Shares of Indian Energy Exchange Ltd (IEX) witnessed a steep fall of 20%, hitting the lower circuit on Thursday, July 24, following reports that the Central Electricity Regulatory Commission (CERC) has approved a major change in how the Day-Ahead Market (DAM) will operate in the future.
The fall comes amid regulatory changes that could impact the dominant position of IEX in the power trading ecosystem.
What Triggered the Fall?
According to reports, CERC has cleared the implementation of market coupling in the Day-Ahead Market by January 2026. This marks the beginning of a new operational framework for India’s power exchanges.
In the new system, all participating power exchanges will follow a round-robin mechanism to act as Market Coupling Operators (MCOs). These operators will collect buy and sell bids across platforms and dispatch power accordingly, ensuring uniform prices across exchanges.

What Does Market Coupling Mean?
Under market coupling, power exchanges like IEX will no longer independently match bids and set prices. Instead, their role will be reduced to a platform for collecting bids, while pricing and allocation will be centrally managed by the designated MCO.
While this won’t impact end consumers immediately, it may bring long-term benefits like reduced power tariffs, greater price transparency, and improved efficiency in power distribution.
Investor Concerns
The move has raised concerns among investors regarding IEX’s future revenue and market dominance. Given IEX’s current stronghold in the power trading space, a reduction in its independent operational control could affect its business model and profitability.
Interestingly, despite this sharp drop, IEX shares had gained around 7.7% over the past year, indicating that the market had been optimistic until now.
What Lies Ahead?
With implementation expected by January 2026, companies in the power exchange business now have a timeline to adapt. How IEX responds to these structural changes will be critical for its long-term outlook.
