IEX share price was trading lower on Monday, January 19, after the Power Minister reiterated that there is no change in the government’s stance on market coupling. The statement dampened investor sentiment, as concerns around regulatory changes resurfaced ahead of a key tribunal hearing.

Why IEX Share Price Fell

The decline in IEX shares came as the Electricity Appellate Tribunal (APTEL) prepared to hear the long-pending market coupling matter later in the day. Market coupling is a proposed mechanism that could change how electricity prices are discovered across power exchanges. For IEX, which holds a dominant position in the power trading market, the proposal has raised fears of potential loss of market share.

Investors remain cautious, as clarity on the issue has been delayed for several months.

APTEL Hearing and CERC’s Stand

APTEL is hearing IEX’s plea seeking the withdrawal of the Central Electricity Regulatory Commission’s (CERC) July 2025 directive on day-ahead market coupling. In an earlier hearing, the tribunal had asked CERC to clarify whether it intended to withdraw the directive, but no final decision was reached.

Ahead of the current hearing, CERC issued a circular stating that its July 2025 communication should be treated as a “direction” and not an “order”. This distinction has added another layer of uncertainty to the case.

Earlier this month, CERC’s counsel had informed the tribunal that the regulator was open to taking instructions to withdraw the directive. The tribunal had indicated that if such intent was formally conveyed, the matter could be closed quickly.

IEX’s Objections to Market Coupling

IEX has argued that the market coupling directive is arbitrary and violates principles of natural justice. The exchange believes that market coupling would not bring meaningful benefits to the power market and would instead harm competition by reducing its market share.

The company has also pointed out that the July 2025 directive led to a sharp 29% fall in its share price in a single trading session, highlighting the material impact of regulatory uncertainty on investors.

Allegations Add to Investor Concerns

During earlier hearings, IEX had referred to a market regulator’s report alleging insider trading by certain officials, involving illegal gains of ₹173 crore. The exchange claimed that the market coupling proposal was tainted and part of a broader conspiracy, further intensifying scrutiny around the directive.

Conclusion

IEX shares remain under pressure as uncertainty over market coupling continues. While regulatory authorities have hinted at a possible withdrawal of the directive, the lack of a clear resolution has kept investors cautious. The outcome of the APTEL hearing will be crucial in determining the near-term direction of the stock and the future structure of India’s power trading market.
