Energy companies, hedge funds, and commodity traders increasingly turn to weather derivatives as a financial tool to navigate and capitalize on the growing frequency of extreme global weather events.
These instruments offer a unique way to hedge against or profit from the unpredictable effects of climate change, and recent data highlights a substantial surge in their usage.
Significant Growth in the Weather Derivatives Market
The Chicago Mercantile Exchange (CME) has witnessed a remarkable surge in weather futures and options trading. Comparing this year’s January to September period to the previous one, average open interest has quadrupled.
Furthermore, compared to 2019, genuine interest has seen a staggering twelvefold increase, indicating a substantial uptick in market activity.
From Enron to Climate Change
Weather derivatives emerged in the late 1990s, partly driven by energy giant Enron. This unique financial market initially gained momentum as it attracted speculators seeking assets uncorrelated with broader financial markets.
However, it faced a decline in the aftermath of the 2007-2008 financial crisis. The current resurgence of weather derivatives can be attributed to the dual forces of climate change and the El Niño phenomenon, contributing to the hottest northern hemisphere summer ever recorded in 2023.
Mitigating Risk with Weather Derivatives
Unlike traditional insurance, weather derivatives do not necessitate proof of losses. These financial instruments pay based on predetermined indexes, such as temperature or rainfall.
Businesses often employ them to hedge against weather-related disruptions that could impact their operations. For instance, an energy company may purchase a temperature-indexed contract to safeguard against a warmer-than-average winter, which might lead to reduced natural gas sales.
If the weather exceeds the expected norms, the contract’s value appreciates, and compensation is offered upon settlement.
The New Normal in Climate
Climate change and concerns over energy supply stability are steering businesses’ extensive utilities towards weather derivatives as a means of proactive risk management.

As extreme weather events become more frequent and intense, market participants anticipate the continued growth of this financial tool.
“There is a general belief that extreme (weather) events are both going to become more common and more extreme,” stated Peter Keavey, the global head of energy and environmental products at CME Group, underlining the driving force behind the expanded use of weather derivatives in our changing world.
