Agricultural commodity exchange NCDEX has introduced RAINMUMBAI, India’s inaugural SEBI-approved, exchange-traded weather derivatives contract, set to debut on May 29. This innovative contract aims to transform monsoon variability into a measurable and tradable financial risk under a regulated framework. Weather derivatives like this assist in managing risks associated with adverse weather conditions such as rainfall fluctuations.
The rainfall-based derivative is dependent on actual rainfall levels at a specific location over a defined period, as outlined by NCDEX. Rainfall measurements are conducted using rain gauges and automatic weather stations, following India Meteorological Department (IMD) norms on a 24-hour cycle. Developed with inputs from IIT Bombay and grounded in IMD data, this product allows participants to hedge financial exposure linked to rainfall fluctuations.
Dubbed ‘RAINMUMBAI,’ this derivative will monitor deviations in Mumbai’s rainfall from its long-period average during the monsoon season, based on a Cumulative Deviation Rainfall (CDR) model. The model utilizes IMD surface rainfall data and Automatic Weather Station observations from Santacruz and Colaba, benchmarked against a 30-year historical dataset. The instrument will offer cash-settled transactions, ensuring transparent and efficient risk management without physical loss assessment.
NCDEX highlights that ‘RAINMUMBAI’ caters to a diverse group of stakeholders, including farmers, construction firms, power utilities, logistics providers, and banks with agricultural loan portfolios. It serves as a risk management tool beyond traditional mechanisms like insurance and government relief measures. Arun Raste, Managing Director and CEO of NCDEX, emphasized the significance of this tool in managing monsoon uncertainties effectively.
Bikram Singh, Head of the Regional Meteorological Centre (RMC) at IMD, Mumbai, stressed the importance of reliable weather data for such financial instruments. He noted that IMD’s long-term datasets and observational systems play a crucial role in enabling transparent rainfall indices. The exchange will facilitate liquidity support through a designated market maker to enhance participation in the contract, marking a significant stride in India’s climate-risk management ecosystem.
