the Mother of All Interconnections, because every big financial institution is connected to all big CCPs, and because pretty much everyone has to funnel the bulk of their derivatives trades through clearinghouses.

I could go on. Let me just re-iterate another risk of Frankendodd: standardization–the regulators’ fetish–is  a major source of systemic risk. Monocultures are particularly vulnerable to catastrophic failure, and the international regulatory standardization that was birthed in Pittsburg in 2009, and enacted in Frankendodd and MiFID and Emir, has created a regulatory monoculture. Some are grasping the implications of this. But too few, and not the right people.

I’ve focused here on the sins of commission. But there are also the sins of omission. Frankendodd did nothing about the Fannie and Freddie monster, which is coming back from the dead. F&F was a real systemic risk, but the same political dynamic that fed it in the 1990s and pre-2008 is at work again. Get ready for a repeat.

Frankendodd should have just focused on raising capital requirements for banks and other financial institutions with liquidity and maturity mismatches, and driven a stake through Fannie and Freddie. Instead, it sought to impose a detailed engineered solution on an emergent order. This inevitably ends badly.

So maybe it would be more accurate to say that we’re in our fifth year on death row. Someday the warden will come knocking.

Monkeys Fly in China

Filed under: China,Economics,Exchanges,Regulation — The Professor @ 5:56 pm

In the very early days of this blog, I told the story about what Chief Economic Advisor Beryl Sprinkel said on Black Monday, 1987, when a panicked Treasury Secretary James Baker wanted to close the stock market: “We’ll close these markets when monkeys fly out of my ass.” No monkeys flew, and the markets stayed open, eventually stabilized, and then recovered.

But many monkeys are flying out of many asses in China. Although the authorities have not closed the stock markets, individual companies have halted trading in their stocks: trading in more than one-half of the listings in China is currently suspended.

Halting trading more than for a short interval in order to resolve information asymmetries and permit the flow of liquidity to stocks that have just experienced an information event (as during a temporary stock halt in the US) is in general a bad idea. (Post-87, Greenwald and Stein wrote a paper published in the JOB laying out this argument.) An uncoordinated and extended halt of many stocks is a really horrible idea, because of the negative externalities. That is, uncoordinated flying monkeys wreak even more havoc than coordinated ones.

Halting trading in a large number of stocks increases selling pressure on stocks that are still trading. This happens for at least a couple of reasons. First, individuals who need to raise cash (e.g., to meet margin calls) are forced to concentrate their sales in the stocks that keep trading. This tends to concentrate selling pressure, rather than diffuse it. Second, individuals who want to rebalance their portfolios away from equity into cash or bonds have to concentrate their sales in the stocks that continue to trade. Again, this concentrates selling pressure.

This creates a vicious feedback loop. A number of companies halt trading, which forces selling pressure to spill over with greater force on other stocks, which leads some of these companies to halt trading, which intensifies selling pressure on other companies, and so on. The ultimate likely outcome is a protracted lockdown of the entire market. Protracted because who is going to be the firm to restart trading first, and risk having everyone sell the hell out of them?

The vaunted Chinese economic managers (ha!) have well and truly bungled this one. They should have prevented open-ended trading halts, or had a coordinated stoppage and restarting of trading. The coordination failure at work now is manifest.

Again, I believe that the sharp selloff is more of a symptom of a deeper economic problem than a potential direct cause of such a problem. The main adverse spillover that the stock selloff could cause is through the margin debt channel. Margin calls could lead to fire sales of illiquid assets. Again, the more stocks that are not trading, the more severe these fire sales in non-equity assets will be: this is another adverse consequence of uncoordinated monkey launches. Moreover, failures to meet margin calls will saddle the lenders (themselves often highly leveraged) with losses. Both of these channels could have adverse consequences in the brokerage, banking and shadow banking sectors. Their balance sheets are not that hale and hearty to begin with, and this kind of shock could spark broader financial distress throughout the sector.*

In other words, the stock market decline is less of a crisis in itself, than a potential catalyst to a crisis via informational and fire sale channels. And perversely, uncoordinated trading halts in the stock market are more likely to intensify than mitigate any such catalytic effect.

