CFTC&#8217-s Concept Release on the Appropriate Regulatory Treatment of Event Contracts

II. Commodity Options and Futures and the Attributes of Event Contracts

The Commission, with some exceptions, has exclusive jurisdiction over two relevant types of derivative instruments &#8212-commodity options and commodity futures contracts.

Section 4c(b) of the Act gives the Commission plenary jurisdiction over commodity options, and provides that &#8220-[n]o person shall * * * enter into * * * any transaction involving any commodity regulated under this Act which is of the character of, or is commonly known to the trade as, an option * * * contrary to any rule, regulation or order of the Commission[.]&#8221-

Section 2(a)(1)(A) of the Act provides that the Commission shall have exclusive jurisdiction with respect to accounts, agreements, and transactions (including options) involving contracts of sale of a commodity for future delivery.

Event contracts, depending on their underlying interests, can be designed to exhibit the attributes of either options or futures contracts.

A significant number of event contracts are structured as all-or-nothing binary transactions commonly described as binary options. 8 Binary event contracts typically pay out a fixed amount when an outcome either occurs or does not occur. The trading of such contracts can facilitate the discovery of information by assigning probabilities, through market-derived prices, to discrete eventualities. For example, a binary contract based on whether a particular person will run for the presidency in 2012, can pay a fixed $100 to its buyer if and only if that individual runs for the presidency in 2012. If the contract&#8217-s traders believe that the likelihood of the individual&#8217-s candidacy in 2012 is around 17 percent, the price of the contract will be around $17, and will approximate the market&#8217-s consensus expectation of the individual&#8217-s candidacy.

8 See, e.g., Intrade Prediction Markets, Current Events Contracts

In addition to binary event transactions, the term event contract has also been used to identify transactions, based on interests other than market prices, which resemble futures contracts. For instance, these types of event contracts can price consensus estimates of moving values, such as the number of hours the average U.S. resident spends in traffic or the share of votes that a particular candidate for political office may receive. Unlike binary transactions, and similar to any commodity futures contract, this type of contract creates continuous and ongoing obligations that are linked to moving measures or levels, as opposed to being dependent on the outcome of a single discrete occurrence.

III. The Commission&#8217-s Regulatory Purview

[…]

For the purpose of discussion and analysis, the types of event contracts that Commission staff has reviewed can be categorized, albeit imperfectly, as contracts that are based on narrow commercial measures and events, contracts based on certain environmental measures and events, and contracts based upon general measures and events.

Narrow commercial measures quantify and reflect the rate, value, or level of particularized commercial activity, such as a specific farmer&#8217-s crop yield.

Narrow commercial events, on the other hand, are events that might, in and of themselves, have commercial implications, such as changes in corporate officers or corporate asset purchases.

Environmental measures can be characterized as quantifications of weather phenomena, such as the volatility of precipitation or temperature levels, that do not predictably correlate to commodity market prices or other measures of broad economic or commercial activity.

By comparison, environmental events can include the formation of a specific type of storm, within an identifiable geographic region, the likelihood of which will not predictably correlate to commodity market prices or measures of broad economic or commercial activity.

General measures can be described as measures that are not commercial or environmental measures. As such, general measures do not quantify the rate, value, or level of any commercial or environmental activity and can, for example, include the number of hours that U.S. residents spend in traffic annually or the vote-share of a particular presidential candidate.

Similarly, general events, such as whether a Constitutional amendment will be adopted or whether two celebrities will decide to marry, can be described as events that do not reflect the occurrence of any commercial or environmental event. The category of general measures and events can be further divided into a multitude of subcategories, such as political or entertainment measures or events.

Since 1992, Commission-regulated exchanges have listed for trading a variety of commodity futures and options contracts with payout terms based on interests other than price-based interests. These contracts involve interests as diverse as regional insured property losses, the count of bankruptcies, temperature volatilities, corporate mergers, and corporate credit events. 12

While not strictly price-based, the interests underlying these contracts have been viewed by Commission staff as having generally-accepted and predictable financial, commercial or economic consequences.

