Capital Economics says outage likely to have little impact on world economy
The global computer outage likely will have little impact on the world economy, according to forecasting firm Capital Economics, particularly because it hasn’t disrupted financial markets.
“While things are still very uncertain, we do not anticipate a major macroeconomic or financial market impact at this stage,” Jennifer McKeown, chief global economist at Capital Economics, said in a written comment. “It is encouraging from an economic standpoint that there has been little financial disturbance so far.”
The firm estimated in late 2022 that even a cyberattack that lasted several days would only shave global economic growth by about 0.2%.
“Given that this is not a cyberattack and has not affected all software by any stretch, the implications should be significantly smaller,” McKeown said.
Cybersecurity analyst calls outage historic mistake by CrowdStrike
Richard Stiennon, a cybersecurity industry analyst, said that this was a historic mistake by CrowdStrike.
“This is easily the worst faux pas, technical faux pas or glitch of any security software provider ever,” said Stiennon, who has tracked the cybersecurity industry for 24 years.
He said while the problem is an easy technical fix, it’s impact could be long lasting.
“It’s really, really difficult to touch millions of machines. And people are on vacation right now, so, you know, the CEO will be coming back from his trip to the Bahamas in a couple of weeks and he won’t be able to use his computers.”

CrowdStrike listed on the Nasdaq exchange five years ago. It reported last month that its revenue rose 33% in the last quarter from the previous quarter and that logged a net profit of $42.8 million, up from $491,000 in the first quarter of this year.
The company has a partnership with Amazon Web Services and its Falcon for Defender is designed to supplement Microsoft Defender to prevent attacks.
The firm said Friday’s global disruptions occurred when it deployed a faulty update to computers running Microsoft Windows. The issue was not a security incident or cyberattack, and a fix was on the way, it said.
