Synopsis : The National Commodity and Derivatives Exchange (NCDEX) has launched India’s first SEBI-approved exchange-traded weather derivative named RAINMUMBAI. The new rainfall-based futures contract is designed to help businesses and investors hedge financial risks arising from monsoon variability and extreme weather conditions.
The National Commodity and Derivatives Exchange (NCDEX) will officially launch RAINMUMBAI on May 29, 2026, marking the debut of India’s first exchange-traded weather derivative approved by the Securities and Exchange Board of India (SEBI).
The rainfall-linked futures contract has been developed in collaboration with the Indian Institute of Technology (IIT) Bombay and uses rainfall data provided by the India Meteorological Department (IMD).
RAINMUMBAI is a cash-settled parametric futures contract that allows market participants to hedge against financial losses caused by fluctuations in monsoon rainfall.
Unlike traditional insurance products, the contract does not require physical verification of losses or claims processing. Settlement is automatically determined using objective rainfall data.
The contract is based on a Cumulative Deviation Rainfall (CDR) index, which measures deviations between actual rainfall recorded in Mumbai and the city’s Long Period Average (LPA) monsoon rainfall level of 2,206.7 mm during the June-to-September monsoon season.
A positive CDR value indicates rainfall above historical averages, while a negative value reflects deficient rainfall.
NCDEX stated that the product aims to provide a transparent and efficient risk-management mechanism for weather-sensitive sectors.
The exchange identified agriculture, construction, logistics, retail, power utilities and financial institutions with agricultural loan exposure as key target users for the product.
India’s economy remains highly dependent on monsoon activity, with nearly 46% of the country’s workforce employed in agriculture and several industries exposed to climate-related disruptions.
NCDEX noted that India has suffered around $180 billion in losses from extreme weather events over the past three decades, highlighting the growing need for weather-linked financial hedging instruments.
The exchange described Mumbai as a suitable launch market because of the city’s high economic sensitivity to monsoon-related disruptions affecting transportation, retail activity, energy consumption and financial market operations.
The launch also follows regulatory changes made in 2024 when weather derivatives were formally included under the Securities Contracts (Regulation) Act, 1956 (SCRA), enabling commodity exchanges to introduce such products.
NCDEX said the RAINMUMBAI framework could eventually expand into rainfall derivatives for agricultural regions and temperature-linked contracts for northern India.
To trade RAINMUMBAI contracts, investors will require a demat and commodity trading account with a SEBI-registered broker offering access to the NCDEX platform.
The contracts will trade from Monday to Friday between 10:00 AM and 11:30 PM, with extended trading up to 11:55 PM during certain parts of the year.
NCDEX said the product has been designed primarily as a hedging and operational risk-management instrument rather than a speculative trading product.
The success of RAINMUMBAI and participation from weather-sensitive industries will likely determine the future expansion of India’s weather derivatives market.
