IEX shares hit lower circuit after power regulator CERC approves electricity market coupling for DAM by Jan 2026, signaling rising competition.
📉 What Sparked the Sharp Drop?
On July 24, shares of Indian Energy Exchange (IEX) tanked 10%, triggering a lower circuit bound at ₹169.10 on the BSE and NSE. This sharp decline followed the Central Electricity Regulatory Commission (CERC) approving “market coupling” of the Day Ahead Market (DAM), scheduled for phased rollout starting January 2026.

🔍 What Is Market Coupling?
- Market coupling harmonises electricity trading by aggregating buy and sell bids across all power exchanges into a single pool.
- It establishes a uniform market clearing price (MCP) for all participants, eliminating price disparities between exchanges.
- The DAM will operate in a round‑robin mode, with each exchange taking turns as the Market Coupling Operator (MCO). Lexology+11Moneycontrol+11Upstox – Online Stock and Share Trading+11

✅ Final Verdict
IEX’s 10% sell-off reflects immediate investor panic over increased competition. However, with advance notice and a strong foundation—including leadership in real-time and green markets—IEX has room to reposition. The upcoming Q1FY26 earnings and commentary on market coupling readiness will be the next big litmus test.
