RAINMUMBAI and the Emerging Role of Weather Derivatives in India

Context

Recently, the National Commodity and Derivatives Exchange (NCDEX) launched “RAINMUMBAI”, India’s first SEBI-approved exchange-traded weather derivatives contract, aimed at providing a financial risk-management tool against uncertainties arising from rainfall variability and monsoon fluctuations.

About RAINMUMBAI

1. The contract has been developed in collaboration with Indian Institute of Technology Bombay using Mumbai’s historical rainfall patterns.
2. It will track deviations between actual rainfall and the city’s Long Period Average (LPA) during the monsoon season.
3. Rainfall observations recorded by the India Meteorological Department (IMD), including data from Santacruz, Colaba and Automatic Weather Stations (AWS), will be used for settlement purposes.
4. Unlike conventional insurance products, payouts under weather derivatives are linked directly to observed weather data instead of physical loss assessment, ensuring faster settlement and lower operational complexity.
5. The contract is expected to benefit sectors such as agriculture, logistics, tourism, construction, energy and power generation, where economic activity is significantly influenced by weather conditions.
6. Trading will be permitted only during the monsoon months of June, July, August and September, in line with Mumbai’s rainfall cycle.
7. The derivative contract will be cash-settled and traded in lots valued at ₹50 per millimetre of rainfall.
8. Trading hours for the contract have been fixed from 10:00 a.m. to 11:30 p.m. on weekdays.

Derivatives

2. The underlying asset may include commodities, stocks, bonds, currencies, interest rates or market indices.
3. Such instruments are commonly used for risk hedging, speculation and portfolio management without direct ownership of the underlying asset.
