IEX Shares Crash 10% as CERC Clears New Rule

On Thursday, July 24, 2025, the IEX share price plunged 10% to the lowest limit of ₹169.10 on the stock market. The loss, which wiped out 10% of IEX's market capitalization in one day was a reaction to India's power regulator announcing a major change that could harm IEX's business. 

What Happened to IEX Share Price Today?

IEX shares crashed 10% to ₹169.10 in early trading after the Central Electricity Regulatory Commission (CERC) announced market coupling would be imposed in January 2026. The shares fell from the previous day's close of ₹187.85, marking one of the worst single-day returns of the stock.

Why IEX Share is Falling ??

Why iex is down? The main reason for this decline is due to a new regulation announced by CERC (Central Electricity Regulatory Commission). CERC's order makes it clear that Market Coupling will be implemented in Phase ->I by Jan 2026.

What is Market Coupling?

Market coupling is a new system where:

• All power exchanges in India will cooperate

• There will be one uniform price for electricity across all markets

• It is an economic model that is popular in energy markets to establish a single and uniform price for electricity at various trade platforms/exchanges

At the moment, the electricity market in India is dominated by IEX. This new model will provide a reasonable space for other exchanges to compete fairly.

How This Affects IEX's Business

IEX share fall reason is clear - the company will lose its current advantage:

• Lost Dominance : IEX currently has the majority of India's electricity spot trading

• Lower Market Share : This structural reform will threaten IEX's majority ownership

• Reduced Revenue : The firm stands to receive less revenue from transaction fees

• More Competition : Other power exchanges will now be competing on equal terms.

Expert Views on IEX Share News

Market experts are worried about IEX's future:

• Target Price Cut : Bernstein slashes target price to Rs 122 from the earlier target of ₹160

• Market Share Concerns : Analysts believe IEX will lose market share to competitors

• Revenue Impact : Lower transaction charges expected due to increased competition

One expert explained: "This move transfers price discovery from individual exchanges to a central system. This hurts IEX's dominance in setting electricity prices."

What Happens Next?

The new system will be rolled out in phases:

1. January 2026 : Day-ahead market coupling starts

2. Later : Real-time market coupling (timing not decided yet)

3. Rotation System : All existing power exchanges will serve as the Market Coupling Operator (MCO) on a rotational basis

Conclusion
