Chennai, one of India’s largest metropolitan and industrial centers, is uniquely exposed to rainfall variability due to its dependence on the Northeast Monsoon (September to December), which contributes the majority of the city’s annual rainfall. Chennai (Meenambakkam/ Nungambakkam IMD stations) records ~1400mm annual rainfall, annually with ~70% concentrated in September-December Unlike most Indian cities that receive substantial precipitation from the Southwest Monsoon, Chennai derives a significant share of its yearly rainfall from weather systems originating over the Bay of Bengal, including low-pressure systems, depressions, and cyclones. This concentration of rainfall within a relatively short season often results in pronounced intra-seasonal variability, creating financial and operational challenges for sectors such as urban infrastructure, construction, transportation, retail, logistics, hospitality, water management, insurance, and energy. 

Rainfall-based weather derivative contracts are introduced to provide market participants with an efficient mechanism to manage financial risks arising from fluctuations in rainfall. 

Futures contract based on rainfall as underlying parameter settles on measured precipitation at a specified reference station over a defined observation window, as notified by the Exchange. The contract provides a transparent, regulated, and exchange traded platform for hedging rainfall related financial exposure and facilitates efficient price discovery, with financial settlement and no physical delivery obligation. Thus contract will serve as an effective risk management instrument for participants exposed to rainfall variability and supports mitigation of weather related financial uncertainties using reliable rainfall data.
