Stock Exchanges Largely Run Smoothly After CrowdStrike Issues

Financial services firms globally worked Friday to cope with the outage in Microsoft (MSFT) Windows triggered by an update from CrowdStrike (CRWD), although stock exchanges like the Nasdaq Stock Market and the New York Stock Exchange operated without major problems.

Some bankers and traders had issues logging in to their company IT systems. Among those affected were workers at banking giant JPMorgan Chase (JPM) and Instinet, a broker controlled by Japan’s Nomura, according to The New York Times.

Most Stock Exchanges Unaffected by Outage

The London Stock Exchange said it had been hit, with RNS, its news feed of company statements, disrupted. The RNS feed is now “operating normally,” the exchange told Bloomberg in a statement, by early afternoon London time.

Some fund managers also said their customers had problems getting onto their sites.

“We are currently experiencing some issues with pages loading on our website due to the global Crowdstrike” issues, Vanguard UK said in a post in the social media platform X, although there were no such statements by the U.S. arm of the retail broker.

Exchanges otherwise were operating as normal. The New York Stock Exchange, Nasdaq, and European exchange operator Euronext were among those that told The Wall Street Journal they were operating normally.
