IEX shares slide more than 4% after India’s Supreme Court clears CERC to draft market-coupling rules

AI Market Summary
India's Supreme Court declined to hear IEX's plea at this stage, allowing CERC to proceed with market-coupling regulations. The mechanism would pool orders across exchanges to produce a single market-clearing price, reducing IEX's standalone price-discovery power and potentially compressing its competitive moat. The ruling triggered a sharp drop in IEX shares, signalling heightened regulatory overhang for India's power-trading ecosystem.

India’s Supreme Court declined to hear Indian Energy Exchange’s (IEX) appeal on market-coupling regulation, affirming the Central Electricity Regulatory Commission’s (CERC) authority to push the mechanism. Since 2024, CERC has cleared a shadow pilot led by the Grid Controller of India, with IEX, PXIL and HPX rotating as the market-coupling operator. From January 2026, the Grid Controller of India is set to aggregate prices across power trading platforms and publish a single reference price. The ruling weakens IEX’s pricing power and independent role in spot power trading, sending the stock down more than 4% in a single session.
