Indian Energy Exchange (IEX) shares tumbled by 28% to ₹135.26 on the NSE on Thursday, following the Central Electricity Regulatory Commission’s (CERC) official approval of market coupling for the country’s power sector, scheduled to start with the Day-Ahead Market in January 2026. This regulatory move comes just hours before IEX is set to announce its Q1 FY26 results, adding to investor unease about the company's short-term prospects. The decision, intended to streamline price discovery, has raised concerns among investors about IEX’s future competitiveness and business model.
