IEX Shares Affected by Market Coupling Norms Approval
Imagine a marketplace where everyone buys and sells electricity.
Right now, there are different platforms for this, and the prices might vary.
A new rule is coming where all the platforms will share their buy and sell orders.
This helps find one fair price for electricity, no matter which platform you use.
This rule change is expected to negatively impact the Indian Energy Exchange (IEX).
It means that IEX might not be the only place to get the best prices anymore.
Shares of IEX went down when the news was announced.

Market coupling will aggregate buy/sell orders across power exchanges for uniform pricing.