But the Mandarins know everything, so I’m sure it will turn out swell.

In the meantime, the Mandarins have a message for all investors in China. Good luck with that!

* Perhaps one could argue, as Michael Brennan did when trying to explain price limits in futures markets in the JFE in 1986, that halting trading could ease pressure on margin credit. I am skeptical though. Even if stocks stop trading, margin lenders are likely to demand additional security in current conditions. Indeed, trading halts that reduce the informational content of stock prices create a source of uncertainty to margin lenders which they are likely to compensate for by demanding additional margin based on their estimate of the stock price once trading recommences, plus a premium to compensate for the uncertainty.

See You In the Funny Papers

Filed under: Clearing,Commodities,Derivatives,Economics,Exchanges — The Professor @ 6:01 pm

Here’s a first. I appear in a comic strip history of the CME-ICE rivalry in Bloomberg Markets Magazine. Quite the likeness!

Other than the fact that I appeared at all, the most amusing part of the, er, article, is the panel depicting CME’s Terry Duffy getting the news that ICE was making a rival bid for CBOT via a note slipped under his hotel room door at the FIA at Boca at 0600. I had eaten dinner with Duffy and CME CEO Craig Donohue the night before. They were in a little better mood then than they were the next day.

Bloomberg’s Matt Leising called me at about 0630 to ask me about the development. That led to an appearance on Bloomberg TV, where I was interviewed right before Jeff Sprecher. He watched me give the interview, and was not pleased with my prediction that CME would eventually prevail, but have to pay a lot more: I saw him say to the woman next to him (who I later found out was his wife, Kelly Loeffler) “who is this guy?” That was exactly how it worked out though, and apparently there were no hard feelings because Sprecher spoke at a conference I organized at UH a couple of years later. Either that, or he didn’t connect me with “this guy.”

Evenhanded guy that I am, I invited Craig Donohue to speak at a conference a year or two after that. His speech was interrupted by some Occupy types (remember them?), whom my tiger of an assistant Avani and I bodily shoved out of the room while the rest of the audience sat in stunned silence (not knowing what was going on).

So yeah. My involvement with CME and ICE sometimes does sound like something out of the funny pages. Now it’s official.

Spoofing: Scalping Steroids?

Filed under: Derivatives,Economics,Exchanges,HFT,Regulation — The Professor @ 5:35 pm

The complaint against Sarao contains some interesting details. In particular, it reports his profits and quantities traded for nine days.

First, quantities bought and sold are almost always equal. That is characteristic of a scalper.

Second, for six of the days, he earned an average of .63 ticks per round turn. That is about profit that you’d expect a scalper to realize. Due to adverse selection, a market maker typically doesn’t earn the full quoted spread.  On only one of these days is the average profit per round turn more than a tick, and then just barely.

Third, there is one day (4 August, 2011) where he earned a whopping 19.6 ticks per round trip ($4 million profit on 16695 buy/sells). I find that hard to believe.

Fourth, there are two days that the government reports the profit but not the volume. One of these days is 6 May, 2010, the Flash Crash day. I find that omission highly suspicious, given that this is the most important day.

Fifth, I again find it odd, and potentially problematic for the government, that it charges him with fraud, manipulation, and spoofing on only 9 days when he allegedly used the layering strategy on about 250 days. How did the government establish that trading on some days was illegal, and on other days it wasn’t?

The most logical explanation of all this is that Sarao was basically scalping-market making-and if he spoofed, he did so to enhance the profitability of this activity, either by scaring off competition at the inside market, or inducing a greater flow of market orders, or both.

One implication of this is that scalping does not tend to cause prices to move one direction or the other. It is passive, and balances buys and sells. This will present great difficulties in pursuing the manipulation charges, though not the spoofing charges and perhaps not the fraud charges.

The IECA Libels Me: I Am Oddly Flattered

Filed under: Commodities,Derivatives,Economics,Energy,Exchanges,Politics,Regulation — The Professor @ 10:22 am

The Industrial Energy Consumers of America has submitted a comment letter on the CFTC’s position limit rule making. The letter contains this libel:

If one looks at the agenda from the February 26, 2015 meeting (see below), other than CFTC presenters, every presenter has views that are not consistent with CFTC action to set speculative position limits. Professor Pirrong has a long history of client paid studies in this area and will need to identify who paid for the underlying data and study for his results to be credible on this subject.

