Nasdaq Nordic reports technical disturbance impacting NRT

Nasdaq Nordic reported a technical disturbance affecting its INET Nordic trading system, resulting in incorrect trade type assignments for auction trades. Specifically, all auction trades were erroneously classified as "Auction on Demand" rather than their specific trade types. This error prevented the proper updating of key market data metrics, including last price, high/low ranges, average price, and volume-weighted average price (VWAP).

The issue further impacted closing values for Nasdaq Nordic and Baltic equities and indices, potentially rendering them inaccurate. Nasdaq stated it would disseminate corrected closing prices for affected securities and indices via file download, as outlined in a market notice. Traders and investors relying on real-time or end-of-day data for decision-making may need to account for these discrepancies until the corrected data is processed.

Nasdaq attributed the disturbance to its General Collateral Financing (GCF) Production system and emphasized that the technical issue has since been resolved. For clarification on specific trades or system functionality, Nasdaq directed users to contact its Exchange Services team at +46 8 405 7700 or EMO@nasdaq.com. No further details about the root cause or duration of the disruption were provided in the notice.

As of March 5, 2026, no additional updates have been published regarding the incident's broader market impact. Investors are advised to monitor official Nasdaq communications for further clarification.
