Imagine explaining this to someone 10 years ago:
“One day, you’ll be able to trade Mumbai’s rain.”
They’d probably think you’ve completely lost it.
Yet here we are.
Mumbai’s rainfall is now linked to a SEBI-regulated contract, with the city’s benchmark based on 30 years of IMD data. The average annual rainfall used for the contract is 2,206.7 mm and every 1 mm deviation can move the contract value by ₹50.
Which sounds wild until you realize how expensive rain actually is.
The 2005 Mumbai floods alone caused losses of over ₹10,000 crore and every monsoon disrupts transport, logistics, construction, businesses, and daily life across the city.
For decades, rain has been an unpredictable risk. Now, it’s becoming something that can be measured, managed, and traded.
A decade ago, people checked the weather forecast to plan their day.
Today, some people might check it to plan their trade. 📈
