Section 2: Price Reporting Agency

The official weather data that is used to settle our contracts is published by government weather agencies 

and then supplied to us from Speedwell Settlement Services Ltd. (SSS). In the case of the United States, 

the National Weather Service (NWS), Federal Aviation Administration (FAA), the Department of Defense 

(DoD), and the National Oceanic and Atmospheric Administration (NOAA) are responsible for the 

measurement, recording and issuance of the data. Weather stations used for CME weather contracts are 

located at major airports or government owned properties having 24 hour/365 day security measures in 

place to insure the accuracy of the data being reported. Similar to the US, European and Asian governments 

have implemented similar systems and collect the data in the same way, with the same authority and 

oversight.

These weather stations serve a vital function to air traffic safety around the world. Data readings from these 

stations are used to determine such things as flying and de-icing conditions. Therefore, the accuracy and 

security of these instruments are a high priority for these government agencies. Instrument placement is 

usually out on the property in remote secure locations, so as not to be affected by jet engine or tarmac heat 

radiation and most importantly human tampering. 

Settlement Data

Raw Data Weather Elements that have been processed to produce Certified Data, and when needed, 

Calculated Data.

Data Certification

Data Certification involves the process of detecting data problems (Gross Errors and Missing Data) and 

then correcting those problems by removing and replacing problem values with Estimated Values. 

As weather data is being released, a number of weather data suppliers are monitoring the data for any 

unusual readings. If a reading were to be an outlier or missing it would be reported to the issuing agency 

to verify for accuracy and/or correction. Weather data suppliers, such as Speedwell, not only monitor the 

specific CME weather locations, but also surrounding weather stations. They use surrounding weather 

stations as one means to verify for the accuracy of data being issued by the reporting agency. Speedwell 

is an industry leader in weather-related data to the futures and OTC markets. 

Section 3: Compliance with Core Principles

The Exchange reviewed the designated contract market core principles (“Core Principles”) as set forth in 

the Commodity Exchange Act (“CEA” or “Act”) and identified that the following Core Principles may be 

impacted by this initiative as follows:

• Compliance with Rules: Trading in the Contracts will be subject to all CME Rules, including 

prohibitions against fraudulent, noncompetitive, unfair and abusive practices as outlined in CME 

Rule Chapter 4, the Exchange’s trade practice rules, the majority of which are contained in Chapter 

5 and Chapter 8 of the CME Rulebook, and the dispute resolution and arbitration procedures of 

CME Rule Chapter 6. As with all products listed for trading on one of CME Group’s designated 

contract markets, trading activity in the Contract will be subject to monitoring and surveillance by 

CME Group’s Market Regulation Department. The Market Regulation Department has the authority 

to exercise its investigatory and enforcement power where potential rule violations are identified.

• Contracts not Readily Subject to Manipulation: The Contracts are not readily subject to 

manipulation because of their structural attributes and reliance on government supplied data. Final 

settlements are based on official weather data that is published by government weather agencies 

and supplied to the Exchange by a single PRA, Speedwell Settlement Services Ltd. In the case of 

the United States, the National Weather Service (NWS), Federal Aviation Administration (FAA), the 

Department of Defense (DoD), and the National Oceanic and Atmospheric Administration (NOAA) 

are responsible for the measurement, recording and issuance of the data. Weather stations used 

for CME weather contracts are located at major airports or government owned properties having 

24 hour/365 day security measures in place to insure the accuracy of the data being reported. 

Similar to the U.S., European and Asian governments have implemented similar systems and 

collect the data in the same way, with the same authority and oversight. 

• Prevention of Market Disruption: Trading in the Contracts will be subject to the rules of the 

Exchange, which include prohibitions on manipulation, price distortion, and disruption to the cash 

settlement process. As with any new product listed for trading on a CME Group designated contract 

market, trading activity in the option contract proposed herein will be subject to monitoring and 

surveillance by CME Group’s Market Regulation Department.

• Position Limitations or Accountability: The speculative position limits for the Contracts as 

demonstrated in this submission are consistent with the Commission’s guidance.

• Emergency Authority: As with all CME Group futures and options product, the Exchange shall 

have full authority to act appropriately and as necessary in emergency situations. 

• Availability of General Information: The Exchange will publish on its website information in 

regard to contract specifications, terms, and conditions, as well as daily trading volume, open 

interest, and price information for the Contracts. The Exchange will issue a Special Executive 

Report (“SER”) regarding the launch of the Contracts. The SER will also be posted on the CME 

Group website.

• Daily Publication of Trading Information: The Exchange will publish contract trading volumes, 

open interest levels, and price information daily on its website and through quote vendors for the 

Contracts.

• Execution of Transactions: The Contracts will be listed for trading on the CME Globex and for 

submission of clearing through the CME ClearPort platform. The CME Globex trading venue 

provides for competitive and open execution of transactions and affords the benefits of reliability 

and global connectivity.

• Trade Information: All requisite trade information for the Contracts will be included in the audit trail 

and is sufficient for the Market Regulation Department to monitor for market abuse. 

• Financial Integrity of Contracts: The Contracts will be cleared by the CME Clearing, a derivatives 

clearing organization registered with the CFTC and subject to all CFTC Regulations related thereto.

• Protection of Market Participants: CME Rulebook Chapters 4 and 5 set forth multiple prohibitions 

that preclude intermediaries from disadvantaging their customers. These rules apply to trading in 

all of the Exchange’s competitive trading venues.

• Disciplinary Procedures: Chapter 4 of the Rulebook contains provisions that allow the Exchange 

to discipline, suspend or expel members or market participants that violate the Rulebook. Trading 

in the Contracts will be subject to Chapter 4, and the Market Regulation Department has the 

authority to exercise its enforcement power in the event rule violations in these products are 

identified.

