IEX Shares Surge on Market Coupling Hopes
The Indian Energy Exchange (IEX) is a company that helps buy and sell electricity.
Recently, its shares went up by a lot because people think a court might help them with a new rule.
This rule, called market coupling, is about how electricity prices are decided.
Right now, IEX is the biggest player in this market, but the new rule might change that.
The court is looking at this rule, and some people think the court might not like how the rule was made.
IEX says the rule is not fair and should be stopped.
Meanwhile, IEX's associate company, Indian Gas Exchange (IGX), is planning to go public by December 2026 to raise more money.
IGX is also doing well, with more gas being traded and higher profits compared to last year.
The court's decision and the IPO plans could be important for how electricity and gas are bought and sold in the future.
IEX shares jumped up to 14% during trading and ended 8% higher on hopes of relief in the market coupling case.
The Electricity Appellate Tribunal (APTEL) is hearing the case regarding the market coupling norms issued by the Central Electricity Regulatory Commission (CERC).
APTEL reportedly made strong remarks about how the coupling regulations were framed, suggesting potential issues with the process.
IEX maintains that the coupling framework is flawed and should be set aside, regardless of any insider trading findings.
The market coupling process, set to start in January 2026, would pool bids from all exchanges and announce a single market-cleared price, potentially reducing IEX's dominant position.
