NCDEX set to launch India's first exchange-traded weather derivatives "RAINMUMBAI"

New Delhi [India], May 21 (ANI): National Commodity Derivatives Exchange Limited (NCDEX) is set to launch RAINMUMBAI, the country's first exchange-traded weather derivatives contract, on May 29, 2026.
As per NCDEX, the initiative aims to transform monsoon variability from an unpredictable challenge into a measurable, manageable, and tradable financial risk within a regulated framework. The product is approved by the Securities and Exchange Board of India (SEBI) and developed in collaboration with the Indian Institute of Technology (IIT) Bombay, utilizing official data from the India Meteorological Department (IMD).
The futures contract is designed for a broad range of stakeholders with financial exposure to rainfall fluctuations, including farmers, construction companies, power utilities, logistics operators, and banks with agricultural loan portfolios.
Unlike traditional insurance mechanisms, this cash-settled derivative is tied to observed data, which eliminates the need for physical loss assessment and enables faster settlement cycles. The derivatives will utilize a daily rainfall data network from IMD surface observatories at Santacruz and Colaba, benchmarked against a 30-year historical dataset of the Long Period Average (LPA) from 1991 to 2020.
"India has lived with monsoon uncertainty for centuries. RAINMUMBAI provides every stakeholder with a regulated, scientific tool to manage this uncertainty. The contracts are based on a scientifically structured Cumulative Deviation Rainfall (CDR), which measures the deviation of actual rainfall from the Long Period Average (LPA) during the monsoon months (June to September). Built using daily rainfall data from the India Meteorological Department's (IMD) network of surface observatories and benchmarked against a robust 30-year historical dataset (1991-2020 LPA), the framework ensures transparency, consistency, and reliability," said Arun Raste, Managing Director and Chief Executive Officer of NCDEX.
NCDEX stated that the derivatives contract will come with a tick size of 1mm and a lot multiplier of Rs 50 per mm. Trading hours are scheduled from Monday to Friday between 10:00 AM and 11:30/11:55 PM, with a maximum order size capped at 50 lots. The operational model relies strictly on standardized scientific readings to calculate final settlement prices.
Bikram Singh, Head of the Regional Meteorological Centre (RMC) Mumbai at the IMD, emphasized the role of infrastructure in securing the transparency of the financial instrument.
"Reliable and standardized weather data is critical for the development of such financial instruments. IMD's observational infrastructure and long-term datasets provide a strong foundation for building credible and transparent rainfall indices. It is science meeting finance in a regulated marketplace," Singh said. (ANI)