• Dispute Resolution: Disputes with respect to trading in the Contract will be subject to the 

arbitration provisions set forth in Chapter 6 of the Rulebook. Chapter 6 allows all non-members to 

submit a claim for financial losses resulting from transactions on the Exchange to arbitration. A 

member named as a respondent in a claim submitted by a non-member is required to participate 

in the arbitration pursuant to Chapter 6. Additionally, the Exchange requires that members resolve 

all disputes concerning transactions on the Exchange via arbitration.

Pursuant to Section 5c(c) of the Act and CFTC Regulation 40.2(a), the Exchange hereby certifies that the 

listing of the Contracts complies with the Act, including regulations under the Act. There were no substantive 

opposing views to this proposal.

The Exchange certifies that this submission has been concurrently posted on the Exchange’s website at

http://www.cmegroup.com/market-regulation/rule-filings.html.

Should you have any questions concerning the above, please contact the undersigned at 212-299-2200 or

Cash Market Overview and Deliverable Supply Analysis

Position Limit/Accountability Levels 

The Contracts will mirror the currently listed weather futures and options contracts with single month 

accountability levels of 10,000 contracts. These changes will be reflected in the position accountability table 

in Chapter 5. 

The 10,000 per month contract accountability level for similar weather products has been previously vetted 

with the CFTC. Note that Section 151 of the Act was vacated and reverted back to Section 150, which 

does not have an interpretation for position accountability for Alternative products. The CFTC previously 

acknowledged that weather is unique and that it is an excluded commodity and has no deliverable supply. 

At that time, CME noted the following: 1) due to the secured locations of the recording instruments, major 

airports, the index is not easily susceptible to manipulation and 2) a number of weather data suppliers are 

monitoring the data being released by these governmental agencies and any errors would most likely be 

reported and corrected promptly by the reporting agencies.

Cash Market Overview

Heating Degree Days (HDD)/Cooling Degree Days (CDD) and Cumulative Average Temperature (CAT) 

contracts are employed by a wide variety of enterprises, largely operating in the context of the energy 

industry, to manage their temperature related risks. 

Energy companies, for example, have been known to sell HDD or CDD contracts to manage the risk of 

diminished revenues under mild weather conditions, noting that the quantity of energy sold is heavily 

contingent upon consumer demand driven by temperatures. Large scale energy consumers including 

automobile manufacturers and large residential building operators may buy HDD or CDD contracts to hedge 

against the risk of rising utility costs under extreme weather conditions. 

Retailers whose sales are sensitive to weather conditions might control inventory costs more effectively 

through the use of HDD or CDD contracts. Beer consumption reaches a seasonal peak in the summer and 

cool weather can put a dent in beer sales. “the 2000 Preliminary Report for SABMiller, “History shows that 

on a summer day with the temperature over 25 degrees Celsius, sales can be more than 50% greater than 

on a day where the temperature is under 20 degrees... ” 

Utility companies may utilize HDD or CDD contracts to guard against “volumetric risks.” These volumetric 

risks are based upon the quantity of energy that might be expected to be marketed throughout the course 

of a heating or cooling season. These transactions rely upon the intuitive and well-documented relationship 

between power consumption and temperature extremes. 

Thus, if the daily average temperatures during the course of a winter season were abnormally high, utility 

firms might face depressed demand for heating. Utilities have traditionally increased consumer prices to 

offset lower retail consumption volume. However, intensifying competition caused by ongoing deregulation 

has made it increasingly difficult for utilities to raise prices arbitrarily. Therefore, it becomes necessary for 

utility firms to address volumetric risks using other means such as HDD or CDD contracts. 

Proper use of temperature related contracts not only enables utility firms to stabilize revenue streams but 

may also be used to provide at least a partial hedge to the cost side of the equation. Note that most utility 

firms operate under inherent capacity limitations. Electricity represents a non-storable commodity. If 

temperature suddenly rises or declines dramatically, utility firms may need to deploy less efficient 

generators to meet the sudden jump in demand or may be compelled to purchase electricity from the power 

grid in the face of soaring demands and rising prices. This implies that energy prices may increase, and 

transmission costs may grow simultaneously. In this case, utility firms may find both weather derivatives 
15

and energy contracts useful to stabilize their economic outcomes, i.e., to hedge both volumetric and costbased risks. 

Weather Market Overview

It has been estimated that over 2/3 of the global economy is impacted either directly or indirectly by weather 

conditions. The impact that weather has on businesses such as energy and agriculture is particularly acute. 

However, not only energy and agriculture observe the weather conditions. The lists of other economic 

sectors that are affected by the weather include construction and transportation sectors that have to 

contend with delays and budget overruns. The retail and entertainment sectors face similar challenges 

when weather turns unfavorable. A retailer may have stocked up on winter clothing only to have the season 

be unseasonably warm, causing markdowns at the end of the season to move merchandise, and incurring 

a loss. Entertainment such as concerts, municipal parades, ski resorts, amusement parks etc. can be 

impacted by rain, cold and heat translating into lost revenue. 

In addition to the commercial market participants like utility companies, some of the most active participants 

in the existing weather markets are insurance and reinsurance companies. Reinsurance companies, for 

example, offer clients a path to transfer their weather-related risk, and are then able to lay off a portion of 

that risk by participating in our weather futures and options markets. Hedge funds, pension funds, and asset 

managers that are looking for assets that are uncorrelated to their current portfolio holdings are also active 

participants in weather futures and options markets.