If “this area” is the subject of speculation and position limits, this statement is categorically false. I have not done one “client paid study” on these issues. Period.

In fact, most of my writing on speculation has either been in my academic work (as in my 2011 book), or here on the blog. I have been arguing this issue on my own time.

Actually, I did do one client paid study on these issues about 11 or 12 years ago. For the IECA, in fact, which was just certain that the NYMEX’s expanded accountability limits for natural gas had caused volatility to increase. They hired me to study this issue. I did, using methods that I had employed in peer reviewed research, and found that IECA’s firm beliefs were flatly contradicted by the data: data that IECA paid for, analyzed using methods that were disclosed to it. IECA decided not to release the study. Surprise, surprise. So IECA knows from direct experience that my opinions are not for sale.

So just who here is hiding something? Hint: it ain’t me.

I could provide other examples. The GFMA study on commodity traders is a well known case: it was written up in the Financial Times. Another example that is not as well known was my work on a project for the Board of Trade in 1991-1992, in which I studied the delivery mechanism for corn and soybeans. (The resulting report was published as Grain Futures Markets: An Economic Appraisal.) I concluded that the delivery mechanism was subject to manipulation, and recommended the addition of delivery points at economic par differentials to Chicago. This was not the desired answer. On the day I presented my results to the committee of the CBT that commissioned the study, the chief economist of the exchange pressured me to change my recommendations. I refused. The meeting that followed became heated. So heated, in fact, that the head of the committee and I almost literally came to blows when I refused to back down: committee members from Cargill and ADM actually took the guy bodily from the room until he calmed down.

So the track record is abundantly clear: I call them like I see them, even if it isn’t what the client wants to hear.

In fact, it is IECA’s ad hominem that lacks credibility. My white papers for Trafigura are not related to the issue of speculation at all. To the contrary, they are related to the issue of physical commodity trading. I did a study for CME in 2009 on the performance of the WTI futures contract. Nothing related to speculation. Data sources disclosed, and the methodologies are clearly set out. Again, if IECA has specific critiques of any of these analyses, bring it on. Anytime. Anywhere. And they can leave their libelous insinuations behind.

Perhaps IECA head Paul Cicio is still sore over how I smacked him around at a House Ag committee hearing in July 2008. Cicio said it was obvious that speculation had inflated energy prices. He used the metaphor of a swimming pool: if a bunch of speculators jump in, it has to raise the water level. I retorted that this shows the exact opposite, because all the speculators get out of the pool before contracts go spot. Long speculators are sellers of futures as delivery approaches, meaning they are out of the pool (the physical market) as delivery approaches, and hence can’t be inflating spot prices.

If Cicio is still sore, all I have to say is: Get over it.

To reiterate: IECA’s statement in a document submitted to a government regulatory agency is categorically false, and libelous.

And oddly flattering. You don’t go out of your way to libel the irrelevant. The fact that this organization feels compelled to slur me by name and attack my credibility (even though the attack is false) means that they must believe that I pose a threat to them. I sure as hell hope so.

Word to the wise. Don’t bring a wet noodle to a gunfight. (I cleaned that up.) You’re going to lose.

BATS in the OCC’s Belfry?, or The Perils of Natural Monopoly Regulation, CCP Edition

Filed under: Clearing,Derivatives,Economics,Exchanges,Financial crisis,Regulation — The Professor @ 11:13 am

The Options Clearing Corporation (“OCC”) and the exchanges that own it (Chicago Board Options Exchange, Incorporated, International Securities Exchange, LLC, NASDAQ OMX PHLX LLC, NYSE MKT LLC, and NYSE Arca) are embroiled in a dispute with virtually everyone else in the options business regarding its new capital plan. Pursuant to its designation as a “Systemically Important Financial Market Utility” (“SIFMU”) under Frankendodd, OCC was required to boost capital from $25 million to nearly $250 million. Part of this will be obtained through retained earnings, with an additional $150 million via a capital injection from the four owner-exchanges. In addition, CBOE et al promise to inject up to $117 million in the event of “unexpected losses”, which would be most likely to occur during a financial crisis.