In other words, unlike the interests that event contracts cover, these underlying interests have been viewed as measures and occurrences that reasonably could be expected to correlate to market prices or other broad-based commercial or economic measures or activities.

12 For example, the Chicago Board of Trade&#8217-s catastrophe single event insurance option contracts (which are no longer listed) paid out a fixed amount if and only if insured property damage exceeded $10 billion for a specific region during a specified interval of time.

The term event markets sucks -and the uncritical thinkers using this crappy term suck too.

Google: &#8220-event markets&#8221- &#8212- Funny enough, the first link is to the Futures Industry Association, which promoted the term&#8230- and the second to CFM, which advises not to use that term (see the bottom of the CFM frontpage). :-D

Just because 2 or 3 bureaucrats at the CFTC have decided to use that term does not mean that that term makes sense. It does not. &#8220-Event derivative markets&#8221- or &#8220-prediction markets&#8221- are better terms. It&#8217-s with great displeasure that I saw our own Mike Giberson (supposedly, a libertarian, and supposedly, a wannabe academic) followed the step of the CFTC like an obedient little poodle. :-D

Just because somebody in power says something stupid that makes no sense at all does not mean that you should swallow it and direct it straight to your stomach.

Use your brain to perform critical reasoning.

Via Ed, The Daily Mail:

The Daily Star reveals that some punters are set to earn more than half a million pounds after a total bet of ?971 was staked via BetFair on Nikki to win at 1000-1 shortly after she was voted out of the house. […]

Rumours of &#8216-insider dealing&#8217- on BetFair chat forums continue to surround the clued up gamblers who stand to win ?582,250. […]

That &#8220-Nikki&#8221- was evicted, an later on re-instated in the game.

Hence, the questions about the traders who did bet on her, after her eviction. Did they &#8220-know&#8221- something that the other traders didn&#8217-t?

On the other hand, it&#8217-s a constitutional right for Joe A. Doe to bet ?971 on a loser. Many do that every day at the horse race track. We should not accuse people of insider trading (or corruption) without any evidence.

BetFair employs many specialists in their &#8220-integrity team&#8221- to deal with such occurrences.

CFTC regulation and election contracts

No Gravatar

Insofar as event markets are within the CFTC&#8217-s jurisdiction, they would likely be approved as &#8220-excluded commodities&#8221-. Here is the relevant part of the definition within the Commodity Exchange Act:

(iv) an occurrence, extent of an occurrence, or contingency (other than a change in the price, rate, value, or level of a commodity not described in clause (i))
that is—
(I) beyond the control of the parties to the relevant contract, agreement, or transaction- and
(II) associated with a financial, commercial, or economic consequence.

With the putative terrorism and assassination markets, by their nature, it is impossible to reliably identify who might manipulate an outcome. It could be argued then that such contracts do not involve commodities and lie outside the jurisdiction of the CFTC.* The counterargument is that such markets are actually &#8220-exempt commodities&#8221-, defined broadly in the CEA as &#8220-all non-agricultural, non-excluded commodities&#8221-. This is something for the CFTC to clarify: are event markets &#8220-excluded commodities&#8221-, &#8220-exempt commodities&#8221-, or might they fall into either category depending on their specifics? Examples of exempt commodities are energy products, metals and quasi-currencies like energy, bandwidth and carbon credits. In practice then, if not by law, exempt commodities have involved something deliverable in units other than cash, although specific contracts might also be cash-settled.

It is a good bet then that the CFTC would classify event markets as excluded commodities. Additionally, invoking the &#8220-beyond the control&#8221- clause would be a very antiseptic way for the agency to repudiate markets based on terrorist events and the like, although they would risk losing the ability to punish similar markets that do not meet all criteria. Putting that issue aside for a moment and considering only the CFTC&#8217-s approval process, this treatment would bring up two problems with markets that the agency might want to regulate. Each of these problems has a solution.

