Introduction
If you're currently in possession of IEX shares or contemplating putting the Indian Energy Exchange into your portfolio, recent events could have you feeling a little anxious. The Central Electricity Regulatory Commission (CERC) has proposed a transformative policy called market coupling, paving the way for uncertainty in the power trading market. With the share price of Indian Energy Exchange declining, it is reasonable to ask yourself: Is this a buy-the-dip opportunity, or is it a view of change? Let's understand what this means for you as an IEX investor.
What makes IEX run?
Indian Energy Exchange is the structure that powers electricity trading in India. It allows electricity sellers, such as power producers, to sell to buyers, which may consist of state utilities, industry, etc. IEX is not like a power plant; it does not, itself, generate electricity; IEX is simply a platform that collects a fee for each electricity transaction or trade. IEX enjoys more than 90% of the market share and has created a monopoly for electricity trading in India, siphoning an enormous piece of the profits from the transaction fees, equal to about 85% of total revenue in FY24. This monopoly has made substantial demand for IEX shares, which has caused both retail and institutional investors to favour IEX as an attractive, stable and resilient asset, and recently, growth potential in the energy market in India.
The CERC Curve
In June 2024, CERC announced that market coupling would be initiated for the day-ahead market as of January 2026. In this market coupling approach, IEX cedes its price-setting authority to a central authority that will take bids from IEX and other exchanges and set a uniform price based on an agreed-upon supply and demand. For you, this means that the liquidity and efficiency you have grown accustomed to on IEX as your preferred exchange could weaken, as buyers may search multiple exchanges for the best executed price, since the price will be identical across exchanges.

The IEX stock plunge
The market reacted with amazement. On July 24, 2025, IEX stock fell approximately 30%, and the India Energy Exchange share price tumbled from ₹200 to ₹140. Although it climbed to ₹141 on August 19, 2025, we must realise that the IEX share price drop comes from fears of decreased market share and revenue. As an IEX investor, you now face a reality where regulatory changes may set up hurdles to the organisation's growth path.
Keeping Yourself Updated
IEX is still a giant despite the headwinds. In July 2025, IEX recorded trading volumes of 12,664 million units, a 25.5% increase year-over-year from July 2024, and a 53% increase compared to real-time market volumes in the month. In a challenging pricing environment (we note that day-ahead market prices fell to ₹4.18/unit, a decrease of 16%), this will mean trade and volume increases. Performance in green energy continues to grow by 4% in this environment, which is noteworthy. These quarterly trading volumes indicate the operational performance of IEX despite the uncertainty of market coupling.
Risks
In addition to the potential of losing market price regulation (capitalising on this price difference and transaction fee possibility), IEX's competitors could further chip away at its market dominance. Some analysts perceive that due to the amount of work to implement market coupling ("79 items"). These will likely delay implementation until 2027, which allows time to determine how IEX adapts, perhaps through service innovations or market expansions.
Conclusion
Power demand in India is increasing rapidly, and with this growth, IEX's technology-enabled rented/disruption model, margins within the top end of the market, and long-term opportunities are attractive. While this expected volatility may prove unappealing for some shareholders, we recommend considering other energy stocks and building a diversified portfolio if you are risk-averse. Speak to your financial advisor about how many IEX shares you have within your objectives.
The stock price of the Indian Energy Exchange may experience some short-term pressure, but India's energy future is bright. Stay posted, remain patient, and you may be able to turn this tremor into an opportunity.