In return, the owner-exchanges receive in essence preferred stock, which pays a dividend in perpetuity. The exact amount of the dividend is not known publicly, but those objecting to the plan (including BATS and KCG) claim that it could be as much as 16-19 pct, at least in the first few years of the plan’s operation.

Non-owner exchanges like BATS and market users like KCG are furious, claiming that the the capital plan allows OCC’s owners to “monetize” the rents accruing to its status as the monopoly clearer for options transactions in the US. They believe that OCC will pay for the dividend by charging super competitive fees that will impair competition among exchanges (advantaging the owner exchanges over the non-owners) and will burden market users.

This is a difficult issue, the nature of OCC. Here are some thoughts:

1. OCC is a regulated monopoly, and arguably a natural monopoly.This creates the traditional conflict between the owners of the utility and its customers, which include other exchanges that aren’t owners (like BATS) and clearing firms and market users (like KCG). This is in many ways very similar to a dispute between a traditional electric utility and its ratepayers heard before a state utility commission, with the exception that this is before the SEC.

2. Like a traditional are case involving a regulated utility, the dispute here is over what is a fair rate of return on capital. BATS and KCG are objecting to the rate of return the 4 exchange owners of OCC are being promised for their capital contribution, and the process by which the SEC approved this rate of return.

3. It is particularly challenging to determine a “fair” rate of return on this capital because of the unique risks that the OCC exchanges are assuming. This capital is at risk of taking a big hit, and the owner-exchanges are potentially obligated to make additional capital contributions, during periods of financial crisis (the “dire circumstances”) referred to in BATS’s letter to the SEC. This tends to make this capital very expensive, and it should therefore earn a relatively high rate of return (high dividend). Capital that has bad returns when the market is doing poorly overall-“high beta”, if you will-is expensive capital. The type of capital being provided is fraught with wrong-way risk: it is likely to take a hit precisely when the capital suppliers are least able to afford it. Determining how much of a risk premium is warranted is a challenge, because of the exceptional nature of the risk. In essence, the exchanges are assuming tail risk, i.e., the risk of exceptional events, and it is inherently difficult to evaluate and price these risks.

4. The other exchanges and firms like KCG benefit from the risk bearing capital supplied by the owner exchanges. Otherwise, they would have to bear the risk. But of course they would like to underpay for this benefit, just as the owner exchanges might want to overcharge for it.

5. In other words, this situation is tailor made for disputes. Monopoly rate setting to determine fair rates and a fair rate of return on capital with very unusual and hard to evaluate risks.

6. The fears about the effects of pricing on inter-exchange competition in execution service are misdirected. Yes, it is possible that the owner exchanges will capture monopoly rents accruing to the OCC’s dominant position, but traditional “one monopoly rent” analysis implies that they don’t have an incentive to use OCC pricing power to advantage their competitive position in execution services. Indeed, the opposite is true.

This also highlights some organization, ownership and governance issues that I addressed in my research on exchanges that culminated in my 2000 JLE piece. Exchanges (and clearinghouses) have market power, and serve disparate and heterogeneous interests. They can use pricing to redistribute rents (which accrue in part due to market power) from one group of intermediaries to another. Not-for-profit status and mutual ownership (having the exchange or CCP operate as a non-profit “utility” serving disparate intermediary-owners is a way of reducing rent seeking and mitigating the use of pricing to redistribute rents.

But non-profit, mutual organization comes at a cost. It requires highly participative, committee-heavy governance that slows decision making and often creates gridlock that makes it difficult for the exchanges/CCPs to respond to technology, regulatory, or market shocks. (Look at the CBT in the 1990s and early-2000s if you want an example.) If everybody has a voice and a vote, it is very difficult to get things done.

In sum, “financial market utility” pricing and governance is inherently messy and controversial.  It has all of the problems associated with public utility regulation, and then some. The problems are particularly daunting when it comes to capitalizing, allocating and pricing the systemic and wrong way risks that CCPs bear. Given these complexities, I won’t venture an opinion here, except to say that (a) I can see both sides of the argument here, and (b) this ain’t going away anytime soon.