First, wouldn&#8217-t election and policy markets also be disqualified by the clause? After all, a candidate could throw an election for profit, or perhaps more likely, engage in some sort of &#8220-point shaving&#8221-. Remember, these are not securities and thus not subject to insider-trading laws. The CEA, however, includes a section 13(f) prohibiting members of exchanges from trading on material nonpublic information obtained through their exchange duties. It is feasible to create similar trading restrictions at the regulatory level, by disallowing candidates, their staffs and proxies from trading.

Such trading prohibitions would reasonably ensure that no trader would be in control of the outcome of the contract. The CFTC could levy a special trading fee (much less than 1% notional) on such contracts to offset the relative work they might entail. The framework for such an arrangement could possibly be clarified on the CFTC&#8217-s next reauthorization. In a sense, it was unfortunate that their request for comments on event markets came so late in their recent reauthorization process. From another perspective, they ostensibly have until 2013 to exercise innovative, progressive policy.

Now, what if someone not barred from trading possesses damning information, photos, etc, on a candidate? By deciding whether or not to release that information, are they then &#8220-in control&#8221- of the contract&#8217-s outcome? It&#8217-s doubtful. Even though they might influence the contract&#8217-s outcome, they are not &#8220-in control&#8221- of it. The situation is similar to whether or not a trader, who might be aware of a new oil find or simply has a large account, is in control of that non-&#8221-excluded&#8221- commodity price. In general, the rules should be designed to elicit as much information as possible, falling short of allowing traders to decide a 0 or 100 settlement.

The second issue is the implicit assassination option in candidates&#8217- contract prices.** This issue could be easily dealt with, as Intrade does with their updated rules. Clearly this would be necessary with CFTC-regulated contracts, or else an unknown might be in control of their outcomes. The CFTC rule might work as follows. Upon a death, all contracts would be immediately cash-settled at their last price before the event. As soon as possible, an updated set of contracts would then begin trading so that no trader is able to profit or lose from the jump in prices. This process would be similar to traders simply rolling into a new contract maturity. It would be disruptive, but nothing to complain about compared to the tragedy of the situation. Small modifications to the rule could address scenarios where a candidate is incapacitated for some time during which their candidacy is uncertain.

A more challenging scenario is the possibility of a manipulation preceding the event such that the forced settlement locks-in profits, presumably just as market power is exhausted. Regulations could provide for an investigation of such situations, and the relevant transactions and profits shouldn&#8217-t be too hard to find with that level of scrutiny.

This framework addresses several of the questions posed in the CFTC&#8217-s concept release. That document and comments elsewhere seem to indicate a reluctance to expand jurisdiction to the point where sports markets and gaming might be included. Officials now and then harken back to the pre-CFMA economic purpose test, but that test could be effectively reconstituted for event markets with a policy decision such that those markets will only be approved as excluded commodities, subject to their specific &#8220-economic consequence&#8221- clause. In itself, that policy would not impinge on the agency&#8217-s ability to prosecute unauthorized exchanges in similar markets (and hopefully they will treat Intrade with some degree of amnesty given the ambiguous and arbitrary law of this country). While this policy would leave the door open even for regulated sports-based hedging markets, the CFTC could leave the prosecution of online sports and gaming exchanges to the DOJ and state authorities for now. The burden of the duty to prosecute illegally operating exchanges might be smaller than feared, and, again, the agency could levy a special fee on such regulated markets to offset demands on its resources.

These opinions perhaps pose more questions than they answer. The Commodity Exchange Act is broad enough to encompass jurisdiction over event markets. The CFTC seems unsettled that the language is too broad, but there are ways for them to calibrate their jurisdiction at the policy level.

* A market in research science claims would follow the same logic in terms of jurisdiction. Even without a no-action letter or public interest exemption, the chances seem very good that such an exchange could operate without interference if they stayed with small claims, did not advertise and did not accept trades from States where the predominant factor test does not apply.

** Let me condemn Hillary Clinton&#8217-s recent remarks as sinister and irresponsible.

Robust, the prediction markets are the best mechanism for aggregating information. Thus, companies should use them for assessing strategy and hedging risks.

