The Channels of Transmission
The impact of weather on the agricultural markets
The dominant transmission channel: the supply side
The impact unfolds relatively slowly over time, except for some extreme event
Extremely cold weather in Florida affecting orange juice market
Freeze in the coffee producing regions
The potential for systemic impact due to long-term weather trends (Pinot Noir from Scotland?)
The impact on the demand side: local and short-term
The impact of weather on the agricultural markets was recognized in the relatively early stages of development of the futures exchanges

Words of Wisdom From the Past
“So much for the financial conditions.
The spring had been backward, cold, bitter, inhospitable, and Jadwin began to suspect that the wheat crop of his native country, that for so long had been generous, and of excellent quality, was now to prove—it seemed quite possible--scant and of poor condition. He began to watchthe weather, and to keep an eye upon the reports from the little county seats and "centres" in the winter wheat States. These, in part, seemed to confirm his suspicions.
From Keokuk, in Iowa, came the news that winter wheat was suffering from want of moisture. Benedict, Yates' Centre, and Douglass, in southeastern Kansas, sent in reports of dry, windy weather that was killing the young grain in every direction, and the same conditions seemed to prevail in the central counties. In Illinois, from Quincy and Waterloo in the west, and from Ridgway in the south, reports came steadily to hand of freezing weather and bitter winds. All through the lower portions of the State the snowfall during the winter had not been heavy enough to protect the seeded grain. But the Ohio crop, it would appear, was promising enough, as was also that of Missouri. In Indiana, however, Jadwin could guess that the hopes of even a moderate yield were fated to be disappointed; persistent cold weather, wintercontinuing almost up to the first of April, seemed to have definitely settled the question.”
Frank Norris (1870-1902), “The Pit,” New York, 1903

The Channels of Transmission (2)
The channels of transmission in the case of energy markets: primarily through the demand side
The impact on the supply side: primarily through specific events of varying magnitude, both in terms of scope and duration
Hurricanes
Precipitation impact on hydro power
Special local events
The events require good understanding of local conditions
The impact varies from long-term to short-term and fairly local
Fog in the Houston Ship Channel
High waters of the coast of California
Low water level in the Rhine river
Wells freeze-offs

The Channels of Transmission (3)
The challenge: weather forecasting for an energy trading operation
Practically everybody has the access to the same source data and analytical skills (for a price)
The competitive advantage can be acquired through:
Better interpretation of the conflicting forecasts (when the models diverge)
Improved skills in the process of selection of the weather forecasting firms
Moving up the supply chain to beat the competition
Faster acquisition, processing, visualization, and delivery of the weather information
Elimination of some links in the supply chain
Direct acquisition of the model results and atomic weather data
Most important: better understanding of the impact of weather on the energy markets, contingent on other conditions (trading positions, conditions of the energy infrastructure)

Weather Function in Energy Trading
Financial firms trading agricultural futures had weather teams supporting traders
Many weather analysts made contributions to energy trading in free time or when market conditions required their involvement
The first energy weather group was started by Enron
The Enron’s move was quickly replicated by the rest of the industry
The weather group was considered to be critical to the success of Enron trading

WEATHER DERIVATIVES

Weather Derivatives: Definition
A special version of weather insurance
Structured as derivative transactions
Regulatory considerations were the most compelling reason
Designed to hedge the risk of low severity, high probability events
By definition, actively traded on multiple platforms
A very successful take-off
The merchant energy industry used conditional probability distributions (unlike some counterparties in the insurance industry)
Some companies exploited successfully the human island phenomenon and data errors
Very limited repeat business

Weather Derivatives: The Future
My opinion: it’s not a viable business, as opposed to highly structured, customized weather insurance
The reasons:
Weather derivatives put on head the very principle of weather derivatives (the few will pay for the losses of the many instead of the many paying for the losses of the few)
The high probability events represent permanent and recurring conditions of doing business and are most effectively addressed by incorporating the cost in the price of a product
The cash flow smoothing aspect of weather derivatives: the premiums are effectively capped by interest rates

In-house Modeling
Some energy trading organizations move to direct acquisition of certain raw or intermediate data
Model outputs
Certain critical data sets
For example, sea surface temperatures
It can not be excluded that at some point some companies will engage in direct modeling of weather and/or computational activities
Will the market size justify this effort?

Algorithmic Trading
Several energy trading organizations are experimenting with trading strategies based on data mining
Search for the patterns of markets response to the weather data
Automatic execution of transactions
The challenges
The difficulty of identifying and capturing all the relevant data
The reaction to the weather data depends on many factors, which may not be measurable
Example: positions held by other traders
The volume may not be sufficient to bother
