Weather derivatives are financial instruments used to hedge against weather-related risks such as unseasonal temperatures, excessive rainfall or drought conditions. Businesses in some sectors are more likely to be impacted by climate variability, such as agriculture, tourism and energy markets. Weather derivatives are particularly useful in these sectors to mitigate the potential risks for businesses, investors and traders caused by weather fluctuations. In the EU, weather derivatives fall under the scope of the European Market Infrastructure Regulation when traded OTC, which means they are subject to certain regulatory reporting requirements.
What are Weather Derivatives?
Weather derivatives are financial instruments used by organisations and individuals to manage the financial impact of unexpected weather conditions. Unlike insurance, which requires proof of loss, weather derivatives pay out based on measurable weather outcomes such as temperature levels, rainfall, snowfall or drought levels, in a certain location over a specified period. Weather derivative contracts are structured around pre-agreed weather triggers, which makes them more flexible and often simpler than traditional insurance. A standard weather derivative contract has two parties:
- One party agrees to compensate the other if a specific weather event occurs (ie, temperature drops below a certain threshold)
- In return, the other party receives an upfront payment or premium
Payouts for weather derivatives are based on observed data such as heating degree days (HDD), cooling degree days (CDD) or daily temperature levels rather than any specified amount of financial loss. Unlike catastrophe insurance, which covers rare but extreme events such as hurricanes or earthquakes, weather derivatives are more commonly used to manage higher-probability, lower-severity risks. Weather derivatives are still less common than insurance products in the EU, but they are growing in popularity as climate change increases weather variability and the frequency of disruptive conditions. These instruments are common in several sectors:
- Agriculture: Farmers might want to hedge against frost risk by entering a contract that pays out if the temperature drops below a certain threshold during the growing season
- Energy: Energy companies can use weather derivatives to hedge against excess heating or cooling demand based on high or low temperature levels Tourism: Companies that rely on international tourism or outdoor events can hedge against unusually quiet periods or cancellations due to unseasonal weather
- Insurers: Insurers with structured policies based on specific weather events can offer weather derivatives as part of their broader risk management strategies
What are the Reporting Implications for Weather Derivatives?
In the EU, weather derivatives are classified as financial instruments and may fall under key regulatory frameworks, including the European Market Infrastructure Regulation (EMIR). When traded OTC, these contracts are treated as OTC derivatives and are therefore subject to EMIR’s reporting requirements. EMIR mandates that all derivative contracts, regardless of the underlying asset, be reported to an authorised trade repository (TR) by the end of the next working day (T+1). This includes contracts based on non-financial variables like temperature or rainfall, provided they meet the definition of a derivative under MiFID II and are not executed on a regulated trading venue. OTC weather derivatives have a bespoke structure and are often used bilaterally between organisations and financial institutions. Under EMIR reporting requirements, reports must include standardised information such as:
- Legal Entity Identifiers (LEIs) for both counterparties
- Notional value and underlying index (ie, temperature thresholds)
- Trade date and time of execution
- Settlement terms and valuation data
These reporting requirements help regulators to monitor market activity and increase transparency in EU derivatives markets. While weather derivatives are not as common in EU markets and still less widely used than insurance products, they are subject to the same regulatory oversight when traded as OTC financial instruments. Firms engaging in weather derivatives must understand their classification and reporting obligations to remain compliant and support transparency in the EU derivatives market.