[…] This leads to [Justin Wolfers]&#8216- claim that [prediction markets] are the best way to aggregate information. This is true of any given amount of information. Take three economists and make them trade out a market over their predictions for next month&#8217-s inflation number, he suggests, and they will arrive at a more accurate prediction than a poll of the same three economists. In a market, those with stronger conviction (or inside information) can express that conviction- those less confident will not be willing to stake money. […]

Prediction markets remain subject to the same weaknesses as other markets. The principle of &#8220-garbage in, garbage out&#8221- [*] applies. If there is only poor information to aggregate, they will be as wrong as everyone else. […]

It would make sense to incorporate these odds when making investments. […]

Excellent.

  1. Not a single word about InTrade-TradeSports fucking up its traders during the North Korea Missile episode.
  2. Although James Surowiecki is a great thinker overall, I&#8217-m not happy he served InTrade&#8217-s past forecasting successes in absolute terms &#8212-and not in terms of probabilities. That shows James Surowiecki can&#8217-t be the ultimate leader of the field of prediction markets. Robin Hanson, Justin Wolfers, Koleman Strumpf, Eric Zitzewitz, or even Emile Servan-Schreiber, would have not made that mistake.
  3. All prediction markets are not created equal. Spot that they go too far, saying terrorism prediction markets or earthquake prediction markets could serve a societal purpose. That is complete bullshit. That is pure hype. As I said yesterday, an analyst should check whether a given prediction market is really able of aggregating important information. Just because John Delaney wants to create a betting market to get money doesn&#8217-t mean that that given prediction market will be able to give sound forecasts. Otherwise, we would have prediction markets about future lottery outcomes and we would make a fortune out of that. :-D
  4. Spot that they put the emphasis on the easy translation between the 0&#8211-100 prices and the 0&#8211-100 probabilities. That puts BetFair&#8217-s model (based on those damn digital/decimal odds) out of the picture.

CFTC Requests Public Input on Possible Regulation of “Event Contracts” -a.k.a. event derivative markets, event futures markets, betting markets, bet markets, prediction markets

Via professor Eric Zitzewitz of Dartmouth (one of the top 5 economists studying prediction markets), the CFTC:

Release: 5493-08
For Release: May 1, 2008

CFTC Requests Public Input on Possible Regulation of “Event Contracts”

Washington, DC – The Commodity Futures Trading Commission (CFTC) is asking for public comment on the appropriate regulatory treatment of financial agreements offered by markets commonly referred to as event, prediction, or information markets.

During the past several years, the CFTC has received numerous requests for guidance involving the trading of event contracts. These contracts typically involve financial agreements that are linked to events or measurable outcomes and often serve as information collection vehicles. The contracts are based on a broad spectrum of events, such as the results of presidential elections, world population levels, or economic measures.

“Event markets are rapidly evolving, and growing, presenting a host of difficult policy and legal questions including: What public purpose is served in the oversight of these markets and what differentiates these markets from pure gambling outside the CFTC’s jurisdiction?” said CFTC Acting chairman Walt Lukken. “The CFTC is evaluating how these markets should be regulated with the proper protections in place and I encourage members of the public to provide their views.”

In response to requests for guidance, and to promote regulatory certainty, the CFTC has commenced a comprehensive review of the Commodity Exchange Act’s applicability to event contracts and markets. The CFTC is issuing a Concept Release to solicit the expertise and opinions of all interested parties, including CFTC registrants, legal practitioners, economists, state and federal regulatory authorities, academics, and event market participants.

The Concept Release will be published in the Federal Register shortly- comments will be accepted for 60 days after publication in the Federal Register.

Comments may also be submitted electronically to [email protected]. All comments received will be posted on the CFTC’s website.

WOW.

UPDATE: Eric Zitzewitz tells me that comments are sought 60 days after publication in the Federal Register. So, the deadline for commenting will be somewhat around June 30, 2008.
