India's Largest Commodity Exchange Halts Trading

India’s largest commodity exchange, the Multi Commodity Exchange of India Ltd. (MCX), halted trading for more than three hours on Oct. 28, 2025, after a technical issue left participants unable to execute orders or access live prices. MCX said trading would be restarted from a disaster recovery site, a backup system intended to restore functionality while the problem is investigated and fixed. Separately, the Canadian Investment Regulatory Organization (CIRO) issued multiple trading‑halt notices on Oct. 27–28, 2025, temporarily suspending specified securities as part of its oversight of dealers and trading on Canadian debt and equity marketplaces. The incidents highlight how exchanges and regulators use trading suspensions to protect fair and orderly markets during outages and sensitive developments.
